THAT THE CELESTIAL BODIES MAKE NO IMPRESSION ON OUR INTELLECTS
[1] From the things set forth earlier it is immediately evident that celestial bodies cannot be causes of events which go on in the understanding. Indeed, we have already shown that the order of divine providence requires the lower things to be ruled and moved by the higher ones. But the understanding surpasses all bodies in the order of nature, as is also clear from what we have said before. So, it is impossible for celestial bodies to act directly on the intellect. Therefore, they cannot be the direct cause of things that pertain to understanding.
[2] Again, no body acts except through motion, as is proved in Physics VIII [6]. But things that are immovable are not caused by motion, for nothing is caused by the motion of an agent, unless the agent moves a passive subject during the motion. So, things that are utterly apart from motion cannot be caused by the celestial bodies. But things that are in the area of understanding are entirely apart from motion, properly speaking, as is evident from the Philosopher, in Physics VII [3]. On the contrary, “through being undisturbed by motions, the soul becomes prudent and knowing” as is stated in the same place. Therefore, it is impossible for celestial bodies to be the direct cause of things that pertain to understanding.
[3] Besides, if nothing is caused by a body unless the body is moved while the motion is going on, it is necessary for everything that receives an impression from a body to be moved. Now, nothing is so moved except a body, as is proved in Physics VI [4]. So, everything that receives an impression from a body must be a body, or some power of a body. Now, we showed in Book Two that the intellect is neither a body nor a bodily power. Therefore, it is impossible for the celestial bodies directly to make an impression on the intellect.
[4] Moreover, everything that is moved by another thing is reduced by it from potency to act. But nothing is reduced by a thing from potency to act unless that thing is actual. So, every agent and mover must be in some way actual, in regard to the effects to which the passive and movable subject is in potency. Now, the celestial bodies are not actually intelligible, for they are certain individual, sensible things. And so, since our intellect is not in potency to anything except actual intelligibles, it is impossible for celestial substances directly to act on the intellect.
15] Furthermore, the proper operation of a thing depends on its nature, which, in things that are generated, is acquired, along with the proper operation, through the process of generation. This is clear in the case of heavy and light things, which immediately at the end of the process that generates them possess their proper motion unless there be some impediment. Because of this the generating agent is called a mover. So, that which in regard to the beginning of its nature is not subject to the actions of celestial bodies cannot be subject to them in regard to its operation. Now, man’s intellectual nature is not caused by any corporeal principles, but is of completely extrinsic origin, as we proved above. Therefore, the operation of the intellect does not come directly under the celestial bodies.
[6] Again, effects caused by celestial motions are subject to time, which is “the measure of the first celestial motion.” And so, events that abstract from time entirely are not subject to celestial motions. But the intellect in its operation does abstract from time, as it does also from place; in fact, it considers the universal which is abstracted from the here and now. Therefore, intellectual operation is not subject to celestial motions.
[7] Besides, nothing acts beyond the capacity of its species. But the act of understanding transcends the species and form of every sort of bodily agent, since every corporeal form is material and individuated, whereas the act of understanding is specified by its object which is universal and immaterial. As a consequence, no body can understand through its corporeal form. Still less, then, can any body cause understanding in another being.
[8] Moreover, a being cannot be subject to its inferiors by the same part whereby it is united to its superiors. But our soul is united to the intellectual substances, which are superior to the celestial bodies in the order of nature, by virtue of the part which is the understanding. In fact, our soul cannot understand unless it receives intellectual light from those substances. Therefore, it is impossible for intellectual operation directly to be subject to the celestial motions.
[9] Furthermore, our confidence in this view will be increased if we consider the statements of the philosophers on the point. As a matter of fact, the ancient natural philosophers, like Democritus, Empedocles, and those of similar persuasion, claimed that understanding does not differ from sense perception, as is evident from Metaphysics IV [5] and from Book III of On the Soul [3]. And so, the conclusion was made that, since sensation is a bodily power depending on changes in bodies, the same thing is also true of understanding. For this reason, they said that intellectual operation results from the motion of the celestial bodies, because change in lower bodies results from change in the higher bodies. According to a passage in Homer: “So understanding in gods and in earthly men is like the daylight which the father of men and gods brings down”; the reference is to the sun, or, better, to Jupiter, whom they called the highest god, understanding him to be the whole heavens, as is clear from Augustine in his City of God [IV, 11].
[10] Next came the opinion of the Stoics, who said that intellectual knowledge is caused by the fact that the images of bodies are impressed on our minds, as a sort of mirror or as a page receives the letters imprinted on it without its doing anything; as Boethius reports in Book V of the Consolation. According to their view, it followed that intellectual notions are impressed on us chiefly by an impression from the celestial bodies. Hence, the Stoics were the ones who especially asserted that the life of man is directed by a fatal necessity.
However, this theory appeared false, as time went on, as Boethius says in the same place, for the understanding combines and separates, compares the highest things with the lowest, and knows universals and simple forms that are not found in bodies. So, it is obvious that the understanding is not simply receptive of bodily images, but has a power higher than bodies, since external sensation which is only receptive of bodily images does not encompass the actions mentioned above.
[11] Now, all the philosophers who followed distinguished understanding from sense perception and attributed the cause of our knowledge not to bodies, but to immaterial things. Thus, Plato claimed that the cause of our knowledge is the Ideal Forms; while Aristotle said that it is the agent intellect.
[12] From all these views we may gather that the assertion that the celestial bodies are the cause of our act of understanding is a consequence of the opinion of those who claimed that understanding does not differ from sensation, as is clear from Aristotle in his book On the Soul [III, 3]. Now, it has been shown that this opinion is false. So, it is also obvious that the opinion which asserts that celestial bodies are directly the cause of our act of understanding is false.
[13] Hence, Sacred Scripture also ascribes the cause of our understanding, not to any body but to God: “Where is God, Who made me, Who gives songs in the night; Who teaches us more than the beasts of the earth, and instructs us more than the fowls of the air?” (Job 35:10-11). Again, in the Psalm (93:10): “He who teaches man knowledge.”
[14] However, we should note that, though celestial bodies cannot be directly the causes of our understanding, they may do something indirectly in regard to it. For, although the understanding is not a corporeal power, the operation of understanding cannot be accomplished in us without the operation of corporeal powers: that is, the imagination, the power of memory, and the cogitative power, as is evident from preceding explanations. And as a result, if the operations of these powers are blocked by some indisposition of the body, the operation of the intellect is impeded, as is evident in demented and sleeping persons, and in others similarly affected. And that is why even the good disposition of the human body makes one able to understand well, for, as a result of this, the aforesaid powers are in a stronger condition. Thus it is stated in Book II of On the Soul [9] that we observe that “men with soft flesh are well endowed mentally.”
Now, the condition of the human body does come under the influence of celestial motions. In fact, Augustine says, in the City of God V, that “it is not utterly absurd to say that certain influences of the stars are able to produce differences in bodies only.” And Damascene says, in Book II [De fide orthodoxa], that “different planets establish in us diverse temperaments, habits and dispositions.”“So, the celestial bodies work indirectly on the good condition of understanding. Thus, just as physicians may judge the goodness of an intellect from the condition of its body, as from a proximate disposition, so also may an astronomer judge from the celestial motions, as the remote cause of such dispositions. In this way, then, it is possible that there is some truth in what Ptolemy says in his Centiloquium: “When, at the time of a man’s birth, Mercury is in conjunction with Saturn and is itself in a strong condition, it gives inwardly to things the goodness of understanding.”
Chapter 85
THAT THE CELESTIAL BODIES ARE NOT THE CAUSES OF OUR ACTS OF WILL AND CHOICE
[1] It further appears from this that the celestial bodies are not the causes of our acts of will or of our choices.
[2] Indeed, the will belongs in the intellectual part of the soul, as is evident from the Philosopher in Book III of On the Soul. So, if celestial bodies cannot directly make an impression on our intellect, as we showed, then neither will they be able to make an impression directly on the will.
[3] Again, every choice and act of will is caused immediately in us from an intelligible apprehension, for the intellectual good is the object of the will, as is clear from Book III of On the Soul [10]. For this reason, perversity cannot result in the act of choice, unless the intellectual judgment is defective in regard to the particular object of choice, as is evident from the Philosopher in Ethics VII [3]. But the celestial bodies are not the cause of our act of understanding. Therefore, they cannot be the cause of our act of choice.
[4] Besides, whatever events occur in these lower bodies as a result of the influence of celestial bodies happen naturally, because these lower bodies are naturally subordinated to them. So, if our choices do occur as a result of the impression of celestial bodies, they will have to occur naturally; that is to say, a man might choose naturally to have his operations go on, just as brutes are involved in operations by natural instinct, and as inanimate bodies are moved naturally. In that case, there would not be choice and nature, as two active principles, but only one, and that is nature. The contrary of this view is evident from Aristotle, in Physics II [5]. Therefore, it is not true that our choices originate from the influence of the celestial bodies.
[5] Moreover, things that are done naturally are brought to their end by determinate means, and so they always happen in the same way, for nature is determined to one result. But human choices tend to their end in various ways, both in moral actions and in artistic productions. Therefore, human choices are not accomplished by nature.
[6] Furthermore, things that are done naturally are done rightly in most cases, for nature does not fail, except in rare cases. So, if man were to choose naturally, his choices would be right in most cases. Now, this is evidently false. Therefore, man does not choose naturally. But he would have to ff he chose as a result of the impulsion of celestial bodies.
[7] Again, things that belong to the same species do not differ in their natural operations which result from the nature of their species. Thus, every swallow builds its nest in the same way, and every man understands naturally known first principles in the same way. Now, choice is an operation resulting from the species of man. So, if man were to choose. naturally, then all men would have to choose in the same way. This is clearly false, both in moral and in artistic actions.
[8] Besides, virtues and vices are the proper principles for acts of choice, for virtues and vices differ in the fact that they choose contraries. Now, the political virtues and vices are not present in us from nature but come from custom, as the Philosopher proves, in Ethics II [1], from the fact that whatever kind of operations we have become accustomed to, and especially from boyhood, we acquire habits of the same kind. And so, our acts of choice are not in us from nature. Therefore, they are not caused from the influence of celestial bodies, according to which things occur naturally.
