IV. But lest I should do the very thing which I am blaming, I will pass over all these matters, which are so far from the subject that they are not even connected with it. Only do you protect me, if any one attacks me for putting down Chrysippus, who, by Hercules, was a great man, but yet a Greek, whose intellect, too sharply pointed, is often bent and turned back upon itself; even when it seems to be in earnest it only pricks, but does not pierce. Here, however, what occasion is there for subtlety? We are to speak of benefits, and to define a matter which is the chief bond of human society; we are to lay down a rule of life, such that neither careless openhandedness may commend itself to us under the guise of goodness of heart, and yet that our circumspection, while it moderates, may not quench our generosity, a quality in which we ought neither to exceed nor to fall short. Men must be taught to be willing to give, willing to receive, willing to return; and to place before themselves the high aim, not merely of equalling, but even of surpassing those to whom they are indebted, both in good offices and in good feeling; because the man whose duty it is to repay, can never do so unless he out-does his benefactor; [Footnote: That is, he never comes up to his benefactor unless he leaves him behind: he can only make a dead heat of it by getting a start.] the one class must be taught to look for no return, the other to feel deeper gratitude. In this noblest of contests to outdo benefits by benefits, Chrysippus encourages us by bidding us beware lest, as the Graces are the daughters of Jupiter, to act ungratefully may not be a sin against them, and may not wrong those beauteous maidens. Do thou teach me how I may bestow more good things, and be more grateful to those who have earned my gratitude, and how the minds of both parties may vie with one another, the giver in forgetting, the receiver in remembering his debt. As for those other follies, let them be left to the poets, whose purpose is merely to charm the ear and to weave a pleasing story; but let those who wish to purify men's minds, to retain honour in their dealings, and to imprint on their minds gratitude for kindnesses, let them speak in sober earnest and act with all their strength; unless you imagine, perchance, that by such flippant and mythical talk, and such old wives' reasoning, it is possible for us to prevent that most ruinous consummation, the repudiation of benefits.
