Reply Obj. 4: Those things to which the moral virtues incline, are as the principles of prudence: whereas the products of art are not the principles, but the matter of art. Now it is evident that, though reason may be right in one part of the matter, and not in another, yet in no way can it be called right reason, if it be deficient in any principle whatever. Thus, if a man be wrong about the principle, "A whole is greater than its part," he cannot acquire the science of geometry, because he must necessarily wander from the truth in his conclusion. Moreover, things done are related to one another, but not things made, as stated above (ad 3). Consequently the lack of prudence in one department of things to be done, would result in a deficiency affecting other things to be done: whereas this does not occur in things to be made.
^Q. 65 Art. 2: Whether moral virtues can be without charity?
Obj. 1: It would seem that moral virtues can be without charity. For it is stated in the Liber Sentent. Prosperi vii, that "every virtue save charity may be common to the good and bad." But "charity can be in none except the good," as stated in the same book. Therefore the other virtues can be had without charity.
Obj. 2: Further, moral virtues can be acquired by means of human acts, as stated in Ethic. ii, 1, 2, whereas charity cannot be had otherwise than by infusion, according to Rom. 5:5: "The charity of God is poured forth in our hearts by the Holy Ghost Who is given to us." Therefore it is possible to have the other virtues without charity.
Obj. 3: Further, the moral virtues are connected together, through depending on prudence. But charity does not depend on prudence; indeed, it surpasses prudence, according to Eph. 3:19: "The charity of Christ, which surpasseth all knowledge." Therefore the moral virtues are not connected with charity, and can be without it.
On the contrary, It is written (1 John 3:14): "He that loveth not, abideth in death." Now the spiritual life is perfected by the virtues, since it is "by them" that "we lead a good life," as Augustine states (De Lib. Arb. ii, 17, 19). Therefore they cannot be without the love of charity.
I answer that, As stated above (Q. 63, A. 2), it is possible by means of human works to acquire moral virtues, in so far as they produce good works that are directed to an end not surpassing the natural power of man: and when they are acquired thus, they can be without charity, even as they were in many of the Gentiles. But in so far as they produce good works in proportion to a supernatural last end, thus they have the character of virtue, truly and perfectly; and cannot be acquired by human acts, but are infused by God. Such like moral virtues cannot be without charity. For it has been stated above (A. 1; Q. 58, AA. 4, 5) that the other moral virtues cannot be without prudence; and that prudence cannot be without the moral virtues, because these latter make man well disposed to certain ends, which are the starting-point of the procedure of prudence. Now for prudence to proceed aright, it is much more necessary that man be well disposed towards his ultimate end, which is the effect of charity, than that he be well disposed in respect of other ends, which is the effect of moral virtue: just as in speculative matters right reason has greatest need of the first indemonstrable principle, that "contradictories cannot both be true at the same time." It is therefore evident that neither can infused prudence be without charity; nor, consequently, the other moral virtues, since they cannot be without prudence.
It is therefore clear from what has been said that only the infused virtues are perfect, and deserve to be called virtues simply: since they direct man well to the ultimate end. But the other virtues, those, namely, that are acquired, are virtues in a restricted sense, but not simply: for they direct man well in respect of the last end in some particular genus of action, but not in respect of the last end simply. Hence a gloss of Augustine [*Cf. Lib. Sentent. Prosperi cvi.] on the words, "All that is not of faith is sin" (Rom. 14:23), says: "He that fails to acknowledge the truth, has no true virtue, even if his conduct be good."
Reply Obj. 1: Virtue, in the words quoted, denotes imperfect virtue. Else if we take moral virtue in its perfect state, "it makes its possessor good," and consequently cannot be in the wicked.
Reply Obj. 2: This argument holds good of virtue in the sense of acquired virtue.
Reply Obj. 3: Though charity surpasses science and prudence, yet prudence depends on charity, as stated: and consequently so do all the infused moral virtues.
