This chapter presents Alain Badious future work in philosophy. Badious own work has shifted markedly from his early work up to Theory of the Subject, before creating the most significant rupture in his own oeuvre with Being and Event. Primary are Natacha Michel, Sylvain Lazarus, Judith Balso, as well as Barbara Cassin, whose Leffet sophistique has proven highly provocative for Badiou. In his reconstruction of a contemporary Platonism, Badious philosophy has clearly already had significant effects on himself, as on philosophy more generally. Badious central and overarching question concerns how the new appears in being. To think the new in situations whose impossibility is always existent and whose chance is given in the event that it has happened is the demand that falls to philosophy. Philosophy, for Badiou, is the desire to continue in thought that which from time to time manifests itself without predicate and against all odds.
