Seneca

“ And when you have progressed so far that you have also respect for yourself, you may send away your attendant; but until then, set as a guard over yourself the authority of some man, whether your choice be the great Cato or Scipio, or Laelius, – or any man in whose presence even abandoned wretches would check their bad impulses. Meantime, you are engaged in making of yourself the sort of person in whose company you would not dare to sin. ”

“ With regard to these two friends of ours, we must proceed along different lines; the faults of the one are to be corrected, the other's are to be crushed out. I shall take every liberty; for I do not love this one [1] if I am unwilling to hurt his feelings. "What," you say, "do you expect to keep a forty-year-old ward under your tutelage? Consider his age, how hardened it now is, and past handling! 2. Such a man cannot be re-shaped; only young minds are moulded." ”

“ You need not despair of curing sick men even when the disease is chronic, if only you hold out against excess and force them to do and submit to many things against their will. As regards our other friend I am not sufficiently confident, either, except for the fact that he still has sense of shame enough to blush for his sins. ”
