Aristotle (c. 384-322 BCE)
“Injustice armed is hardest to deal with; and though man is born with weapons which he can use in the service of practical wisdom and virtue, it is all too easy for him to use them for the opposite purposes.”
- From Aristotle’s Politics (Bekker page 1253a), translated by T. A. Sinclair and revised by T. J. Saunders (Penguin Classics, 1962, 1981, 1992).
