‘Shame presupposes that we ought to know better but flout the rules regardless. This is precisely Plato’s point about moral knowledge: we already possess it, we already know the right way to live a just and fulfilling life, but are constantly diverted from that noble aim. For Plato, then, shame is a force that helps us resist the urge to conform when we know it’s wrong to do so. Shame helps us be true to ourselves, to endure Socrates’ needling, and to heed the moral knowledge within. A man without shame, Plato says, is a slave to desire – for material goods, power, fame, respect. Such desire is tyrannical because, by its nature, it cannot be satisfied.’
