Soc. Or that anything appears the same to you as to another man? Are you so profoundly convinced of this? Rather would it not be true that it never appears exactly the same to you, because you are never exactly the same?
Theaet. The latter.
Soc. And if that with which I compare myself in size, or which I apprehend by touch, were great or white or hot, it could not become different by mere contact with another unless it actually changed; nor again, if the comparing or apprehending subject were great or white or hot, could this, when unchanged from within become changed by any approximation or affection of any other thing. The fact is that in our ordinary way of speaking we allow ourselves to be driven into most ridiculous and wonderful contradictions, as Protagoras and all who take his line of argument would remark.
Theaet. How? and of what sort do you mean?
Soc. A little instance will sufficiently explain my meaning: Here are six dice, which are more by a half when compared with four, and fewer by a half than twelve - they are more and also fewer. How can you or any one maintain the contrary?
Theaet. Very true.
Soc. Well, then, suppose that Protagoras or some one asks whether anything can become greater or more if not by increasing, how would you answer him, Theaetetus?
Theaet. I should say "No," Socrates, if I were to speak my mind in reference to this last question, and if I were not afraid of contradicting my former answer.
Soc. Capital excellent! spoken like an oracle, my boy! And if you reply "Yes," there will be a case for Euripides; for our tongue will be unconvinced, but not our mind.
Theaet. Very true.
Soc. The thoroughbred Sophists, who know all that can be known about the mind, and argue only out of the superfluity of their wits, would have had a regular sparring - match over this, and would - have knocked their arguments together finely. But you and I, who have no professional aims, only desire to see what is the mutual relation of these principles - whether they are consistent with each or not.
Theaet. Yes, that would be my desire.
