Of the Cardinal Virtues

Of the Cardinal Virtues — St. Thomas Aquinas asks: Whether the moral virtues should be called cardinal or principal virtues?; Whether there are four cardinal virtues?; Whether any other virtues should be called principal rather than these?; Whether the four cardinal virtues differ from one another?; Whether the cardinal virtues are fittingly divided into social virtues, perfecting, perfect, and exemplar virtues?.

We must now consider the cardinal virtues: under which head there are five points of inquiry:

Article 1: Whether the moral virtues should be called cardinal or principal virtues?

Ambrose in explaining the words, "Blessed are the poor in spirit" (Lk. 6:20) says: "We know that there are four cardinal virtues, viz. temperance, justice, prudence, and fortitude." But these are moral virtues. Therefore the moral virtues are cardinal virtues.

When we speak of virtue simply, we are understood to speak of human virtue. Now human virtue, as stated above (), is one that answers to the perfect idea of virtue, which requires rectitude of the appetite: for such like virtue not only confers the faculty of doing well, but also causes the good deed done. On the other hand, the name virtue is applied to one that answers imperfectly to the idea of virtue, and does not require rectitude of the appetite: because it merely confers the faculty of doing well without causing the good deed to be done. Now it is evident that the perfect is principal as compared to the imperfect: and so those virtues which imply rectitude of the appetite are called principal virtues. Such are the moral virtues, and prudence alone, of the intellectual virtues, for it is also something of a moral virtue, as was clearly shown above (). Consequently, those virtues which are called principal or cardinal are fittingly placed among the moral virtues.

Article 2: Whether there are four cardinal virtues?

Gregory says (Moral. ii): "The entire structure of good works is built on four virtues."

Things may be numbered either in respect of their formal principles, or according to the subjects in which they are: and either way we find that there are four cardinal virtues.

For the formal principle of the virtue of which we speak now is good as defined by reason; which good is considered in two ways. First, as existing in the very act of reason: and thus we have one principal virtue, called "Prudence." Secondly, according as the reason puts its order into something else; either into operations, and then we have "Justice"; or into passions, and then we need two virtues. For the need of putting the order of reason into the passions is due to their thwarting reason: and this occurs in two ways. First, by the passions inciting to something against reason, and then the passions need a curb, which we call "Temperance." Secondly, by the passions withdrawing us from following the dictate of reason, e.g. through fear of danger or toil: and then man needs to be strengthened for that which reason dictates, lest he turn back; and to this end there is "Fortitude."

In like manner, we find the same number if we consider the subjects of virtue. For there are four subjects of the virtue we speak of now: viz. the power which is rational in its essence, and this is perfected by "Prudence"; and that which is rational by participation, and is threefold, the will, subject of "Justice," the concupiscible faculty, subject of "Temperance," and the irascible faculty, subject of "Fortitude."

Article 3: Whether any other virtues should be called principal rather than these?

Cicero reduces all other virtues to these four (De Invent. Rhet. ii).

As stated above (), these four are reckoned as cardinal virtues, in respect of the four formal principles of virtue as we understand it now. These principles are found chiefly in certain acts and passions. Thus the good which exists in the act of reason, is found chiefly in reason's command, but not in its counsel or its judgment, as stated above (). Again, good as defined by reason and put into our operations as something right and due, is found chiefly in commutations and distributions in respect of another person, and on a basis of equality. The good of curbing the passions is found chiefly in those passions which are most difficult to curb, viz. in the pleasures of touch. The good of being firm in holding to the good defined by reason, against the impulse of passion, is found chiefly in perils of death, which are most difficult to withstand.

Accordingly the above four virtues may be considered in two ways. First, in respect of their common formal principles. In this way they are called principal, being general, as it were, in comparison with all the virtues: so that, for instance, any virtue that causes good in reason's act of consideration, may be called prudence; every virtue that causes the good of right and due in operation, be called justice; every virtue that curbs and represses the passions, be called temperance; and every virtue that strengthens the mind against any passions whatever, be called fortitude. Many, both holy doctors, as also philosophers, speak about these virtues in this sense: and in this way the other virtues are contained under them. Wherefore all the objections fail.

Secondly, they may be considered in point of their being denominated, each one from that which is foremost in its respective matter, and thus they are specific virtues, condivided with the others. Yet they are called principal in comparison with the other virtues, on account of the importance of their matter: so that prudence is the virtue which commands; justice, the virtue which is about due actions between equals; temperance, the virtue which suppresses desires for the pleasures of touch; and fortitude, the virtue which strengthens against dangers of death. Thus again do the objections fail: because the other virtues may be principal in some other way, but these are called principal by reason of their matter, as stated above.

Article 4: Whether the four cardinal virtues differ from one another?

