SOCRATES: And will you on this account shun all these pursuits yourself and refuse to allow them to your son?

CRITO: That would not be reasonable, Socrates.

SOCRATES: Do you then be reasonable, Crito, and do not mind whether the teachers of philosophy are good or bad, but think only of philosophy herself. Try and examine her well and truly, and if she be evil seek to turn away all men from her, and not your sons only; but if she be what I believe that she is, then follow her and serve her, you and your house, as the saying is, and be of good cheer.
