What emerges from these separate strands of (modern) history is an image of man himself that bears a new, stark, more nearly naked, and more questionable aspect. The contraction of man's horizons amounts to a denudation, a stripping down, of this being who has now to confront himself at the center of all his horizons. The labor of modern culture, whenever it has been authentic, has been a labor of denudation. A return to the sources; "to the things themselves," as Husserl puts it; toward a new truthfulness, the casting away of ready-made presuppositions and empty forms - these are some of the slogans under which this phase in history has presented itself. Naturally enough, much of this stripping down must appear as the work of destruction, as revolutionary or even "negative": a being who has become thoroughly questionable to himself must also find questionable his relation to the total past which in a sense he represents.
