But as for the knowledge of things—or if you do not so much approve of this word _cognitio_, or find it less intelligible, we will call it κατάληψις—that we think is naturally to be acquired for its own sake, because it contains something which has, as it were, embraced and seized upon truth. And this is perceptible even in infants; whom we see amused if they have succeeded in finding out anything themselves by reason, even though it may be of no service whatever to them. And moreover, we consider arts worth attending to on their own account, both because there is in them something worth acceptance, and also because they depend upon knowledge, and contain in themselves something which proceeds on system and method. But I think that we are more averse to assent on false grounds than to anything else which is contrary to nature. Now of the limbs, that is to say, of the parts of the body, some appear to have been given to us by nature because of the use which, they are of to us, as, for instance, the hands, legs, and feet, and also those internal organs of the body, of which I may leave it to the physicians to explain the exceeding usefulness; but others with no view to utility, but for ornament as it were, as the tail is given to the peacock, plumage of many colours to the dove, breasts and a beard to man. Perhaps you will say this is but a dry enumeration; for these things are, as it were, the first elements of nature, which cannot well have any richness of language employed upon them; nor indeed am I thinking of displaying any; but when one is speaking of more important matters, then the subject itself hurries on the language: and then one’s discourse is at the same time more impressive and more ornate. It is as you say, said I; but still everything which is said in a lucid manner about a good subject appears to me to be said well. And to wish to speak of subjects of that kind in a florid style is childish; but to be able to explain them with clearness and perspicuity, is a token of a learned and intelligent man.
