This article brings Leibniz' metaphysics down to earth. The long sought genesis of thinking is based on the organic nature. Leibniz' metaphysics is comprehensible as universal, because it links logic with the ontological fundamentals of the real. The paradox of individual substance is solvable. Herefore fact and concept of thinking are to be stretched towards acting, self-evolution as well as becoming self-conscious. So individual substance becomes the principle of organic nature, of becoming self-conscious, of historicity as well as the principle (...) of person — by the very structure. The opposites of belief and knowledge, of nature and history can be derived from the same principle. All human beings, all living beings are inseparably linked by their common structure. They differ though in the various informations and contents which flow in this structure. (shrink)