[9] Moreover, celestial bodies make no direct impression, except on bodies, as we showed. So, if they are the cause of our acts of choice, this will be either because they influence our bodies, or because they influence external things. But in neither way can they be an adequate cause of our act of choice. In fact, it is not an adequate cause of our choice, for some corporeal things to be externally presented to us; for it is clear that on encountering some pleasurable object, say an item of food or a woman, the temperate man is not moved to choose it, but the intemperate man is moved. Likewise, whatever change might take place in our body as a result of the influence of a celestial body, it would not suffice to cause our choice, because there are no other results from this in us than certain passions, more or less strong. But passions, whatever their strength, are not an adequate cause for choice, since by the same passions an incontinent man is led to follow them by choice, while a continent man is not so induced. Therefore, it cannot be said that celestial bodies are the causes of our acts of choice.
[10] Furthermore, no power is given anything unless it has a use. But man has the power of judging and deliberating on all the things that may be done by him, whether in the use of external things or in the entertaining or repelling of internal passions. Of course, this would be useless if our choice were caused by celestial bodies which do not come under our control. Therefore, celestial bodies are not the cause of our act of choice.
[11] Again, man is naturally a political animal, or a social one. This is apparent, indeed, from the fact that one man is not sufficient unto himself if he lives alone, because nature provides but few things that are sufficient for man. Instead, it gives him reason whereby he may make ready all the things needed for life, such as food, clothing, and the like; one man is not sufficient to do all these things. So, to live in society is naturally implanted in man. But the order of providence does not take away from a thing what is natural to it, but provides for each thing in accord with its nature, as is evident from what we have said. Therefore, man is not so ordered by the order of providence that his social life is taken away. Now, it would be removed if our acts of choice arose from impressions due to the celestial bodies, as do the natural instincts of other animals.
[12] Besides, it would be useless for laws and rules of living to be promulgated if man were not master of his own choices. Useless, too, would be the employment of punishments and rewards for good or evil deeds, in regard to which it is not in our power to choose one or the other. In fact, if these things disappear, social life is at once corrupted. Therefore, man is not so established by the order of providence that his choices originate from the motions of the celestial bodies.
[13] Moreover, men’s choices are made in regard to goods and evils. So, if our choices originated from the motions of the stars, it would follow that the stars would be the direct cause of evil choices. But an evil thing has no cause in nature, since evil results from a defect of a cause and has no direct cause, as we showed above. Therefore, it is not possible for our choices to originate directly and of themselves from celestial bodies as causes.
[14] Now, someone might be able to oppose this argument by saying that every bad choice arises from a good that is desired, as we showed above. For instance, the choice of an adulterer arises from the desire for a pleasurable good associated with sexual activity, and some star moves him toward this universal good. As a matter of fact, this is necessary for the accomplishment of the generating of animals, and this common good should not be set aside because of the particular evil of this person who makes a bad choice as a result of such prompting.
[15] But this argument is not adequate if celestial bodies are claimed to be the direct cause of our choices, in the sense that they make direct impressions on the intellect and will. For the impression of a universal cause is received in any being according to the mode of that being. So, the influence of a star, that impels toward the pleasure associated with the generative act will be received in any being according to its own mode. Thus we observe that different animals have different times and various ways of reproducing, according to what befits their nature, as Aristotle says in his treatise on the History of Animals [V, 8]. So, intellect and will are going to receive the influence of this star according to their own mode. But, when an object is desired in accordance with the mode of intellect and reason, there is no sin in the choice; in fact, a choice is bad, always because it is not in accord with right reason. Therefore, if celestial bodies were the cause of our choices, there would never be a bad choice for us.
[16] Moreover, no active power extends to effects that are beyond the species and nature of the agent, for every agent acts by virtue of its form. But the act of willing surpasses every bodily species, as does the act of understanding. Indeed, just as we understand universals, so also is our will attracted to the universal object; for example, “we hate every kind of thief,” as the Philosopher says in his Rhetoric [II, 4]. Therefore our will-act is not caused by a celestial body.
[17] Furthermore, things that are related to an end are proportioned to that end. But human choices are ordered to felicity as their ultimate end. Of course, it does not consist in any corporeal goods but in the union of the soul with divine things by way of understanding, as we showed above, both according to the view of faith and according to the opinions of the philosophers. Therefore, celestial bodies cannot be the cause of our acts of choice.
[18] Hence it is said: “Be not afraid of the signs of heaven which the heathens fear; for the laws of people are vain” (Jer. 10:2-3).
[19] By this conclusion the theory of the Stoics is also refuted, for they claimed that all our acts, and even our choices, are ordered by the celestial bodies. This is also said to have been the position of the ancient Pharisees among the Jews. The Priscillianists, too, shared this error, as is stated in the book On Heresies [Augustine, 70].
[20] It was also the opinion of the old natural philosophers who claimed that sensation and understanding did not differ. Thus, Empedocles said that “the will is increased in men, as in other animals, in respect to what is present”; that is, according to the present instant resulting from the celestial motion that causes time, as Aristotle reports it in his book On the Soul [III, 3].
[21] Yet we should note that, though celestial bodies are not directly the cause of our choices, in the sense of directly making impressions on our wills, some occasion for our choices may be indirectly offered by them, because they do make an impression on bodies, and in a twofold sense. In one way, the impressions of the celestial bodies on external bodies are for us the occasion of a certain act of choice; for instance, when the atmosphere is disposed to severe cold by the celestial bodies, we choose to get warmed near a fire or to do other such acts which suit the weather. In a second way, they make an impression on our bodies; when a change occurs in them, certain movements of the passions arise in us; or we are made prone by their impressions to certain passions, as the bilious are prone to anger; or again, some bodily disposition that is an occasion for an act of choice may be caused in us by their impression, as when, resulting from our illness, we choose to take medicine. At times, too, a human act may be caused by the celestial bodies, in the sense that some people become demented as a result of a bodily indisposition and are deprived of the use of reason. Strictly speaking, there is no act of choice for such people, but they are moved by a natural instinct, as are brutes.
[22] Moreover, it is plain and well known by experience that such occasions, whether they are external or internal, are not the necessary cause of choice, since man is able, on the basis of reason, either to resist or obey them. But there are many who follow natural impulses, while but few, the wise only, do not take these occasions of acting badly and of following their natural impulses. This is why Ptolemy says, in his Centiloquium: “the wise soul assists the work of the stars”; and that “the astronomer could not give a judgment based on the stars, unless he knew well the power of the soul and the natural temperament”; and that “the astronomer should not speak in detail on a matter, but in general.” That is to say, the impression from the stars produces its result in most people who do not resist the tendency that comes from their body, but it is not always effective, for, in one case or another a man may resist, perhaps, the natural inclination by means of reason.
Chapter 86
THAT THE CORPOREAL EFFECTS IN THINGS HERE BELOW DO NOT NECESSARILY RESULT FROM THE CELESTIAL BODIES
[1] Not only is it impossible for the celestial bodies to impose necessity on human choice; in fact, not even corporeal effects in things here below necessarily result from them.
[2] For the impressions of universal causes are received in their effects according to the mode of the recipients. Now, these lower things are fluctuating and do not always maintain the same condition: because of matter which is in potency to many forms and because of the contrariety of forms and powers. Therefore, the impressions of celestial bodies are not received in these lower things by way of necessity.
[3] Again, an effect does not result from a remote cause unless there be also a necessary intermediate cause; just as in syllogisms, from a necessary major and a contingent minor, a necessary conclusion does not follow. But celestial bodies are remote causes, whereas the proximate causes of lower effects are the active and passive powers in these lower things, which are not necessary causes, but contingent, for they may fail in a few instances. So, effects in these lower bodies do not follow of necessity from the motions of the celestial bodies.
[4] Besides, the motion of the celestial bodies always is in the same mode. So, if the effect of the celestial bodies on these lower ones came about from necessity, the events in lower bodies would always happen in the same way. Yet they do not always occur in the same way, but in most cases. So, they do not come about by necessity.
[5] Moreover, it is not possible for one necessary thing to come to be out of many contingent things, because, just as any contingent thing of itself can fall short of its effect, so, too, all of them may together. Now, it is obvious that the individual effects that are accomplished in these lower things, as a result of the impression of celestial bodies, are contingent. Therefore, the combination of these events that occur in lower things as a result of the impression of celestial bodies is not a necessary one, for it is plain that any one of them may be prevented from happening.
[6] Moreover, the celestial bodies are agents in the order of nature; they need matter on which to act. So, the need for matter is not removed as a result of the action of celestial bodies. Now, the matter on which the celestial bodies act consists of the lower bodies which, being corruptible in their nature, may be just as able to fail in their operations as they are able to fail in their being. Thus, their nature has this characteristic: they do not produce their effects by necessity. Therefore, the effects of the celestial bodies do not come about by necessity, even in the lower bodies.
[7] But someone will say, perhaps, that the effects of the celestial bodies must be accomplished. Yet, possibility is not removed from the lower bodies by this fact, because each effect is in potency before it comes about. So, it is then called possible, but when it now becomes actual, it passes from possibility to necessity. All of this comes under the control of the celestial bodies; and so, the fact that the effect is at one time possible is not removed in this way, even though it is necessary that this effect be produced at another time. Indeed, this is the way that Albumasar, in his book, Introduction to Astronomy, tries to defend the possible.
[8] But one cannot defend this meaning of the possible. For there is a sort of possibility that depends on what is necessary. Indeed, what is necessary in regard to actual being must be possible in regard to being; and what is not possible in relation to being is impossible in regard to being; and what is impossible in regard to being is necessarily nonbeing. Therefore, what is necessary in relation to being is necessary in relation to non-being. But this is impossible. So, it is impossible for something to be necessary in relation to being, yet not possible in regard to this being. Therefore, possible being follows from necessary being.
