On the contrary,"No one is moved to that which he cannot possibly reach" (De Coelo i, 7). But it is impossible to pass through the infinite. If therefore the inquiry of counsel is infinite, no one would begin to take counsel. Which is clearly untrue.
I answer that,The inquiry of counsel is actually finite on both sides, on that of its principle and on that of its term. For a twofold principle is available in the inquiry of counsel. One is proper to it, and belongs to the very genus of things pertaining to operation: this is the end which is not the matter of counsel, but is taken for granted as its principle, as stated above (A. 2). The other principle is taken from another genus, so to speak; thus in demonstrative sciences one science postulates certain things from another, without inquiring into them. Now these principles which are taken for granted in the inquiry of counsel are any facts received through the senses—for instance, that this is bread or iron: and also any general statements known either through speculative or through practical science; for instance, that adultery is forbidden by God, or that man cannot live without suitable nourishment. Of such things counsel makes no inquiry. But the term of inquiry is that which we are able to do at once. For just as the end is considered in the light of a principle, so the means are considered in the light of a conclusion. Wherefore that which presents itself as to be done first, holds the position of an ultimate conclusion whereat the inquiry comes to an end. Nothing however prevents counsel from being infinite potentially, for as much as an infinite number of things may present themselves to be inquired into by means of counsel.
Reply Obj. 1: Singulars are infinite; not actually, but only potentially.
Reply Obj. 2: Although human action can be hindered, the hindrance is not always at hand. Consequently it is not always necessary to take counsel about removing the obstacle.
Reply Obj. 3: In contingent singulars, something may be taken for certain, not simply, indeed, but for the time being, and as far as it concerns the work to be done. Thus that Socrates is sitting is not a necessary statement; but that he is sitting, as long as he continues to sit, is necessary; and this can be taken for a certain fact. ________________________
OF CONSENT, WHICH IS AN ACT OF THE WILL IN REGARD TO THE MEANS(In Four Articles)
We must now consider consent; concerning which there are four points of inquiry:
(1) Whether consent is an act of the appetitive or of the apprehensive power?
(2) Whether it is to be found in irrational animals?
(3) Whether it is directed to the end or to the means?
(4) Whether consent to an act belongs to the higher part of the soul only? ________________________
FIRST ARTICLE [I-II, Q. 15, Art. 1]
Whether Consent Is an Act of the Appetitive or of the ApprehensivePower?
Objection 1: It would seem that consent belongs only to the apprehensive part of the soul. For Augustine (De Trin. xii, 12) ascribes consent to the higher reason. But the reason is an apprehensive power. Therefore consent belongs to an apprehensive power.
Obj. 2: Further, consent is "co-sense." But sense is an apprehensive power. Therefore consent is the act of an apprehensive power.
Obj. 3: Further, just as assent is an application of the intellect to something, so is consent. But assent belongs to the intellect, which is an apprehensive power. Therefore consent also belongs to an apprehensive power.
On the contrary,Damascene says (De Fide Orth. ii, 22) that "if a man judge without affection for that of which he judges, there is no sentence," i.e. consent. But affection belongs to the appetitive power. Therefore consent does also.
I answer that,Consent implies application of sense to something. Now it is proper to sense to take cognizance of things present; for the imagination apprehends the similitude of corporeal things, even in the absence of the things of which they bear the likeness; while the intellect apprehends universal ideas, which it can apprehend indifferently, whether the singulars be present or absent. And since the act of an appetitive power is a kind of inclination to the thing itself, the application of the appetitive power to the thing, in so far as it cleaves to it, gets by a kind of similitude, the name of sense, since, as it were, it acquires direct knowledge of the thing to which it cleaves, in so far as it takes complacency in it. Hence it is written (Wis. 1:1): "Think of (Sentite) the Lord in goodness." And on these grounds consent is an act of the appetitive power.
Reply Obj. 1: As stated inDe Animaiii, 9, "the will is in the reason." Hence, when Augustine ascribes consent to the reason, he takes reason as including the will.
Reply Obj. 2: Sense, properly speaking, belongs to the apprehensive faculty; but by way of similitude, in so far as it implies seeking acquaintance, it belongs to the appetitive power, as stated above.
Reply Obj. 3:Assentire(to assent) is, to speak,ad aliud sentire(to feel towards something); and thus it implies a certain distance from that to which assent is given. Butconsentire(to consent) is "to feel with," and this implies a certain union to the object of consent. Hence the will, to which it belongs to tend to the thing itself, is more properly said to consent: whereas the intellect, whose act does not consist in a movement towards the thing, but rather the reverse, as we have stated in the First Part (Q. 16, A. 1; Q. 27, A. 4; Q. 59, A. 2), is more properly said to assent: although one word is wont to be used for the other [*In Latin rather than in English.]. We may also say that the intellect assents, in so far as it is moved by the will. ________________________
SECOND ARTICLE [I-II, Q. 15, Art. 2]
Whether Consent Is to Be Found in Irrational Animals?
Objection 1: It would seem that consent is to be found in irrational animals. For consent implies a determination of the appetite to one thing. But the appetite of irrational animals is determinate to one thing. Therefore consent is to be found in irrational animals.
Obj. 2: Further, if you remove what is first, you remove what follows. But consent precedes the accomplished act. If therefore there were no consent in irrational animals, there would be no act accomplished; which is clearly false.
Obj. 3: Further, men are sometimes said to consent to do something, through some passion; desire, for instance, or anger. But irrational animals act through passion. Therefore they consent.
On the contrary,Damascene says (De Fide Orth. ii, 22) that "after judging, man approves and embraces the judgment of his counselling, and this is called the sentence," i.e. consent. But counsel is not in irrational animals. Therefore neither is consent.
I answer that,Consent, properly speaking, is not in irrational animals. The reason of this is that consent implies an application of the appetitive movement to something as to be done. Now to apply the appetitive movement to the doing of something, belongs to the subject in whose power it is to move the appetite: thus to touch a stone is an action suitable to a stick, but to apply the stick so that it touch the stone, belongs to one who has the power of moving the stick. But irrational animals have not the command of the appetitive movement; for this is in them through natural instinct. Hence in the irrational animal, there is indeed the movement of the appetite, but it does not apply that movement to some particular thing. And hence it is that the irrational animal is not properly said to consent: this is proper to the rational nature, which has the command of the appetitive movement, and is able to apply or not to apply it to this or that thing.
Reply Obj. 1: In irrational animals the determination of the appetite to a particular thing is merely passive: whereas consent implies a determination of the appetite, which is active rather than merely passive.
Reply Obj. 2: If the first be removed, then what follows is removed, provided that, properly speaking, it follow from that only. But if something can follow from several things, it is not removed by the fact that one of them is removed; thus if hardening is the effect of heat and of cold (since bricks are hardened by the fire, and frozen water is hardened by the cold), then by removing heat it does not follow that there is no hardening. Now the accomplishment of an act follows not only from consent, but also from the impulse of the appetite, such as is found in irrational animals.
