Summa Theologica Part II (Pars Prima Secundae) Part 109

Reply Obj. 2: "Good happens in one way, evil in all manner of ways,"

as Dionysius says (Div. Nom. iv): so that to one virtue many vices are contrary. Consequently we must not be surprised if the works of the flesh are more numerous than the fruits of the spirit.

The Reply to the Third Objection is clear from what has been said.

EVIL HABITS, i.e. VICES AND SINS (QQ. 71-89) ________________________

QUESTION 71

OF VICE AND SIN CONSIDERED IN THEMSELVES (In Six Articles)

We have in the next place to consider vice and sin: about which six points have to be considered: (1) Vice and sin considered in themselves; (2) their distinction; (3) their comparison with one another; (4) the subject of sin; (5) the cause of sin; (6) the effect of sin.

Under the first head there are six points of inquiry:

(1) Whether vice is contrary to virtue?

(2) Whether vice is contrary to nature?

(3) Which is worse, a vice or a vicious act?

(4) Whether a vicious act is compatible with virtue?

(5) Whether every sin includes action?

(6) Of the definition of sin proposed by Augustine (Contra Faust.

xxii): "Sin is a word, deed, or desire against the eternal law."

FIRST ARTICLE [I-II, Q. 71, Art. 1]

Whether Vice Is Contrary to Virtue?

Objection 1: It would seem that vice is not contrary to virtue. For one thing has one contrary, as proved in _Metaph._ x, text. 17. Now sin and malice are contrary to virtue. Therefore vice is not contrary to it: since vice applies also to undue disposition of bodily members or of any things whatever.

Obj. 2: Further, virtue denotes a certain perfection of power. But vice does not denote anything relative to power. Therefore vice is not contrary to virtue.

Obj. 3: Further, Cicero (De Quaest. Tusc. iv) says that "virtue is the soul's health." Now sickness or disease, rather than vice, is opposed to health. Therefore vice is not contrary to virtue.

_On the contrary,_ Augustine says (De Perfect. Just.i.t. ii) that "vice is a quality in respect of which the soul is evil." But "virtue is a quality which makes its subject good," as was shown above (Q. 55, AA.

3, 4). Therefore vice is contrary to virtue.

_I answer that,_ Two things may be considered in virtue--the essence of virtue, and that to which virtue is ordained. In the essence of virtue we may consider something directly, and we may consider something consequently. Virtue implies _directly_ a disposition whereby the subject is well disposed according to the mode of its nature: wherefore the Philosopher says (Phys. vii, text. 17) that "virtue is a disposition of a perfect thing to that which is best; and by perfect I mean that which is disposed according to its nature." That which virtue implies _consequently_ is that it is a kind of goodness: because the goodness of a thing consists in its being well disposed according to the mode of its nature. That to which virtue is directed is a good act, as was shown above (Q. 56, A. 3).

Accordingly three things are found to be contrary to virtue. One of these is _sin,_ which is opposed to virtue in respect of that to which virtue is ordained: since, properly speaking, sin denotes an inordinate act; even as an act of virtue is an ordinate and due act: in respect of that which virtue implies consequently, viz. that it is a kind of goodness, the contrary of virtue is _malice_: while in respect of that which belongs to the essence of virtue directly, its contrary is _vice_: because the vice of a thing seems to consist in its not being disposed in a way befitting its nature: hence Augustine says (De Lib. Arb. iii): "Whatever is lacking for a thing's natural perfection may be called a vice."

Reply Obj. 1: These three things are contrary to virtue, but not in the same respect: for sin is opposed to virtue, according as the latter is productive of a good work; malice, according as virtue is a kind of goodness; while vice is opposed to virtue properly as such.

Reply Obj. 2: Virtue implies not only perfection of power, the principle of action; but also the due disposition of its subject. The reason for this is because a thing operates according as it is in act: so that a thing needs to be well disposed if it has to produce a good work. It is in this respect that vice is contrary to virtue.

Reply Obj. 3: As Cicero says (De Quaest. Tusc. iv), "disease and sickness are vicious qualities," for in speaking of the body he calls it disease "when the whole body is infected," for instance, with fever or the like; he calls it sickness "when the disease is attended with weakness"; and vice "when the parts of the body are not well compacted together." And although at times there may be disease in the body without sickness, for instance, when a man has a hidden complaint without being hindered outwardly from his wonted occupations; "yet, in the soul," as he says, "these two things are indistinguishable, except in thought." For whenever a man is ill-disposed inwardly, through some inordinate affection, he is rendered thereby unfit for fulfilling his duties: since "a tree is known by its fruit," i.e. man by his works, according to Matt. 12:33.

But "vice of the soul," as Cicero says (De Quaest. Tusc. iv), "is a habit or affection of the soul discordant and inconsistent with itself through life": and this is to be found even without disease and sickness, e.g. when a man sins from weakness or pa.s.sion.

Consequently vice is of wider extent than sickness or disease; even as virtue extends to more things than health; for health itself is reckoned a kind of virtue (Phys. vii, text. 17). Consequently vice is reckoned as contrary to virtue, more fittingly than sickness or disease.

SECOND ARTICLE [I-II, Q. 71, Art. 2]

Whether Vice Is Contrary to Nature?

Objection 1: It would seem that vice is not contrary to nature.