[9] As a matter of fact, we do not have to defend this meaning of possible against the statement that effects are caused by necessity, but, rather, the possible that is opposed to the necessary, in the sense that the possible is called that which can be, and also not be. Now, a thing is not called possible, or contingent, in this way from the sole fact that it is at one time in potency and at another time in act, as the preceding answer takes it. In fact, in that preceding sense there is possibility and contingency even in celestial motions, for there is not always an actual conjunction or opposition of the sun or moon. Rather, it is sometimes actually so, sometimes potentially so; yet these events are necessary, for demonstrations of such events may be given. But the possible, or contingent, that is opposed to the necessary has this characteristic: it is not necessary for it to happen when it is not. This is indeed so, because it does not follow of necessity from its cause. Thus, we say that Socrates will sit is a contingent fact, but that he. will die is necessary, because the second of these facts follows necessarily from its cause, whereas the first does not. So, if it follows necessarily from the celestial motions that their effects will occur at some time in the future, then the possible and contingent that is opposed to the necessary is thereby excluded.
[10] Moreover, we should note that, in order to prove that the effects of the celestial bodies come about by necessity, Avicenna uses an argument like this in his Metaphysics [X, 1]. If any effect of the celestial bodies is blocked, this must be due to some voluntary or natural cause. But every voluntary or natural cause is reducible to some celestial source. Therefore, even the blocking of the effects of the celestial bodies results from some celestial sources. So, if the entire order of celestial things be taken together, it is impossible for its effect ever to fail to come about. Hence he concludes that the celestial bodies produce necessarily the effects which must occur in these lower bodies, both the voluntary and the natural ones.
[11] But this way of arguing, as Aristotle says in Physics [II, 4], was used by some of the ancients who denied chance and fortune on the basis of the view that there is a definite cause for every effect. If the cause be granted, then the effect must be granted. Thus, since everything occurs by necessity, there is nothing fortuitous or by chance.
[12] He answers this argument, in Metaphysics VI [2-3], by denying two propositions which the argument uses. One of these is: “if any cause be granted, it is necessary to grant its effect.” Indeed, this is not necessary in the case of all causes, for a certain cause, though it may be the direct, proper and sufficient cause of a given effect, may be hindered by the interference of another cause so that the effect does not result. The second proposition that he denies is: “not everything that exists in any way at all has a direct cause, but only those things that exist of themselves; on the other hand, things that exist accidentally have no cause.” For instance, there is a cause within a man for the fact that he is musical, but there is no cause for the fact that he is at once white and musical. As a matter of fact, whenever plural things occur together because of some cause they are related to each other as a result of that cause, but whenever they occur by accident they are not so related to each other. So, they do not occur as a result of a cause acting directly; their occurrence is only accidental. For instance, it is an accident to the teacher of music that he teaches a white man; indeed, it is quite apart from his intention; rather, he intends to teach someone who is capable of learning the subject.
[13] And thus, given a certain effect, we will say that it had a cause from which it did not necessarily follow, since it could have been hindered by some other accidentally conflicting cause. And even though it be possible to trace this conflicting cause back to a higher cause, it is not possible to trace this conflict, which is a hindrance, back to any cause. Thus, it cannot be said that the hindrance of this or that effect proceeds from a celestial source. Hence, we should not say that the effects of celestial bodies come about in these lower bodies as a result of necessity.
[14] Hence, Damascene says, in Book II [De fide orthodoxa], that “the celestial bodies are not the cause of any process of generating things that come into being, or of the process of corrupting things that are corrupted”; that is to say, these effects do not come about of necessity from them.
[15] Aristotle also says, in On Sleep II, that “of those signs which occur in bodies, and even of the celestial signs, such as movements of water and wind, many of their results do not come about. For, if another movement occurs, stronger than the one which is a sign of the future, then the event does not happen; just as many of our well laid plans, which were suitable to be accomplished, come to no result, because of the interference of higher powers.”
[16] Ptolemy, too, in his Fourfold Work, says: “Again, we should not think that higher events proceed inevitably, like things that happen under divine control and which can in no way be avoided, nor as things which come about truly and of necessity. He also says in the Centiloquium: “These prognostications that I give you are midway between the necessary and the possible.”
Chapter 87
THAT THE MOTION OF A CELESTIAL BODY IS NOT THE CAUSE OF OUR ACTS OF CHOICE BY THE POWER OF ITS SOUL MOVING US, AS SOME SAY
[1] However, we should note that Avicenna maintains that the motions of the celestial bodies are also the causes of our acts of choice, not simply as occasions, as was said above, but directly. For he claims that the celestial bodies are animated. Hence, since celestial motion is from a soul and is the motion of a body, therefore, just as it is a bodily motion with the power of causing change in bodies, so as a motion from the soul it must have the power to make an impression on our souls. And thus, the celestial motion is the cause of our acts of will and choice. On this point also he seems to return to the theory of Albumasar, in his Introduction I.
[2] But this theory is not reasonable. Every effect proceeding through an instrument from an efficient cause must be proportionate to the instrument, as also to the agent, for we cannot use just any instrument for any effect. Hence, a result cannot be accomplished by means of an instrument if the action of the instrument in no way covers the result. Now, the action of a body in no way extends to the production of a change of understanding and will, as we showed, unless, perchance, by accident, through a change in the body, as we said before. So, it is impossible for the soul of a celestial body, if it be animated, to make an impression on the intellect and will by means of the motion of a celestial body.
[3] Again, a particular agent cause, when acting, bears a likeness to the universal agent cause and is patterned on it. But, if a human soul were to impress another human soul through a corporeal operation, as when it reveals its thought by means of meaningful speech, the bodily action initiated by one soul does not reach the other soul without the mediation of its body. In fact, the spoken word moves the auditory organ, and then, having been so perceived by the sense power, it extends its message to the understanding. So, if the celestial soul makes an impression on our souls through bodily movement, that action will not reach our soul without making a change in our body. Now, this is not a cause of our acts of choice, but simply an occasion, as is clear from the foregoing. Therefore, celestial motion will not be a cause of our act of choice, except as a mere occasion.
[4] Besides, since the mover and the thing moved must be simultaneous, as is proved in Physics VII the motion must extend in a definite order, from the first mover to the last thing that is moved; that is, such that the mover moves what is far away from it by means of what is near to it. Now, our body is nearer than our soul is to the celestial body which is asserted to be moved by a soul joined to it, for our soul has no relation to a celestial body except through our body. This is evident from the fact that separate intelligences have no relation to a celestial body, unless, perhaps, that of a mover to a thing moved. So, a change in a celestial body, initiated by its soul, does not reach our soul except through the mediation of our body. But our soul is not moved when our body is moved, except accidentally; nor does choice result from a change in our body, except by way of occasion, as we said. Therefore, celestial motion, by virtue of the fact that it is from a soul, cannot be the cause of our act of choice.
[5] Moreover, according to the theory of Avicenna and some other philosophers, the agent intellect is a separate substance that acts on our souls by making potentially understood things to be actually understood. Now, this is done by abstraction from all material conditions, as is evident from our explanations in Book Two. So, that which acts directly on the soul does not act on it through corporeal motion, but, rather, through abstraction from everything corporeal. Therefore, the soul of the heavens, if it be animated, cannot be the cause of our acts of choice or understanding through the motion of the heavens.
[6] It is also possible to prove by the same arguments that the motion of the heavens is not the cause of our acts of choice by means of separate substances, if someone claims that the heavens are not animated, but moved by a separate substance.
Chapter 88
THAT SEPARATE CREATED SUBSTANCES CANNOT BE DIRECTLY THE CAUSE OF OUR ACTS OF CHOICE AND WILL, BUT ONLY GOD
[1] Now, we must not think that the souls of the heavens, if there be such, or any other created, separate, intellectual substances can directly insert a will-act into us or cause our act of choice to occur.
[2] For the actions of all creatures are embraced under the order of divine providence, so they cannot operate outside its laws. But it is the law of providence that everything be moved immediately by its proximate cause. So, unless such an order were obeyed, a superior created cause could neither move nor do anything. Now, the proximate mover of the will is the good as apprehended, which is its object, and it is moved by it, just as sight is by color. So, no created substance can move the will except by means of a good which is understood. Now, this is done by showing it that something is a good thing to do: this is the act of persuading. Therefore, no created substance can act on the will, or be the cause of our act of choice, except in the way of a persuading agent.
[3] Again, a thing is by nature capable of being moved by, and of undergoing a passion from, an agent with a form by which the thing can be reduced to act, for every agent acts through its form. But the will is reduced to act by the desirable object which gives rest to its desire. Now, the will’s desire finds rest in the divine good only, as in its ultimate end, as is evident from what we said above. Therefore, God alone can move the will in the fashion of an agent.
[4] Besides, as natural inclination in an inanimate thing, which is also called natural appetite, is related to its proper end, so also is the will, which is also called intellectual appetite, in an intellectual substance. Now, to give natural inclinations is the sole prerogative of Him Who has established the nature. So also, to incline the will to anything, is the sole prerogative of Him Who is the cause of the intellectual nature. Now, this is proper to God alone, as is evident from our earlier explanations. Therefore, He alone can incline our will to something.
[5] Moreover, the violent, as is said in Ethics III [1], is “that whose principle is outside; the patient making no contribution of force.” So, if the will is moved by some external principle, the motion will be violent. Now, I am talking about being moved by some external principle which moves in the way of an agent, and not in the way of an end. But the violent is incompatible with the voluntary. So, it is impossible for the will to be moved by an extrinsic principle as by an agent; rather, every movement of the will must proceed from within. Now, no created substance is joined to the intellectual soul in regard to its inner parts, but only God, Who is alone the cause of its being and Who sustains it in being. Therefore, by God alone can voluntary movement be caused.
[6] Furthermore, violent movement is opposed to natural and voluntary movement, because both of the latter must arise from an intrinsic source. The only way in which an external agent moves a thing naturally is by causing an intrinsic principle of motion within the movable thing. Thus, a generating agent, which gives the form of weight to a heavy generated body, moves it downward in a natural way. No other extrinsic being can move a natural body without violence, except perhaps accidentally, by removing an impediment, and this uses a natural motion, or action, rather than causes it. So, the only agent that can cause a movement of the will, without violence, is that which causes an intrinsic principle of this movement, and such a principle is the very power of the will. Now, this agent is God, Who alone creates a soul, as we showed in Book Two. Therefore, God alone can move the will in the fashion of an agent, without violence.