Reply Obj. 3: The man who acts through passion is able not to follow the passion: whereas irrational animals have not that power. Hence the comparison fails. ________________________
THIRD ARTICLE [I-II, Q. 15, Art. 3]
Whether Consent Is Directed to the End or to the Means?
Objection 1: It would seem that consent is directed to the end.Because that on account of which a thing is such is still more such.But it is on account of the end that we consent to the means.Therefore, still more do we consent to the end.
Obj. 2: Further, the act of the intemperate man is his end, just as the act of the virtuous man is his end. But the intemperate man consents to his own act. Therefore consent can be directed to the end.
Obj. 3: Further, desire of the means is choice, as stated above (Q. 13, A. 1). If therefore consent were only directed to the means it would nowise differ from choice. And this is proved to be false by the authority of Damascene who says (De Fide Orth. ii, 22) that "after the approval" which he calls "the sentence," "comes the choice." Therefore consent is not only directed to the means.
On the contrary,Damascene says (De Fide Orth. ii, 22) that the "sentence," i.e. the consent, takes place "when a man approves and embraces the judgment of his counsel." But counsel is only about the means. Therefore the same applies to consent.
I answer that,Consent is the application of the appetitive movement to something that is already in the power of him who causes the application. Now the order of action is this: First there is the apprehension of the end; then the desire of the end; then the counsel about the means; then the desire of the means. Now the appetite tends to the last end naturally: wherefore the application of the appetitive movement to the apprehended end has not the nature of consent, but of simple volition. But as to those things which come under consideration after the last end, in so far as they are directed to the end, they come under counsel: and so counsel can be applied to them, in so far as the appetitive movement is applied to the judgment resulting from counsel. But the appetitive movement to the end is not applied to counsel: rather is counsel applied to it, because counsel presupposes the desire of the end. On the other hand, the desire of the means presupposes the decision of counsel. And therefore the application of the appetitive movement to counsel's decision is consent, properly speaking. Consequently, since counsel is only about the means, consent, properly speaking, is of nothing else but the means.
Reply Obj. 1: Just as the knowledge of conclusions through the principles is science, whereas the knowledge of the principles is not science, but something higher, namely, understanding; so do we consent to the means on account of the end, in respect of which our act is not consent but something greater, namely, volition.
Reply Obj. 2: Delight in his act, rather than the act itself, is the end of the intemperate man, and for sake of this delight he consents to that act.
Reply Obj. 3: Choice includes something that consent has not, namely, a certain relation to something to which something else is preferred: and therefore after consent there still remains a choice. For it may happen that by aid of counsel several means have been found conducive to the end, and through each of these meeting with approval, consent has been given to each: but after approving of many, we have given our preference to one by choosing it. But if only one meets with approval, then consent and choice do not differ in reality, but only in our way of looking at them; so that we call it consent, according as we approve of doing that thing; but choice according as we prefer it to those that do not meet with our approval. ________________________
FOURTH ARTICLE [I-II, Q. 15, Art. 4]
Whether Consent to the Act Belongs Only to the Higher Part of theSoul?
Objection 1: It would seem that consent to the act does not always belong to the higher reason. For "delight follows action, and perfects it, just as beauty perfects youth" [*oion tois akmaiois he hora—as youthful vigor perfects a man in his prime] (Ethic. x, 4). But consent to delight belongs to the lower reason, as Augustine says (De Trin. xii, 12). Therefore consent to the act does not belong only to the higher reason.
Obj. 2: Further, an act to which we consent is said to be voluntary. But it belongs to many powers to produce voluntary acts. Therefore the higher reason is not alone in consenting to the act.
Obj. 3: Further, "the higher reason is that which is intent on the contemplation and consultation of things eternal," as Augustine says (De Trin. xii, 7). But man often consents to an act not for eternal, but for temporal reasons, or even on account of some passion of the soul. Therefore consent to an act does not belong to the higher reason alone.
On the contrary,Augustine says (De Trin. xii, 12): "It is impossible for man to make up his mind to commit a sin, unless that mental faculty which has the sovereign power of urging his members to, or restraining them from, act, yield to the evil deed and become its slave."
I answer that,The final decision belongs to him who holds the highest place, and to whom it belongs to judge of the others; for as long as judgment about some matter remains to be pronounced, the final decision has not been given. Now it is evident that it belongs to the higher reason to judge of all: since it is by the reason that we judge of sensible things; and of things pertaining to human principles we judge according to Divine principles, which is the function of the higher reason. Wherefore as long as a man is uncertain whether he resists or not, according to Divine principles, no judgment of the reason can be considered in the light of a final decision. Now the final decision of what is to be done is consent to the act. Therefore consent to the act belongs to the higher reason; but in that sense in which the reason includes the will, as stated above (A. 1, ad 1).
Reply Obj. 1: Consent to delight in the work done belongs to the higher reason, as also does consent to the work; but consent to delight in thought belongs to the lower reason, just as to the lower reason it belongs to think. Nevertheless the higher reason exercises judgment on the fact of thinking or not thinking, considered as an action; and in like manner on the delight that results. But in so far as the act of thinking is considered as ordained to a further act, it belongs to the lower reason. For that which is ordained to something else, belongs to a lower art or power than does the end to which it is ordained: hence the art which is concerned with the end is called the master or principal art.
Reply Obj. 2: Since actions are called voluntary from the fact that we consent to them, it does not follow that consent is an act of each power, but of the will which is in the reason, as stated above (A. 1, ad 1), and from which the voluntary act is named.
Reply Obj. 3: The higher reason is said to consent not only because it always moves to act, according to the eternal reasons; but also because it fails to dissent according to those same reasons. ________________________
OF USE, WHICH IS AN ACT OF THE WILL IN REGARD TO THE MEANS(In Four Articles)
We must now consider use; concerning which there are four points of inquiry:
(1) Whether use is an act of the will?
(2) Whether it is to be found in irrational animals?
(3) Whether it regards the means only, or the end also?
(4) Of the relation of use to choice. ________________________
FIRST ARTICLE [I-II, Q. 16, Art. 1]
Whether Use Is an Act of the Will?
Objection 1: It would seem that use is not an act of the will. For Augustine says (De Doctr. Christ. i, 4) that "to use is to refer that which is the object of use to the obtaining of something else." But "to refer" something to another is an act of the reason to which it belongs to compare and to direct. Therefore use is an act of the reason and not of the will.
Obj. 2: Further, Damascene says (De Fide Orth. ii, 22) that man "goes forward to the operation, and this is called impulse; then he makes use (of the powers) and this is called use." But operation belongs to the executive power; and the act of the will does not follow the act of the executive power, on the contrary execution comes last. Therefore use is not an act of the will.
