One over Many: The Unitary Pluralism of Plato’s World is a tightly integrated collection of essays by the author, some newly drafted for the present work, some previously published as journal articles, all conceived and developed in pursuit of corrective intervention in Plato’s metaphysics. The book replaces the standard view of Plato as a metaphysical dualist with an alternative interpretation providing greater explanatory power through the paradigm of unitary pluralism in a single reality built on ontological diversity.
