485a-d (tr. W.R.M. Lamb):
It is a fine thing to partake of philosophy just for the sake of education, and it is no disgrace for a lad to follow it: but when a man already advancing in years continues in its pursuit, the affair, Socrates, becomes ridiculous; and for my part I have much the same feeling towards students of philosophy as towards those who lisp or play tricks. For when I see a little child, to whom it is still natural to talk in that way, lisping or playing some trick, I enjoy it, and it strikes me as pretty and ingenuous and suitable to the infant's age; whereas if I hear a small child talk distinctly, I find it a disagreeable thing, and it offends my ears and seems to me more befitting a slave. But when one hears a grown man lisp, or sees him play tricks, it strikes one as something ridiculous and unmanly, that deserves a whipping. Just the same, then, is my feeling towards the followers of philosophy. For when I see philosophy in a young lad I approve of it; I consider it suitable, and I regard him as a person of liberal mind: whereas one who does not follow it I account illiberal and never likely to expect of himself any fine or generous action. But when I see an elderly man still going on with philosophy and not getting rid of it, that is the gentleman, Socrates, whom I think in need of a whipping.