Obj. 3: Further, Augustine says (QQ. 83, qu. 30): "All things that were made were made for man's use, because reason with which man is endowed uses all things by its judgment of them." But judgment of things created by God belongs to the speculative reason; which seems to be altogether distinct from the will, which is the principle of human acts. Therefore use is not an act of the will.
On the contrary,Augustine says (De Trin. x, 11): "To use is to apply to something to purpose of the will."
I answer that,The use of a thing implies the application of that thing to an operation: hence the operation to which we apply a thing is called its use; thus the use of a horse is to ride, and the use of a stick is to strike. Now we apply to an operation not only the interior principles of action, viz. the powers of the soul or the members of the body; as the intellect, to understand; and the eye, to see; but also external things, as a stick, to strike. But it is evident that we do not apply external things to an operation save through the interior principles which are either the powers of the soul, or the habits of those powers, or the organs which are parts of the body. Now it has been shown above (Q. 9, A. 1) that it is the will which moves the soul's powers to their acts, and this is to apply them to operation. Hence it is evident that first and principally use belongs to the will as first mover; to the reason, as directing; and to the other powers as executing the operation, which powers are compared to the will which applies them to act, as the instruments are compared to the principal agent. Now action is properly ascribed, not to the instrument, but to the principal agent, as building is ascribed to the builder, not to his tools. Hence it is evident that use is, properly speaking, an act of the will.
Reply Obj. 1: Reason does indeed refer one thing to another; but the will tends to that which is referred by the reason to something else. And in this sense to use is to refer one thing to another.
Reply Obj. 2: Damascene is speaking of use in so far as it belongs to the executive powers.
Reply Obj. 3: Even the speculative reason is applied by the will to the act of understanding or judging. Consequently the speculative reason is said to use, in so far as it is moved by the will, in the same way as the other powers. ________________________
SECOND ARTICLE [I-II, Q. 16, Art. 2]
Whether Use Is to Be Found in Irrational Animals?
Objection 1: It would seem that use is to be found in irrational animals. For it is better to enjoy than to use, because, as Augustine says (De Trin. x, 10): "We use things by referring them to something else which we are to enjoy." But enjoyment is to be found in irrational animals, as stated above (Q. 11, A. 2). Much more, therefore, is it possible for them to use.
Obj. 2: Further, to apply the members to action is to use them. But irrational animals apply their members to action; for instance, their feet, to walk; their horns, to strike. Therefore it is possible for irrational animals to use.
On the contrary,Augustine says (QQ. 83, qu. 30): "None but a rational animal can make use of a thing."
I answer that,as stated above (A. 1), to use is to apply an active principle to action: thus to consent is to apply the appetitive movement to the desire of something, as stated above (Q. 15, AA. 1, 2, 3). Now he alone who has the disposal of a thing, can apply it to something else; and this belongs to him alone who knows how to refer it to something else, which is an act of the reason. And therefore none but a rational animal consents and uses.
Reply Obj. 1: To enjoy implies the absolute movement of the appetite to the appetible: whereas to use implies a movement of the appetite to something as directed to something else. If therefore we compare use and enjoyment in respect of their objects, enjoyment is better than use; because that which is appetible absolutely is better than that which is appetible only as directed to something else. But if we compare them in respect of the apprehensive power that precedes them, greater excellence is required on the part of use: because to direct one thing to another is an act of reason; whereas to apprehend something absolutely is within the competency even of sense.
Reply Obj. 2: Animals by means of their members do something from natural instinct; not through knowing the relation of their members to these operations. Wherefore, properly speaking, they do not apply their members to action, nor do they use them. ________________________
THIRD ARTICLE [I-II, Q. 16, Art. 3]
Whether Use Regards Also the Last End?
Objection 1: It would seem that use can regard also the last end. For Augustine says (De Trin. x, 11): "Whoever enjoys, uses." But man enjoys the last end. Therefore he uses the last end.
Obj. 2: Further, "to use is to apply something to the purpose of the will" (De Trin. x, 11). But the last end, more than anything else, is the object of the will's application. Therefore it can be the object of use.
Obj. 3: Further, Hilary says (De Trin. ii) that "Eternity is in the Father, Likeness in the Image," i.e. in the Son, "Use in the Gift," i.e. in the Holy Ghost. But the Holy Ghost, since He is God, is the last end. Therefore the last end can be the object of use.
On the contrary,Augustine says (QQ. 83, qu. 30): "No one rightly uses God, but one enjoys Him." But God alone is the last end. Therefore we cannot use the last end.
I answer that,Use, as stated above (A. 1), implies the application of one thing to another. Now that which is applied to another is regarded in the light of means to an end; and consequently use always regards the means. For this reason things that are adapted to a certain end are said to be "useful"; in fact their very usefulness is sometimes called use.
It must, however, be observed that the last end may be taken in two ways: first, simply; secondly, in respect of an individual. For since the end, as stated above (Q. 1, A. 8; Q. 2, A. 7), signifies sometimes the thing itself, and sometimes the attainment or possession of that thing (thus the miser's end is either money or the possession of it); it is evident that, simply speaking, the last end is the thing itself; for the possession of money is good only inasmuch as there is some good in money. But in regard to the individual, the obtaining of money is the last end; for the miser would not seek for money, save that he might have it. Therefore, simply and properly speaking, a man enjoys money, because he places his last end therein; but in so far as he seeks to possess it, he is said to use it.
Reply Obj. 1: Augustine is speaking of use in general, in so far as it implies the relation of an end to the enjoyment which a man seeks in that end.
Reply Obj. 2: The end is applied to the purpose of the will, that the will may find rest in it. Consequently this rest in the end, which is the enjoyment thereof, is in this sense called use of the end. But the means are applied to the will's purpose, not only in being used as means, but as ordained to something else in which the will finds rest.
Reply Obj. 3: The words of Hilary refer to use as applicable to rest in the last end; just as, speaking in a general sense, one may be said to use the end for the purpose of attaining it, as stated above. Hence Augustine says (De Trin. vi, 10) that "this love, delight, felicity, or happiness, is called use by him." ________________________
FOURTH ARTICLE [I-II, Q. 16, Art. 4]
Whether Use Precedes Choice?
Objection 1: It would seem that use precedes choice. For nothing follows after choice, except execution. But use, since it belongs to the will, precedes execution. Therefore it precedes choice also.
Obj. 2: Further, the absolute precedes the relative. Therefore the less relative precedes the more relative. But choice implies two relations: one, of the thing chosen, in relation to the end; the other, of the thing chosen, in respect of that to which it is preferred; whereas use implies relation to the end only. Therefore use precedes choice.
