Again, every one of you could name many of your schoolfellows who when they were boys seemed to be the dullest among their companions, but who, growing older, outstripped them farther in intelligence and in speech than they had lagged behind them when they were boys. From this fact you can best judge what training can do; for it is evident that when they were young they all possessed such mental powers as they were born with, but as they grew to be men, these outstripped the others and changed places with them in intelligence, because their companions lived dissolutely and softly, while they gave heed to their own opportunities and to their own welfare.
