This essay investigates thought as an event of “multiplicity.” French philosophers Gilles Deleuze and Alain Badiou pose this as a concept of change (political and otherwise). Both philosophers propose that multiplicity means thinking happens as an event by engaging a theoretical impasse, or “un-thought.” Un-thought opens up and changes ideas into complex varieties or multiplicities. This dynamic is examined through the example of May ‘68, an actual event that gives context to how multiplicity expresses “radical change.” The aim of this (...) article is to see how both thinkers’ theories overlap. For Badiou, multiplicities are “truths” that happen whilst making a decision, engaging a notion of “point.” For Deleuze, multiplicities are concepts that happen materially in life as metaphysical forces, or “lines.” Multiplicity is critically approached as a complex variety of ideas that change in the forms of art, politics, and science.