^Q. 65 Art. 3: Whether charity can be without moral virtue?
Obj. 1: It would seem possible to have charity without the moral virtues. For when one thing suffices for a certain purpose, it is superfluous to employ others. Now charity alone suffices for the fulfilment of all the works of virtue, as is clear from 1 Cor. 13:4, seqq.: "Charity is patient, is kind," etc. Therefore it seems that if one has charity, other virtues are superfluous.
Obj. 2: Further, he that has a habit of virtue easily performs the works of that virtue, and those works are pleasing to him for their own sake: hence "pleasure taken in a work is a sign of habit" (Ethic. ii, 3). Now many have charity, being free from mortal sin, and yet they find it difficult to do works of virtue; nor are these works pleasing to them for their own sake, but only for the sake of charity. Therefore many have charity without the other virtues.
Obj. 3: Further, charity is to be found in every saint: and yet there are some saints who are without certain virtues. For Bede says (on Luke 17:10) that the saints are more humbled on account of their not having certain virtues, than rejoiced at the virtues they have. Therefore, if a man has charity, it does not follow of necessity that he has all the moral virtues.
On the contrary, The whole Law is fulfilled through charity, for it is written (Rom. 13:8): "He that loveth his neighbor, hath fulfilled the Law." Now it is not possible to fulfil the whole Law, without having all the moral virtues: since the law contains precepts about all acts of virtue, as stated in Ethic. v, 1, 2. Therefore he that has charity, has all the moral virtues. Moreover, Augustine says in a letter (Epis. clxvii) [*Cf. Serm. xxxix and xlvi de Temp.] that charity contains all the cardinal virtues.
I answer that, All the moral virtues are infused together with charity. The reason for this is that God operates no less perfectly in works of grace than in works of nature. Now, in the works of nature, we find that whenever a thing contains a principle of certain works, it has also whatever is necessary for their execution: thus animals are provided with organs whereby to perform the actions that their souls empower them to do. Now it is evident that charity, inasmuch as it directs man to his last end, is the principle of all the good works that are referable to his last end. Wherefore all the moral virtues must needs be infused together with charity, since it is through them that man performs each different kind of good work.
It is therefore clear that the infused moral virtues are connected, not only through prudence, but also on account of charity: and, again, that whoever loses charity through mortal sin, forfeits all the infused moral virtues.
Reply Obj. 1: In order that the act of a lower power be perfect, not only must there be perfection in the higher, but also in the lower power: for if the principal agent were well disposed, perfect action would not follow, if the instrument also were not well disposed. Consequently, in order that man work well in things referred to the end, he needs not only a virtue disposing him well to the end, but also those virtues which dispose him well to whatever is referred to the end: for the virtue which regards the end is the chief and moving principle in respect of those things that are referred to the end. Therefore it is necessary to have the moral virtues together with charity.
Reply Obj. 2: It happens sometimes that a man who has a habit, finds it difficult to act in accordance with the habit, and consequently feels no pleasure and complacency in the act, on account of some impediment supervening from without: thus a man who has a habit of science, finds it difficult to understand, through being sleepy or unwell. In like manner sometimes the habits of moral virtue experience difficulty in their works, by reason of certain ordinary dispositions remaining from previous acts. This difficulty does not occur in respect of acquired moral virtue: because the repeated acts by which they are acquired, remove also the contrary dispositions.
Reply Obj. 3: Certain saints are said not to have certain virtues, in so far as they experience difficulty in the acts of those virtues, for the reason stated; although they have the habits of all the virtues.
^Q. 65 Art. 4: Whether faith and hope can be without charity?
Obj. 1: It would seem that faith and hope are never without charity. Because, since they are theological virtues, they seem to be more excellent than even the infused moral virtues. But the infused moral virtues cannot be without charity. Neither therefore can faith and hope be without charity.
