Str. And it is in this way, I fancy, that we have provided a fine feast for youngsters and for old men whose learning has come to them late in life; for example, it is easy enough for anyone to grasp the notion that the many cannot possibly be one, nor the one many, and so, apparently, they take pleasure in saying that we must not call a man good, but must call the good good, and a man man. I fancy, Theaetetus, you often run across people who take such matters seriously; sometimes they are elderly men whose poverty of intellect makes them admire such quibbles, and who think this is a perfect mine of wisdom they have discovered. Those are here satirized who deny the possibillty of all except identical predication. Such were Antisthenes, Euthydemus, and Dionysodorus. The two last are probably those referred to as old men whose learning came late in life.
251
Theaet. Certainly.
251
Str. Then, to include in our discussion all those who have ever engaged in any talk whatsoever about being, let us address our present arguments to these men as well as to all those with whom we were conversing before, and let us employ the form of questions.
251
Theaet. What are the arguments?
251
Str. Shall we attribute neither being to rest and motion, nor any attribute to anything, but shall we in our discussions assume that they do not mingle and cannot participate in one another? Or shall we gather all things together, believing that they are capable of combining with one another? Or are some capable of it and others not? Which of these alternatives, Theaetetus, should we say is their choice?
251
Theaet. I cannot answer these questions for them.
251
Str. Then why did you not answer each separately and see what the result was in each case?
251
Theaet. A good suggestion.
251
Str. And let us, if you please, assume that they say first that nothing has any power to combine with anything else. Then motion and rest will have no share in being, will they?
252
Theaet. No.