[7] Hence it is said in Proverbs (21:1): “The heart of the king is in the hand of the Lord; wherever He wishes, He turns it.” And again in Philippians (2:13): “It is God Who works in us, both to will and to accomplish, according to His good will.”
Chapter 89
THAT THE MOVEMENT OF THE WILL IS CAUSED BY GOD AND NOT ONLY THE POWER OF THE WILL
[1] Some people, as a matter of fact, not understanding how God could cause a movement of the will in us without prejudice to freedom of will, have tried to explain these textsin a wrong way. That is, they would say that God causes willing and accomplishing within us in the sense that He causes in us the power of willing, but not in such a way that He makes us will this or that. Thus does Origen, in his Principles, explain free choice, defending it against the texts above.
[2] So, it seems that there developed from this view the opinion of certain people who said that providence does not apply to things subject to free choice, that is, to acts of choice, but, instead, that providence is applied to external events. For he who chooses to attain or accomplish something, such as to make a building or to become rich, is not always able to reach this end; thus, the results of our actions are not subject to free choice, but are controlled by providence.
[3] To these people, of course, opposition is offered quite plainly by the texts from Sacred Scripture. For it is stated in Isaiah (26:2): “O Lord, Thou hast wrought all our works in us.” So, we receive not only the power of willing from God, but also the operation.
[4] Again, this statement of Solomon, “wherever He wishes, He turns it” shows that divine causality is not only extended to the power of the will but also to its act.
[5] Besides, God not only gives powers to things but, beyond that, no thing can act by its own power unless it acts through His power, as we showed above. So, man cannot use the power of will that has been given him except in so far as he acts through the power of God. Now, the being through whose power the agent acts is the cause not only of the power, but also of the act. This is apparent in the case of an artist through whose power an instrument works, even though it does not get its own form from this artist, but is merely applied to action by this man. Therefore, God is for us the cause not only of our will, but also of our act of willing.
[6] Moreover, a more perfect order is found in spiritual things than in corporeal ones. Among bodies, however, every motion is caused by the first motion. Therefore, among spiritual things, also, every movement of the will must be caused by the first will, which is the will of God.
[7] Furthermore, we showed somewhat earlier that God is the cause of every action and that He operates in every agent. Therefore, He is the cause of the movements of the will.
[8] Besides, an argument that is pertinent is offered by Aristotle, in Book VIII of the Eudemian Ethics, as follows. There must be a cause for the fact that a person understands, deliberates, chooses, and wills, for every new event must have some cause. But, if its cause is another act of deliberation, and another act of will preceding it, then, since one cannot go on to infinity in these acts, one must reach something that is first. Now, a first of this type must be something that is better than reason. But nothing is better than intellect and reason except God. Therefore, God is the first principle of our acts of counsel and of will.
Chapter 90
THAT HUMAN ACTS OF CHOICE AND OF WILL ARE SUBJECT TO DIVINE PROVIDENCE
[1] It is clear, next, that even acts of human willing and choosing must be subject to divine providence.
[2] For, everything that God does He does as a result of the order of His providence. So, since He is the cause of our act of choice and volition, our choices and will-acts are subject to divine providence.
[3] Again, all corporeal things are governed through spiritual beings, as we showed above.But spiritual beings act on corporeal things through the will. Therefore, if choices and movements of the wills of intellectual substances do not belong to God’s providence, it follows that even corporeal things are withdrawn from His providence. And thus, there will be no providence at all.
[4] Besides, the more noble things are in the universe, the more must they participate in the order in which the good of the universe consists. So, in Physics II [4], Aristotle accuses the ancient philosophers of putting chance and fortune in the make-up of the celestial bodies, but not in things below. Now, the intellectual substances are more noble than bodily substances. Therefore, if bodily substances, in their substances and actions, fall under the order of providence, so do intellectual substances, for a greater reason.
[5] Moreover, things that are nearer the end fall more definitely under the order which is for the end, for by their mediation other things also are ordered to the end. But the actions of intellectual substances are more closely ordered to God as end than are the actions of other things, as we showed above. So, the actions of intellectual substances, by which God orders all things to Himself, more definitely fall under the order of providence than the actions of other things.
[6] Furthermore, the governance of providence stems from the divine love whereby God loves the things created by Him; in fact, love consists especially in this, “that the lover wills the good for his loved one.” So, the more that God loves things, the more do they fall under His providence. Moreover, Sacred Scripture also teaches this in the Psalm (144:20) when it states: “The Lord keeps all those who love Him.” And the Philosopher, also, supports this view, in Ethics X [8], when he says that God takes greatest care of those who love understanding, as He does of His friends. It may, then, be gathered from this, that He loves intellectual substances best. Therefore, their acts of will and choice fall under His providence.
[7] Again, man’s internal goods, which are dependent on will and action, are more proper to man than things that are outside him, like the acquisition of wealth or anything else of that kind. Hence, man is deemed good by virtue of the former and not of the latter. So, if acts of human choice and movements of will do not fall under divine providence, but only their external results, it will be truer that human affairs are outside providence than that they come under providence. But this view is suggested by the words of blasphemers: “He walks about the poles of heaven, and He does not consider our things” (Job 22:14); and again: “The Lord has forsaken the earth, and the Lord does not see” (Ez. 9:9); and also: “Who is he who will command a thing to be done, when the Lord does not command it?” (Lam. 3:37).
[8] However, certain passages in Sacred Scripture appear to be consonant with the aforementioned view. It is said in fact (Sirach 15:14): “God made man from the beginning, and left him in the hand of his own counsel”; and later: “He has set water and fire before you; stretch forth your hand to whichever you wish. Before man is life and death, good and evil; that which he chooses shall be given him” (Sirach 15:14, 17-18). And also: “Consider that I have set before thee this day life and good, and on the other hand death and evil” (Deut. 30:15). But these words are brought forward to show that man is possessed of free choice, not that his choices are placed outside divine providence.
[9] Likewise, Gregory of Nyssa states in his book On Man: “Providence is concerned with the things that are not in our power, but not with those that are in our power”; and, following him, Damascene states in Book II, that “God foreknows the things that are within our power, but He does not predetermine them.” These texts should be explained as meaning that things in our power are not subject to determination by divine providence in the sense that they receive necessity from it.
Chapter 91
HOW HUMAN EVENTS MAY BE TRACED BACK TO HIGHER CAUSES
[1] From the things shown above we can gather how human actions may be traced back to higher causes and are not performed fortuitously.
[2] Of course, acts of choice and movements of the will are controlled immediately by God. And human intellectual knowledge is ordered by God through the mediation of the angels. Whereas matters pertinent to bodily things, whether they are internal or external, when they come within the use of man, are governed by God by means of the angels and the celestial bodies.
[3] Now, in general, there is one reason for this. Everything that is multiform, mutable, and capable of defect must be reducible to a source in something that is uniform, immutable, and capable of no defect. But all things that are within our power are found to be multiple, variable, and defectible.
[4] It is clear that our acts of choice have the character of multiplicity, since choices are made of different things, by different people, in different ways. They are also mutable, both because of the instability of the mind, which is not firmly fixed on the ultimate end, and also because of the fluctuating character of the things which provide our circumstantial environment. That they are defectible, of course the sins of men testify. But the divine will is uniform, because by willing one object it wills all else, and it is immutable and without defect, as we showed in Book One. So, the movement of all wills and choices must be traced back to the divine will, and not to any other cause, for God alone is the cause of our acts of will and choice.
[5] Likewise, our understanding has the quality of multiplicity, since we gather, as it were, intelligible truth from many sense objects. It is also mutable, for it advances by discursive movement from one thing to another, proceeding from known things to unknown ones. It is, moreover, defectible, because of the admixture of imagination with sensation, as the errors of mankind show. On the other hand, the cognitive acts of the angels are uniform: for they receive the knowledge of truth from one fount of truth; namely, God. Their cognition is also immutable, because they see directly the pure truth about things by a simple intuition, not by a discursive movement from effects to their causes or the reverse. It is even incapable of defect, since they directly intuit the very natures, or quiddities, of things, and understanding cannot err in regard to such objects, just as sense cannot err in regard to proper sensibles. We, however, make guesses as to the quiddities of things from their accidents and effects. Therefore, our intellectual knowledge must be regulated by means of the angelsknowledge.
[6] Again, in regard to human bodies and the external things that men use, it is obvious that there is in them a multiplicity of admixture and contrariety; and that they are not moved uniformly, since their motions cannot be continuous; and that they are defectible through alteration and corruption. In contrast, the celestial bodies are uniform in the way of simple beings with no contrariety in their constitution. Their motions are also uniform, continuous, and always in the same condition. Nor can there be corruption or alteration in them. Hence, it is necessary for our bodies, and the others which come under our use, to be regulated by means of the motions of the celestial bodies.
Chapter 92
HOW A PERSON IS FAVORED BY FORTUNE AND HOW MAN IS ASSISTED BY HIGHER CAUSES
[1] Next, we can show how a person might be said to be favored by fortune.
[2] In fact, we say that some good fortune has befallen a man “when something good happens to him, without his having intended it.” For example, a man digging in a field may find a treasure for which he was not looking. Now, something may happen to a certain agent which is not intended by him as he is doing his job, but which is not unintended by the superior under whom he is working. Suppose, for instance, a master orders a servant to go to a certain place to which the master has already sent another servant , unknown to the first one; the encounter with his fellow servant is not intended by the servant who has been sent, but it is not unintended by the master who sent him. And so, though the meeting is fortuitous and a matter of chance to this servant, it is not so to the master, but has been a planned event. So, since man is ordered in regard to his body under the celestial bodies, in regard to his intellect under the angels, and in regard to his will under God—it is quite possible for something apart from man’s intention to happen, which is, however, in accord with the ordering of the celestial bodies, or with the control of the angels, or even of God. For, though God alone directly works on the choice made by man, the action of an angel does have some effect on man’s choice by way of persuasion, and the action of a celestial body by way of disposition, in the sense that the corporeal impressions of celestial bodies on our bodies give a disposition to certain choices. So, when as a result of the influence of higher causes in the foregoing way a man is inclined toward certain choices that are beneficial to him, but whose benefit he does not know by his own reasoning, and when besides this his intellect is illuminated by the light of intellectual substances so that he may do these things, and when his will is inclined by divine working to choose something beneficial to him while he is ignorant of its nature, he is said to be favored by fortune. And, on the contrary, he is said to be subject to misfortune when his choice is inclined to contrary results by higher causes, as is said of a certain man: “Write this man barren, a man that shall not prosper in his days” (Jer. 22:30).
