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

Reply Obj. 2: The good actions done by the hearers, result from the preacher's words, as an effect that flows from their very nature. Hence they redound to the merit of the preacher: especially when such is his intention.

Reply Obj. 3: The consequences for which that man is ordered to be punished, both follow from the nature of the cause, and are supposed to be foreseen. For this reason they are reckoned as punishable.

Reply Obj. 4: This argument would prove if irregularity were the result of the fault. But it is not the result of the fault, but of the fact, and of the obstacle to the reception of a sacrament. ________________________

SIXTH ARTICLE [I-II, Q. 20, Art. 6]

Whether One and the Same External Action Can Be Both Good and Evil?

Objection 1: It would seem that one and the same external action can be both good and evil. For "movement, if continuous, is one and the same" (Phys. v, 4). But one continuous movement can be both good and bad: for instance, a man may go to church continuously, intending at first vainglory, and afterwards the service of God. Therefore one and the same action can be both good and bad.

Obj. 2: Further, according to the Philosopher (Phys. iii, 3), action and passion are one act. But the passion may be good, as Christ's was; and the action evil, as that of the Jews. Therefore one and the same act can be both good and evil.

Obj. 3: Further, since a servant is an instrument, as it were, of his master, the servant's action is his master's, just as the action of a tool is the workman's action. But it may happen that the servant's action result from his master's good will, and is therefore good: and from the evil will of the servant, and is therefore evil. Therefore the same action can be both good and evil.

On the contrary, The same thing cannot be the subject of contraries. But good and evil are contraries. Therefore the same action cannot be both good and evil.

On the contrary, The same thing cannot be the subject of contraries. But good and evil are contraries. Therefore the same action cannot be both good and evil.

I answer that, Nothing hinders a thing from being one, in so far as it is in one genus, and manifold, in so far as it is referred to another genus. Thus a continuous surface is one, considered as in the genus of quantity; and yet it is manifold, considered as to the genus of color, if it be partly white, and partly black. And accordingly, nothing hinders an action from being one, considered in the natural order; whereas it is not one, considered in the moral order; and vice versa, as we have stated above (A. 3, ad 1; Q. 18, A. 7, ad 1). For continuous walking is one action, considered in the natural order: but it may resolve itself into many actions, considered in the moral order, if a change take place in the walker's will, for the will is the principle of moral actions. If therefore we consider one action in the moral order, it is impossible for it to be morally both good and evil. Whereas if it be one as to natural and not moral unity, it can be both good and evil.

Reply Obj. 1: This continual movement which proceeds from various intentions, although it is one in the natural order, is not one in the point of moral unity.

Reply Obj. 2: Action and passion belong to the moral order, in so far as they are voluntary. And therefore in so far as they are voluntary in respect of wills that differ, they are two distinct things, and good can be in one of them while evil is in the other.

Reply Obj. 3: The action of the servant, in so far as it proceeds from the will of the servant, is not the master's action: but only in so far as it proceeds from the master's command. Wherefore the evil will of the servant does not make the action evil in this respect.

We have now to consider the consequences of human actions by reason of their goodness and malice: and under this head there are four points of inquiry:

(1) Whether a human action is right or sinful by reason of its being good or evil?

(2) Whether it thereby deserves praise or blame?

(3) Whether accordingly, it is meritorious or demeritorious?

(4) Whether it is accordingly meritorious or demeritorious before God? ________________________

FIRST ARTICLE [I-II, Q. 21, Art. 1]

Whether a Human Action Is Right or Sinful, in So Far As It Is Good or

Evil?

Objection 1: It seems that a human action is not right or sinful, in so far as it is good or evil. For "monsters are the sins of nature" (Phys. ii, 8). But monsters are not actions, but things engendered outside the order of nature. Now things that are produced according to art and reason imitate those that are produced according to nature (Phys. ii, 8). Therefore an action is not sinful by reason of its being inordinate and evil.

Obj. 2: Further, sin, as stated in Phys. ii, 8 occurs in nature and art, when the end intended by nature or art is not attained. But the goodness or malice of a human action depends, before all, on the intention of the end, and on its achievement. Therefore it seems that the malice of an action does not make it sinful.

Obj. 3: Further, if the malice of an action makes it sinful, it follows that wherever there is evil, there is sin. But this is false: since punishment is not a sin, although it is an evil. Therefore an action is not sinful by reason of its being evil.

On the contrary, As shown above (Q. 19, A. 4), the goodness of a human action depends principally on the Eternal Law: and consequently its malice consists in its being in disaccord with the Eternal Law. But this is the very nature of sin; for Augustine says (Contra Faust. xxii, 27) that "sin is a word, deed, or desire, in opposition to the Eternal Law." Therefore a human action is sinful by reason of its being evil.

I answer that, Evil is more comprehensive than sin, as also is good than right. For every privation of good, in whatever subject, is an evil: whereas sin consists properly in an action done for a certain end, and lacking due order to that end. Now the due order to an end is measured by some rule. In things that act according to nature, this rule is the natural force that inclines them to that end. When therefore an action proceeds from a natural force, in accord with the natural inclination to an end, then the action is said to be right: since the mean does not exceed its limits, viz. the action does not swerve from the order of its active principle to the end. But when an action strays from this rectitude, it comes under the notion of sin.

Now in those things that are done by the will, the proximate rule is the human reason, while the supreme rule is the Eternal Law. When, therefore, a human action tends to the end, according to the order of reason and of the Eternal Law, then that action is right: but when it turns aside from that rectitude, then it is said to be a sin. Now it is evident from what has been said (Q. 19, AA. 3, 4) that every voluntary action that turns aside from the order of reason and of the Eternal Law, is evil, and that every good action is in accord with reason and the Eternal Law. Hence it follows that a human action is right or sinful by reason of its being good or evil.

Reply Obj. 1: Monsters are called sins, inasmuch as they result from a sin in nature's action.

Reply Obj. 2: The end is twofold; the last end, and the proximate end. In the sin of nature, the action does indeed fail in respect of the last end, which is the perfection of the thing generated; but it does not fail in respect of any proximate end whatever; since when nature works it forms something. In like manner, the sin of the will always fails as regards the last end intended, because no voluntary evil action can be ordained to happiness, which is the last end: and yet it does not fail in respect of some proximate end: intended and achieved by the will. Wherefore also, since the very intention of this end is ordained to the last end, this same intention may be right or sinful.
