[The] book has a genuine intimacy to it ... [The] text displays his urgency to say more, to be clear, to keep going, to re-invent, and to express the "true life" through a generalised fidelity to his still ongoing project. * Marx & Philosophy Review of Books * In this lucid and provocative essay, one of our greatest living thinkers inquires after the meaning of happiness. Badiou argues that projects of emancipation and liberation are the surest means to an active, non-complacent contentment, although 'Happiness' is as much a spirited defense of classical philosophy as it is a call to action. We need Alain Badiou more than ever. * Tom Eyers, Associate Professor, Duquesne University, USA * What defines true happiness has been a fundamental question of philosophy since at least Plato's Republic and Aristotle's Nicomachean Ethics. Alain Badiou in this little book steals it back from the self-help industry and restores it to its metaphysical grandeur. * Bruno Bosteels, Professor of Comparative Literature and Society and Latin American and Iberian Cultures, Columbia University, USA *
