In this ambitious new book, Terry Eagleton, one of the world's greatest cultural theorists, turns his attention to the now much-discussed question of ethics. In a work full of rare insights into tragedy, politics, literature, morality and religion, Eagleton investigates ethical theories from Aristotle to Alain Badiou and Slavoj Zizek, weighing the merits and deficiencies of each theory, and measuring them all against the 'richer' ethical resources of socialism and the Judaeo-Christian tradition. In a remarkably original move, he assigns each of the theories he examines to one or other of Jacques Lacan's three psychoanalytical categories of the Imaginary, the Symbolic and the Real, and shows how this can illuminate the strengths and weaknesses of an ethics of personal sympathy, an impersonal morality of obligation, and a morality based on death and transformation.
