It might well be said that it was impossible to contradict you at any point of the argument, but yet that it was perfectly plain that people who study philosophy too long, and don’t treat it simply as part of their early education and then drop it, become, most of them, rather strange, not to say thoroughly vicious; while even the best of them are reduced by this study you praise so highly to complete uselessness as members of society. - Adeimantus to Socrates in The Republic
