“ Just as crimes occur when the mind’s motive force, which gives the impetus for action, is corrupt and asserts itself in an insolent and disturbed way, and as vicious acts occur if obsession has captured the mind’s affective part which is at the root of the impulse to carnal pleasures, so also errors and false opinions contaminate life if the reasoning mind is itself flawed. ”
 Saint Augustine, Confessions (401). copy citation
