Book excerpt: in Freud's view we are driven by the desire for pleasure as well as by the desire to avoid pain. But the pursuit of pleasure has never been a simple thing. Pleasure can be a form of fear, a form of memory and a way of avoiding reality. Above all, as these essays show with remarkable eloquence, pleasure is a way in which we repeat ourselves. The essays collected in this volume explore, in Freud's uniquely subtle and accessible style, the puzzles of pleasure and morality - the enigmas of human development.
