"Badiou by Badiou synthesizes Badiou's key ideas with a personal touch, inviting readers into his presentation of what philosophy is and his highly original way of philosophizing. Badiou is brilliant at making anyone want to engage with philosophical questions."—Emily Apter, author of Unexceptional Politics "This book captures the latest developments in Alain Badiou's thought, while providing an excellent introduction for new readers. Badiou by Badiou, his most legible work, is a riveting tour of the domains of art, love, politics, and science."—Héctor Hoyos, author of Things with a History "Badiou proves himself again to be, like Socrates, a corrupter of the youth. With this clear entry point into his metaphysical project, Badiou demonstrates the dangerously transformative character of philosophy."—Jodi Dean, author of Comrade "As the 21st century shapes up to be all about ends, Badiou challenges us to think ab novo. This latest installment of his firebrand philosophy will ignite youth even among those who think its time has passed."—Joan Copjec, author of Imagine There's No Woman
