Abstract

This thesis is a study of the relationship between Schopenhauer and the biology in the early nineteenth century. Schopenhauer improved Kant’s epistemology based on the findings of the brain physiology of the time and extended the area of the apriority and rationality. The brain paradox is based on the interpretation that Schopenhauer insists on both materialism and idealism. But what Schopenhauer received in French physiology is not materialism but vitalism. This view of Schopenhauer is also revealed by his suggesting primordial animal, which is not mechanistically explained, to Lamarck’s physicalism. Schopenhauer’s ethics does not presuppose mechanistic materialism or idealism. Schopenhauer sets the limits of natural science only to criticize the mechanical materialism. One identical being presupposed by his ethics is accepted by natural sciences.