Obj. 2: Further, "no man believes unwillingly" as Augustine says (Tract. xxvi in Joan.). But charity is in the will as a perfection thereof, as stated above (Q. 62, A. 3). Therefore faith cannot be without charity.
Obj. 3: Further, Augustine says (Enchiridion viii) that "there can be no hope without love." But love is charity: for it is of this love that he speaks. Therefore hope cannot be without charity.
On the contrary, A gloss on Matt. 1:2 says that "faith begets hope, and hope, charity." Now the begetter precedes the begotten, and can be without it. Therefore faith can be without hope; and hope, without charity.
I answer that, Faith and hope, like the moral virtues, can be considered in two ways; first in an inchoate state; secondly, as complete virtues. For since virtue is directed to the doing of good works, perfect virtue is that which gives the faculty of doing a perfectly good work, and this consists in not only doing what is good, but also in doing it well. Else, if what is done is good, but not well done, it will not be perfectly good; wherefore neither will the habit that is the principle of such an act, have the perfect character of virtue. For instance, if a man do what is just, what he does is good: but it will not be the work of a perfect virtue unless he do it well, i.e. by choosing rightly, which is the result of prudence; for which reason justice cannot be a perfect virtue without prudence.
Accordingly faith and hope can exist indeed in a fashion without charity: but they have not the perfect character of virtue without charity. For, since the act of faith is to believe in God; and since to believe is to assent to someone of one's own free will: to will not as one ought, will not be a perfect act of faith. To will as one ought is the outcome of charity which perfects the will: since every right movement of the will proceeds from a right love, as Augustine says (De Civ. Dei xiv, 9). Hence faith may be without charity, but not as a perfect virtue: just as temperance and fortitude can be without prudence. The same applies to hope. Because the act of hope consists in looking to God for future bliss. This act is perfect, if it is based on the merits which we have; and this cannot be without charity. But to expect future bliss through merits which one has not yet, but which one proposes to acquire at some future time, will be an imperfect act; and this is possible without charity. Consequently, faith and hope can be without charity; yet, without charity, they are not virtues properly so-called; because the nature of virtue requires that by it, we should not only do what is good, but also that we should do it well (Ethic. ii, 6).
Reply Obj. 1: Moral virtue depends on prudence: and not even infused prudence has the character of prudence without charity; for this involves the absence of due order to the first principle, viz. the ultimate end. On the other hand faith and hope, as such, do not depend either on prudence or charity; so that they can be without charity, although they are not virtues without charity, as stated.
Reply Obj. 2: This argument is true of faith considered as a perfect virtue.
Reply Obj. 3: Augustine is speaking here of that hope whereby we look to gain future bliss through merits which we have already; and this is not without charity.
^Q. 65 Art. 5: Whether charity can be without faith and hope?
It would seem that charity can be without faith and hope.
Obj. 1: For charity is the love of God. But it is possible for us to love God naturally, without already having faith, or hope in future bliss. Therefore charity can be without faith and hope.
Obj. 2: Further, charity is the root of all the virtues, according to Eph. 3:17: "Rooted and founded in charity." Now the root is sometimes without branches. Therefore charity can sometimes be without faith and hope, and the other virtues.
Obj. 3: Further, there was perfect charity in Christ. And yet He had neither faith nor hope: because He was a perfect comprehensor, as we shall explain further on (III, Q. 7, AA. 3, 4). Therefore charity can be without faith and hope.
On the contrary, The Apostle says (Heb. 11:6): "Without faith it is impossible to please God"; and this evidently belongs most to charity, according to Prov. 8:17: "I love them that love me." Again, it is by hope that we are brought to charity, as stated above (Q. 62, A. 4). Therefore it is not possible to have charity without faith and hope.
