I examine the relation between Henri Poincaré’s definition of mathematical continuity and Sartre’s discussion of temporality in *Being and Nothingness *and argue that Poincaré’s definition of mathematical continuity allows the for-itself to be understood both as connected to a past and future and as distinct from itself. I conclude that the gap between two terms in a temporal series comprises the present and being-for-itself, since it is this gap that occasions the radical freedom to reshape the past into a distinct and different future.
