Keith Hossack is a contemporary British analytic philosopher known for his work in metaphysics, the philosophy of mathematics, and epistemology. He has developed systematic accounts of abstract objects, facts, and the metaphysics of knowledge, with particular attention to how abstract entities like numbers and propositions relate to concrete reality.
