Thomas Aquinas - Summa Theologica, Part I-II (Pars Prima Secundae)

Obj. 2: Further, action is distinct from contemplation. But choice has a place even in contemplation; in so far as one opinion is preferred to another. Therefore choice is not concerned with human acts alone.

Obj. 3: Further, men are chosen for certain posts, whether secular or ecclesiastical, by those who exercise no action in their regard. Therefore choice is not concerned with human acts alone.

On the contrary, The Philosopher says (Ethic. iii, 2) that "no man chooses save what he can do himself."

I answer that, Just as intention regards the end, so does choice regard the means. Now the end is either an action or a thing. And when the end is a thing, some human action must intervene; either in so far as man produces the thing which is the end, as the physician produces health (wherefore the production of health is said to be the end of the physician); or in so far as man, in some fashion, uses or enjoys the thing which is the end; thus for the miser, money or the possession of money is the end. The same is to be said of the means. For the means must needs be either an action; or a thing, with some action intervening whereby man either makes the thing which is the means, or puts it to some use. And thus it is that choice is always in regard to human acts.

Reply Obj. 1: The organs are ordained to the end, inasmuch as man makes use of them for the sake of the end.

Reply Obj. 2: In contemplation itself there is the act of the intellect assenting to this or that opinion. It is exterior action that is put in contradistinction to contemplation.

Reply Obj. 3: When a man chooses someone for a bishopric or some high position in the state, he chooses to name that man to that post. Else, if he had no right to act in the appointment of the bishop or official, he would have no right to choose. Likewise, whenever we speak of one thing being chosen in preference to another, it is in conjunction with some action of the chooser. ________________________

FIFTH ARTICLE [I-II, Q. 13, Art. 5]

Whether Choice Is Only of Possible Things?

Objection 1: It would seem that choice is not only of possible things. For choice is an act of the will, as stated above (A. 1). Now there is "a willing of impossibilities" (Ethic. iii, 2). Therefore there is also a choice of impossibilities.

Obj. 2: Further, choice is of things done by us, as stated above (A. 4). Therefore it matters not, as far as the act of choosing is concerned, whether one choose that which is impossible in itself, or that which is impossible to the chooser. Now it often happens that we are unable to accomplish what we choose: so that this proves to be impossible to us. Therefore choice is of the impossible.

Obj. 3: Further, to try to do a thing is to choose to do it. But the Blessed Benedict says (Regula lxviii) that if the superior command what is impossible, it should be attempted. Therefore choice can be of the impossible.

On the contrary, The Philosopher says (Ethic. iii, 2) that "there is no choice of impossibilities."

I answer that, As stated above (A. 4), our choice is always concerned with our actions. Now whatever is done by us, is possible to us. Therefore we must needs say that choice is only of possible things.

Moreover, the reason for choosing a thing is that it conduces to an end. But what is impossible cannot conduce to an end. A sign of this is that when men in taking counsel together come to something that is impossible to them, they depart, as being unable to proceed with the business.

Again, this is evident if we examine the previous process of the reason. For the means, which are the object of choice, are to the end, as the conclusion is to the principle. Now it is clear that an impossible conclusion does not follow from a possible principle. Wherefore an end cannot be possible, unless the means be possible. Now no one is moved to the impossible. Consequently no one would tend to the end, save for the fact that the means appear to be possible. Therefore the impossible is not the object of choice.

Reply Obj. 1: The will stands between the intellect and the external action: for the intellect proposes to the will its object, and the will causes the external action. Hence the principle of the movement in the will is to be found in the intellect, which apprehends something under the universal notion of good: but the term or perfection of the will's act is to be observed in its relation to the action whereby a man tends to the attainment of a thing; for the movement of the will is from the soul to the thing. Consequently the perfect act of the will is in respect of something that is good for one to do. Now this cannot be something impossible. Wherefore the complete act of the will is only in respect of what is possible and good for him that wills. But the incomplete act of the will is in respect of the impossible; and by some is called "velleity," because, to wit, one would will ( vellet ) such a thing, were it possible. But choice is an act of the will, fixed on something to be done by the chooser. And therefore it is by no means of anything but what is possible.

Reply Obj. 2: Since the object of the will is the apprehended good, we must judge of the object of the will according as it is apprehended. And so, just as sometimes the will tends to something which is apprehended as good, and yet is not really good; so is choice sometimes made of something apprehended as possible to the chooser, and yet impossible to him.

Reply Obj. 3: The reason for this is that the subject should not rely on his own judgment to decide whether a certain thing is possible; but in each case should stand by his superior's judgment. ________________________

SIXTH ARTICLE [I-II, Q. 13, Art. 6]

Whether Man Chooses of Necessity or Freely?

Objection 1: It would seem that man chooses of necessity. For the end stands in relation to the object of choice, as the principle of that which follows from the principles, as declared in Ethic. vii, 8. But conclusions follow of necessity from their principles. Therefore man is moved of necessity from (willing) the end of the choice (of the means).

Obj. 2: Further, as stated above (A. 1, ad 2), choice follows the reason's judgment of what is to be done. But reason judges of necessity about some things: on account of the necessity of the premises. Therefore it seems that choice also follows of necessity.

Obj. 3: Further, if two things are absolutely equal, man is not moved to one more than to the other; thus if a hungry man, as Plato says (Cf. De Coelo ii, 13), be confronted on either side with two portions of food equally appetizing and at an equal distance, he is not moved towards one more than to the other; and he finds the reason of this in the immobility of the earth in the middle of the world. Now, if that which is equally (eligible) with something else cannot be chosen, much less can that be chosen which appears as less (eligible). Therefore if two or more things are available, of which one appears to be more (eligible), it is impossible to choose any of the others. Therefore that which appears to hold the first place is chosen of necessity. But every act of choosing is in regard to something that seems in some way better. Therefore every choice is made necessarily.

On the contrary, Choice is an act of a rational power; which according to the Philosopher (Metaph. ix, 2) stands in relation to opposites.

I answer that, Man does not choose of necessity. And this is because that which is possible not to be, is not of necessity. Now the reason why it is possible not to choose, or to choose, may be gathered from a twofold power in man. For man can will and not will, act and not act; again, he can will this or that, and do this or that. The reason of this is seated in the very power of the reason. For the will can tend to whatever the reason can apprehend as good. Now the reason can apprehend as good, not only this, viz. "to will" or "to act," but also this, viz. "not to will" or "not to act." Again, in all particular goods, the reason can consider an aspect of some good, and the lack of some good, which has the aspect of evil: and in this respect, it can apprehend any single one of such goods as to be chosen or to be avoided. The perfect good alone, which is Happiness, cannot be apprehended by the reason as an evil, or as lacking in any way. Consequently man wills Happiness of necessity, nor can he will not to be happy, or to be unhappy. Now since choice is not of the end, but of the means, as stated above (A. 3); it is not of the perfect good, which is Happiness, but of other particular goods. Therefore man chooses not of necessity, but freely.
