THEAETETUS: How? and of what sort do you mean? SOCRATES: 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? THEAETETUS: Very true. SOCRATES: 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? THEAETETUS: 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. SOCRATES: 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. (In allusion to the well-known line of Euripides, Hippol.: e gloss omomoch e de thren anomotos.) THEAETETUS: Very true. SOCRATES: 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. THEAETETUS: Yes, that would be my desire. SOCRATES: And mine too. But since this is our feeling, and there is plenty of time, why should we not calmly and patiently review our own thoughts, and thoroughly examine and see what these appearances in us really are? If I am not mistaken, they will be described by us as follows:—first, that nothing can become greater or less, either in number or magnitude, while remaining equal to itself—you would agree? THEAETETUS: Yes. SOCRATES: Secondly, that without addition or subtraction there is no increase or diminution of anything, but only equality. THEAETETUS: Quite true. SOCRATES: Thirdly, that what was not before cannot be afterwards, without becoming and having become. 604
