THEAETETUS: I should have to think a long while. STRANGER: In all the previously named processes either like has been separated from like or the better from the worse. THEAETETUS: I see now what you mean. STRANGER: There is no name for the first kind of separation; of the second, which throws away the worse and preserves the better, I do know a name. THEAETETUS: What is it? STRANGER: Every discernment or discrimination of that kind, as I have observed, is called a purification. THEAETETUS: Yes, that is the usual expression.

And as to your question concerning the name which was to comprehend all these arts of purification, whether of animate or inanimate bodies, the art of dialectic is in 747
