At the foundation of all the empirical positivities, and of everything that can indicate itself as a concrete limitation of man's existence, we discover a finitude which is in a sense the same: it is marked by the spatiality of the body, the yawning of desire, and the time of language; and yet it is radically other: in this sense, the limitation is expressed not as a determination imposed upon man from outside (because he has a nature or a history), but as a fundamental finitude which rests on nothing but its own existence as fact, and opens upon the positivity of all concrete limitation.