I answer that, Charity signifies not only the love of God, but also a certain friendship with Him; which implies, besides love, a certain mutual return of love, together with mutual communion, as stated in Ethic. viii, 2. That this belongs to charity is evident from 1 John 4:16: "He that abideth in charity, abideth in God, and God in him," and from 1 Cor. 1:9, where it is written: "God is faithful, by Whom you are called unto the fellowship of His Son." Now this fellowship of man with God, which consists in a certain familiar colloquy with Him, is begun here, in this life, by grace, but will be perfected in the future life, by glory; each of which things we hold by faith and hope. Wherefore just as friendship with a person would be impossible, if one disbelieved in, or despaired of, the possibility of their fellowship or familiar colloquy; so too, friendship with God, which is charity, is impossible without faith, so as to believe in this fellowship and colloquy with God, and to hope to attain to this fellowship. Therefore charity is quite impossible without faith and hope.
Reply Obj. 1: Charity is not any kind of love of God, but that love of God, by which He is loved as the object of bliss, to which object we are directed by faith and hope.
Reply Obj. 2: Charity is the root of faith and hope, in so far as it gives them the perfection of virtue. But faith and hope as such are the precursors of charity, as stated above (Q. 62, A. 4), and so charity is impossible without them.
Reply Obj. 3: In Christ there was neither faith nor hope, on account of their implying an imperfection. But instead of faith, He had manifest vision, and instead of hope, full comprehension [*See above, Q. 4, A. 3]: so that in Him was perfect charity.
^Q. 65 QUESTION 66: OF EQUALITY AMONG THE VIRTUES ^TOC ^Of Certain Properties of Virtues We must now consider equality among the virtues: under which head there are six points of inquiry: (1) Whether one virtue can be greater or less than another?
(2) Whether all the virtues existing together in one subject are equal?
(3) Of moral virtue in comparison with intellectual virtue; (4) Of the moral virtues as compared with one another; (5) Of the intellectual virtues in comparison with one another; (6) Of the theological virtues in comparison with one another.
Art. 1: Whether one virtue can be greater or less than another?
It would seem that one virtue cannot be greater or less than another.
Obj. 1: For it is written (Apoc. 21:16) that the sides of the city of Jerusalem are equal; and a gloss says that the sides denote the virtues. Therefore all virtues are equal; and consequently one cannot be greater than another.
Obj. 2: Further, a thing that, by its nature, consists in a maximum, cannot be more or less. Now the nature of virtue consists in a maximum, for virtue is "the limit of power," as the Philosopher states (De Coelo i, text. 116); and Augustine says (De Lib. Arb. ii, 19) that "virtues are very great boons, and no one can use them to evil purpose." Therefore it seems that one virtue cannot be greater or less than another.
Obj. 3: Further, the quantity of an effect is measured by the power of the agent. But perfect, viz. infused virtues, are from God Whose power is uniform and infinite. Therefore it seems that one virtue cannot be greater than another.
On the contrary, Wherever there can be increase and greater abundance, there can be inequality. Now virtues admit of greater abundance and increase: for it is written (Matt. 5:20): "Unless your justice abound more than that of the Scribes and Pharisees, you shall not enter into the kingdom of heaven": and (Prov. 15:5): "In abundant justice there is the greatest strength (virtus)." Therefore it seems that a virtue can be greater or less than another.
I answer that, When it is asked whether one virtue can be greater than another, the question can be taken in two senses. First, as applying to virtues of different species. In this sense it is clear that one virtue is greater than another; since a cause is always more excellent than its effect; and among effects, those nearest to the cause are the most excellent. Now it is clear from what has been said (Q. 18, A. 5; Q. 61, A. 2) that the cause and root of human good is the reason. Hence prudence which perfects the reason, surpasses in goodness the other moral virtues which perfect the appetitive power, in so far as it partakes of reason. And among these, one is better than another, according as it approaches nearer to the reason. Consequently justice, which is in the will, excels the remaining moral virtues; and fortitude, which is in the irascible part, stands before temperance, which is in the concupiscible, which has a smaller share of reason, as stated in Ethic. vii, 6.