[3] But, on this point, a difference is to be noted. The impressions of celestial bodies on our bodies cause natural dispositions of our bodies within us. Thus, as a result of a disposition left by a celestial body in our body, a man is called not merely fortunate or unfortunate, but also wen or ill favored by nature, and it is in this way that the Philosopher says, in his Magna Moralia, that a man favored by fortune is also favored by nature. Indeed, this fact, that one man chooses things beneficial to him, whereas another man chooses things harmful to him, apart from their proper reasoning, cannot be understood as resulting from differences of intellectual nature, because the nature of intellect and will is one in all men. In fact, a formal diversity would lead to a difference according to species, whereas a material diversity leads to a numerical difference. Hence, in so far as man’s intellect is enlightened for the performance of some action, or as his will is prompted by God, the man is not said to be favored by birth, but, rather, well guarded or well governed.
[4] Again, another difference on this matter is to be observed. As a matter of fact, the operation of an angel and of a celestial body is merely like something disposing toward choice; while God’s operation is like something perfecting. Now, since a disposition which results from a quality of the body, or from an intellectual persuasion, does not bring necessity to the act of choice, a man does not always choose what his guardian angel intends, or that toward which a celestial body gives inclination. But a man does choose in all cases the object in accord with God’s operation within his will. Consequently, the guardianship of the angels is sometimes frustrated, according to this text: “We would have cured Babylon, but she is not healed” (Jer. 51:9); and still more is this true of the inclination of the celestial bodies, but divine providence is always steadfast.
[5] Moreover, there is still another difference to be considered. Since a celestial body does not dispose to a choice, unless it makes an impression on our body by which man is stimulated to choose in the way that passions induce one to choose, every disposition to choice which results from the celestial bodies works by means of some passion, as when a person is led to choose something by means of hatred, or love, or anger, or some similar passion. But a person is disposed to an act of choice by an angel, by means of an intellectual consideration, without passion. In fact, this happens in two ways. Sometimes, a man’s understanding is enlightened by an angel to know only that something is a good thing to be done, but it is not instructed as to the reason why it is a good, since this reason is derived from the end. Thus, at times, a man thinks that something is a good thing to be done, “but, if he be asked why, he would answer that he does not know. Hence, when he reaches a beneficial end, to which he has given no thought before, it will be fortuitous for him. But sometimes he is instructed by angelic illumination, both that this act is good and as to the reason why it is good, which depends on the end. And if this be so, when he reaches the end which he has thought about before, it will not be fortuitous. We should also note that, just as the active power of a spiritual nature is higher than a corporeal one, so also is it more universal. Consequently, the disposition resulting from a celestial body does not extend to all the objects which human choice covers.
[6] Still another point: the power of the human soul, or also of an angel, is particularized in comparison with divine power which, in fact, is universal in regard to all beings. Thus, then, some good thing may happen to a man which is apart from his own intention, and apart from the inclination given by celestial bodies, and apart from the enlightenment coming from the angels—but not apart from divine providence, which is regulative, just as it is productive, of being as such, and, consequently, which must include all things under it. Thus, some good or evil may happen to man that is fortuitous in relation to himself, and in relation to the celestial bodies, and in relation to the angels, but not in relation to God. Indeed, in relation to Him, nothing can be a matter of chance and unforeseen, either in the sphere of human affairs or in any matter.
[7] But, since fortuitous events are those apart from intention, and since moral goods cannot be apart from intention, because they are based on choice, in their case no one can be called well or ill favored by fortune. However, in regard to them, a person can be called well or ill favored by birth; when, as a result of the natural disposition of his body, he is prone to virtuous, or vicious, acts of choice. But in regard to external goods, which can accrue to a man apart from his intention, a man may be said to be both favored by birth and by fortune, and also governed by God and guarded by the angels.
[8] Moreover, man may obtain from higher causes still another help in regard to the outcome of his actions. For, since a man has both the ability to choose and to carry out what he chooses, he may at times be assisted by higher causes in regard to both or he may also be hindered. In regard to choice, of course, as we said, man is either disposed by the celestial bodies to choose something, or he is enlightened by the guardianship of the angels, or even he is inclined by divine operation. But in regard to the carrying out of the choice man may obtain from a higher cause the strength and efficacy needed to accomplish what he has chosen. Now, this can come not only from God and the angels, but also from the celestial bodies, to the extent that such efficacy is located in his body. For it is obvious that inanimate bodies also obtain certain powers and abilities from the celestial bodies, even beyond those which go along with the active and passive qualities of the elements, which, doubtless, are also subject to the celestial bodies. Thus, the fact that a magnet attracts iron is due to the power of a celestial body, and so have certain stones and herbs other hidden powers. So, nothing prevents a man, too, from getting, as a result of the influence of a celestial body, a certain special efficiency in doing some bodily actions, which another man does not possess: for instance, a physician in regard to healing, a farmer in regard to planting,’and a soldier in regard to fighting.
[9] Now, in a much more perfect way, God lavishes on man this special efficiency in the carrying out of His works efficaciously. So, in regard to the first kind of help, which applies to the act of choosing, God is said to direct man, whereas in regard to the second kind of help He is said to strengthen man. And these two forms of help are touched on together in the Psalms (26:1), where it is said in regard to the first: “The Lord is my light and my salvation, whom shall I fear?” and in regard to the second: “The Lord is the protector of my life, of whom shall I be afraid?”
[10] But there are two differences between these two helps. First, man is assisted by the first kind of help, both in regard to things subject to the power of man, and also in regard to other things. But the second sort of help extends only to things of which man’s power is capable. Indeed, the fact that a man digging a grave discovers a treasure results from no power of man; so, in regard to such an outcome, man may be helped by the fact that be is prompted to look in the place where the treasure is, not, however, in the sense that he is given any power to find treasure. But, in the case of the physician healing, or the soldier winning a fight, he may be helped in regard to the end, and also in the sense that he may carry out the choice efficaciously, by means of a power acquired from a higher cause. Hence, the first kind of help is more universal. The second difference is that the second help is given to carry out efficaciously what he intends. Consequently, since fortuitous events are apart from one’s intention, man cannot, properly speaking, be called fortunate as a result of such help, as he can be from the first, as we showed above.
[11] Now, it is possible for a man to be well or ill favored by fortune, in some cases, when he is the sole agent, as for instance, when he is digging in the earth, he finds a treasure lying there. In other cases, it may result from the action of another concurrent cause, as when the man going to market to buy something encounters a debtor whom he did not think he would find. Now, in the first case, the man is helped so that something good happens to him, only in the fact that he is directed to the choosing of an object to which something advantageous is attached, and this comes about apart from his intention. But in the second case, both agents must be directed to choose the action, or movement, which is the occasion for their meeting.
[12] We must consider another thing in regard to what was said above. For we said that, in order for something favorable or unfavorable to happen to a man on the basis of fortune, the help can come from God, and it can also come from a celestial body: in so far as a man is inclined by God to choose something with which there is combined an advantageous, or disadvantageous, result which the chooser has not thought of before, and in so far as he is disposed by a celestial body to choose such an object. Now, this advantage, or disadvantage, is fortuitous in regard to man’s choice; in regard to God, it loses the character of the fortuitous, but not in regard to the celestial body.
This becomes evident, as follows. In fact, an event does not lose its fortuitous character unless it may be referred back to a direct cause. But the power of a celestial body is an agent cause, not by way of understanding and choice, but as a nature. Now, it is proper for a nature to tend to one objective. So, if an effect is not simply one result, then its direct cause cannot be a natural power. But, when two things are combined with each other accidentally, they are not truly one, but only accidentally so. Hence, there can be no direct, natural cause for this union. Let us suppose, then, that a certain man is prompted to dig a grave by the influence of a celestial body, working by way of a passion as we said. Now, the grave and the location of the treasure are one only accidentally, for they have no relation to each other. Hence, the power of the celestial body cannot directly give an inclination toward this entire result: that this man should dig this grave and that it should be done at the place where the treasure is. But an agent working through understanding can be the cause of an inclination to this entire result, for it is proper to an intelligent being to order many things into one. It is clear, indeed, that even a man who knew where the treasure was might send another man who did not know to dig a grave in that same place and thus to find a treasure unintentionally. So, in this way, fortuitous events of this kind, when referred to their divine cause, lose their fortuitous character, but when referred to a celestial cause, they do not.
[13] It is also apparent by the same reasoning that a man cannot be universally favored by fortune through the power of a celestial body, but only in regard to this or that incident. I say universally, meaning that a man might have the ability in his nature, resulting from the influence of a celestial body, to choose always, or in most cases, objects to which certain advantages or disadvantages are accidentally connected. For nature is ordered to one result only. But these factors, in terms of which good or bad fortune befalls a man, are not reducible to any one thing; rather, they are indeterminate and indefinite, as the Philosopher teaches in Physics II, and as is clear to our senses. So, it is not possible for a man to have the ability in his nature to choose always those objects from which advantageous results accidentally follow. But it is possible that, by celestial influence, he may be inclined to choose one thing to which an advantage is accidentally attached; then, from another inclination to another advantage; and from a third to a third advantage; but not in such a way that all such advantages would follow from one inclination. However, from one divine disposition a man can be directed to all results.
Chapter 93
ON FATE: WHETHER AND WHAT IT IS
[1] It is evident from the points set forth above what view we should take regarding fate.
[2] Indeed, men observe that many things happen by accident in this world if their particular causes be considered, and some men have maintained that they are not even ordered by higher causes. To these people it has appeared that there is no fate at all.
[3] But others have attempted to reduce these events to certain higher causes from which they result in an orderly way, in accord with a definite plan. These people have asserted that there is fate in the sense that things observed to happen by chance are “pre-fated,” that is, foretold and pre-ordained to happen.