Obj. 3: Further, the will uses the other powers in so far as it removes them. But the will moves itself, too, as stated above (Q. 9, A. 3). Therefore it uses itself, by applying itself to act. But it does this when it consents. Therefore there is use in consent. But consent precedes choice as stated above (Q. 15, A. 3, ad 3). Therefore use does also.
On the contrary,Damascene says (De Fide Orth. ii, 22) that "the will after choosing has an impulse to the operation, and afterwards it uses (the powers)." Therefore use follows choice.
I answer that,The will has a twofold relation to the thing willed. One, according as the thing willed is, in a way, in the willing subject, by a kind of proportion or order to the thing willed. Wherefore those things that are naturally proportionate to a certain end, are said to desire that end naturally. Yet to have an end thus is to have it imperfectly. Now every imperfect thing tends to perfection. And therefore both the natural and the voluntary appetite tend to have the end in reality; and this is to have it perfectly. This is the second relation of the will to the thing willed.
Now the thing willed is not only the end, but also the means. And the last act that belongs to the first relation of the will to the means, is choice; for there the will becomes fully proportionate, by willing the means fully. Use, on the other hand, belongs to the second relation of the will, in respect of which it tends to the realization of the thing willed. Wherefore it is evident that use follows choice; provided that by use we mean the will's use of the executive power in moving it. But since the will, in a way, moves the reason also, and uses it, we may take the use of the means, as consisting in the consideration of the reason, whereby it refers the means to the end. In this sense use precedes choice.
Reply Obj. 1: The motion of the will to the execution of the work, precedes execution, but follows choice. And so, since use belongs to that very motion of the will, it stands between choice and execution.
Reply Obj. 2: What is essentially relative is after the absolute; but the thing to which relation is referred need not come after. Indeed, the more a cause precedes, the more numerous the effects to which it has relation.
Reply Obj. 3: Choice precedes use, if they be referred to the same object. But nothing hinders the use of one thing preceding the choice of another. And since the acts of the will react on one another, in each act of the will we can find both consent and choice and use; so that we may say that the will consents to choose, and consents to consent, and uses itself in consenting and choosing. And such acts as are ordained to that which precedes, precede also. ________________________
OF THE ACTS COMMANDED BY THE WILL (In Nine Articles)
We must now consider the acts commanded by the will; under which head there are nine points of inquiry:
(1) Whether command is an act of the will or of the reason?
(2) Whether command belongs to irrational animals?
(3) Of the order between command and use;
(4) Whether command and the commanded act are one act or distinct?
(5) Whether the act of the will is commanded?
(6) Whether the act of the reason is commanded?
(7) Whether the act of the sensitive appetite is commanded?
(8) Whether the act of the vegetal soul is commanded?
(9) Whether the acts of the external members are commanded? ________________________
FIRST ARTICLE [I-II, Q. 17, Art. 1]
Whether Command Is an Act of the Reason or of the Will?
Objection 1: It would seem that command is not an act of the reason but of the will. For command is a kind of motion; because Avicenna says that there are four ways of moving, "by perfecting, by disposing, by commanding, and by counselling." But it belongs to the will to move all the other powers of the soul, as stated above (Q. 9, A. 1). Therefore command is an act of the will.
Obj. 2: Further, just as to be commanded belongs to that which is subject, so, seemingly, to command belongs to that which is most free. But the root of liberty is especially in the will. Therefore to command belongs to the will.
Obj. 3: Further, command is followed at once by act. But the act of the reason is not followed at once by act: for he who judges that a thing should be done, does not do it at once. Therefore command is not an act of the reason, but of the will.
On the contrary,Gregory of Nyssa [*Nemesius, De Nat. Hom. xvi.] and the Philosopher (Ethic. i, 13) say that "the appetite obeys reason." Therefore command is an act of the reason.
I answer that,Command is an act of the reason presupposing, however, an act of the will. In proof of this, we must take note that, since the acts of the reason and of the will can be brought to bear on one another, in so far as the reason reasons about willing, and the will wills to reason, the result is that the act of the reason precedes the act of the will, and conversely. And since the power of the preceding act continues in the act that follows, it happens sometimes that there is an act of the will in so far as it retains in itself something of an act of the reason, as we have stated in reference to use and choice; and conversely, that there is an act of the reason in so far as it retains in itself something of an act of the will.
Now, command is essentially indeed an act of the reason: for the commander orders the one commanded to do something, by way of intimation or declaration; and to order thus by intimating or declaring is an act of the reason. Now the reason can intimate or declare something in two ways. First, absolutely: and this intimation is expressed by a verb in the indicative mood, as when one person says to another: "This is what you should do." Sometimes, however, the reason intimates something to a man by moving him thereto; and this intimation is expressed by a verb in the imperative mood; as when it is said to someone: "Do this." Now the first mover, among the powers of the soul, to the doing of an act is the will, as stated above (Q. 9, A. 1). Since therefore the second mover does not move, save in virtue of the first mover, it follows that the very fact that the reason moves by commanding, is due to the power of the will. Consequently it follows that command is an act of the reason, presupposing an act of the will, in virtue of which the reason, by its command, moves (the power) to the execution of the act.
Reply Obj. 1: To command is to move, not anyhow, but by intimating and declaring to another; and this is an act of the reason.
Reply Obj. 2: The root of liberty is the will as the subject thereof; but it is the reason as its cause. For the will can tend freely towards various objects, precisely because the reason can have various perceptions of good. Hence philosophers define the free-will as being "a free judgment arising from reason," implying that reason is the root of liberty.
Reply Obj. 3: This argument proves that command is an act of reason not absolutely, but with a kind of motion as stated above. ________________________
SECOND ARTICLE [I-II, Q. 17, Art. 2]
Whether Command Belongs to Irrational Animals?
Objection 1: It would seem that command belongs to irrational animals. Because, according to Avicenna, "the power that commands movement is the appetite; and the power that executes movement is in the muscles and nerves." But both powers are in irrational animals. Therefore command is to be found in irrational animals.
Obj. 2: Further, the condition of a slave is that of one who receives commands. But the body is compared to the soul as a slave to his master, as the Philosopher says (Polit. i, 2). Therefore the body is commanded by the soul, even in irrational animals, since they are composed of soul and body.
Obj. 3: Further, by commanding, man has an impulse towards an action.But impulse to action is to be found in irrational animals, asDamascene says (De Fide Orth. ii, 22). Therefore command is to befound in irrational animals.
On the contrary,Command is an act of reason, as stated above (A. 1). But in irrational animals there is no reason. Neither, therefore, is there command.
I answer that,To command is nothing else than to direct someone to do something, by a certain motion of intimation. Now to direct is the proper act of reason. Wherefore it is impossible that irrational animals should command in any way, since they are devoid of reason.
