Of the Good and Evil of Human Acts, in General

Of the Good and Evil of Human Acts, in General — St. Thomas Aquinas asks: Whether every human action is good, or are there evil actions?; Whether the good or evil of a man's action is derived from its object?; Whether man's action is good or evil from a circumstance?; Whether a human action is good or evil from its end?; Whether a human action is good or evil in its species?; Whether an action has the species of good or evil from its end?; Whether the species derived from the end is contained under the species derived from the object, as under its genus, or conversely?; Whether any action is indifferent in its species?; Whether an individual action can be indifferent?; Whether a circumstance places a moral action in the species of good or evil?; Whether every circumstance that makes an action better or worse, places a moral action in a species of good or evil?.

We must now consider the good and evil of human acts. First, how a human act is good or evil; secondly, what results from the good or evil of a human act, as merit or demerit, sin and guilt.

Under the first head there will be a threefold consideration: the first will be of the good and evil of human acts, in general; the second, of the good and evil of internal acts; the third, of the good and evil of external acts.

Concerning the first there are eleven points of inquiry:

Article 1: Whether every human action is good, or are there evil actions?

Our Lord said (Jn. 3:20): "Every one that doth evil, hateth the light." Therefore some actions of man are evil.

We must speak of good and evil in actions as of good and evil in things: because such as everything is, such is the act that it produces. Now in things, each one has so much good as it has being: since good and being are convertible, as was stated in the . But God alone has the whole plenitude of His Being in a certain unity: whereas every other thing has its proper fulness of being in a certain multiplicity. Wherefore it happens with some things, that they have being in some respect, and yet they are lacking in the fulness of being due to them. Thus the fulness of human being requires a compound of soul and body, having all the powers and instruments of knowledge and movement: wherefore if any man be lacking in any of these, he is lacking in something due to the fulness of his being. So that as much as he has of being, so much has he of goodness: while so far as he is lacking in goodness, and is said to be evil: thus a blind man is possessed of goodness inasmuch as he lives; and of evil, inasmuch as he lacks sight. That, however, which has nothing of being or goodness, could not be said to be either evil or good. But since this same fulness of being is of the very essence of good, if a thing be lacking in its due fulness of being, it is not said to be good simply, but in a certain respect, inasmuch as it is a being; although it can be called a being simply, and a non-being in a certain respect, as was stated in the . We must therefore say that every action has goodness, in so far as it has being; whereas it is lacking in goodness, in so far as it is lacking in something that is due to its fulness of being; and thus it is said to be evil: for instance if it lacks the quantity determined by reason, or its due place, or something of the kind.

Article 2: Whether the good or evil of a man's action is derived from its object?

It is written (Osee 9:10): "They became abominable as those things which they loved." Now man becomes abominable to God on account of the malice of his action. Therefore the malice of his action is according to the evil objects that man loves. And the same applies to the goodness of his action.

as stated above () the good or evil of an action, as of other things, depends on its fulness of being or its lack of that fulness. Now the first thing that belongs to the fulness of being seems to be that which gives a thing its species. And just as a natural thing has its species from its form, so an action has its species from its object, as movement from its term. And therefore just as the primary goodness of a natural thing is derived from its form, which gives it its species, so the primary goodness of a moral action is derived from its suitable object: hence some call such an action "good in its genus"; for instance, "to make use of what is one's own." And just as, in natural things, the primary evil is when a generated thing does not realize its specific form (for instance, if instead of a man, something else be generated); so the primary evil in moral actions is that which is from the object, for instance, "to take what belongs to another." And this action is said to be "evil in its genus," genus here standing for species, just as we apply the term "mankind" to the whole human species.

Article 3: Whether man's action is good or evil from a circumstance?

the Philosopher says (Ethic. ii, 3) that a virtuous man acts as he should, and when he should, and so on in respect of the other circumstances. Therefore, on the other hand, the vicious man, in the matter of each vice, acts when he should not, or where he should not, and so on with the other circumstances. Therefore human actions are good or evil according to circumstances.