[4] Some of these people, then, have tried to reduce all contingent events which occur by chance, here below, to causes among the celestial bodies, and even human acts of choice to the controlling power of the stars; to which power all things are subject, they claimed, with a certain necessity which they called fate. Of course, this theory is impossible and foreign to the faith, as is clear from our preceding considerations.
[5] On the other hand, some men have desired to reduce to the control of divine providence all things whatsoever that appear to happen by chance in these lower beings. Hence, they said that all things are done by fate, meaning by fate the ordering which is found in things as a result of divine providence. Thus, Boethius says [De consol. phil. IV, 6]: “fate is a disposition inherent in mutable things, whereby providence connects each thing with His orders.” In this description of fate, “disposition” is used for ordering; while the phrase “inherent in things” is used to distinguish fate from providence; since the ordering, as present in the divine mind and not yet impressed on things, is providence, but, as already unfolded in things, it is called fate. Moreover, he speaks of “mutable things” to show that the order of providence does not take away contingency and mobility from things, as some men have claimed.
[6] So, according to this meaning, to deny fate is to deny providence. But, since we should not even have names in common with unbelievers, lest occasion for error could be taken from the association of names, the name fate is not to be used by the faithful lest we appear to agree with those who have held a wrong opinion about fate, by subjecting all things to the necessitation of the stars. Consequently, Augustine says, in Book V of the City of God: “If any man calls the will, or power, of God by the name, fate, let him hold his view, but correct his way of speaking.” And also Gregory, in accord with the same understanding of it, says: “Far be it from the minds of the faithful to say that there is any fate.”
Chapter 94
ON THE CERTAINTY OF DIVINE PROVIDENCE
[1] Now, there is a difficulty that arises out of the foregoing. If all things that are done here below, even contingent events, are subject to divine providence, then, seemingly, either providence cannot be certain or else all things happen by necessity.
[2] In fact, the Philosopher shows in the Metaphysics [V, 3] that, if we assert that every effect has a direct cause, and again that, given any direct cause we must necessarily grant its effect, it follows that all future events come about by necessity. For, if each effect has a direct cause, then any future effect will be reducible to a present or past cause. Thus, if we ask whether a certain man is to be killed by robbers, the cause preceding this effect is his encounter with the robbers; and, in turn, another cause precedes this effect, namely, the fact that he went out of his home; still another precedes this, that he wished to look for water; and a cause precedes this, namely, his thirst; and this was caused by the eating of salted foods; and this eating is going on now, or was done in the past. Therefore, if it be so, that, granted the cause, the effect must be granted, then necessarily, if he cats salt foods, he must get thirsty; and if he is thirsty, he must desire to get water; and if he desires to get water, he must go out of his home; and if he leaves his home, the robbers must encounter him; and if they encounter him, he must be killed. So, from the first to the last, it is necessary for this eater of salty foods to be killed by robbers. Therefore, the Philosopher concludes that it is not true that, granted the cause, the effect must be granted; since there are some causes which can fail. Again, it is not true that every effect has a direct cause, for something that comes about accidentally, for instance, that this man who wishes to look for water encounters the robbers, has no cause.
[3] Now, by this reasoning it appears that all effects that may be reduced to some direct cause, present or past, which when granted requires that the effect be granted must of necessity happen. Either, then, we must say that not all effects are subject to divine providence and, thus, that providence does not apply to all—but we showed earlier that it does; or else it is not necessarily so, that, granted providence, its effect must be granted, and thus providence is not certain; or, finally, it is necessary for all things to happen by necessity. For providence is not only in present or past time, but in eternity, since nothing can be in God that is not eternal.
[4] Again, if divine providence is certain, then this conditional proposition must be true: If God foresees this, then this will happen. Now, the antecedent of this conditional proposition is necessary, for He is eternal. Therefore, the consequent is necessary, for every consequent in a conditional proposition must be necessary when the antecedent is necessary. So, the consequent is like the conclusion of the antecedent, and whatever follows from a necessary proposition must be necessary. Therefore, it follows that, if divine providence is certain, all things must occur by necessity.
[5] Besides, suppose that something is foreseen by God; for example, that a certain man will become a ruler. Now, it is either possible that be will not rule, or it is not. But, if it is not possible that be will not rule, then it is impossible for him not to rule; therefore, it is necessary for him to rule. However, if it is possible that he will not rule, and if, given the possible something impossible does not follow, then it does follow that divine providence will fail; hence, it is not impossible for divine providence to fail. Therefore, it is either necessary, if all things are foreseen by God, that divine providence be not certain or else that all things happen by necessity.
[6] Moreover, Tully argues as follows, in his book On Divination [II, 7]: if all things are foreseen by God, the order of causes is certain. But, if this is true, all things are done by fate. And if all things are done by fate, nothing is within our power, there is no volitional choice. Therefore, it follows that free choice is taken away if divine providence be certain. And in the same way it will follow that all contingent causes are taken away.
[7] Furthermore, divine providence does not exclude intermediate causes, as we showed above, But, among causes, some are contingent and capable of failing. So, it is possible for an effect of providence to fail. Therefore, God’s providence is not certain.
[8] However, for the purpose of answering these arguments, we must repeat some of the observations put down before, so that it may be made clear that nothing escapes divine providence; also, that the order of divine providence cannot possibly be changed; and yet that it is not necessary for all things to happen of necessity simply because they come about as a result of divine providence.
[9] First, then, we must consider the fact that, since God is the cause of all existing things, giving being to all, the order of His providence must embrace all things. Indeed, on the things on which He has lavished being He must also lavish preservation and guide them toward perfection in their ultimate end.
[10] Now, two things must be considered in the case of any provident agent—namely, premeditation of the order, and the establishment of the premeditated order—in the things that are subject to providence. The first of these pertains to the cognitive power, while the second belongs to the operative. Between the two there is this difference: in the act of premeditating the order, the more perfect that providence is, the more can the order of providence be extended to the smallest details. The fact that we are not able to think out, ahead of time, the order of all particular events in regard to matters to be arranged by us stems from the deficiency of our knowledge, which cannot embrace all singular things. However, the more a person is able to think ahead about a plurality of singular things, the more adroit does he become in his foresight, while the man whose foresight is restricted to universals only participates but little in prudence. Now, a similar consideration can be made in regard to all the operative arts. But, in regard to imposing the premeditated order on things, the providence of a governing agent is more noble and perfect the more universal it is and the more it accomplished his premeditated plan by means of a plurality of ministers, because this controlling of ministers occupies an important place -in the order that pertains to foresight.
Moreover, divine providence must consist in the highest pe tion, since He is absolutely and universally perfect, as we showed in Book One. So, in the function of providential foresight, by means of the sempiternal meditative act of His wisdom, He orders all things, no matter how detailed they may appear; and whatever things perform any action, they act instrumentally, as moved by Him. And they obediently serve as His ministers in order to unfold in things the order of providence, which has been thought out, as I might say, from eternity. But, if all things able to act must serve as ministers to Him in their actions, it is impossible for any agent to block the execution of divine providence by acting in opposition to it. Nor is it possible for divine providence to be hindered by the defect of any agent or patient, since every active and passive power is caused in things in accord with divine disposition. It is also impossible for the execution of divine providence to be impeded by a change in the provident Agent, since God is altogether immutable, as we showed above. The conclusion remains, then, that divine foresight is utterly incapable of being frustrated.
[11] Next, we must consider that every agent intends the good and the better, in so far as he can, as we showed above. But the good and the better are not considered in the same way, in the whole and in the parts. For, in the whole, the good is integrity, which is the result of the order and composition of its parts. Consequently, it is better for there to be an inequality among the parts of the whole, without which the order and perfection of the whole cannot be, than for all its parts to be equal, even if each of them were to exist on the level of the most important part. However, if the parts are considered in themselves, each part of a lower grade would be better if it were on the level of the higher part. This is exemplified in the human body: in fact, the foot would be a more worthy part if it possessed the beauty and power of the eye, but the whole body would be more imperfect if it lacked the functioning of the foot.
Therefore, the intention of a particular agent tends toward a different objective from that of the universal agent. Indeed, the particular agent tends to the good of the part without qualification, and makes it the best that it can, but the universal agent tends to the good of the whole. As a result, a defect which is in accord with the intention of the universal agent may be apart from the intention of the particular agent. Thus, it is clear that the generation of a female is apart from the intention of a particular nature, that is, of the power which is in this semen which, as much as possible, tends to a perfect result of conception; but it is in accord with the intention of the universal nature, that is, of the power of the universal agent for the generation of inferior beings, that a female be generated; for without a female the generation of a number of animals could not be accomplished. Similarly, corruption, decrease, and every defect pertain to the intention of the universal nature, but not of the particular nature, for each thing avoids defect, and tends to perfection, to the extent that it can. So, it is evident that the intention of the particular agent is that its effect become as perfect as is possible in its kind, but the intention of the universal nature is that this individual effect become perfect in a certain type of perfection, say in male perfection, while another would become so in female perfection.
Now the primary perfection among the parts of the whole universe appears on the basis of the contingent and the necessary. For the higher beings are necessary and incorruptible and immobile, and the more they fall short of this condition, the lower the level on which they are established. Thus, the lowest things may be corrupted even in regard to their being, whereas they are changed in regard to their dispositions, and they produce their effects not necessarily but contingently. So, any agent that is a part of the universe intends as much as possible to persevere in its actual being and natural disposition, and to make its effect stable. However, God, Who is the governor of the universe, intends some of His effects to be established by way of necessity, and others contingently. On this basis, He adapts different causes to them; for one group of effects there are necessary causes, but for another, contingent causes. So, it falls under the order of divine providence not only that this effect is to be, but also that this effect is to be contingently, while another is to be necessarily. Because of this, some of the things that are subject to providence are necessary, whereas others are contingent and not at all necessary.
[17] So, it is obvious that, though divine providence is the direct cause of an individual future effect, and though it is so in the present, or in the past, indeed from eternity, it does not follow, as the first argument implies, that this individual effect will come about of necessity. For divine providence is the direct cause why this effect occurs contingently. And this cannot be prevented.
