Of Consent, Which Is an Act of the Will in Regard to the Means

Of Consent, Which Is an Act of the Will in Regard to the Means — St. Thomas Aquinas asks: Whether consent is an act of the appetitive or of the apprehensive power?; Whether consent is to be found in irrational animals?; Whether consent is directed to the end or to the means?; Whether consent to the act belongs only to the higher part of the soul?.

We must now consider consent; concerning which there are four points of inquiry:

Article 1: Whether consent is an act of the appetitive or of the apprehensive power?

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.

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.

Article 2: Whether consent is to be found in irrational animals?

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.

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.

Article 3: Whether consent is directed to the end or to the means?

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.

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.

Article 4: Whether consent to the act belongs only to the higher part of the soul?

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."

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 ().