Reply Obj. 1: The appetitive power is said to command movement, in so far as it moves the commanding reason. But this is only in man. In irrational animals the appetitive power is not, properly speaking, a commanding faculty, unless command be taken loosely for motion.
Reply Obj. 2: The body of the irrational animal is competent to obey; but its soul is not competent to command, because it is not competent to direct. Consequently there is no ratio there of commander and commanded; but only of mover and moved.
Reply Obj. 3: Impulse to action is in irrational animals otherwise than in man. For the impulse of man to action arises from the directing reason; wherefore his impulse is one of command. On the other hand, the impulse of the irrational animal arises from natural instinct; because as soon as they apprehend the fitting or the unfitting, their appetite is moved naturally to pursue or to avoid. Wherefore they are directed by another to act; and they themselves do not direct themselves to act. Consequently in them is impulse but not command. ________________________
THIRD ARTICLE [I-II, Q. 17, Art. 3]
Whether Use Precedes Command?
Objection 1: It would seem that use precedes command. For command is an act of the reason presupposing an act of the will, as stated above (A. 1). But, as we have already shown (Q. 16, A. 1), use is an act of the will. Therefore use precedes command.
Obj. 2: Further, command is one of those things that are ordained to the end. But use is of those things that are ordained to the end. Therefore it seems that use precedes command.
Obj. 3: Further, every act of a power moved by the will is called use; because the will uses the other powers, as stated above (Q. 16, A. 1). But command is an act of the reason as moved by the will, as stated above (A. 1). Therefore command is a kind of use. Now the common precedes the proper. Therefore use precedes command.
On the contrary,Damascene says (De Fide Orth. ii, 22) that impulse to action precedes use. But impulse to operation is given by command. Therefore command precedes use.
I answer that,use of that which is directed to the end, in so far as it is in the reason referring this to the end, precedes choice, as stated above (Q. 16, A. 4). Wherefore still more does it precede command. On the other hand, use of that which is directed to the end, in so far as it is subject to the executive power, follows command; because use in the user is united to the act of the thing used; for one does not use a stick before doing something with the stick. But command is not simultaneous with the act of the thing to which the command is given: for it naturally precedes its fulfilment, sometimes, indeed, by priority of time. Consequently it is evident that command precedes use.
Reply Obj. 1: Not every act of the will precedes this act of the reason which is command; but an act of the will precedes, viz. choice; and an act of the will follows, viz. use. Because after counsel's decision, which is reason's judgment, the will chooses; and after choice, the reason commands that power which has to do what was chosen; and then, last of all, someone's will begins to use, by executing the command of reason; sometimes it is another's will, when one commands another; sometimes the will of the one that commands, when he commands himself to do something.
Reply Obj. 2: Just as act ranks before power, so does the object rank before the act. Now the object of use is that which is directed to the end. Consequently, from the fact that command [itself is directed to the end, it may be concluded that command] precedes, rather than that it follows use.
Reply Obj. 3: Just as the act of the will in using the reason for the purpose of command, precedes the command; so also we may say that this act whereby the will uses the reason, is preceded by a command of reason; since the acts of these powers react on one another. ________________________
FOURTH ARTICLE [I-II, Q. 17, Art. 4]
Whether Command and the Commanded Act Are One Act, or Distinct?
Objection 1: It would seem that the commanded act is not one with the command itself. For the acts of different powers are themselves distinct. But the commanded act belongs to one power, and the command to another; since one is the power that commands, and the other is the power that receives the command. Therefore the commanded act is not one with the command.
Obj. 2: Further, whatever things can be separate from one another, are distinct: for nothing is severed from itself. But sometimes the commanded act is separate from the command: for sometimes the command is given, and the commanded act follows not. Therefore command is a distinct act from the act commanded.
Obj. 3: Further, whatever things are related to one another as precedent and consequent, are distinct. But command naturally precedes the commanded act. Therefore they are distinct.
On the contrary,The Philosopher says (Topic. iii, 2) that "where one thing is by reason of another, there is but one." But there is no commanded act unless by reason of the command. Therefore they are one.
I answer that,Nothing prevents certain things being distinct in one respect, and one in another respect. Indeed, every multitude is one in some respect, as Dionysius says (Div. Nom. xiii). But a difference is to be observed in this, that some are simply many, and one in a particular aspect: while with others it is the reverse. Now "one" is predicated in the same way as "being." And substance is being simply, whereas accident or being "of reason" is a being only in a certain respect. Wherefore those things that are one in substance are one simply, though many in a certain respect. Thus, in the genus substance, the whole composed of its integral or essential parts, is one simply: because the whole is being and substance simply, and the parts are being and substances in the whole. But those things which are distinct in substance, and one according to an accident, are distinct simply, and one in a certain respect: thus many men are one people, and many stones are one heap; which is unity of composition or order. In like manner also many individuals that are one in genus or species are many simply, and one in a certain respect: since to be one in genus or species is to be one according to the consideration of the reason.
Now just as in the genus of natural things, a whole is composed of matter and form (e.g. man, who is one natural being, though he has many parts, is composed of soul and body); so, in human acts, the act of a lower power is in the position of matter in regard to the act of a higher power, in so far as the lower power acts in virtue of the higher power moving it: for thus also the act of the first mover is as the form in regard to the act of its instrument. Hence it is evident that command and the commanded act are one human act, just as a whole is one, yet in its parts, many.
Reply Obj. 1: If the distinct powers are not ordained to one another, their acts are diverse simply. But when one power is the mover of the other, then their acts are, in a way, one: since "the act of the mover and the act of the thing moved are one act" (Phys. iii, 3).
Reply Obj. 2: The fact that command and the commanded act can be separated from one another shows that they are different parts. Because the parts of a man can be separated from one another, and yet they form one whole.
Reply Obj. 3: In those things that are many in parts, but one as a whole, nothing hinders one part from preceding another. Thus the soul, in a way, precedes the body; and the heart, the other members. ________________________
FIFTH ARTICLE [I-II, Q. 17, Art. 5]
Whether the Act of the Will Is Commanded?
Objection 1: It would seem that the act of the will is not commanded.For Augustine says (Confess. viii, 9): "The mind commands the mind towill, and yet it does not." But to will is the act of the will.Therefore the act of the will is not commanded.
Obj. 2: Further, to receive a command belongs to one who can understand the command. But the will cannot understand the command; for the will differs from the intellect, to which it belongs to understand. Therefore the act of the will is not commanded.
Obj. 3: Further, if one act of the will is commanded, for the same reason all are commanded. But if all the acts of the will are commanded, we must needs proceed to infinity; because the act of the will precedes the act of reason commanding, as stated above (A. 1); for if that act of the will be also commanded, this command will be preceded by another act of the reason, and so on to infinity. But to proceed to infinity is not possible. Therefore the act of the will is not commanded.