[13] From this it is also evident that this conditional proposition is true: If God foresees that this event will be, it will happen, just as the second argument suggested. But it will occur in the way that God foresaw that it would be. Now, He foresaw that it would occur contingently. So, it follows that, without fail, it will occur contingently and not necessarily.
[14] It is also clear that, if this thing which, we grant, is foreseen by God as to occur in the future belongs in the genus of contingent beings, it will be possible for it, considered in itself, not to be; for thus is it foreseen, as something that is contingent, as able not to be. Yet it is not possible for the order of providence to fail in regard to its coming into being contingently. Thus the third argument is answered. Consequently, it can be maintained that this man may not become a ruler if he be considered in himself, but not if he be considered as an object of divine foresight.
[15] Also, the objection that Tully offers seems frivolous, in view of the foregoing. Indeed, since not only effects are subject to divine providence, but also causes and ways of being, as is obvious from what we have asserted before, it does not follow that, if everything be done by divine providence, nothing is within our power. For the effects are foreseen by God, as they are freely produced by us.
[16] Nor can the possibility of failure on the part of secondary causes, by means of which the effects of providence are produced, take away the certainty of divine providence, as the fifth argument implied. For God Himself operates in all things, and in accord with the decision of His will, as we showed above. Hence, it is appropriate to His providence sometimes to permit defectible causes to fail, and at other times to preserve them from failure.
[17] Finally, those arguments in favor of the necessity of effects foreseen by God, which might be drawn from the certainty of knowledge, are solved above, where we treated of God’s knowledge.
Chapter 95
THAT THE IMMUTABILITY OF DIVINE PROVIDENCE DOES NOT SUPPRESS THE VALUE OF PRAYER
[1] We should also keep in mind the fact that, just as the immutability of providence does not impose necessity on things that are foreseen, so also it does not suppress the value of prayer. For prayer is not established for the purpose of changing the eternal disposition of providence, since this is impossible, but so that a person may obtain from God the object which he desires.
[2] Indeed, it is appropriate for God to consent to the holy desires of a rational creature, not in the sense that our desires may move the immutable God, but that He, in His goodness, takes steps to accomplish these desired effects in a fitting way. For, since all things naturally desire the good, as we proved above, and since it pertains to the supereminence of divine goodness to assign being, and well-being, to all in accord with a definite order, the result is that, in accord with His goodness, He fulfills the holy desires which are brought to completion by means of prayer.
[3] Again, it is proper for a mover to bring the object that is moved to its end; hence, a thing is moved toward its end, and attains its end, and finds rest in it, by means of the same nature. Now, every desire is a certain movement toward the good, and indeed it cannot be present in things unless it be from God, Who is good essentially and the source of goodness. In fact, every mover moves toward something like itself. So, it is proper for God, in accord with His goodness, to bring to a fitting conclusion the proper desires that are expressed by our prayers.
[4] Besides, the nearer certain things are to the mover, the more efficaciously do they follow the influence of the mover; for instance, things that are nearer to a fire become hotter from it. Now, intellectual substances are nearer to God than are inanimate natural substances. Therefore, the influence of divine motion is more efficacious on intellectual substances than on other natural substances. But natural bodies participate in divine motion to the extent that they receive from Him a natural appetite for the good, and even in the appetite for fulfillment which is realized when they attain their appropriate ends. Therefore, there is much more reason for intellectual substances attaining the fulfillment of their desires which are presented to God by prayer.
[5] Moreover, it pertains to the essential meaning of friendship for the lover to will the fulfillment of the desire of the beloved, because he wishes the good and the perfect for the beloved. This is the reason for the statement that “it is characteristic of friends that they will the same thing. Now, we showed above that God loves His creature, and the more that any one of them participates in His goodness which is the first and chief object of His love, the more does He love it. So, He wills the desires of a rational creature to be satisfied, for, compared to other creatures, it participates most perfectly in divine providence. But His will is perfective in regard to things; indeed, He is the cause of things through His will, as we showed above. Therefore, it is appropriate to divine providence for Him to fulfill the desires of a rational creature when they are presented to Him through prayer.
[6] Furthermore, a creature’s good is transmitted by the divine goodness in accord with a certain likeness. But this characteristic seems most approvable among men: that they should not refuse consent to those who ask for favors in a just manner. Because of this, men are called liberal, clement, merciful, and upright. Therefore, this characteristic, of granting upright prayers, especially belongs to divine goodness.
[7] Hence, it is said in the Psalm (144:19): “He will do the will of those who fear Him, and He will hear their prayers and save them”; and again the Lord says: “Everyone who asks receives, and he who seeks finds, and to him who knocks it shall be opened” (Mat. 7:8).
Chapter 96
THAT SOME PRAYERS ARE NOT GRANTED BY GOD
[1] Now, it is not inappropriate if also, at times, the requests of some who pray are not granted by God.
[2] For we showed by reasoning that God fulfills the desires of a rational creature, to the extent that he desires the good. Now, it sometimes happens that what is sought in prayer is not a true, but an apparent, good; speaking absolutely, it is an evil. Therefore, such a prayer is not capable of being granted by God. Hence, it is said in James (4:3): “You ask and you receive not, because you ask amiss.”
[3] Likewise, because God moves us to the act of desiring, we showed that it is appropriate for Him to fulfill our desires. Now, the thing that is moved is not brought to its end by the mover unless the motion be continued. So, if the movement of desire is not continued by constant prayer, it is not inappropriate for the prayer to fail to receive its expected result. Hence, the Lord says in Luke (18:1) “that we ought always to pray and not to faint”; also, the Apostle says, in 1 Thessalonians (5:17): “Pray without ceasing.”
[4] Again, we showed that God fulfills in a suitable way the desire of a rational creature, depending on its nearness to Him. But one becomes near to Him through contemplation, devout affection, and humble but firm intention. So, the prayer which does not approach God in this way is not capable of being heard by God. Hence, it is said in the Psalm (101:18): “He has had regard to the prayer of the humble”; and in James (1:6): “Let him ask in faith, nothing wavering.”
[5] Besides, we showed that on the basis of friendship God grants the wishes of those who are holy. Therefore, he who turns away from God’s friendship is not worthy of having his prayer granted. Hence, it is said in Proverbs (28:9): “He who turns away his ears from hearing the law, his prayer shall be an abomination.” And again in Isaiah (1:15): “When you multiply prayer, I will not hear, for your hands are full of blood.”
[6] For the same reason it happens sometimes that a friend of God is not beard when he prays for those who are not God’s friends, according to the passage in Jeremiah (7:16): “Therefore, do not You pray for this people, nor take to You praise and supplication for them, and do not withstand me: for I will not hear You.”
[7] However, it happens at times that a person is refused because of friendship a petition which he asks of a friend, since he knows that it is harmful to him, or that the opposite is more helpful to him. Thus, a physician may deny sometimes the request of a sick person, having in mind that it is not beneficial to him in the recovery of his health. Consequently, since we showed that God, because of the love which He has for the rational creature, satisfies his desires when they are presented to Him through prayer, it is no cause for astonishment if at times He does not grant the petition, even of those whom He especially loves, in order to provide something that is more helpful for the salvation of the petitioner. For this reason, He did not withdraw the sting of the flesh from Paul, though he asked it thrice, for God foresaw that it was helpful to him for the preservation of humility, as is related in 2 Corinthians (12:7-9). Hence, the Lord says to certain people, in Matthew (20:22): “You do not know what you ask”; and it is said in Romans (8:26): “For we do not know what we should pray for as we ought.” For this reason, Augustine says in his letter to Paulinus and Therasia: “The Lord is good, for He often does not grant what we desire, so that He may give us what we desire even more.”
[8] It is apparent, then, from the foregoing that the cause of some things that are done by God is prayers and holy desires. But we showed above that divine providence does not exclude other causes; rather, it orders them so that the order which providence has determined within itself may be imposed on things. And thus, secondary causes are not incompatible with providence; instead, they carry out the effect of providence. In this way, then, prayers are efficacious before God, yet they do not destroy the immutable order of divine providence, because this individual request that is granted to a certain petitioner falls under the order of divine providence. So, it is the same thing to say that we should not pray in order to obtain something from God, because the order of His providence is immutable, as to say that we should not walk in order to get to a place, or eat in order to be nourished; all of which are clearly absurd.
[9] So, a double error concerning prayer is set aside as a result of the foregoing. Some people have said that prayer is not fruitful. In fact, this has been stated both by those who denied divine providence altogether, like the Epicueans, and by those who set human affairs apart from divine providence, as some Peripatetics do, and also by those who thought that all things subject to providence occur of necessity, as the Stoics did. From all these views, it follows that prayer is fruitless and, consequently, that all worship of the Deity is offered in vain. Indeed, this error is mentioned in Malachi (3:14), where it states: “You have said: He labors in vain who serves God. And what profit is it that we have kept His ordinances, and that we have walked sorrowful before the Lord of hosts?”
[10] Contrariwise, others have in fact said that the divine disposition is capable of being changed by prayers; thus, the Egyptians said that fate was subject to change by prayers and by means of certain idols, incensings, or incantations.
[11] Indeed, certain statements in the divine Scriptures seem, according to their superficial appearance, to favor this view. For it is said that Isaiah, at the command of the Lord, said to King Hezekiah: “Thus says the Lord: Take order with Your house, for You shall die, and shall not live”; and that, after the prayer of Hezekiah, “the word of the Lord came to Isaiah, saying: Go and say to Hezekiah... I have heard Your prayer... behold I will add to Your days fifteen years” (Is. 38:1-5). And again, it is said in the name of the Lord: “I will suddenly speak against a nation and against a kingdom to root out and to pull down and to destroy it. If that nation against which I have spoken shall repent of their evil, I will also repent of the evil that I have thought to do to them” (Jer. 18:7-8). And in Joel (2:13-14): “Turn to the Lord your God, for He is gracious and merciful... Who knows whether God will return and forgive?”
[12] Now, these texts, if understood superficially, lead to an unsuitable conclusion. For it follows, first of all, that God’s will is mutable; also, that something accrues to God in the course of time; and further, that certain things that occur in time to creatures are the cause of something occurring in God. Obviously, these things are impossible, as is evident from earlier explanations.