Because vice is contrary to virtue, as stated above (A. 1). Now virtue is in us, not by nature but by infusion or habituation, as stated above (Q. 63, AA. 1, 2, 3). Therefore vice is not contrary to nature.

Obj. 2: Further, it is impossible to become habituated to that which is contrary to nature: thus "a stone never becomes habituated to upward movement" (Ethic. ii, 1). But some men become habituated to vice. Therefore vice is not contrary to nature.

Obj. 3: Further, anything contrary to a nature, is not found in the greater number of individuals possessed of that nature. Now vice is found in the greater number of men; for it is written (Matt. 7:13): "Broad is the way that leadeth to destruction, and many there are who go in thereat." Therefore vice is not contrary to nature.

Obj. 4: Further, sin is compared to vice, as act to habit, as stated above (A. 1). Now sin is defined as "a word, deed, or desire, contrary to the Law of G.o.d," as Augustine shows (Contra Faust. xxii, 27). But the Law of G.o.d is above nature. Therefore we should say that vice is contrary to the Law, rather than to nature.

_On the contrary,_ Augustine says (De Lib. Arb. iii, 13): "Every vice, simply because it is a vice, is contrary to nature."

_I answer that,_ As stated above (A. 1), vice is contrary to virtue.

Now the virtue of a thing consists in its being well disposed in a manner befitting its nature, as stated above (A. 1). Hence the vice of any thing consists in its being disposed in a manner not befitting its nature, and for this reason is that thing "vituperated," which word is derived from "vice" according to Augustine (De Lib. Arb. iii, 14).

But it must be observed that the nature of a thing is chiefly the form from which that thing derives its species. Now man derives his species from his rational soul: and consequently whatever is contrary to the order of reason is, properly speaking, contrary to the nature of man, as man; while whatever is in accord with reason, is in accord with the nature of man, as man. Now "man's good is to be in accord with reason, and his evil is to be against reason," as Dionysius states (Div. Nom. iv). Therefore human virtue, which makes a man good, and his work good, is in accord with man's nature, for as much as it accords with his reason: while vice is contrary to man's nature, in so far as it is contrary to the order of reason.

Reply Obj. 1: Although the virtues are not caused by nature as regards their perfection of being, yet they incline us to that which accords with reason, i.e. with the order of reason. For Cicero says (De Inv. Rhet. ii) that "virtue is a habit in accord with reason, like a second nature": and it is in this sense that virtue is said to be in accord with nature, and on the other hand that vice is contrary to nature.

Reply Obj. 2: The Philosopher is speaking there of a thing being against nature, in so far as "being against nature" is contrary to "being from nature": and not in so far as "being against nature" is contrary to "being in accord with nature," in which latter sense virtues are said to be in accord with nature, in as much as they incline us to that which is suitable to nature.

Reply Obj. 3: There is a twofold nature in man, rational nature, and the sensitive nature. And since it is through the operation of his senses that man accomplishes acts of reason, hence there are more who follow the inclinations of the sensitive nature, than who follow the order of reason: because more reach the beginning of a business than achieve its completion. Now the presence of vices and sins in man is owing to the fact that he follows the inclination of his sensitive nature against the order of his reason.

Reply Obj. 4: Whatever is irregular in a work of art, is unnatural to the art which produced that work. Now the eternal law is compared to the order of human reason, as art to a work of art. Therefore it amounts to the same that vice and sin are against the order of human reason, and that they are contrary to the eternal law. Hence Augustine says (De Lib. Arb. iii, 6) that "every nature, as such, is from G.o.d; and is a vicious nature, in so far as it fails from the Divine art whereby it was made."

THIRD ARTICLE [I-II, Q. 71, Art. 3]

Whether Vice Is Worse Than a Vicious Act?

Objection 1: It would seem that vice, i.e. a bad habit, is worse than a sin, i.e. a bad act. For, as the more lasting a good is, the better it is, so the longer an evil lasts, the worse it is. Now a vicious habit is more lasting than vicious acts, that pa.s.s forthwith.

Therefore a vicious habit is worse than a vicious act.

Obj. 2: Further, several evils are more to be shunned than one. But a bad habit is virtually the cause of many bad acts. Therefore a vicious habit is worse than a vicious act.

Obj. 3: Further, a cause is more potent than its effect. But a habit produces its actions both as to their goodness and as to their badness. Therefore a habit is more potent than its act, both in goodness and in badness.

_On the contrary,_ A man is justly punished for a vicious act; but not for a vicious habit, so long as no act ensues. Therefore a vicious action is worse than a vicious habit.

_I answer that,_ A habit stands midway between power and act. Now it is evident that both in good and in evil, act precedes power, as stated in _Metaph._ ix, 19. For it is better to do well than to be able to do well, and in like manner, it is more blameworthy to do evil, than to be able to do evil: whence it also follows that both in goodness and in badness, habit stands midway between power and act, so that, to wit, even as a good or evil habit stands above the corresponding power in goodness or in badness, so does it stand below the corresponding act. This is also made clear from the fact that a habit is not called good or bad, save in so far as it induces to a good or bad act: wherefore a habit is called good or bad by reason of the goodness or badness of its act: so that an act surpa.s.ses its habit in goodness or badness, since "the cause of a thing being such, is yet more so."
