Aristotle (c. 384-322 BCE)
“As a matter of fact, every bad man is ignorant of what he ought to do and refrain from doing, and it is just this sort of fault that makes people unjust and generally bad.”
- From The Nicomachean Ethics (Bekker number 1110b) by Aristotle, translated by J. A. K. Thomson (Penguin Classics, 2004).