[13] They are opposed, too, by texts of Sacred Scripture which contain the infallible truth clearly expressed. Indeed, it is said in Numbers (23:19): “God is not as a man that He should lie, nor as the son of man that He should be changed. Did He say then, and will not do it? Has he spoken, and will He not fulfill?” And in 1 Sam (15:29): “The triumpher in Israel will not spare, and will not be moved to repentance; for He is not a man that He should repent.” And in Malachi (3:6): “I am the Lord and I do not change.”
[14] Now, if a person carefully considers these statements, he will find that every error that occurs on these points arises from the fact that thought is not given to the difference between universal and particular order. For, since all effects are mutually ordered, in the sense that they come together in one cause, it must be that, the more universal the cause is, the more general is the order. Hence, the order stemming from the universal cause which is God must embrace all things. So, nothing prevents some particular order from being changed, either by prayer, or by some other means, for there is something outside that order which could change it. For this reason, it is not astonishing for the Egyptians who reduce the order of human affairs to the celestial bodies, to claim that fate, which depends on the stars, can be changed by certain prayers and ceremonies. Indeed, apart from the celestial bodies and above them is God, Who is able to impede the celestial bodieseffect which was supposed to follow in things here below as a result of their influence.
But, outside the order that embraces all things, it is not possible for anything to be indicated by means of which the order depending on a universal cause might be changed. That is why the Stoics, who considered the reduction of the order of things to God to be to a universal cause of all things, claimed that the order established by God could not be changed for any reason. But, again on this point, they departed from the consideration of a universal order, because they claimed that prayers were of no use, as if they thought that the wills of men and their desires, from which prayers arise, are not included under that universal order. For, when they say that, whether prayers are offered or not, in any case the same effect in things follows from the universal order of things, they clearly isolate from that universal order the wishes of those who pray. For, if these prayers be included under that order, then certain effects will result by divine ordination by means of these prayers, just as they do by means of other causes. So, it will be the same thing to exclude the effect of prayer as to exclude the effect of all other causes. Because, if the immutability of the divine order does not take away their effects from other causes, neither does it remove the efficacy of prayers. Therefore, prayers retain their power; not that they can change the order of eternal control, but rather as they themselves exist under such order.
[15] But nothing prevents some particular order, due to an inferior cause, from being changed through the efficacy of prayers, under the operation of God Who transcends all causes, and thus is not confined under the necessity of any order of cause; on the contrary, all the necessity of the order of an inferior cause is confined under Him as being brought into being by Him. So, in so far as something in the order of inferior causes established by God is changed through prayer, God is said to turn or to repent; not in the sense that His eternal disposition is changed, but that some effect of His is changed. Hence, Gregory says that “God does not change His plan, though at times He may change His judgment”; not, I say, the judgment which expresses His eternal disposition, but the judgment which expresses the order of inferior causes, in accord with which Hezekiah was to have died, or a certain people were to have been punished for their sins. Now, such a change of judgment is called God’s repentance, using a metaphorical way of speaking, in the sense that God is disposed like one who repents, for whom it is proper to change what he had been doing. In the same way, He is also said, metaphorically, to become angry, in the sense that, by punishing, He produces the same effect as an angry person.
Chapter 97
HOW THE DISPOSITION OF PROVIDENCE HAS A RATIONAL PLAN
[1] From the points set forth above it may be seen clearly that the things which are disposed by divine providence follow a rational plan.
[2] Indeed, we showed that God, through His providence, orders all things to the divine goodness, as to an end;not, of course, in such a way that something adds to His goodness by means of things that are made, but, rather, that the likeness of His goodness, as much as possible, is impressed on things. However, since every created substance must fall short of the perfection of divine goodness, in order that the likeness of divine goodness might be more perfectly communicated to things, it was necessary for there to be a diversity of things, so that what could not be perfectly represented by one thing might be, in more perfect fashion, represented by a variety of things in different ways. For instance, when a man sees that his mental conception cannot be expressed adequately by one spoken word, he multiplies his words in various ways, to express his mental conception through a variety of means. And the eminence of divine perfection may be observed in this fact, that perfect goodness which is present in God in a unified and simple manner cannot be in creatures except in a diversified manner and through a plurality of things. Now, things are differentiated by their possession of different forms from which they receive their species. And thus, the reason for the diversity of forms in things is derived from this end.
[3] Moreover, the reason for the order of things is derived from the diversity of forms. Indeed, since it is in accord with its form that a thing has being, and since anything, in so far as it has being, approaches the likeness of God Who is His own simple being, it must be that form is nothing else than a divine likeness that is participated in things. Hence, Aristotle, where he speaks about form in Physics I [9], quite appropriately says that it is “something godlike and desirable.” But a likeness that is viewed in relation to one simple thing cannot be diversified unless by virtue of the likeness being more or less close or remote. Now, the nearer a thing comes to divine likeness, the more perfect it is. Consequently, there cannot be a difference among forms unless because one thing exists more perfectly than another. That is why Aristotle, in Metaphysics VIII [3], likens definitions, through which the natures of things and forms are signified, to numbers, in which species are varied by the addition or subtraction of unity; so, from this, we are made to understand that the diversity of forms requires different grades of perfection.
This is quite clear to one who observes the natures of things. He will find, in fact, if he makes a careful consideration, that the diversity of things is accomplished by means of gradations. Indeed, he will find plants above inanimate bodies, and above plants irrational animals, and above these intellectual substances. And among individuals of these types he will find a diversity based on the fact that some are more perfect than others, inasmuch as the highest members of a lower genus seem quite close to the next higher genus; and the converse is also true; thus, immovable animals are like plants. Consequently, Dionysius says [De div. nom. VII, 3] “Divine wisdom draws together the last members of things in a first class, with the first members of things in a second class.” Hence, it is apparent that the diversity of things requires that not all be equal, but that there be an order and gradation among things.
[4] Now, from the diversity of forms by which the species of things are differentiated there also results a difference of operations. For, since everything acts in so far as it is actual (because things that are potential are found by that very fact to be devoid of action), and since every being is actual through form, it is necessary for the operation of a thing to follow its form. Therefore, if there are different forms, they must have different operations.
[5] But, since each thing attains its proper end through its own action, various proper ends must be distinguished in things, even though the ultimate end is common to all.
[6] From the diversity of forms there also follows a diverse relationship of matter to things. In fact, since forms differ because some are more perfect than others, there are some of them so perfect that they are self-subsistent and self-complete, requiring no sub-structure of matter. But other forms cannot perfectly subsist by themselves, and do require matter as a foundation, so that what does subsist is not simply form, nor yet merely matter, but a thing composed of both.
[7] Now, matter and form could not combine to make up one thing unless there were some proportion between them. But, if they must be proportionally related, then different matters must correspond to different forms. Hence, it develops that some forms need simple matter, while others need composite matter; and also, depending on the various forms, there must be a different composition of parts, adapted to the species of the form and to its operation.
[8] Moreover, as a result of the diversified relationship to matter, there follows a diversity of agents and patients. For, since each thing acts by reason of its form, but suffers passion and is moved by reason of its matter, those things whose forms are more perfect and less material must act on those that are more material and whose forms are more imperfect.
[9] Again, from the diversity of forms and matters and agents there follows a diversity of properties and accidents. Indeed, since substance is the cause of accident, as the perfect is of the imperfect, different proper accidents must result from different substantial principles. In turn, since from different agents there result different impressions on the patients, there must be, depending on the different agents, different accidents that are impressed by agents.
[10] So, it is evident from what we have said that, when various accidents, actions, passions, and arrangements are allotted things by divine providence, this distribution does not come about without a rational plan. Hence, Sacred Scripture ascribes the production and governance of things to divine wisdom and prudence. Indeed, it is stated in Proverbs (3:19-20): “The Lord by wisdom bath founded the earth; He has established the heavens by prudence. By His wisdom the depths have broken out, and the clouds grow thick with dew.” And in Wisdom (8:1) it is said of the wisdom of God that “it reaches from end to end mightily, and orders all things sweetly.” Again, it is said in the same book: “You have ordered all things in measure, and number, and weight” (Wis. 11:21). Thus, we I may understand by measure: the amount, or the mode, or degree, of perfection pertaining to each thing; but by number: the plurality and diversity of species resulting from the different degrees of perfection; and by weight: the different inclinations to proper ends and operations, and also the agents, patients, and accidents which result from the distinction of species.
[11] Now, in the aforesaid order, in which the rational Plan of divine providence is observed, we have said that first place is occupied by divine goodness as the ultimate end, which is the first principle in matters of action. Next comes the numerical plurality of things, for the constitution of which there must be different degrees in forms and matters, and in agents and patients, and in actions and accidents. Therefore, just as the first rational principle of divine providence is simply the divine goodness, so the first rational principle in creatures is their numerical plurality, to the establishment and conservation of which all other things seem to be ordered. Thus, on this basis it seems to have been reasonably stated by Boethius, at the beginning of his Arithmetic, that: “All things whatever that have been established, at the original coming into being of things, seem to have been formed in dependence on the rational character of numbers.
[12] Moreover, we should consider the fact that operative and speculative reason partly agree and partly disagree. They agree, indeed, on this point: just as speculative reason starts from some principle and proceeds through intermediaries to the intended conclusion, so does operative reason start from something that is first, and go through certain intermediaries to the operation, or to the product of the operation, which is intended. But the principle in speculative matters is the form and that which is; while in operative matters it is the end, which at times is the form, at other times something else. Also, the principle in speculative matters must always be necessary, but in operative matters it is sometimes necessary and sometimes not. Indeed, it is necessary for a man to will felicity as his end, but it is not necessary to will to build a house. Likewise, in matters of demonstration the posterior propositions always follow of necessity from the prior ones, but it is not always so in operative reasoning; rather, it is only so when there can be only this single way of reaching the end. For instance, it is necessary for a man who wishes to build a house to get some lumber, but the fact that he tries to get lumber made of fir depends solely on his own will, and not at all on the reason for building the house.
[13] And so, the fact that God loves His goodness is necessary, but the fact that it is represented by means of creatures is not necessary, because divine
