jective, spoils all objectivity, and partly by professedly proving that if they were followed out to the end the principles of knowledge, taken as purely objective, led to contradictions. He had, however, hastily assumed that, apart from objective knowledge, i.e., apart from the world as idea, there is nothing given us except conscience, out of which he constructed the little that still remained of metaphysics, his moral theology, to which, however, he attributed absolutely only a practical validity, and no theoretical validity at all. He had overlooked that although certainly objective knowledge, or the world as idea, affords nothing but phenomena, together with their phenomenal connection and regressus, yet our own nature necessarily also belongs to the world of things in themselves, for it must have its root in it. But here, even if the root itself cannot be brought to light, it must be possible to gather some data for the explanation of the connection of the world of phenomena with the inner nature of things. Thus here lies the path upon which I have gone beyond Kant and the limits which he drew, yet always restricting myself to the ground of reflection, and consequently of honesty, and therefore without the vain pretension of intellectual intuition or absolute thought which characterises the period of pseudo-philosophy between Kant and me. In his proof of the insufficiency of rational knowledge to fathom the nature of the world Kant started from knowledge as a fact, which our consciousness affords us, thus in this sense he proceeded a posteriori. But in this chapter, and also in my work, "Ueber den Willen in der Natur," I have sought to show what knowledge is in its nature and origin, something secondary, designed for individual ends; whence it follows that it must be insufficient to fathom the nature of the world. Thus so far I have reached the same goal a priori. But one never knows anything wholly and completely until one has gone right round it for that purpose, and has got back to it from the opposite side from which one