On the contrary,Whatever is in our power, is subject to our command. But the acts of the will, most of all, are in our power; since all our acts are said to be in our power, in so far as they are voluntary. Therefore the acts of the will are commanded by us.
I answer that,As stated above (A. 1), command is nothing else than the act of the reason directing, with a certain motion, something to act. Now it is evident that the reason can direct the act of the will: for just as it can judge it to be good to will something, so it can direct by commanding man to will. From this it is evident that an act of the will can be commanded.
Reply Obj. 1: As Augustine says (Confess. viii, 9) when the mind commands itself perfectly to will, then already it wills: but that sometimes it commands and wills not, is due to the fact that it commands imperfectly. Now imperfect command arises from the fact that the reason is moved by opposite motives to command or not to command: wherefore it fluctuates between the two, and fails to command perfectly.
Reply Obj. 2: Just as each of the members of the body works not for itself alone but for the whole body; thus it is for the whole body that the eye sees; so is it with the powers of the soul. For the intellect understands, not for itself alone, but for all the powers; and the will wills not only for itself, but for all the powers too. Wherefore man, in so far as he is endowed with intellect and will, commands the act of the will for himself.
Reply Obj. 3: Since command is an act of reason, that act is commanded which is subject to reason. Now the first act of the will is not due to the direction of the reason but to the instigation of nature, or of a higher cause, as stated above (Q. 9, A. 4). Therefore there is no need to proceed to infinity. ________________________
SIXTH ARTICLE [I-II, Q. 17, Art. 6]
Whether the Act of the Reason Is Commanded?
Objection 1: It would seem that the act of the reason cannot be commanded. For it seems impossible for a thing to command itself. But it is the reason that commands, as stated above (A. 1). Therefore the act of the reason is not commanded.
Obj. 2: Further, that which is essential is different from that which is by participation. But the power whose act is commanded by reason, is rational by participation, as stated inEthic.i, 13. Therefore the act of that power, which is essentially rational, is not commanded.
Obj. 3: Further, that act is commanded, which is in our power. But to know and judge the truth, which is the act of reason, is not always in our power. Therefore the act of the reason cannot be commanded.
On the contrary,That which we do of our free-will, can be done by our command. But the acts of the reason are accomplished through the free-will: for Damascene says (De Fide Orth. ii, 22) that "by his free-will man inquires, considers, judges, approves." Therefore the acts of the reason can be commanded.
I answer that,Since the reason reacts on itself, just as it directs the acts of other powers, so can it direct its own act. Consequently its act can be commanded.
But we must take note that the act of the reason may be considered in two ways. First, as to the exercise of the act. And considered thus, the act of the reason can always be commanded: as when one is told to be attentive, and to use one's reason. Secondly, as to the object; in respect of which two acts of the reason have to be noticed. One is the act whereby it apprehends the truth about something. This act is not in our power: because it happens in virtue of a natural or supernatural light. Consequently in this respect, the act of the reason is not in our power, and cannot be commanded. The other act of the reason is that whereby it assents to what it apprehends. If, therefore, that which the reason apprehends is such that it naturally assents thereto, e.g. the first principles, it is not in our power to assent or dissent to the like: assent follows naturally, and consequently, properly speaking, is not subject to our command. But some things which are apprehended do not convince the intellect to such an extent as not to leave it free to assent or dissent, or at least suspend its assent or dissent, on account of some cause or other; and in such things assent or dissent is in our power, and is subject to our command.
Reply Obj. 1: Reason commands itself, just as the will moves itself, as stated above (Q. 9, A. 3), that is to say, in so far as each power reacts on its own acts, and from one thing tends to another.
Reply Obj. 2: On account of the diversity of objects subject to the act of the reason, nothing prevents the reason from participating in itself: thus the knowledge of principles is participated in the knowledge of the conclusions.
The reply to the third object is evident from what has been said. ________________________
SEVENTH ARTICLE [I-II, Q. 17, Art. 7]
Whether the Act of the Sensitive Appetite Is Commanded?
Objection 1: It would seem that the act of the sensitive appetite is not commanded. For the Apostle says (Rom. 7:15): "For I do not that good which I will": and a gloss explains this by saying that man lusts, although he wills not to lust. But to lust is an act of the sensitive appetite. Therefore the act of the sensitive appetite is not subject to our command.
Obj. 2: Further, corporeal matter obeys God alone, to the effect of formal transmutation, as was shown in the First Part (Q. 65, A. 4; Q. 91, A. 2; Q. 110, A. 2). But the act of the sensitive appetite is accompanied by a formal transmutation of the body, consisting in heat or cold. Therefore the act of the sensitive appetite is not subject to man's command.
Obj. 3: Further, the proper motive principle of the sensitive appetite is something apprehended by sense or imagination. But it is not always in our power to apprehend something by sense or imagination. Therefore the act of the sensitive appetite is not subject to our command.
On the contrary,Gregory of Nyssa [*Nemesius, De Nat. Hom. xvi.] says: "That which obeys reason is twofold, the concupiscible and the irascible," which belong to the sensitive appetite. Therefore the act of the sensitive appetite is subject to the command of reason.
I answer that,An act is subject to our command, in so far as it is in our power, as stated above (A. 5). Consequently in order to understand in what manner the act of the sensitive appetite is subject to the command of reason, we must consider in what manner it is in our power. Now it must be observed that the sensitive appetite differs from the intellective appetite, which is called the will, in the fact that the sensitive appetite is a power of a corporeal organ, whereas the will is not. Again, every act of a power that uses a corporeal organ, depends not only on a power of the soul, but also on the disposition of that corporeal organ: thus the act of vision depends on the power of sight, and on the condition of the eye, which condition is a help or a hindrance to that act. Consequently the act of the sensitive appetite depends not only on the appetitive power, but also on the disposition of the body.
Now whatever part the power of the soul takes in the act, follows apprehension. And the apprehension of the imagination, being a particular apprehension, is regulated by the apprehension of reason, which is universal; just as a particular active power is regulated by a universal active power. Consequently in this respect the act of the sensitive appetite is subject to the command of reason. On the other hand, condition or disposition of the body is not subject to the command of reason: and consequently in this respect, the movement of the sensitive appetite is hindered from being wholly subject to the command of reason.
Moreover it happens sometimes that the movement of the sensitive appetite is aroused suddenly in consequence of an apprehension of the imagination of sense. And then such movement occurs without the command of reason: although reason could have prevented it, had it foreseen. Hence the Philosopher says (Polit. i, 2) that the reason governs the irascible and concupiscible not by a "despotic supremacy," which is that of a master over his slave; but by a "politic and royal supremacy," whereby the free are governed, who are not wholly subject to command.
Reply Obj. 1: That man lusts, although he wills not to lust, is due to a disposition of the body, whereby the sensitive appetite is hindered from perfect compliance with the command of reason. Hence the Apostle adds (Rom. 7:15): "I see another law in my members, fighting against the law of my mind." This may also happen through a sudden movement of concupiscence, as stated above.
