Plato, Letters 335b

in soul listens not, or if he listens he laughs them (as he thinks) to scorn, while he shamelessly plunders from all quarters everything which he thinks likely to provide himself, like a beast, with food or drink or the satiating himself with the slavish and graceless pleasure which is miscalled by the name of the Goddess of Love ; for he is blind and fails to see what a burden of sin—how grave an evil—ever accompanies each wrong-doing; which burden the wrong-doer must of necessity drag after him both while he moves about on earth
