not be contained in the world itself, but must be sought for only outside the world in something we can only attain to under the guidance of those forms of which we are conscious a priori. But so long as this is not proved, we have no grounds for shutting ourselves off, in the case of the most important and most difficult of all questions, from the richest of all sources of knowledge, inner and outer experience, in order to work only with empty forms. I therefore say that the solution of the riddle of the world must proceed from the understanding of the world itself; that thus the task of metaphysics is not to pass beyond the experience in which the world exists, but to understand it thoroughly, because outer and inner experience is at any rate the principal source of all knowledge; that therefore the solution of the riddle of the world is only possible through the proper connection of outer with inner experience, effected at the right point, and the combination thereby produced of these two very different sources of knowledge. Yet this solution is only possible within certain limits which are inseparable from our finite nature, so that we attain to a right understanding of the world itself without reaching a final explanation of its existence abolishing all further problems. Therefore est guadam prodire tenus, and my path lies midway between the omniscience of the earlier dogmatists and the despair of the Kantian Critique. The important truths, however, which Kant discovered, and through which the earlier metaphysical systems were overthrown, have supplied my system with data and materials. Compare what I have said concerning my method in chap. xvii. of the Supplements. So much for the fundamental thought of Kant; we shall now consider his working out of it and its details.
Kant's style bears throughout the stamp of a pre-eminent mind, genuine strong individuality, and quite