Reply Obj. 2: The condition of the body stands in a twofold relation to the act of the sensitive appetite. First, as preceding it: thus a man may be disposed in one way or another, in respect of his body, to this or that passion. Secondly, as consequent to it: thus a man becomes heated through anger. Now the condition that precedes, is not subject to the command of reason: since it is due either to nature, or to some previous movement, which cannot cease at once. But the condition that is consequent, follows the command of reason: since it results from the local movement of the heart, which has various movements according to the various acts of the sensitive appetite.
Reply Obj. 3: Since the external sensible is necessary for the apprehension of the senses, it is not in our power to apprehend anything by the senses, unless the sensible be present; which presence of the sensible is not always in our power. For it is then that man can use his senses if he will so to do; unless there be some obstacle on the part of the organ. On the other hand, the apprehension of the imagination is subject to the ordering of reason, in proportion to the strength or weakness of the imaginative power. For that man is unable to imagine the things that reason considers, is either because they cannot be imagined, such as incorporeal things; or because of the weakness of the imaginative power, due to some organic indisposition. ________________________
EIGHTH ARTICLE [I-II, Q. 17, Art. 8]
Whether the Act of the Vegetal Soul Is Commanded?
Objection 1: It would seem that the acts of the vegetal soul are subject to the command of reason. For the sensitive powers are of higher rank than the vegetal powers. But the powers of the sensitive soul are subject to the command of reason. Much more, therefore, are the powers of the vegetal soul.
Obj. 2: Further, man is called a "little world" [*Aristotle,Phys.viii. 2], because the soul is in the body, as God is in the world. But God is in the world in such a way, that everything in the world obeys His command. Therefore all that is in man, even the powers of the vegetal soul, obey the command of reason.
Obj. 3: Further, praise and blame are awarded only to such acts as are subject to the command of reason. But in the acts of the nutritive and generative power, there is room for praise and blame, virtue and vice: as in the case of gluttony and lust, and their contrary virtues. Therefore the acts of these powers are subject to the command of reason.
On the contrary,Gregory of Nyssa [*Nemesius, De Nat. Hom. xxii.] says that "the nutritive and generative power is one over which the reason has no control."
I answer that,Some acts proceed from the natural appetite, others from the animal, or from the intellectual appetite: for every agent desires an end in some way. Now the natural appetite does not follow from some apprehension, as [d]o the animal and the intellectual appetite. But the reason commands by way of apprehensive power. Wherefore those acts that proceed from the intellective or the animal appetite, can be commanded by reason: but not those acts that proceed from the natural appetite. And such are the acts of the vegetal soul; wherefore Gregory of Nyssa (Nemesius, De Nat. Hom. xxii) says "that generation and nutrition belong to what are called natural powers." Consequently the acts of the vegetal soul are not subject to the command of reason.
Reply Obj. 1: The more immaterial an act is, the more noble it is, and the more is it subject to the command of reason. Hence the very fact that the acts of the vegetal soul do not obey reason, shows that they rank lowest.
Reply Obj. 2: The comparison holds in a certain respect: because, to wit, as God moves the world, so the soul moves the body. But it does not hold in every respect: for the soul did not create the body out of nothing, as God created the world; for which reason the world is wholly subject to His command.
Reply Obj. 3: Virtue and vice, praise and blame do not affect the acts themselves of the nutritive and generative power, i.e. digestion, and formation of the human body; but they affect the acts of the sensitive part, that are ordained to the acts of generation and nutrition; for example the desire for pleasure in the act of taking food or in the act of generation, and the right or wrong use thereof. ________________________
NINTH ARTICLE [I-II, Q. 17, Art. 9]
Whether the Acts of the External Members Are Commanded?
Objection 1: It would seem that the members of the body do not obey reason as to their acts. For it is evident that the members of the body are more distant from the reason, than the powers of the vegetal soul. But the powers of the vegetal soul do not obey reason, as stated above (A. 8). Therefore much less do the members of the body obey.
Obj. 2: Further, the heart is the principle of animal movement. But the movement of the heart is not subject to the command of reason: for Gregory of Nyssa [*Nemesius, De Nat. Hom. xxii.] says that "the pulse is not controlled by reason." Therefore the movement of the bodily members is not subject to the command of reason.
Obj. 3: Further, Augustine says (De Civ. Dei xiv, 16) that "the movement of the genital members is sometimes inopportune and not desired; sometimes when sought it fails, and whereas the heart is warm with desire, the body remains cold." Therefore the movements of the members are not obedient to reason.
On the contrary,Augustine says (Confess. viii, 9): "The mind commands a movement of the hand, and so ready is the hand to obey, that scarcely can one discern obedience from command."
I answer that,The members of the body are organs of the soul's powers. Consequently according as the powers of the soul stand in respect of obedience to reason, so do the members of the body stand in respect thereof. Since then the sensitive powers are subject to the command of reason, whereas the natural powers are not; therefore all movements of members, that are moved by the sensitive powers, are subject to the command of reason; whereas those movements of members, that arise from the natural powers, are not subject to the command of reason.
Reply Obj. 1: The members do not move themselves, but are moved through the powers of the soul; of which powers, some are in closer contact with the reason than are the powers of the vegetal soul.
Reply Obj. 2: In things pertaining to intellect and will, that which is according to nature stands first, whence all other things are derived: thus from the knowledge of principles that are naturally known, is derived knowledge of the conclusions; and from volition of the end naturally desired, is derived the choice of the means. So also in bodily movements the principle is according to nature. Now the principle of bodily movements begins with the movement of the heart. Consequently the movement of the heart is according to nature, and not according to the will: for like a proper accident, it results from life, which follows from the union of soul and body. Thus the movement of heavy and light things results from their substantial form: for which reason they are said to be moved by their generator, as the Philosopher states (Phys. viii, 4). Wherefore this movement is called "vital." For which reason Gregory of Nyssa (Nemesius, De Nat. Hom. xxii) says that, just as the movement of generation and nutrition does not obey reason, so neither does the pulse which is a vital movement. By the pulse he means the movement of the heart which is indicated by the pulse veins.
Reply Obj. 3: As Augustine says (De Civ. Dei xiv, 17, 20) it is in punishment of sin that the movement of these members does not obey reason: in this sense, that the soul is punished for its rebellion against God, by the insubmission of that member whereby original sin is transmitted to posterity.