The question can be taken in another way, as referring to virtues of the same species. In this way, according to what was said above (Q. 52, A. 1), when we were treating of the intensity of habits, virtue may be said to be greater or less in two ways: first, in itself; secondly with regard to the subject that partakes of it. If we consider it in itself, we shall call it great or little, according to the things to which it extends. Now whosoever has a virtue, e.g. temperance, has it in respect of whatever temperance extends to. But this does not apply to science and art: for every grammarian does not know everything relating to grammar. And in this sense the Stoics said rightly, as Simplicius states in his Commentary on the Predicaments, that virtue cannot be more or less, as science and art can; because the nature of virtue consists in a maximum.
If, however, we consider virtue on the part of the subject, it may then be greater or less, either in relation to different times, or in different men. Because one man is better disposed than another to attain to the mean of virtue which is defined by right reason; and this, on account of either greater habituation, or a better natural disposition, or a more discerning judgment of reason, or again a greater gift of grace, which is given to each one "according to the measure of the giving of Christ," as stated in Eph. 4:9. And here the Stoics erred, for they held that no man should be deemed virtuous, unless he were, in the highest degree, disposed to virtue. Because the nature of virtue does not require that man should reach the mean of right reason as though it were an indivisible point, as the Stoics thought; but it is enough that he should approach the mean, as stated in Ethic. ii, 6. Moreover, one same indivisible mark is reached more nearly and more readily by one than by another: as may be seen when several archers aim at a fixed target.
Reply Obj. 1: This equality is not one of absolute quantity, but of proportion: because all virtues grow in a man proportionately, as we shall see further on (A. 2).
Reply Obj. 2: This "limit" which belongs to virtue, can have the character of something more or less good, in the ways explained above: since, as stated, it is not an indivisible limit.
Reply Obj. 3: God does not work by necessity of nature, but according to the order of His wisdom, whereby He bestows on men various measures of virtue, according to Eph. 4:7: "To every one of you [Vulg.: 'us'] is given grace according to the measure of the giving of Christ."
^Q. 66 Art. 2: Whether all the virtues that are together in one man, are equal?
It would seem that the virtues in one same man are not all equally intense.
Obj. 1: For the Apostle says (1 Cor. 7:7): "Everyone hath his proper gift from God; one after this manner, and another after that." Now one gift would not be more proper than another to a man, if God infused all the virtues equally into each man. Therefore it seems that the virtues are not all equal in one and the same man.
Obj. 2: Further, if all the virtues were equally intense in one and the same man, it would follow that whoever surpasses another in one virtue, would surpass him in all the others. But this is clearly not the case: since various saints are specially praised for different virtues; e.g. Abraham for faith (Rom. 4), Moses for his meekness (Num. 7:3), Job for his patience (Tob. 2:12). This is why of each Confessor the Church sings: "There was not found his like in keeping the law of the most High," [*See Lesson in the Mass Statuit (Dominican Missal)], since each one was remarkable for some virtue or other. Therefore the virtues are not all equal in one and the same man.
Obj. 3: Further, the more intense a habit is, the greater one's pleasure and readiness in making use of it. Now experience shows that a man is more pleased and ready to make use of one virtue than of another. Therefore the virtues are not all equal in one and the same man.
On the contrary, Augustine says (De Trin. vi, 4) that "those who are equal in fortitude are equal in prudence and temperance," and so on. Now it would not be so, unless all the virtues in one man were equal. Therefore all virtues are equal in one man.
I answer that, As explained above (A. 1), the comparative greatness of virtues can be understood in two ways. First, as referring to their specific nature: and in this way there is no doubt that in a man one virtue is greater than another, for example, charity, than faith and hope. Secondly, it may be taken as referring to the degree of participation by the subject, according as a virtue becomes intense or remiss in its subject. In this sense all the virtues in one man are equal with an equality of proportion, in so far as their growth in man is equal: thus the fingers are unequal in size, but equal in proportion, since they grow in proportion to one another.
