Kant's Inaugural Dissertation and the Problem of Rational Cosmology

Abstract:Kant's 1770 Dissertation is surprisingly rarely read as a cosmological treatise about the "world." The few commentators who do so invariably claim that, in the fourth section of the work, Kant presents a purely intellectual cosmology, a relic of dogmatic, Leibnizian-Wolffian metaphysics. This article aims to show that attention to some often-overlooked passages yields a very different picture. Key to how Kant conceives of the form of the world is his distinction between the relations of co-ordination and subordination of substances. On the basis of this distinction, the author argues that the "principle of the form of the intelligible world" does not pertain to a transcendent intelligible world. Instead, the principle concerns an intellectual perspective on the world of substances co-ordinated in space and time. This interpretation has various consequences for our understanding of the development of Kant's critical philosophy.
