Plato (427?347 B.C.)
That makes me think, my friend, as I have often done before, how natural it is that those who have spent a long time in the study of philosophy appear ridiculous when they enter the courts of law as speakers . Those who have knocked about in courts and the like from their youth up seem to me, when compared with those who have been brought up in philosophy and similar pursuits, to be as slaves in breeding compared with freemen.
PLATO, Theaetetus, trans. H. N. Fowler, p. 115 (1921).
