The Harmlessness of Metaphysic in the Future.—As soon as religion, art and ethics are so understood that a full comprehension of them can be gained without taking refuge in the postulates of metaphysical claptrap at any point in the line of reasoning, there will be a complete cessation of interest in the purely theoretical problem of the “thing in itself” and the “phenomenon.” For here, too, the same truth applies: in religion, art and ethics we are not concerned with the “essence of the cosmos”.⁷ We are in the sphere of pure conception. No presentiment [or intuition] can carry us any further. With perfect tranquility the question of how our conception of the world could differ so sharply from the actual world as it is manifest to us, will be relegated to the physiological sciences and to the history of the evolution of ideas and organisms.
