At foundation level, the four segments of the theory of discourse are still to be found: as in the Classical age, they still serve in this new analytic of the human being to express the relation to things; but this time the modification is the inverse of what it was previously; it is no longer a matter of replacing them in a space interior to language, but of freeing them from thedomain of representation within which they were trapped, and of bringing them into play in that dimension of exteriority in which man appears as a finite, determined being, trapped in the density of what he does not think, and subject, in his very being, to the dispersion of time.
