Seneca,
Moral letters to Lucilius — Letter 120…
“ We have formed the conception that in such a man perfect virtue exists.11. We have separated this perfect virtue into its several parts. The desires had to be reined in, fear to be suppressed, proper actions to be arranged, debts to be paid; we therefore included self-restraint, bravery, prudence, and justice – assigning to each quality its special function. How then have we formed the conception of virtue? Virtue has been manifested to us by this man's order, propriety, steadfastness, absolute harmony of action, and a greatness of soul that rises superior to everything. ”