Augustine says (De Moribus Eccl. xi) that "there are four virtues, corresponding to the various emotions of love," and he applies this to the four virtues mentioned above. Therefore the same four virtues are distinct from one another.

As stated above (), these four virtues are understood differently by various writers. For some take them as signifying certain general conditions of the human mind, to be found in all the virtues: so that, to wit, prudence is merely a certain rectitude of discretion in any actions or matters whatever; justice, a certain rectitude of the mind, whereby a man does what he ought in any matters; temperance, a disposition of the mind, moderating any passions or operations, so as to keep them within bounds; and fortitude, a disposition whereby the soul is strengthened for that which is in accord with reason, against any assaults of the passions, or the toil involved by any operations. To distinguish these four virtues in this way does not imply that justice, temperance and fortitude are distinct virtuous habits: because it is fitting that every moral virtue, from the fact that it is a "habit," should be accompanied by a certain firmness so as not to be moved by its contrary: and this, we have said, belongs to fortitude. Moreover, inasmuch as it is a "virtue," it is directed to good which involves the notion of right and due; and this, we have said, belongs to justice. Again, owing to the fact that it is a "moral virtue" partaking of reason, it observes the mode of reason in all things, and does not exceed its bounds, which has been stated to belong to temperance. It is only in the point of having discretion, which we ascribed to prudence, that there seems to be a distinction from the other three, inasmuch as discretion belongs essentially to reason; whereas the other three imply a certain share of reason by way of a kind of application (of reason) to passions or operations. According to the above explanation, then, prudence would be distinct from the other three virtues: but these would not be distinct from one another; for it is evident that one and the same virtue is both habit, and virtue, and moral virtue.

Others, however, with better reason, take these four virtues, according as they have their special determinate matter; each of its own matter, in which special commendation is given to that general condition from which the virtue's name is taken as stated above (). In this way it is clear that the aforesaid virtues are distinct habits, differentiated in respect of their diverse objects.

Article 5: Whether the cardinal virtues are fittingly divided into social virtues, perfecting, perfect, and exemplar virtues?

Macrobius says (Super Somn. Scip. 1): "Plotinus, together with Plato foremost among teachers of philosophy, says: 'The four kinds of virtue are fourfold: In the first place there are social* virtues; secondly, there are perfecting virtues [*Virtutes purgatoriae: literally meaning, cleansing virtues]; thirdly, there are perfect [*Virtutes purgati animi: literally, virtues of the clean soul] virtues; and fourthly, there are exemplar virtues.'" [*Cf. Chrysostom's fifteenth homily on St. Matthew, where he says: "The gentle, the modest, the merciful, the just man does not shut up his good deeds within himself . . . He that is clean of heart and peaceful, and suffers persecution for the sake of the truth, lives for the common weal."]

As Augustine says (De Moribus Eccl. vi), "the soul needs to follow something in order to give birth to virtue: this something is God: if we follow Him we shall live aright." Consequently the exemplar of human virtue must needs pre-exist in God, just as in Him pre-exist the types of all things. Accordingly virtue may be considered as existing originally in God, and thus we speak of "exemplar" virtues: so that in God the Divine Mind itself may be called prudence; while temperance is the turning of God's gaze on Himself, even as in us it is that which conforms the appetite to reason. God's fortitude is His unchangeableness; His justice is the observance of the Eternal Law in His works, as Plotinus states (Cf. Macrobius, Super Somn. Scip. 1).

Again, since man by his nature is a social [*See above note on Chrysostom] animal, these virtues, in so far as they are in him according to the condition of his nature, are called "social" virtues; since it is by reason of them that man behaves himself well in the conduct of human affairs. It is in this sense that we have been speaking of these virtues until now.

But since it behooves a man to do his utmost to strive onward even to Divine things, as even the Philosopher declares in Ethic. x, 7, and as Scripture often admonishes us---for instance: "Be ye . . . perfect, as your heavenly Father is perfect" (Mat. 5:48), we must needs place some virtues between the social or human virtues, and the exemplar virtues which are Divine. Now these virtues differ by reason of a difference of movement and term: so that some are virtues of men who are on their way and tending towards the Divine similitude; and these are called "perfecting" virtues. Thus prudence, by contemplating the things of God, counts as nothing all things of the world, and directs all the thoughts of the soul to God alone: temperance, so far as nature allows, neglects the needs of the body; fortitude prevents the soul from being afraid of neglecting the body and rising to heavenly things; and justice consists in the soul giving a whole-hearted consent to follow the way thus proposed. Besides these there are the virtues of those who have already attained to the Divine similitude: these are called the "perfect virtues." Thus prudence sees nought else but the things of God; temperance knows no earthly desires; fortitude has no knowledge of passion; and justice, by imitating the Divine Mind, is united thereto by an everlasting covenant. Such as the virtues attributed to the Blessed, or, in this life, to some who are at the summit of perfection.