In natural things, it is to be noted that the whole fulness of perfection due to a thing, is not from the mere substantial form, that gives it its species; since a thing derives much from supervening accidents, as man does from shape, color, and the like; and if any one of these accidents be out of due proportion, evil is the result. So it is with action. For the plenitude of its goodness does not consist wholly in its species, but also in certain additions which accrue to it by reason of certain accidents: and such are its due circumstances. Wherefore if something be wanting that is requisite as a due circumstance the action will be evil.

Article 4: Whether a human action is good or evil from its end?

Boethius says (De Differ. Topic. ii) that "if the end is good, the thing is good, and if the end be evil, the thing also is evil."

The disposition of things as to goodness is the same as their disposition as to being. Now in some things the being does not depend on another, and in these it suffices to consider their being absolutely. But there are things the being of which depends on something else, and hence in their regard we must consider their being in its relation to the cause on which it depends. Now just as the being of a thing depends on the agent, and the form, so the goodness of a thing depends on its end. Hence in the Divine Persons, Whose goodness does not depend on another, the measure of goodness is not taken from the end. Whereas human actions, and other things, the goodness of which depends on something else, have a measure of goodness from the end on which they depend, besides that goodness which is in them absolutely.

Accordingly a fourfold goodness may be considered in a human action. First, that which, as an action, it derives from its genus; because as much as it has of action and being so much has it of goodness, as stated above (). Secondly, it has goodness according to its species; which is derived from its suitable object. Thirdly, it has goodness from its circumstances, in respect, as it were, of its accidents. Fourthly, it has goodness from its end, to which it is compared as to the cause of its goodness.

Article 5: Whether a human action is good or evil in its species?

According to the Philosopher (Ethic ii. 1) "like habits produce like actions." But a good and a bad habit differ in species, as liberality and prodigality. Therefore also good and bad actions differ in species.

Every action derives its species from its object, as stated above (). Hence it follows that a difference of object causes a difference of species in actions. Now, it must be observed that a difference of objects causes a difference of species in actions, according as the latter are referred to one active principle, which does not cause a difference in actions, according as they are referred to another active principle. Because nothing accidental constitutes a species, but only that which is essential; and a difference of object may be essential in reference to one active principle, and accidental in reference to another. Thus to know color and to know sound, differ essentially in reference to sense, but not in reference to the intellect.

Now in human actions, good and evil are predicated in reference to the reason; because as Dionysius says (Div. Nom. iv), "the good of man is to be in accordance with reason," and evil is "to be against reason." For that is good for a thing which suits it in regard to its form; and evil, that which is against the order of its form. It is therefore evident that the difference of good and evil considered in reference to the object is an essential difference in relation to reason; that is to say, according as the object is suitable or unsuitable to reason. Now certain actions are called human or moral, inasmuch as they proceed from the reason. Consequently it is evident that good and evil diversify the species in human actions; since essential differences cause a difference of species.

Article 6: Whether an action has the species of good or evil from its end?

It has been shown above () that human actions derive their species from the end. Therefore good and evil in respect of the end diversify the species of actions.

Certain actions are called human, inasmuch as they are voluntary, as stated above (). Now, in a voluntary action, there is a twofold action, viz. the interior action of the will, and the external action: and each of these actions has its object. The end is properly the object of the interior act of the will: while the object of the external action, is that on which the action is brought to bear. Therefore just as the external action takes its species from the object on which it bears; so the interior act of the will takes its species from the end, as from its own proper object.

Now that which is on the part of the will is formal in regard to that which is on the part of the external action: because the will uses the limbs to act as instruments; nor have external actions any measure of morality, save in so far as they are voluntary. Consequently the species of a human act is considered formally with regard to the end, but materially with regard to the object of the external action. Hence the Philosopher says (Ethic. v, 2) that "he who steals that he may commit adultery, is strictly speaking, more adulterer than thief."

Article 7: Whether the species derived from the end is contained under the species derived from the object, as under its genus, or conversely?

Each genus has its determinate differences. But an action of one same species on the part of its object, can be ordained to an infinite number of ends: for instance, theft can be ordained to an infinite number of good and bad ends. Therefore the species derived from the end is not contained under the species derived from the object, as under its genus.

