STRANGER: And in the case of the body are there not two arts which have to do with the two bodily states?
THEAETETUS: What are they?
STRANGER: There is gymnastic, which has to do with deformity, and medicine, which has to do with disease.
THEAETETUS: True.
STRANGER: And where there is insolence and injustice and cowardice, is not chastisement the art which is most required?
THEAETETUS: That certainly appears to be the opinion of mankind.
STRANGER: Again, of the various kinds of ignorance, may not instruction be rightly said to be the remedy?
THEAETETUS: True.
STRANGER: And of the art of instruction, shall we say that there is one or many kinds? At any rate there are two principal ones. Think.
THEAETETUS: I will.
