Editor's Preface Alain Badiou Thinking the Event Thesis 1: Thought is the proper medium of the universal. Thesis 2: Every universal is singular, or is a singularity. Thesis 3: Every universal originates in an event, and the event is intransitive to the particularity of the situation. Thesis 4: A universal initially presents itself as a decision about an undecidable. Thesis 5: The universal has an implicative form. Thesis 6: The universal is univocal. Thesis 7: Every universal singularity remains incompletable or open. Thesis 8: Universality is nothing other than the faithful construction of an infinite generic multiple.