Now the nature of this equality is to be explained in the same way as the connection of virtues; for equality among virtues is their connection as to greatness. Now it has been stated above (Q. 65, A. 1) that a twofold connection of virtues may be assigned. The first is according to the opinion of those who understood these four virtues to be four general properties of virtues, each of which is found together with the other in any matter. In this way virtues cannot be said to be equal in any matter unless they have all these properties equal. Augustine alludes to this kind of equality (De Trin. vi, 4) when he says: "If you say these men are equal in fortitude, but that one is more prudent than the other; it follows that the fortitude of the latter is less prudent. Consequently they are not really equal in fortitude, since the former's fortitude is more prudent. You will find that this applies to the other virtues if you run over them all in the same way."
The other kind of connection among virtues followed the opinion of those who hold these virtues to have their own proper respective matters (Q. 65, AA. 1, 2). In this way the connection among moral virtues results from prudence, and, as to the infused virtues, from charity, and not from the inclination, which is on the part of the subject, as stated above (Q. 65, A. 1). Accordingly the nature of the equality among virtues can also be considered on the part of prudence, in regard to that which is formal in all the moral virtues: for in one and the same man, so long as his reason has the same degree of perfection, the mean will be proportionately defined according to right reason in each matter of virtue.
But in regard to that which is material in the moral virtues, viz. the inclination to the virtuous act, one may be readier to perform the act of one virtue, than the act of another virtue, and this either from nature, or from habituation, or again by the grace of God.
Reply Obj. 1: This saying of the Apostle may be taken to refer to the gifts of gratuitous grace, which are not common to all, nor are all of them equal in the one same subject. We might also say that it refers to the measure of sanctifying grace, by reason of which one man has all the virtues in greater abundance than another man, on account of his greater abundance of prudence, or also of charity, in which all the infused virtues are connected.
Reply Obj. 2: One saint is praised chiefly for one virtue, another saint for another virtue, on account of his more admirable readiness for the act of one virtue than for the act of another virtue.
This suffices for the Reply to the Third Objection.
^Q. 66 Art. 3: Whether the moral virtues are better than the intellectual virtues?
It would seem that the moral virtues are better than the intellectual.
Obj. 1: Because that which is more necessary, and more lasting, is better. Now the moral virtues are "more lasting even than the sciences" (Ethic. i) which are intellectual virtues: and, moreover, they are more necessary for human life. Therefore they are preferable to the intellectual virtues.
Obj. 2: Further, virtue is defined as "that which makes its possessor good." Now man is said to be good in respect of moral virtue, and art in respect of intellectual virtue, except perhaps in respect of prudence alone. Therefore moral is better than intellectual virtue.
Obj. 3: Further, the end is more excellent than the means. But according to Ethic. vi, 12, "moral virtue gives right intention of the end; whereas prudence gives right choice of the means." Therefore moral virtue is more excellent than prudence, which is the intellectual virtue that regards moral matters.
On the contrary, Moral virtue is in that part of the soul which is rational by participation; while intellectual virtue is in the essentially rational part, as stated in Ethic. i, 13. Now rational by essence is more excellent than rational by participation. Therefore intellectual virtue is better than moral virtue.
I answer that, A thing may be said to be greater or less in two ways: first, simply; secondly, relatively. For nothing hinders something from being better simply, e.g. "learning than riches," and yet not better relatively, i.e. "for one who is in want" [*Aristotle, Topic. iii.]. Now to consider a thing simply is to consider it in its proper specific nature. Accordingly, a virtue takes its species from its object, as explained above (Q. 54, A. 2; Q. 60, A. 1). Hence, speaking simply, that virtue is more excellent, which has the more excellent object. Now it is evident that the object of the reason is more excellent than the object of the appetite: since the reason apprehends things in the universal, while the appetite tends to things themselves, whose being is restricted to the particular. Consequently, speaking simply, the intellectual virtues, which perfect the reason, are more excellent than the moral virtues, which perfect the appetite.
