Abstract

The purpose of my study is to reconstruct the historical development of Kant's pre- critical approach to mechanical explanation and cosmology. I shall focus on three main works: the 1755 Theorie des Himmels, the 1763 Beweisgrund and the 1766 Träume. I shall challenge some interpretations of the relation between mechanism and finalism, looking for the emergence of a principle of demarcation separating both ontologically and epistemologically organics from inorganics products. I shall try to show why Kant came to be dissatisfied with his early systematic account of the formation and arrangement of the heavenly bodies on purely mechanical principles. Finally I shall argue that the pre-critical period ends, paving the way to a revision of cosmology in the light of an appreciation of the role of chemical affinity for the construction of the world-edifice
