Biography
Matthew Davidson is Professor and Chair of Philosophy at California State University, San Bernardino. He works in metaphysics, philosophy of religion, and philosophy of language. His recent publications include The Metaphysics of Existence and Nonexistence and Knowledge and Reality in Nine Questions.
“About Haecceity makes clear the varied ties between haecceities and several on-going debates in ontology … [It] will prove a useful book for metaphysicians interested in questions about the metaphysics of identity.”
