Which theories of Leibniz are still valid after post-modern critique? Using various methods, this work considers a new interpretation and views Leibniz's work from a different perspective. As such, the authors reconstruct Leibniz's viewpoints on tolerance and truth in light of his position and the influence of church politics. Furthermore, his strategy of differentiation between animal and human will be analyzed on its usefulness to current debate. Leibniz's theory of perception will also be contrasted to comparable theories of today. The (...) usual interpretations of his metaphysics based on substance will here be contrasted by a nature-based interpretation. German text. (shrink)
