What People are Saying About This

From the Publisher

"The decades of research since Identity and Discrimination was first published have shown how badly a theory of indiscriminability is needed for understanding a wide range of philosophical problems. Williamson's discussion has numerous  applications in metaphysics, epistemology, and the philosophy of mind."

—Susanna Siegel, Harvard University

"This is the first book of one of our greatest philosophers. Unrelenting in his clear, thorough style, Williamson presents a groundbreaking epistemic account of indiscriminability. The unified vision underlying some of Williamson's best-known subsequent work—-on vagueness, identity, and knowledge—-emerges here."

—Delia Graff Fara, Princeton University
