Ancient & Medieval Philosophy -- David L. Rouse
SOCRATES: This. 'In point of fact, Tisias, we have for some time before you came on the scene been saying that the multitude get their notion of probability as the result of a likeness to truth, and we explained just now that these likenesses can always be best discovered by one who knows the truth. Therefore if you have anything else to say about the art of speech, we should be glad to hear it, but if not we shall adhere to the point we made just now, namely that unless the aspirant to oratory can on the one hand list the various natures among his prospective audiences, and on the other divide things into their kinds and embrace each individual thing under a single form, he will never attain such success as is within the grasp of mankind.
