Of the Voluntary and the Involuntary

Of the Voluntary and the Involuntary — St. Thomas Aquinas asks: Whether there is anything voluntary in human acts?; Whether there is anything voluntary in irrational animals?; Whether there can be voluntariness without any act?; Whether violence can be done to the will?; Whether violence causes involuntariness?; Whether fear causes involuntariness simply?; Whether concupiscence causes involuntariness?; Whether ignorance causes involuntariness?.

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 Passions. 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 appetite, 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 circumstances, according to which we form our judgment concerning them, we must first consider the voluntary and the involuntary, and afterwards, the circumstances of those acts which are found to be voluntary or involuntary. Under the first head there are eight points of inquiry:

Article 1: Whether there is anything voluntary in human acts?

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.

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 (); 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.

Article 2: Whether there is anything voluntary in irrational animals?

The Philosopher says (Ethic. iii, 2) that "both children and irrational animals participate in the voluntary." The same is said by Damascene (De Fide Orth. 24) and Gregory of Nyssa [*Nemesius, De Nat. Hom. xxxii.].

As stated above (), it is essential to the voluntary act that its principle be within the agent, together with some knowledge of the end. Now knowledge of the end is twofold; perfect and imperfect. Perfect knowledge of the end consists in not only apprehending the thing which is the end, but also in knowing it under the aspect of end, and the relationship of the means to that end. And such knowledge belongs to none but the rational nature. But imperfect knowledge of the end consists in mere apprehension of the end, without knowing it under the aspect of end, or the relationship of an act to the end. Such knowledge of the end is exercised by irrational animals, through their senses and their natural estimative power.

Consequently perfect knowledge of the end leads to the perfect voluntary; inasmuch as, having apprehended the end, a man can, from deliberating about the end and the means thereto, be moved, or not, to gain that end. But imperfect knowledge of the end leads to the imperfect voluntary; inasmuch as the agent apprehends the end, but does not deliberate, and is moved to the end at once. Wherefore the voluntary in its perfection belongs to none but the rational nature: whereas the imperfect voluntary is within the competency of even irrational animals.

Article 3: Whether there can be voluntariness without any act?

The word "voluntary" is applied to that of which we are masters. Now we are masters in respect of to act and not to act, to will and not to will. Therefore just as to act and to will are voluntary, so also are not to act and not to will.

Voluntary is what proceeds from the will. Now one thing proceeds from another in two ways. First, directly; in which sense something proceeds from another inasmuch as this other acts; for instance, heating from heat. Secondly, indirectly; in which sense something proceeds from another through this other not acting; thus the sinking of a ship is set down to the helmsman, from his having ceased to steer. But we must take note that the cause of what follows from want of action is not always the agent as not acting; but only then when the agent can and ought to act. For if the helmsman were unable to steer the ship or if the ship's helm be not entrusted to him, the sinking of the ship would not be set down to him, although it might be due to his absence from the helm.

Since, then, the will by willing and acting, is able, and sometimes ought, to hinder not-willing and not-acting; this not-willing and not-acting is imputed to, as though proceeding from, the will. And thus it is that we can have the voluntary without an act; sometimes without outward act, but with an interior act; for instance, when one wills not to act; and sometimes without even an interior act, as when one does not will to act.

Article 4: Whether violence can be done to the will?

Augustine says (De Civ. Dei v, 10) that what is done by the will is not done of necessity. Now, whatever is done under compulsion is done of necessity: consequently what is done by the will, cannot be compelled. Therefore the will cannot be compelled to act.

The act of the will is twofold: one is its immediate act, as it were, elicited by it, namely, "to wish"; the other is an act of the will commanded by it, and put into execution by means of some other power, such as "to walk" and "to speak," which are commanded by the will to be executed by means of the motive power.

As regards the commanded acts of the will, then, the will can suffer violence, in so far as violence can prevent the exterior members from executing the will's command. But as to the will's own proper act, violence cannot be done to the will.

The reason of this is that the act of the will is nothing else than an inclination proceeding from the interior principle of knowledge: just as the natural appetite is an inclination proceeding from an interior principle without knowledge. Now what is compelled or violent is from an exterior principle. Consequently it is contrary to the nature of the will's own act, that it should be subject to compulsion and violence: just as it is also contrary to the nature of a natural inclination or movement. For a stone may have an upward movement from violence, but that this violent movement be from its natural inclination is impossible. In like manner a man may be dragged by force: but it is contrary to the very notion of violence, that he be dragged of his own will.

Article 5: Whether violence causes involuntariness?

The Philosopher (Ethic. iii, 1) and Damascene (De Fide Orth. ii, 24) say that "things done under compulsion are involuntary."

Violence is directly opposed to the voluntary, as likewise to the natural. For the voluntary and the natural have this in common, that both are from an intrinsic principle; whereas violence is from an extrinsic principle. And for this reason, just as in things devoid of knowledge, violence effects something against nature: so in things endowed with knowledge, it effects something against the will. Now that which is against nature is said to be "unnatural"; and in like manner that which is against the will is said to be "involuntary." Therefore violence causes involuntariness.

