Gila Sher

Gila Sher is a professor of philosophy at the University of California, San Diego. She has worked extensively in the theory of truth and philosophy of logic. Sher is a leading advocate of foundational holism, a holistic theory of epistemology.

Sher earned a Ph.D. in philosophy from Columbia University, where she studied the works of Willard Quine and Alfred Tarski. Her dissertation was directed by Charles Parsons. Her early work focused on Tarski's definition of truth. Her reformulation of this definition has been influential in modern truth theory. Her dissertation was expanded into the book The Bounds of Logic (1991), in which Sher also formalized definitions for unique second-order quantifiers such as 'most'.

Sher has pursued research into logical positivism and logical foundationalism. She has argued that strict-ordering Foundationalism, in the vein of Rudolf Carnap, is untenable, supporting Quine's argument from Two Dogmas of Empiricism. She has, however, resisted the mainstream move toward all-or-nothing and semantic holism. The former view she considers unexplanatory, and the latter she considers untenable (see: Jerry Fodor).
