In the popular view, according to the common notion, Nietzsche is the revolutionary figure who negated, destoyed and prophesied. To be sure, all that belongs to the image we have of him. Nor is it merely a role that he played, but an innermost necessity of his time. But what is essential in the revolutionary is not that he overturns as such; it is rather that in overturning he brings to light what is decisive and essential. In philosophy that happens always when those few momentous questions are raised. When he thinks ”the most difficult thought” at the ”peak of meditation,” Nietzsche thinks and meditates on Being, that is, on will to power as eternal recurrence. What does that mean taken quite broadly and essentially? Eternity, not as a static ”now”, nor as a sequence of nows rolling off into the infinite, but as the ”now” that bends back into itself: what is that if not the concealed essence of Time? Thinking Being, will to power, as eternal return, thinking the most difficult thought of philosophy, means thinking Being as Time. Nietzsche thinks that thought but does not think it as the question of Being and Time. Plato and Aristotle also think that thought when they conceive Being as presence, but just as little as Nietzsche do they think it as a question.
