We are ambivalent, in Freud’s view, about anything and everything that matters to us; indeed, ambivalence is the way we recognise that someone or something has become significant to us. This means that we are ambivalent about ambivalence, about love and hate and sex and pleasure and each other and ourselves, and so on; wherever there is an object of desire there must be ambivalence. But Freud’s insistence about our ambivalence, about people as fundamentally ambivalent animals, is also a way of saying that we’re never quite as obedient as we seem to be: that where there is devotion there is always protest, where there is trust there is suspicion, where there is self-hatred or guilt there is also self-love. We may not be able to imagine a life in which we don’t spend a large amount of our time criticising ourselves and others; but we should keep in mind the self-love that is always in play. Self-criticism can be our most unpleasant – our most sadomasochistic – way of loving ourselves.
