Nathan U. Salmon (né Nathan Salmon Ucuzoglu, 1951-) is an American philosopher in the analytic tradition, specializing in philosophy of language and metaphysics.

Biography

Salmon was born January 2, 1951 in Los Angeles to Sephardi Jews of Spanish-Turkish heritage. He is grandson of archivist Emily Sene (née Emily Perez) and oud player Isaac Sene. During his youth Salmon tried unsuccessfully to believe in the Judeo-Christian God. Finding Russell's teapot spiritually unfulfilling as an alternative to theism, Salmon eventually converted to the Church of FSM. A self-taught, semi-professional guitarist, Salmon learned much of what he knows of music theory while in middle school from his boyhood friend, music prodigy James Newton Howard. Salmon attended El Camino College and the University of California, Los Angeles (UCLA).

At UCLA Salmon studied with leading philosophers/logicians Tyler Burge, Alonzo Church, Keith Donnellan, Donald Kalish, David Kaplan, Saul Kripke, and Yiannis Moschovakis. Salmon earned his Ph.D. in 1979 while he was assistant professor of philosophy at Princeton University. Salmon's first book, Reference and Essence (his UCLA doctoral dissertation) won the 1984 Gustave O. Arlt Award in the Humanities, awarded by the Council of Graduate Schools in the United States. Salmon is currently distinguished professor of philosophy at the University of California, Santa Barbara, where he has taught since 1984.

Work

Summary

In philosophy of language Salmon defends the theory of direct reference. He has provided direct-reference accounts both of propositional attitudes and of Frege's puzzle about true identifications, i.e., truths of the form "a = b" (in his books, Frege's Puzzle and Content, Cognition, and Communication). In addition he has provided direct-reference accounts of problems of nonexistence and of names from fiction. In particular Salmon is known for his solution, compatible with direct reference, to the traditional problem of true, negative existentials, i.e., truths of the form "a does not exist" (Metaphysics, Mathematics, and Meaning). Salmon argues, directly contrary to Immanuel Kant, that existence is a property, one that particular individuals have and other individuals lack. According to Salmon, the English verb "exist" is (among other things) a term for this alleged property, and a sentence of the form "a exists" is false (and "a does not exist" is true) if and only if the subject term designates something that has the complementary property of nonexistence. Thus Russell's example, "The present king of France exists", is neither true nor false, since France is not presently a monarchy, and therefore "the present king of France" does not designate; whereas "Napoleon exists" is simply false, since although Napoleon once existed, the moment he died he took on the property of nonexistence.

By contrast, Salmon maintains that "Sherlock Holmes exists" is literally true, whereas "Sherlock Holmes was a detective" is literally false. According to Salmon, Sherlock Holmes is an abstract entity created by author Arthur Conan Doyle, and the fiction is a collection of stories, which are literally false of that very character. Holmes really exists, but he is only a fictional detective, not a real one. Salmon extends this view to mythical objects, like the hypothetical planet, Vulcan. Vulcan really exists, but it is only a mythical planet, not a real one.

Salmon maintains, again contrary to Kant, that it is completely legitimate to invoke existence in a term's definition. Thus "God" might be legitimately defined as the conceivable individual that is divine and also exists. But, according to Salmon, the ontological argument for God's existence fallaciously assumes that "The F is F" is an analytic truth. What is analytic is a significantly weaker variant: "If anything is uniquely F, then the F is F". The strongest conclusion that validly follows from the proposed definition is that if any conceivable individual actually is uniquely both divine and existent, then God actually exists. This same conclusion is also a trivial logical consequence of the atheist's contention that no conceivable individual actually is uniquely both divine and existent. The ontological argument thus shows nothing.

Salmon argues that natural-language sentences that are representable as λ-converts of one another (in the sense of Church's lambda-calculus) are, although logically equivalent by λ-conversion, typically not strictly synonymous, i.e., they typically differ in semantic content--as for example "a is large and also a is seaworthy" and "a is a thing that is both large and seaworthy".

Salmon maintains a sharp division between semantics and pragmatics (speech acts). He argues that in uttering a sentence, a speaker typically asserts a good deal more than the words' semantic content, and that, consequently, it is a mistake to identify the semantic content of a sentence with what is said by its speaker. Salmon maintains that such an identification is an instance of a mistaken form of argument in the philosophy of language, "the pragmatic fallacy."

Salmon is also known in metaphysics for, among other things, his analysis of arguments for essentialism, and in particular for his development and defense of a reductio ad absurdum argument, using a sorites-like problem, against nearly universally accepted modal logic systems S4 and S5, which he argues commit "the fallacy of necessity iteration" (Reference and Essence and Metaphysics, Mathematics, and Meaning). He also provided a reductio ad absurdum argument against the logical coherence of the philosophically popular idea of indeterminate identity, i.e., that for some pairs of objects there is no fact of the matter concerning whether those objects are one and the very same. (Reference and Essence and Metaphysics, Mathematics, and Meaning).

Salmon's primary influences are philosophers/logicians Alonzo Church, Gottlob Frege, David Kaplan, Saul Kripke, and Bertrand Russell.