Article 6: Whether fear causes involuntariness simply?

Gregory of Nyssa [*Nemesius, De Nat. Hom. xxx.] and the Philosopher (Ethic. iii, 1) say that such things as are done through fear are "voluntary rather than involuntary."

As the Philosopher says (Ethic. iii) and likewise Gregory of Nyssa in his book on Man (Nemesius, De Nat. Hom. xxx), such things are done through fear "are of a mixed character," being partly voluntary and partly involuntary. For that which is done through fear, considered in itself, is not voluntary; but it becomes voluntary in this particular case, in order, namely, to avoid the evil feared.

But if the matter be considered aright, such things are voluntary rather than involuntary; for they are voluntary simply, but involuntary in a certain respect. For a thing is said to be simply, according as it is in act; but according as it is only in apprehension, it is not simply, but in a certain respect. Now that which is done through fear, is in act in so far as it is done. For, since acts are concerned with singulars; and the singular, as such, is here and now; that which is done is in act, in so far as it is here and now and under other individuating circumstances. And that which is done through fear is voluntary, inasmuch as it is here and now, that is to say, in so far as, under the circumstances, it hinders a greater evil which was feared; thus the throwing of the cargo into the sea becomes voluntary during the storm, through fear of the danger: wherefore it is clear that it is voluntary simply. And hence it is that what is done out of fear is essentially voluntary, because its principle is within. But if we consider what is done through fear, as outside this particular case, and inasmuch as it is repugnant to the will, this is merely a consideration of the mind. And consequently what is done through fear is involuntary, considered in that respect, that is to say, outside the actual circumstances of the case.

Article 7: Whether concupiscence causes involuntariness?

Damascene says (De Fide Orth. ii, 24): "The involuntary act deserves mercy or indulgence, and is done with regret." But neither of these can be said of that which is done out of concupiscence. Therefore concupiscence does not cause involuntariness.

Concupiscence does not cause involuntariness, but on the contrary makes something to be voluntary. For a thing is said to be voluntary, from the fact that the will is moved to it. Now concupiscence inclines the will to desire the object of concupiscence. Therefore the effect of concupiscence is to make something to be voluntary rather than involuntary.

Article 8: Whether ignorance causes involuntariness?

Damascene (De Fide Orth. ii, 24) and the Philosopher (Ethic. iii, 1) say that "what is done through ignorance is involuntary."

If ignorance causes involuntariness, it is in so far as it deprives one of knowledge, which is a necessary condition of voluntariness, as was declared above (). But it is not every ignorance that deprives one of this knowledge. Accordingly, we must take note that ignorance has a threefold relationship to the act of the will: in one way, "concomitantly"; in another, "consequently"; in a third way, "antecedently." "Concomitantly," when there is ignorance of what is done; but, so that even if it were known, it would be done. For then, ignorance does not induce one to wish this to be done, but it just happens that a thing is at the same time done, and not known: thus in the example given (OBJ 3) a man did indeed wish to kill his foe, but killed him in ignorance, thinking to kill a stag. And ignorance of this kind, as the Philosopher states (Ethic. iii, 1), does not cause involuntariness, since it is not the cause of anything that is repugnant to the will: but it causes "non-voluntariness," since that which is unknown cannot be actually willed. Ignorance is "consequent" to the act of the will, in so far as ignorance itself is voluntary: and this happens in two ways, in accordance with the two aforesaid modes of voluntary (). First, because the act of the will is brought to bear on the ignorance: as when a man wishes not to know, that he may have an excuse for sin, or that he may not be withheld from sin; according to Job 21:14: "We desire not the knowledge of Thy ways." And this is called "affected ignorance." Secondly, ignorance is said to be voluntary, when it regards that which one can and ought to know: for in this sense "not to act" and "not to will" are said to be voluntary, as stated above (). And ignorance of this kind happens, either when one does not actually consider what one can and ought to consider; this is called "ignorance of evil choice," and arises from some passion or habit: or when one does not take the trouble to acquire the knowledge which one ought to have; in which sense, ignorance of the general principles of law, which one to know, is voluntary, as being due to negligence. Accordingly, if in either of these ways, ignorance is voluntary, it cannot cause involuntariness simply. Nevertheless it causes involuntariness in a certain respect, inasmuch as it precedes the movement of the will towards the act, which movement would not be, if there were knowledge. Ignorance is "antecedent" to the act of the will, when it is not voluntary, and yet is the cause of man's willing what he would not will otherwise. Thus a man may be ignorant of some circumstance of his act, which he was not bound to know, the result being that he does that which he would not do, if he knew of that circumstance; for instance, a man, after taking proper precaution, may not know that someone is coming along the road, so that he shoots an arrow and slays a passer-by. Such ignorance causes involuntariness simply.

From this may be gathered the solution of the objections. For the first objection deals with ignorance of what a man is bound to know. The second, with ignorance of choice, which is voluntary to a certain extent, as stated above. The third, with that ignorance which is concomitant with the act of the will.
