This is the first volume focused on Markus Gabriel’s version of New Realism, which spans the fields of metaphysics/ontology, philosophy of mind, epistemology, philosophy of science, and meta-philosophy. Most of the selected contributions are directly or indirectly concerned with Gabriel’s fields of sense-ontology, his version of a thoroughly realistic pluralism. While some take up criticisms from previous debates surrounding Gabriel’s philosophy and New Realism in general, others advance completely new and innovative challenges for this highly systematic thinker. Overall, the contributions provide both a substantive commentary on Gabriel’s work and a multifaceted, critical assessment of its underlying ideas. The book is not only an essential addition to the debate surrounding New Realism, but also furthers the discussions about naturalism, deflationist ontologies, contextualism and mereological arguments to which Gabriel’s work has contributed in recent years.
