Ética y acontecimiento: sobre la perspectiva sustractvista de Alain Badiou

This paper aims to highlight the main notions of Badiou's ethics, showing how the ethics proposed by the author is closely related to the notions of event and multiplicity. In this sense, it is argued that such thought exists only insofar as the subject separates from the One, from that which is considered normative. Not only are the concepts of event and multiplicity essential in the author's work, but so are the notions of infinity and mathematics, the latter being identified with ontology and granting primacy to non-being.
