Rh back to a completely incomprehensible miracle, and then leaves it beside it, or rather leaves it to begin from it. For every definite, inexplicable force of nature which lies at the foundation of the most different kinds of effects of an unorganised body, not less than the vital force which manifests itself in every organised body, is such an incomprehensible miracle, as I have fully explained in chap. 17, and have also shown that physics can never be set upon the throne of metaphysics, just because it leaves quite untouched the assumption referred to and also many others; whereby from the beginning it renounces all claim to give an ultimate explanation of things. I must further remind the reader here of the proof of the insufficiency of materialism, which is given towards the end of the first chapter, because, as was said there, it is the philosophy of the subject which forgets itself in its calculation. But all these truths rest upon the fact that everything objective, everything external, since it is always only something apprehended, something known, remains also always indirect and secondary, therefore absolutely never can become the ultimate ground of explanation of things or the starting-point of philosophy. Philosophy necessarily requires what is absolutely immediate for its starting-point. But clearly only that which is given in self-consciousness fulfils this condition, that which is within, the subjective. And hence it is so eminent a merit of Descartes that he first made philosophy start from self-consciousness. Since then, upon this path, the genuine philosophers, especially Locke, Berkeley, and Kant, have gone even further, each in his own manner, and in consequence of their investigations I was led to recognise and make use, not of one, but of two completely different data of immediate knowledge in self-consciousness, the idea and the will, by the combined application of which one can go further in philosophy, in the same proportion as in the case of an algebraical problem one can accomplish more if two known quantities are given than if only one is given.
