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

On the contrary, 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."

I answer that, 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.

Reply Obj. 1: Things done through fear and compulsion differ not only according to present and future time, but also in this, that the will does not consent, but is moved entirely counter to that which is done through compulsion: whereas what is done through fear, becomes voluntary, because the will is moved towards it, albeit not for its own sake, but on account of something else, that is, in order to avoid an evil which is feared. For the conditions of a voluntary act are satisfied, if it be done on account of something else voluntary: since the voluntary is not only what we wish, for its own sake, as an end, but also what we wish for the sake of something else, as an end. It is clear therefore that in what is done from compulsion, the will does nothing inwardly; whereas in what is done through fear, the will does something. Accordingly, as Gregory of Nyssa [*Nemesius, De Nat. Hom. xxx.] says, in order to exclude things done through fear, a violent action is defined as not only one, "the princip[le] whereof is from without," but with the addition, "in which he that suffers violence concurs not at all"; because the will of him that is in fear, does concur somewhat in that which he does through fear.

Reply Obj. 2: Things that are such absolutely, remain such, whatever be added to them; for instance, a cold thing, or a white thing: but things that are such relatively, vary according as they are compared with different things. For what is big in comparison with one thing, is small in comparison with another. Now a thing is said to be voluntary, not only for its own sake, as it were absolutely; but also for the sake of something else, as it were relatively. Accordingly, nothing prevents a thing which was not voluntary in comparison with one thing, from becoming voluntary when compared with another.

Reply Obj. 3: That which is done through fear, is voluntary without any condition, that is to say, according as it is actually done: but it is involuntary, under a certain condition, that is to say, if such a fear were not threatening. Consequently, this argument proves rather the opposite. ________________________

SEVENTH ARTICLE [I-II, Q. 6, Art. 7]

Whether Concupiscence Causes Involuntariness?

Objection 1: It would seem that concupiscence causes involuntariness. For just as fear is a passion, so is concupiscence. But fear causes involuntariness to a certain extent. Therefore concupiscence does so too.

Obj. 2: Further, just as the timid man through fear acts counter to that which he proposed, so does the incontinent, through concupiscence. But fear causes involuntariness to a certain extent. Therefore concupiscence does so also.

Obj. 3: Further, knowledge is necessary for voluntariness. But concupiscence impairs knowledge; for the Philosopher says (Ethic. vi, 5) that "delight," or the lust of pleasure, "destroys the judgment of prudence." Therefore concupiscence causes involuntariness.

On the contrary, 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.

I answer that, 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.

Reply Obj. 1: Fear regards evil, but concupiscence regards good. Now evil of itself is counter to the will, whereas good harmonizes with the will. Therefore fear has a greater tendency than concupiscence to cause involuntariness.

Reply Obj. 2: He who acts from fear retains the repugnance of the will to that which he does, considered in itself. But he that acts from concupiscence, e.g. an incontinent man, does not retain his former will whereby he repudiated the object of his concupiscence; for his will is changed so that he desires that which previously he repudiated. Accordingly, that which is done out of fear is involuntary, to a certain extent, but that which is done from concupiscence is nowise involuntary. For the man who yields to concupiscence acts counter to that which he purposed at first, but not counter to that which he desires now; whereas the timid man acts counter to that which in itself he desires now.

Reply Obj. 3: If concupiscence were to destroy knowledge altogether, as happens with those whom concupiscence has rendered mad, it would follow that concupiscence would take away voluntariness. And yet properly speaking it would not result in the act being involuntary, because in things bereft of reason, there is neither voluntary nor involuntary. But sometimes in those actions which are done from concupiscence, knowledge is not completely destroyed, because the power of knowing is not taken away entirely, but only the actual consideration in some particular possible act. Nevertheless, this itself is voluntary, according as by voluntary we mean that which is in the power of the will, for example "not to act" or "not to will," and in like manner "not to consider"; for the will can resist the passion, as we shall state later on (Q. 10, A. 3; Q. 77, A.) ________________________

EIGHTH ARTICLE [I-II, Q. 6, Art. 8]

Whether Ignorance Causes Involuntariness?

Objection 1: It would seem that ignorance does not cause involuntariness. For "the involuntary act deserves pardon," as Damascene says (De Fide Orth. ii, 24). But sometimes that which is done through ignorance does not deserve pardon, according to 1 Cor. 14:38: "If any man know not, he shall not be known." Therefore ignorance does not cause involuntariness.

Obj. 2: Further, every sin implies ignorance; according to Prov. 14:22: "They err, that work evil." If, therefore, ignorance causes involuntariness, it would follow that every sin is involuntary: which is opposed to the saying of Augustine, that "every sin is voluntary" (De Vera Relig. xiv).
