The introduction considers where philosophy is engaged before, for a first time, mention is made of a relation between a concept and an event. The time of the incipit turns toward, and no sooner, away from a founding topos or "place" of philosophy – "that to philosophize is to learn to die" – into a spatial and variation. The sole events are expositions and the sole concepts productions that can be sold. For a first time in the discourse, albeit in a negative cast, Gilles Deleuze tenders a relation that a concept holds with an event and, by implication, the suggestion that a passage to and from the one and the other gives birth to space. By way of truncated conclusion it can be said that from Deleuze's reflections on philosophy where concepts and events are related there emerges a sense of an amorphous but also pliant, resilient and protean space.