The object of the external act can stand in a twofold relation to the end of the will: first, as being of itself ordained thereto; thus to fight well is of itself ordained to victory; secondly, as being ordained thereto accidentally; thus to take what belongs to another is ordained accidentally to the giving of alms. Now the differences that divide a genus, and constitute the species of that genus, must, as the Philosopher says (Metaph. vii, 12), divide that genus essentially: and if they divide it accidentally, the division is incorrect: as, if one were to say: "Animals are divided into rational and irrational; and the irrational into animals with wings, and animals without wings"; for "winged" and "wingless" are not essential determinations of the irrational being. But the following division would be correct: "Some animals have feet, some have no feet: and of those that have feet, some have two feet, some four, some many": because the latter division is an essential determination of the former. Accordingly when the object is not of itself ordained to the end, the specific difference derived from the object is not an essential determination of the species derived from the end, nor is the reverse the case. Wherefore one of these species is not under the other; but then the moral action is contained under two species that are disparate, as it were. Consequently we say that he that commits theft for the sake of adultery, is guilty of a twofold malice in one action. On the other hand, if the object be of itself ordained to the end, one of these differences is an essential determination of the other. Wherefore one of these species will be contained under the other.

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.

Article 8: Whether any action is indifferent in its species?

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.

As stated above (), 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.

Article 9: Whether an individual action can be indifferent?

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" (Mat. 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.

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 (), 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.

If, however, it does not proceed from deliberate reason, but from some act of the imagination, as when a man strokes his beard, or moves his hand or foot; such an action, properly speaking, is not moral or human; since this depends on the reason. Hence it will be indifferent, as standing apart from the genus of moral actions.

Article 10: Whether a circumstance places a moral action in the species of good or evil?

Place is a circumstance. But place makes a moral action to be in a certain species of evil; for theft of a thing from a holy place is a sacrilege. Therefore a circumstance makes a moral action to be specifically good or bad.

Just as the species of natural things are constituted by their natural forms, so the species of moral actions are constituted by forms as conceived by the reason, as is evident from what was said above (). But since nature is determinate to one thing, nor can a process of nature go on to infinity, there must needs be some ultimate form, giving a specific difference, after which no further specific difference is possible. Hence it is that in natural things, that which is accidental to a thing, cannot be taken as a difference constituting the species. But the process of reason is not fixed to one particular term, for at any point it can still proceed further. And consequently that which, in one action, is taken as a circumstance added to the object that specifies the action, can again be taken by the directing reason, as the principal condition of the object that determines the action's species. Thus to appropriate another's property is specified by reason of the property being "another's," and in this respect it is placed in the species of theft; and if we consider that action also in its bearing on place or time, then this will be an additional circumstance. But since the reason can direct as to place, time, and the like, it may happen that the condition as to place, in relation to the object, is considered as being in disaccord with reason: for instance, reason forbids damage to be done to a holy place. Consequently to steal from a holy place has an additional repugnance to the order of reason. And thus place, which was first of all considered as a circumstance, is considered here as the principal condition of the object, and as itself repugnant to reason. And in this way, whenever a circumstance has a special relation to reason, either for or against, it must needs specify the moral action whether good or bad.

Article 11: Whether every circumstance that makes an action better or worse, places a moral action in a species of good or evil?

More and less do not change a species. But more and less is a circumstance of additional goodness or malice. Therefore not every circumstance that makes a moral action better or worse, places it in a species of good or evil.

As stated above (), a circumstance gives the species of good or evil to a moral action, in so far as it regards a special order of reason. Now it happens sometimes that a circumstance does not regard a special order of reason in respect of good or evil, except on the supposition of another previous circumstance, from which the moral action takes its species of good or evil. Thus to take something in a large or small quantity, does not regard the order of reason in respect of good or evil, except a certain other condition be presupposed, from which the action takes its malice or goodness; for instance, if what is taken belongs to another, which makes the action to be discordant with reason. Wherefore to take what belongs to another in a large or small quantity, does not change the species of the sin. Nevertheless it can aggravate or diminish the sin. The same applies to other evil or good actions. Consequently not every circumstance that makes a moral action better or worse, changes its species.
