This article focuses on debates on philosophical knowledge, mathematics, and the empirical sciences by analyzing the positions on cosmological and astronomical knowledge, around 1800, of three German authors: Herder, Schelling, and Hegel. I show the mutual interdependence of Schelling’s and Hegel’s Naturphilosophie and Herder’s Ideen, and I then demonstrate that the latter’s position during the last years of his life was a reaction to Schelling’s and Hegel’s speculative philosophy. While Herder seems to ignore the works of the Naturphilosophen in his (...) journal Adrastea, in fact he participated in a very lively debate that included Schelling’s Weltseele and Hegel’s Dissertatio de Orbitis Planetarum.

In the Critique of the Power of Judgment, Kant calls purposiveness the “lawfulness of the contingent”. I argue that this should be interpreted not as lawfulness assumed in order to remove unacceptable mechanical indeterminacy, but rather as an additional kind of lawfulness which, in the case of organisms, inexplicably coincides with mechanical determination. Schelling adapts Kant’s notion of natural purposiveness in his own conception of the relation between mechanism and organism. He states in his 1798 work, On the World Soul, (...) that nature is “lawless in its lawfulness, and lawful in its lawlessness”. This should be interpreted similarly: there is a coincidence of two orders of lawfulness in nature. However, while Kant maintains that the coincidence or unity of these two orders is inexplicable for beings like us, Schelling explains the unity by assigning these laws to distinct levels of operation in nature. Organic organization is generated by a second-order operation of an organic principle on the first-order mechanical forces that are characteristic of matter. Schelling thereby builds on Kant’s third Critique framework in a creative way in order to offer a more fully unified account of nature. In this account, mechanism and organism maintain distinct roles but are both grounded in a further, higher principle. (shrink)
