 Epicurus himself says, that one ought not even to argue about pleasure, because the decision respecting it depends on the sensations, so that it is sufficient for us to be warned respecting it, and quite unnecessary for us to be instructed. And on this account, that previous discussion of ours was a simple one on both sides; for there was nothing involved or intricate in the discourse of Torquatus, and my own language, as it seems to me, was very clear. But you are not ignorant what a subtle, or I might rather say, thorny kind of arguing it is which is employed by the Stoics. And if it is so among the Greeks, much more so is it among us, who are forced even to invent words, and to give new names to new things. And this is what no one who is even moderately learned will wonder at, when he considers that in every art which is not in common and ordinary use, there is a great variety of new names, as appellations are forced to be given to everything about which each art is conversant. Therefore, both dialecticians and natural philosophers use those words which are not common in the ordinary conversation of the Greeks; and geometricians, musicians, and grammarians, all speak after a peculiar fashion of their own. And even the rhetoricians, whose art is a forensic one, and wholly directed to the people, still in giving their lessons use words which are, as it were, their peculiar private property.

II. And, without dwelling on the case of these liberal and gentlemanly professions, even artisans would not be capable of exercising their trades properly if they did not use technical words, which are not understood by us, though in common use among them. Agriculture, also, which is as distant as can be from all polite refinement, still marks those matters with which it is conversant by new names. And much more is this course allowable in a philosopher; for philosophy is the art of life, and a man who is discussing that cannot borrow his language from the forum,—although there is no school of philosophers which has made so many innovations as the Stoics. Zeno too, their chief, was not so much a discoverer of new things as of new words. But if, even in that language which most people consider richer than our own, Greece has permitted the most learned men to use words not in ordinary use about subjects which are equally unusual, how much more ought the same licence to be granted to us,
