Alain Badiou's Being and Event is the most original and significant work of French philosophy to have appeared in recent decades. It is the magnum opus of a thinker who is widely considered to have re-shaped the character and set new terms for the future development of philosophy in France and elsewhere. This book has been written very much with a view to clarifying Badiou's complex and demanding work for non-specialist readers. It offers guidance on philosophical and intellectual context, key themes, reading the text, reception and influence; and further reading.
