This open access book advances the current debate in continental realism. In the field of contemporary continental ontology, Speculative Realist thinkers are now grappling with the genealogy of their ideas in the history of modern philosophy. The Speculative Realism movement prompted a debate, criticizing the predominant postmodernist orientation in philosophy, which located its origins in Kantian "correlationism" which supposedly ended the period of early modern naive realist metaphysics by showing that the mind and the outside world can only ever be understood as correlates.
