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

It remains to be considered which of the two is contained under the other. In order to make this clear, we must first of all observe that the more particular the form is from which a difference is taken, the more specific is the difference. Secondly, that the more universal an agent is, the more universal a form does it cause. Thirdly, that the more remote an end is, the more universal the agent to which it corresponds; thus victory, which is the last end of the army, is the end intended by the commander in chief; while the right ordering of this or that regiment is the end intended by one of the lower officers. From all this it follows that the specific difference derived from the end, is more general; and that the difference derived from an object which of itself is ordained to that end, is a specific difference in relation to the former. For the will, the proper object of which is the end, is the universal mover in respect of all the powers of the soul, the proper objects of which are the objects of their particular acts.

Reply Obj. 1: One and the same thing, considered in its substance, cannot be in two species, one of which is not subordinate to the other. But in respect of those things which are superadded to the substance, one thing can be contained under different species. Thus one and the same fruit, as to its color, is contained under one species, i.e. a white thing: and, as to its perfume, under the species of sweet-smelling things. In like manner an action which, as to its substance, is in one natural species, considered in respect to the moral conditions that are added to it, can belong to two species, as stated above (Q. 1, A. 3, ad 3).

Reply Obj. 2: The end is last in execution; but first in the intention of the reason, in regard to which moral actions receive their species.

Reply Obj. 3: Difference is compared to genus as form to matter, inasmuch as it actualizes the genus. On the other hand, the genus is considered as more formal than the species, inasmuch as it is something more absolute and less contracted. Wherefore also the parts of a definition are reduced to the genus of formal cause, as is stated in Phys. ii, 3. And in this sense the genus is the formal cause of the species; and so much the more formal, as it is more universal. ________________________

Whether Any Action Is Indifferent in Its Species?

Objection 1: It would seem that no action is indifferent in its species. For evil is the privation of good, according to Augustine (Enchiridion xi). But privation and habit are immediate contraries, according to the Philosopher (Categor. viii). Therefore there is not such thing as an action that is indifferent in its species, as though it were between good and evil.

Obj. 2: Further, human actions derive their species from their end or object, as stated above (A. 6; Q. 1, A. 3). But every end and every object is either good or bad. Therefore every human action is good or evil according to its species. None, therefore, is indifferent in its species.

Obj. 3: Further, as stated above (A. 1), an action is said to be good, when it has its due complement of goodness; and evil, when it lacks that complement. But every action must needs either have the entire plenitude of its goodness, or lack it in some respect. Therefore every action must needs be either good or bad in its species, and none is indifferent.

On the contrary, Augustine says (De Serm. Dom. in Monte ii, 18) that "there are certain deeds of a middle kind, which can be done with a good or evil mind, of which it is rash to form a judgment." Therefore some actions are indifferent according to their species.

I answer that, As stated above (AA. 2, 5), every action takes its species from its object; while human action, which is called moral, takes its species from the object, in relation to the principle of human actions, which is the reason. Wherefore if the object of an action includes something in accord with the order of reason, it will be a good action according to its species; for instance, to give alms to a person in want. On the other hand, if it includes something repugnant to the order of reason, it will be an evil act according to its species; for instance, to steal, which is to appropriate what belongs to another. But it may happen that the object of an action does not include something pertaining to the order of reason; for instance, to pick up a straw from the ground, to walk in the fields, and the like: and such actions are indifferent according to their species.

Reply Obj. 1: Privation is twofold. One is privation "as a result" ( privatum esse ), and this leaves nothing, but takes all away: thus blindness takes away sight altogether; darkness, light; and death, life. Between this privation and the contrary habit, there can be no medium in respect of the proper subject. The other is privation "in process" ( privari ): thus sickness is privation of health; not that it takes health away altogether, but that it is a kind of road to the entire loss of health, occasioned by death. And since this sort of privation leaves something, it is not always the immediate contrary of the opposite habit. In this way evil is a privation of good, as Simplicius says in his commentary on the Categories: because it does not take away all good, but leaves some. Consequently there can be something between good and evil.

Reply Obj. 2: Every object or end has some goodness or malice, at least natural to it: but this does not imply moral goodness or malice, which is considered in relation to the reason, as stated above. And it is of this that we are here treating.

Reply Obj. 3: Not everything belonging to an action belongs also to its species. Wherefore although an action's specific nature may not contain all that belongs to the full complement of its goodness, it is not therefore an action specifically bad; nor is it specifically good. Thus a man in regard to his species is neither virtuous nor wicked. ________________________

NINTH ARTICLE [I-II, Q. 18, Art. 9]

Whether an Individual Action Can Be Indifferent?

Objection 1: It would seem that an individual action can be indifferent. For there is no species that does not, or cannot, contain an individual. But an action can be indifferent in its species, as stated above (A. 8). Therefore an individual action can be indifferent.

Obj. 2: Further, individual actions cause like habits, as stated in Ethic. ii, 1. But a habit can be indifferent: for the Philosopher says (Ethic. iv, 1) that those who are of an even temper and prodigal disposition are not evil; and yet it is evident that they are not good, since they depart from virtue; and thus they are indifferent in respect of a habit. Therefore some individual actions are indifferent.

Obj. 3: Further, moral good belongs to virtue, while moral evil belongs to vice. But it happens sometimes that a man fails to ordain a specifically indifferent action to a vicious or virtuous end. Therefore an individual action may happen to be indifferent.

On the contrary, Gregory says in a homily (vi in Evang.): "An idle word is one that lacks either the usefulness of rectitude or the motive of just necessity or pious utility." But an idle word is an evil, because "men . . . shall render an account of it in the day of judgment" (Matt. 12:36): while if it does not lack the motive of just necessity or pious utility, it is good. Therefore every word is either good or bad. For the same reason every other action is either good or bad. Therefore no individual action is indifferent.

I answer that, It sometimes happens that an action is indifferent in its species, but considered in the individual it is good or evil. And the reason of this is because a moral action, as stated above (A. 3), derives its goodness not only from its object, whence it takes its species; but also from the circumstances, which are its accidents, as it were; just as something belongs to a man by reason of his individual accidents, which does not belong to him by reason of his species. And every individual action must needs have some circumstance that makes it good or bad, at least in respect of the intention of the end. For since it belongs to the reason to direct; if an action that proceeds from deliberate reason be not directed to the due end, it is, by that fact alone, repugnant to reason, and has the character of evil. But if it be directed to a due end, it is in accord with reason; wherefore it has the character of good. Now it must needs be either directed or not directed to a due end. Consequently every human action that proceeds from deliberate reason, if it be considered in the individual, must be good or bad.
