" And so the good man ought to be Self-loving: because by doing what is noble he will have advantage himself and will do good to others: but the bad man ought not to be, because he will harm himself and his neighbours by following low and evil passions. In the case of the bad man, what he ought to do and what he does are at variance, but the good man does what he ought to do, because all Intellect chooses what is best for itself and the good man puts himself under the direction of Intellect. "

― Aristotle , The Nicomachean Ethics
