 Turn to the most ancient and most modern philosophies: all of them lack a consciousness of the extent to which the will to truth itself needs a justification, here is a gap in every philosophy—where does it come from? Because the ascetic ideal has so far been lord over all philosophy, because truth was set as being, as god, as the highest authority itself, because truth was not allowed to be a problem. Do you understand this “allowed to be”?—From the very moment that faith in the God of the ascetic ideal is denied, there is a new problem as well: that of the value of truth.—The will to truth needs a critique—let us hereby define our own task—the value of truth is tentatively to be called into question.
