QUESTION 6

OF THE VOLUNTARY AND THE INVOLUNTARY (In Eight Articles)

Since therefore Happiness is to be gained by means of certain acts, we must in due sequence consider human acts, in order to know by what acts we may obtain Happiness, and by what acts we are prevented from obtaining it. But because operations and acts are concerned with things singular, consequently all practical knowledge is incomplete unless it take account of things in detail. The study of Morals, therefore, since it treats of human acts, should consider first the general principles; and secondly matters of detail.

In treating of the general principles, the points that offer themselves for our consideration are (1) human acts themselves; (2) their principles. Now of human acts some are proper to man; others are common to man and animals. And since Happiness is man's proper good, those acts which are proper to man have a closer connection with Happiness than have those which are common to man and the other animals. First, then, we must consider those acts which are proper to man; secondly, those acts which are common to man and the other animals, and are called Pa.s.sions. The first of these points offers a twofold consideration: (1) What makes a human act? (2) What distinguishes human acts?

And since those acts are properly called human which are voluntary, because the will is the rational appet.i.te, which is proper to man; we must consider acts in so far as they are voluntary.

First, then, we must consider the voluntary and involuntary in general; secondly, those acts which are voluntary, as being elicited by the will, and as issuing from the will immediately; thirdly, those acts which are voluntary, as being commanded by the will, which issue from the will through the medium of the other powers.

And because voluntary acts have certain circ.u.mstances, according to which we form our judgment concerning them, we must first consider the voluntary and the involuntary, and afterwards, the circ.u.mstances of those acts which are found to be voluntary or involuntary. Under the first head there are eight points of inquiry:

(1) Whether there is anything voluntary in human acts?

(2) Whether in irrational animals?

(3) Whether there can be voluntariness without any action?

(4) Whether violence can be done to the will?

(5) Whether violence causes involuntariness?

(6) Whether fear causes involuntariness?

(7) Whether concupiscence causes involuntariness?

(8) Whether ignorance causes involuntariness?

FIRST ARTICLE [I-II, Q. 6, Art. 1]

Whether There Is Anything Voluntary in Human Acts?

Objection 1: It would seem that there is nothing voluntary in human acts. For that is voluntary ”which has its principle within itself.”

as Gregory of Nyssa [*Nemesius, De Natura Hom. x.x.xii.], Damascene (De Fide Orth. ii, 24), and Aristotle (Ethic. iii, 1) declare. But the principle of human acts is not in man himself, but outside him: since man's appet.i.te is moved to act, by the appetible object which is outside him, and is as a ”mover unmoved” (De Anima iii, 10).

Therefore there is nothing voluntary in human acts.

Obj. 2: Further, the Philosopher (Phys. viii, 2) proves that in animals no new movement arises that is not preceded by a motion from without. But all human acts are new, since none is eternal.

Consequently, the principle of all human acts is from without: and therefore there is nothing voluntary in them.

Obj. 3: Further, he that acts voluntarily, can act of himself. But this is not true of man; for it is written (John 15:5): ”Without Me you can do nothing.” Therefore there is nothing voluntary in human acts.

_On the contrary,_ Damascene says (De Fide Orth. ii) that ”the voluntary is an act consisting in a rational operation.” Now such are human acts. Therefore there is something voluntary in human acts.

_I answer that,_ There must needs be something voluntary in human acts. In order to make this clear, we must take note that the principle of some acts or movements is within the agent, or that which is moved; whereas the principle of some movements or acts is outside. For when a stone is moved upwards, the principle of this movement is outside the stone: whereas when it is moved downwards, the principle of this movement is in the stone. Now of those things that are moved by an intrinsic principle, some move themselves, some not. For since every agent or thing moved, acts or is moved for an end, as stated above (Q. 1, A. 2); those are perfectly moved by an intrinsic principle, whose intrinsic principle is one not only of movement but of movement for an end. Now in order for a thing to be done for an end, some knowledge of the end is necessary. Therefore, whatever so acts or is moved by an intrinsic principle, that it has some knowledge of the end, has within itself the principle of its act, so that it not only acts, but acts for an end. On the other hand, if a thing has no knowledge of the end, even though it have an intrinsic principle of action or movement, nevertheless the principle of acting or being moved for an end is not in that thing, but in something else, by which the principle of its action towards an end is not in that thing, but in something else, by which the principle of its action towards an end is imprinted on it. Wherefore such like things are not said to move themselves, but to be moved by others.

But those things which have a knowledge of the end are said to move themselves because there is in them a principle by which they not only act but also act for an end. And consequently, since both are from an intrinsic principle, to wit, that they act and that they act for an end, the movements of such things are said to be voluntary: for the word ”voluntary” implies that their movements and acts are from their own inclination. Hence it is that, according to the definitions of Aristotle, Gregory of Nyssa, and Damascene [*See Objection 1], the voluntary is defined not only as having ”a principle within” the agent, but also as implying ”knowledge.” Therefore, since man especially knows the end of his work, and moves himself, in his acts especially is the voluntary to be found.