But if we consider virtue in its relation to act, then moral virtue, which perfects the appetite, whose function it is to move the other powers to act, as stated above (Q. 9, A. 1), is more excellent. And since virtue is so called from its being a principle of action, for it is the perfection of a power, it follows again that the nature of virtue agrees more with moral than with intellectual virtue, though the intellectual virtues are more excellent habits, simply speaking.
Reply Obj. 1: The moral virtues are more lasting than the intellectual virtues, because they are practised in matters pertaining to the life of the community. Yet it is evident that the objects of the sciences, which are necessary and invariable, are more lasting than the objects of moral virtue, which are certain particular matters of action. That the moral virtues are more necessary for human life, proves that they are more excellent, not simply, but relatively. Indeed, the speculative intellectual virtues, from the very fact that they are not referred to something else, as a useful thing is referred to an end, are more excellent. The reason for this is that in them we have a kind of beginning of that happiness which consists in the knowledge of truth, as stated above (Q. 3, A. 6).
Reply Obj. 2: The reason why man is said to be good simply, in respect of moral virtue, but not in respect of intellectual virtue, is because the appetite moves the other powers to their acts, as stated above (Q. 56, A. 3). Wherefore this argument, too, proves merely that moral virtue is better relatively.
Reply Obj. 3: Prudence directs the moral virtues not only in the choice of the means, but also in appointing the end. Now the end of each moral virtue is to attain the mean in the matter proper to that virtue; which mean is appointed according to the right ruling of prudence, as stated in Ethic. ii, 6; vi, 13.
^Q. 66 Art. 4: Whether justice is the chief of the moral virtues?
It would seem that justice is not the chief of the moral virtues.
Obj. 1: For it is better to give of one's own than to pay what is due. Now the former belongs to liberality, the latter to justice. Therefore liberality is apparently a greater virtue than justice.
Obj. 2: Further, the chief quality of a thing is, seemingly, that in which it is most perfect. Now, according to Jam. 1:4, "Patience hath a perfect work." Therefore it would seem that patience is greater than justice.
Obj. 3: Further, "Magnanimity has a great influence on every virtue," as stated in Ethic. iv, 3. Therefore it magnifies even justice. Therefore it is greater than justice.
On the contrary, The Philosopher says (Ethic. v, 1) that "justice is the most excellent of the virtues."
I answer that, A virtue considered in its species may be greater or less, either simply or relatively. A virtue is said to be greater simply, whereby a greater rational good shines forth, as stated above (A. 1). In this way justice is the most excellent of all the moral virtues, as being most akin to reason. This is made evident by considering its subject and its object: its subject, because this is the will, and the will is the rational appetite, as stated above (Q. 8, A. 1; Q. 26, A. 1): its object or matter, because it is about operations, whereby man is set in order not only in himself, but also in regard to another. Hence "justice is the most excellent of virtues" (Ethic. v, 1). Among the other moral virtues, which are about the passions, the more excellent the matter in which the appetitive movement is subjected to reason, so much the more does the rational good shine forth in each. Now in things touching man, the chief of all is life, on which all other things depend. Consequently fortitude which subjects the appetitive movement to reason in matters of life and death, holds the first place among those moral virtues that are about the passions, but is subordinate to justice. Hence the Philosopher says (Rhet. 1) that "those virtues must needs be greatest which receive the most praise: since virtue is a power of doing good. Hence the brave man and the just man are honored more than others; because the former," i.e. fortitude, "is useful in war, and the latter," i.e.
justice, "both in war and in peace." After fortitude comes temperance, which subjects the appetite to reason in matters directly relating to life, in the one individual, or in the one species, viz. in matters of food and of sex. And so these three virtues, together with prudence, are called principal virtues, in excellence also.
