After being awarded with Master’s degree, Kant wrote his dissertation, the New Elucidation of the First Principles of Metaphysical Cognition (1755). At first glance, this work has little to do with his previous research on force, cosmos, and fire. It is about the principles of ontology, specifically the conceptual tools for metaphysical investigations. In fact, however, it was only a matter of time until he would write such a work. Now he would explore the cognitive access to dynamic interactivity and the causal structure of human integration into nature. Quite naturally, Kant moved from cosmic origins to nebulae to solar systems to planets and biota, and then to rational life. With his doctoral dissertation, Kant hoped to get to the bottom of the things that interested him most.