But because, as we shall state later on, the effect of the sin of our first parent was that his nature was left to itself, through the withdrawal of the supernatural gift which God had bestowed on man, we must consider the natural cause of this particular member's insubmission to reason. This is stated by Aristotle (De Causis Mot. Animal.) who says that "the movements of the heart and of the organs of generation are involuntary," and that the reason of this is as follows. These members are stirred at the occasion of some apprehension; in so far as the intellect and imagination represent such things as arouse the passions of the soul, of which passions these movements are a consequence. But they are not moved at the command of the reason or intellect, because these movements are conditioned by a certain natural change of heat and cold, which change is not subject to the command of reason. This is the case with these two organs in particular, because each is as it were a separate animal being, in so far as it is a principle of life; and the principle is virtually the whole. For the heart is the principle of the senses; and from the organ of generation proceeds the seminal virtue, which is virtually the entire animal. Consequently they have their proper movements naturally: because principles must needs be natural, as stated above (Reply Obj. 2). ________________________
OF THE GOOD AND EVIL OF HUMAN ACTS, IN GENERAL (In Eleven Articles)
We must now consider the good and evil of human acts. First, how a human act is good or evil; secondly, what results from the good or evil of a human act, as merit or demerit, sin and guilt.
Under the first head there will be a threefold consideration: the first will be of the good and evil of human acts, in general; the second, of the good and evil of internal acts; the third, of the good and evil of external acts.
Concerning the first there are eleven points of inquiry:
(1) Whether every human action is good, or are there evil actions?
(2) Whether the good or evil of a human action is derived from its object?
(3) Whether it is derived from a circumstance?
(4) Whether it is derived from the end?
(5) Whether a human action is good or evil in its species?
(6) Whether an action has the species of good or evil from its end?
(7) Whether the species derived from the end is contained under the species derived from the object, as under its genus, or conversely?
(8) Whether any action is indifferent in its species?
(9) Whether an individual action can be indifferent?
(10) Whether a circumstance places a moral action in the species of good or evil?
(11) Whether every circumstance that makes an action better or worse, places the moral action in the species of good or evil? ________________________
FIRST ARTICLE [I-II, Q. 18, Art. 1]
Whether Every Human Action Is Good, or Are There Evil Actions?
Objection 1: It would seem that every human action is good, and that none is evil. For Dionysius says (Div. Nom. iv) that evil acts not, save in virtue of the good. But no evil is done in virtue of the good. Therefore no action is evil.
Obj. 2: Further, nothing acts except in so far as it is in act. Now a thing is evil, not according as it is in act, but according as its potentiality is void of act; whereas in so far as its potentiality is perfected by act, it is good, as stated inMetaph.ix, 9. Therefore nothing acts in so far as it is evil, but only according as it is good. Therefore every action is good, and none is evil.
Obj. 3: Further, evil cannot be a cause, save accidentally, as Dionysius declares (Div. Nom. iv). But every action has some effect which is proper to it. Therefore no action is evil, but every action is good.
On the contrary,Our Lord said (John 3:20): "Every one that doth evil, hateth the light." Therefore some actions of man are evil.
I answer that,We must speak of good and evil in actions as of good and evil in things: because such as everything is, such is the act that it produces. Now in things, each one has so much good as it has being: since good and being are convertible, as was stated in the First Part (Q. 5, AA. 1, 3). But God alone has the whole plenitude of His Being in a certain unity: whereas every other thing has its proper fulness of being in a certain multiplicity. Wherefore it happens with some things, that they have being in some respect, and yet they are lacking in the fulness of being due to them. Thus the fulness of human being requires a compound of soul and body, having all the powers and instruments of knowledge and movement: wherefore if any man be lacking in any of these, he is lacking in something due to the fulness of his being. So that as much as he has of being, so much has he of goodness: while so far as he is lacking in goodness, and is said to be evil: thus a blind man is possessed of goodness inasmuch as he lives; and of evil, inasmuch as he lacks sight. That, however, which has nothing of being or goodness, could not be said to be either evil or good. But since this same fulness of being is of the very essence of good, if a thing be lacking in its due fulness of being, it is not said to be good simply, but in a certain respect, inasmuch as it is a being; although it can be called a being simply, and a non-being in a certain respect, as was stated in the First Part (Q. 5, A. 1, ad 1). We must therefore say that every action has goodness, in so far as it has being; whereas it is lacking in goodness, in so far as it is lacking in something that is due to its fulness of being; and thus it is said to be evil: for instance if it lacks the quantity determined by reason, or its due place, or something of the kind.
Reply Obj. 1: Evil acts in virtue of deficient goodness. For if there were nothing of good there, there would be neither being nor possibility of action. On the other hand if good were not deficient, there would be no evil. Consequently the action done is a deficient good, which is good in a certain respect, but simply evil.
Reply Obj. 2: Nothing hinders a thing from being in act in a certain respect, so that it can act; and in a certain respect deficient in act, so as to cause a deficient act. Thus a blind man has in act the power of walking, whereby he is able to walk; but inasmuch as he is deprived of sight he suffers a defect in walking by stumbling when he walks.
Reply Obj. 3: An evil action can have a proper effect, according to the goodness and being that it has. Thus adultery is the cause of human generation, inasmuch as it implies union of male and female, but not inasmuch as it lacks the order of reason. ________________________
SECOND ARTICLE [I-II, Q. 18, Art. 2]
Whether the Good or Evil of a Man's Action Is Derived from Its Object?
Objection 1: It would seem that the good or evil of an action is not derived from its object. For the object of any action is a thing. But "evil is not in things, but in the sinner's use of them," as Augustine says (De Doctr. Christ. iii, 12). Therefore the good or evil of a human action is not derived from their object.
Obj. 2: Further, the object is compared to the action as its matter. But the goodness of a thing is not from its matter, but rather from the form, which is an act. Therefore good and evil in actions is not derived from their object.
Obj. 3: Further, the object of an active power is compared to the action as effect to cause. But the goodness of a cause does not depend on its effect; rather is it the reverse. Therefore good or evil in actions is not derived from their object.
On the contrary,It is written (Osee 9:10): "They became abominable as those things which they loved." Now man becomes abominable to God on account of the malice of his action. Therefore the malice of his action is according to the evil objects that man loves. And the same applies to the goodness of his action.
I answer that,as stated above (A. 1) the good or evil of an action, as of other things, depends on its fulness of being or its lack of that fulness. Now the first thing that belongs to the fulness of being seems to be that which gives a thing its species. And just as a natural thing has its species from its form, so an action has its species from its object, as movement from its term. And therefore just as the primary goodness of a natural thing is derived from its form, which gives it its species, so the primary goodness of a moral action is derived from its suitable object: hence some call such an action "good in its genus"; for instance, "to make use of what is one's own." And just as, in natural things, the primary evil is when a generated thing does not realize its specific form (for instance, if instead of a man, something else be generated); so the primary evil in moral actions is that which is from the object, for instance, "to take what belongs to another." And this action is said to be "evil in its genus," genus here standing for species, just as we apply the term "mankind" to the whole human species.
