 should be any difference to enable you to distinguish one from the other?—or, shall you have to seek out some ring engraver, since you have already found us a Delian poulterer who could recognise his eggs?

Well? Does not this argument seem to tell against you, if, without great skill, such as very few persons of our class attain to, we can neither see nor hear?

Can you also, Lucullus, affirm that there is any power united with wisdom and prudence which has made, or, to use your own expression, manufactured man? What sort of a manufacture is that?

Let it be said even that they appear likely; only let them not be affirmed positively. But we will discuss natural philosophy hereafter, and, indeed, we will do so that you, who said a little while ago that I should speak of it, may appear not to have spoken falsely.

However, to come to what is clearer, I shall now bring forward general facts on which whole volumes have been filled, not only by those of our own School, but also by Chrysippus. But the Stoics complain of him, that, while he studiously collected every argument which could be brought forward against the senses and clearness, and against all custom, and against reason, when he came to reply to himself, he was inferior to what he had been at first; and therefore that, in fact, he put arms into the hands of Carneades.
