Whether there is only one moral virtue about operations?
Objection 1: It would seem that there is but one moral virtue about operations. Because the rectitude of all external operations seems to belong to justice. Now justice is but one virtue. Therefore there is but one virtue about operations.
Objection 2: Further, those operations seem to differ most, which are directed on the one side to the good of the individual, and on the other to the good of the many. But this diversity does not cause diversity among the moral virtues: for the Philosopher says (Ethic. v, 1) that legal justice, which directs human acts to the common good, does not differ, save logically, from the virtue which directs a man's actions to one man only. Therefore diversity of operations does not cause a diversity of moral virtues.
Objection 3: Further, if there are various moral virtues about various operations, diversity of moral virtues would needs follow diversity of operations. But this is clearly untrue: for it is the function of justice to establish rectitude in various kinds of commutations, and again in distributions, as is set down in Ethic. v, 2. Therefore there are not different virtues about different operations.
On the contrary, Religion is a moral virtue distinct from piety, both of which are about operations.
I answer that, All the moral virtues that are about operations agree in one general notion of justice, which is in respect of something due to another: but they differ in respect of various special notions. The reason for this is that in external operations, the order of reason is established, as we have stated (A 2), not according as how man is affected towards such operations, but according to the becomingness of the thing itself; from which becomingness we derive the notion of something due which is the formal aspect of justice: for, seemingly, it pertains to justice that a man give another his due. Wherefore all such virtues as are about operations, bear, in some way, the character of justice. But the thing due is not of the same kind in all these virtues: for something is due to an equal in one way, to a superior, in another way, to an inferior, in yet another; and the nature of a debt differs according as it arises from a contract, a promise, or a favor already conferred. And corresponding to these various kinds of debt there are various virtues: e.g. "Religion" whereby we pay our debt to God; "Piety," whereby we pay our debt to our parents or to our country; "Gratitude," whereby we pay our debt to our benefactors, and so forth.
Reply to Objection 1: Justice properly so called is one special virtue, whose object is the perfect due, which can be paid in the equivalent. But the name of justice is extended also to all cases in which something due is rendered: in this sense it is not as a special virtue.
Reply to Objection 2: That justice which seeks the common good is another virtue from that which is directed to the private good of an individual: wherefore common right differs from private right; and Tully (De Inv. ii) reckons as a special virtue, piety which directs man to the good of his country. But that justice which directs man to the common good is a general virtue through its act of command: since it directs all the acts of the virtues to its own end, viz. the common good. And the virtues, in so far as they are commanded by that justice, receive the name of justice: so that virtue does not differ, save logically, from legal justice; just as there is only a logical difference between a virtue that is active of itself, and a virtue that is active through the command of another virtue.
Reply to Objection 3: There is the same kind of due in all the operations belonging to special justice. Consequently, there is the same virtue of justice, especially in regard to commutations. For it may be that distributive justice is of another species from commutative justice; but about this we shall inquire later on (SS, Q 61, A 1).
I–II · Q. 60, Art. 4: Whether there are different moral virtues about different passions?
Whether there are different moral virtues about different passions?
Objection 1: It would seem that there are not different moral virtues about different passions. For there is but one habit about things that concur in their source and end: as is evident especially in the case of sciences. But the passions all concur in one source, viz. love; and they all terminate in the same end, viz. joy or sorrow, as we stated above (Q 25, AA 1,2,4; Q 27, A 4). Therefore there is but one moral virtue about all the passions.
Objection 2: Further, if there were different moral virtues about different passions, it would follow that there are as many moral virtues as passions. But this clearly is not the case: since there is one moral virtue about contrary passions; namely, fortitude, about fear and daring; temperance, about pleasure and sorrow. Therefore there is no need for different moral virtues about different passions.
Objection 3: Further, love, desire, and pleasure are passions of different species, as stated above (Q 23, A 4). Now there is but one virtue about all these three, viz. temperance. Therefore there are not different moral virtues about different passions.
On the contrary, Fortitude is about fear and daring; temperance about desire; meekness about anger; as stated in Ethic. iii, 6,10; iv, 5.
I answer that, It cannot be said that there is only one moral virtue about all the passions: since some passions are not in the same power as other passions; for some belong to the irascible, others to the concupiscible faculty, as stated above (Q 23, A 1).
On the other hand, neither does every diversity of passions necessarily suffice for a diversity of moral virtues. First, because some passions are in contrary opposition to one another, such as joy and sorrow, fear and daring, and so on. About such passions as are thus in opposition to one another there must needs be one same virtue. Because, since moral virtue consists in a kind of mean, the mean in contrary passions stands in the same ratio to both, even as in the natural order there is but one mean between contraries, e.g. between black and white. Secondly, because there are different passions contradicting reason in the same manner, e.g. by impelling to that which is contrary to reason, or by withdrawing from that which is in accord with reason. Wherefore the different passions of the concupiscible faculty do not require different moral virtues, because their movements follow one another in a certain order, as being directed to the one same thing, viz. the attainment of some good or the avoidance of some evil: thus from love proceeds desire, and from desire we arrive at pleasure; and it is the same with the opposite passions, for hatred leads to avoidance or dislike, and this leads to sorrow. On the other hand, the irascible passions are not all of one order, but are directed to different things: for daring and fear are about some great danger; hope and despair are about some difficult good; while anger seeks to overcome something contrary which has wrought harm. Consequently there are different virtues about such like passions: e.g. temperance, about the concupiscible passions; fortitude, about fear and daring; magnanimity, about hope and despair; meekness, about anger.
Reply to Objection 1: All the passions concur in one common principle and end; but not in one proper principle or end: and so this does not suffice for the unity of moral virtue.
Reply to Objection 2: Just as in the natural order the same principle causes movement from one extreme and movement towards the other; and as in the intellectual order contraries have one common ratio; so too between contrary passions there is but one moral virtue, which, like a second nature, consents to reason's dictates.
Reply to Objection 3: Those three passions are directed to the same object in a certain order, as stated above: and so they belong to the same virtue.
