Like Einstein’s universe, it is both boundless and finite. Boundless: it runs back through time and space to the very beginnings of the world and to its utmost limits. In my being I sum up the earthly inheritance and the state of the world at this moment.

And yet life is also a finite reality. It possesses an inner heart, a centre of interiorization, a me which asserts that it is always the same throughout the whole course. A life is set within a given space of time; it has a beginning and an end; it evolves in given places, always retaining the same roots and spinning itself an unchangeable past whose opening toward the future is limited. It is possible to grasp and define a life as one can grasp and define a thing, since a life is “an unsummed whole,” as Sartre puts it, a detotalized totality, and therefore it has no being. But one can ask certain questions about it.
