Str. We must therefore endeavor by practice to acquire the power of giving and understanding a rational definition of each one of them; for immaterial things, which are the noblest and greatest, can be exhibited by reason only, and it is for their sake that all we are saying is said. But it is always easier to practise in small matters than in greater ones.
Y. Soc. Excellent.
Str. Let us, then, remember the reason for all that we have said about these matters.
Y. Soc. What is the reason?
Str. The reason is chiefly just that irritating impatience which we exhibited in relation to the long talk about weaving and the revolution of the universe and the sophist’s long talk about the existence of not-being. Footnote 1See Plat. theaet. 283, Plat. Theaet. 277, Plat. Soph. 261 We felt that they were too long, and we reproached ourselves for all of them, fearing that our talk was not only long, but irrelevant. Consider, therefore, that the reason for what has just been said is my wish to avoid any such impatience in the future.
Y. Soc. Very well. Please go on with what you have to say.
Str. What I have to say, then, is that you and I, remembering what has just been said, must praise or blame the brevity or length of our several discussions, not by comparing their various lengths with one another, but with reference to that part of the science of measurement which we said before must be borne in mind; I mean the standard of fitness.
Y. Soc. Quite right.
