like demonstration, but are not demonstration? Do you know what is true or what is false? What is consequent on a thing, what is repugnant to a thing, or not consistent, or inconsistent?[1] But must I excite you to philosophy, and how? Shall I show to you the repugnance in the opinions of most men, through which they differ about things good and evil, and about things which are profitable and unprofitable, when you know not this very thing, what repugnance (contradiction) is? Show me then what I shall accomplish by discoursing with you: excite my inclination to do this. As the grass which is suitable, when it is presented to a sheep, moves its inclination to eat, but if you present to it a stone or bread, it will not be moved to eat; so there are in us certain natural inclinations also to speak, when the hearer shall appear to be somebody, when he himself shall excite us: but when he shall sit by us like a stone or like grass, how can he excite a man's desire (to speak)? Does the vine say to the husbandman, Take care of me? No, but the vine by showing in itself that it will be profitable to the husbandman, if he does take care of it, invites him to exercise care. When children are attractive and lively, whom do they not invite to play with them, and crawl with them, and lisp with them? But who is eager to play with an ass or to bray with it? for though it is small, it is still a little ass.
Why then do you say nothing to me? I can only say this to you, that he who knows not who he is, and for what purpose he exists, and what is this world, and with whom he is associated, and what things are the good and the bad, and the beautiful and the ugly, and who neither understands discourse nor demonstration, nor what is true nor what is false, and who is not able to distinguish them, will neither desire according to nature nor turn away nor move towards, nor intend (to act), nor assent, nor dissent nor suspend his judgment: to say all in a few words, he will go about dumb and blind, thinking that he is somebody, but being nobody. Is this so now for the first time? Is it not the fact that ever since the human race existed, all errors and misfortunes have arisen through this igno-
