Abstract
If Wolff from the very beginning was strongly influenced by Cartesianism, and his concept of system was guided by the geometric model of scientific method, Leibniz relies on the German tradition of “methodological thinking”, originated by Joachim Jung. Leibniz’s conception of sys-tem focuses mainly on algebraic analysis. The application of the term “system” mainly to meta-physics can be explained by the fact that it is this science that deals with synthetic principles and is designed to develop a rational view of the world. Based on the idea of “real metaphysics”, Leibniz justifies these principles as such that make possible the laws of physics and rational discourse in general. Leibniz does not provide a system of philosophy in the sense of traditional school philos-ophy. He considers metaphysics as the most consistent expression of a systematic mind and indi-cates heuristic principles for the construction and improvement of reasonable hypotheses.
