Cicero, the cardinal virtues?

again, from the De Officiis

{15} V.

You see here, Marcus, my son, the very form and as it were the face of Moral Goodness; "and if," as Plato says, "it could be seen with the physical eye, it would awaken a marvellous love of wisdom." But all that is morally right rises from some one of four sources: it is concerned either (1) with the full perception and intelligent development of the true; or (2) with the conservation of organized society, with rendering to every man his due, and with the faithful discharge of obligations assumed; or (3) with the greatness and strength of a noble and invincible spirit; or (4) with the orderliness and moderation of everything that is said and done, wherein consist temperance and self-control. Although these four are connected and interwoven, still it is in each one considered singly that certain definite kinds of moral duties have their origin: in that category, for instance, which was designated first in our division and in which we place wisdom and prudence, belong the search after truth and its discovery; and this is the peculiar {16} province of that virtue. For the more clearly anyone observes the most essential truth in any given case and the more quickly and accurately he can see and explain the reasons for it, the more understanding and wise he is generally esteemed, and justly so. So, then, it is truth that is, as it were, the stuff with which this virtue has to deal and on which it employs itself.

{17} Before the three remaining virtues, on the other hand, is set the task of providing and maintaining those things on which the practical business of life depends so that the relations of man to man in human society may be conserved, and that largeness and nobility of soul may be revealed not only in increasing one's resources and acquiring advantages for one's self and one's family but far more in rising superior to these very things. But orderly behaviour and consistency of demeanor and self-control and the like have their sphere in that department of things in which a certain amount of physical exertion, and not mental activity merely, is required. For if we bring a certain amount of propriety and order into the transactions of daily life, we shall be conserving moral rectitude and moral dignity.

{18} VI.

Now, of the four divisions which we have made of the essential idea of moral goodness, the first, consisting in the knowledge of truth, touches human nature most closely. For we are all attracted and drawn to a zeal for learning and knowing; and we think it glorious to excel therein, while we count it base and immoral to fall into error, to wander from the truth, to be ignorant, to be led astray. In this pursuit, which is both natural and morally right, two errors are to be avoided: first, we must not treat the unknown as known and too readily accept it; and he who wishes to avoid this error (as all should do) will devote both time and attention

{19} to the weighing of evidence. The other error is that some people devote too much industry and too deep study to matters that are obscure and difficult and useless as well. If these errors are successfully avoided, all the labour and pains expended upon problems that are morally right and worth the solving will be fully rewarded. Such a worker in the field of astronomy, for example, was Gaius Sulpicius, of whom we have heard; in mathematics, Sextus Pompey, whom I have known personally; in dialectics, many; in civil law, still more. All these professions are occupied with the search after truth; but to be drawn by study away from active life is contrary to moral duty. For the whole glory of virtue is in activity; activity, however, may often be interrupted, and many opportunities for returning to study are opened. Besides, the working of the mind, which is never at rest, can keep us busy in the pursuit of knowledge even without conscious effort on our part. Moreover, all our thought and mental activity will be devoted either to planning for things that are morally right and that conduce to a good and happy life, or to the pursuits of science and learning. With this we close the discussion of the first source of duty.

{20} VII.

Of the three remaining divisions, the most extensive in its application is the principle by which society and what we may call its "common bonds" are maintained. Of this again there are two divisions — justice, in which is the crowning glory of the virtues and on the basis of which men are called "good men"; and, close akin to justice, charity, which may also be called kindness or generosity. The first office of justice is to keep one man from doing harm to another, unless provoked by wrong; and the next is to lead men to use common possessions for the common interests, private property for their own.

{21} There is, however, no such thing as private ownership established by nature, but property becomes private either through long occupancy (as in the case of those who long ago settled in unoccupied territory) or through conquest (is in the case of those who took it in war) or by due process of law, bargain, or purchase, or by allotment. On this principle the lands of Arpinum are said to belong to the Arpinates, the Tusculan lands to the Tusculans; and similar is the assignment of private property. Therefore, inasmuch as in each case some of those things which by nature had been common property became the property of individuals, each one should retain possession of that which has fallen to his lot; and if anyone appropriates to himself anything beyond that, he will be violating the laws of human society.

{22} But since, as Plato has admirably expressed it, we are not born for ourselves alone, but our country claims a share of our being, and our friends a share; and since, as the Stoics hold, everything that the earth produces is created for man's use; and as men, too, are born for the sake of men, that they may be able mutually to help one another; in this direction we ought to follow Nature as our guide, to contribute to the general good by an interchange of acts of kindness, by giving and receiving, and thus by our skill, our industry, and our talents to cement human society more closely together, man to man.

{23} The foundation of justice, moreover, is good_faith; — that is, truth and fidelity to promises and agreements. And therefore we may follow the Stoics, who diligently investigate the etymology of words; and we may accept their statement that "good faith" is so called because what is promised is "made good," although some may find this derivation/a rather farfetched. There are, on the other hand, two kinds of injustice — the one, on the part of those who inflict wrong, the other on the part of those who, when they can, do not shield from wrong those upon whom it is being inflicted. For he who, under the influence of anger or some other passion, wrongfully assaults another seems, as it were, to be laying violent hands upon a comrade; but he who does not prevent or oppose wrong, if he can, is just as guilty of wrong as if he deserted his parents or his friends or his country.

{24} Then, too, those very wrongs which people try to inflict on purpose to injure are often the result of fear: that is, he who premeditates injuring another is afraid that, if he does not do so, he may himself be made to suffer some hurt. But, for the most part, people are led to wrong-doing in order to secure some personal end; in this vice, avarice is generally the controlling motive.
