Again, if the world is destroyed, it must needs either be destroyed according to nature or against nature. Against nature is impossible, for that which is against nature is not stronger than nature. If according to nature, there must be another nature which changes the nature of the world: which does not appear.
SallustSmall endeavours obtain strength by unity of action: the most powerful are broken down by discord.
SallustWhile the body is young and fine, the soul blunders, but as the body grows old it attains its highest power. Again, every good soul uses mind; but no body can produce mind: for how should that which is without mind produce mind? Again, while the soul uses the body as an instrument, it is not in it; just as the engineer is not in his engines (although many engines move without being touched by any one).
SallustSouls that have lived in virtue are in general happy, and when separated from the irrational part of their nature, and made clean from all matter, have communion with the gods and join them in the governing of the whole world. Yet even if none of this happiness fell to their lot, virtue itself, and the joy and glory of virtue, and the life that is subject to no grief and no master are enough to make happy those who have set themselves to live according to virtue and have achieved it.
SallustThe soul sins therefore because, while aiming at good, it makes mistakes about the good, because it is not primary essence. And we see many things done by the Gods to prevent it from making mistakes and to heal it when it has made them. Arts and sciences, curses and prayers, sacrifices and initiations, laws and constitutions, judgments and punishments, all came into existence for the sake of preventing souls from sinning; and when they are gone forth from the body, Gods and spirits of purification cleanse them of their sins.
