This chapter addresses some key ideas of Schelling’s philosophy of nature with two main goals in mind. First, it clarifies how in Schelling’s hands, some key aspects of Kant’s philosophy of nature were transformed into a radically new philosophy of nature. Second, the chapter sheds light on some under appreciated aspects of Schelling’s philosophy of nature vis-à-vis the cultural milieu of Jena at the turn of the nineteenth century, in particular the debate surrounding the Chemical Revolution and the role of Johann Ritter in it.
