Within this project, a theory of necessary and contingent existence is developed. The project’s goal is to articulate an integrated view, encompassing both a metaphysical account of what necessary and contingent existence consist in as well as an epistemological account of how necessary and contingent existence can be known. The view articulated and defended in this project can be called necessary contingentism. Necessary contingentism’s core metaphysical thesis is: everything exists contingently, but necessarily so. It is argued that this view doesn’t just offer a plausible metaphysics of modality, but is also epistemically advantageous with respect to other approaches. In articulating this view, the philosophies of Descartes, Kant, and Hegel are heavily drawn upon and brought to bear on contemporary debates.
