Abstract

In his book from 1799 "Einleitung zu dem Entwurf eines Systems der Naturphilosophie" Schelling defines philosophy of nature (Naturphilosophie) as science of nature (Wissenschaft der Natur) a priori but emphasises nonetheless the importance of experience to develop such a science of nature. This raises the problematical question of how this science of nature as an science a priori that has concrete phenomena (Naturerscheinungen) as it's objects can be possible. In this text the author argues that it is Schelling's critical concept of system respective systematicity of nature itself that allows him to develop a (philosophical) system of nature that for us might be known through experience but - as systematical knowledge - must be considered as necessary and therefor a priori.
