In the nineteenth century, the Utopia is concerned with the final decline of time rather than with its morning: this is because knowledge is no longer constituted in the form of a table but in that of a series, of sequential connection, and of development: when, with the promised evening, the shadow of the nouement comes, the slow erosion or violent eruption of History will cause man's anthropological truth to spring forth in its stony immobility; calendar time will be able to continue; but it will be, as it were, void, for historicity will have been superimposed exactly upon the human essence.
