Anil K. Gupta (born 1949) is an Indian-American philosopher who works primarily in logic, philosophy of language, metaphysics, and epistemology. Gupta is the Alan Ross Anderson Distinguished Professor of Philosophy at the University of Pittsburgh. He is also a Fellow of the American Academy of Arts and Sciences.[1]

Biography

Gupta earned his B.Sc. with first class honours from the University of London in 1969. He then attended the University of Pittsburgh where he received his M.A. (1973) and Ph.D. (1977). Gupta has taught at several universities: McGill University (1975-1982), University of Illinois at Chicago (1982-1989), Indiana University (1989-2000).[2] In 2001 Gupta joined the Department of Philosophy at the University of Pittsburgh where he served as Distinguished Professor of Philosophy and, since 2013, as Alan Ross Anderson Chair.[3]

Revision theory

Main article: Revision theory

Gupta developed an early version of the revision theory of truth.[4] Later he generalized this to a theory of circular and interdependent definitions.[5] This work was further developed, resulting in the book, The Revision Theory of Truth, co-written with Nuel Belnap.

The revision theory is a semantic theory of truth that combines an unrestricted truth predicate with classical logic.[6] Revision theory takes truth to be a circular concept, defined by the Tarski biconditionals,

`A' is true if and only if A,

and interprets it in a new way. Rather than interpret the truth predicate via a single extension, as is done with non-circular predicates, revision theory interprets it via a revision process. The revision process is a collection of revision sequences that result when arbitrary hypotheses concerning the interpretation of truth are revised using a rule provided by the Tarski biconditionals. In the revision process, problematic sentences such as the Liar (“this very sentence is not true”) do not settle on a definite truth value. Remarkably, however, ordinary unproblematic sentences do receive a definite truth value. If problematic types of cross-reference are eliminated from the language, then the revision process converges to a fixed point.

Gupta has applied revision theory to rational choice in game theory, building on the work of André Chapuis.[7]

Gupta has recently applied the informal ideas of revision theory to problems arising in the philosophy of perception.[8]

Experience and Reformed Empiricism

In Empiricism and Experience, Gupta proposes a novel empiricist account of the logical relation between perceptual experience and knowledge.[9][10][11]

The problem Gupta addresses is that of explaining the role of experience in making our views and, in particular, perceptual judgments rational. Gupta’s proposal is that the given in experience is hypothetical.[12] Rather than providing perceptual judgments with categorical rationality, experience confers on these judgments a conditional rationality. A perceptual experience, according to Gupta, makes a subject’s judgment rational if the subject’s antecedent view is rational.[13] An antecedent view is the collection of beliefs, conceptions, and concepts that the subject of an experience brings to bear on the experience.

Gupta uses the notion of the hypothetical given to build a reformed empiricism. He argues that this empiricism has significant advantages over the traditional versions of the view.[14] Among other features, Gupta’s empiricism does not require the acceptance of an anti-realism about commonsense and theoretical objects, and it does not rely on the analytic-synthetic distinction to do any substantive work. Finally, Gupta argues that his reformed empiricism incorporates plausible components of both foundationalism and coherentism.[15]
