Analytic Philosophy in America
The leading preanalytic philosopher in America, and one of its giants of all time, was Charles Sanders Peirce (1839â1914). Having received a scientific education (including a Harvard BS in chemistry in 1863), he lectured on logic and philosophy of science at Harvard (1864â65, 1869â71) and Johns Hopkins (1879â84), after which he moved to Milford, Pennsylvania, where he continued to write prodigiously. His greatest contributions were in logic, including a syntax for quantification theory (1870) and (1883), and a truth-functionally complete system based on what later came to be called âthe Sheffer stroke.â Though his contributions were, in many respects, parallel to those of Gottlob Frege, the two logicians worked independently, with the writing of Frege, through its influence on Bertrand Russell, becoming the more widely known. Still, Alfred North Whitehead was an admirer whose knowledge of quantification theory was said to have come substantially from Peirce, while Hilary Putnam (1982) observed that much that is âquite familiar in modern logic actually became known to the logical world through the efforts of Peirce and his students.â In 1985, W.V.O. Quine identified Peirce as sharing credit with Frege for the development of modern quantification theory, and cited his influence on Ernst Schröder and Giuseppe Peano.
Outside of logic, Peirceâs philosophy of pragmatismâor, as he called it, âpragmaticismââwas widely admired. In epistemology, he was an antifoundationalist, resisting the idea of a privileged starting point of maximally certain statements (e.g., of private sensation) and adopting, as a guiding hypothesis, the idea that the application of scientific method to intersubjectively verifiable claims would, through a process of self-correction, lead different investigators to converge on a common result, no matter what their starting points. While not definitively identifying truth with that which would be confirmed in the limit of ideal (scientific) inquiry, Peirce did think that the practical consequences of true beliefs provided grounds for expecting them to be confirmed by continuing investigation. Correspondingly, he took the meaning of a theoretical claim to be its experiential âcash valueââthe collection of possible empirical observations that would verify it. He had little patience with metaphysical speculation about âthings in themselvesâ underlying observed phenomena, or grand metaphysical systems. In all these ways, Peirce exerted a strong influence on those who would follow. Peircean reverence for logic, respect for science, suspicion of apriori metaphysics, and emphasis on the practical consequences of theoretical differences found fertile soil and took root in America, creating a hospitable environment for the later growth, and distinctive shape, of analytic philosophy there.
The other great American pragmatist was William James (1842â1910). Like Peirce, James had a scientific education in chemistry, anatomy, and medicine at Harvard, where he received an MD in 1869. He taught physiology in 1872, and in 1875 he set up the first laboratory for experimental psychology in America. Between 1885 and 1907 he was professor of psychology and philosophy at Harvard, during which period he gave The Varieties of Religious Experience (1902) as the Gifford Lectures at Edinburgh, and published Pragmatism in 1907. Though influenced by Peirce, Jamesâs outlook was less scientific, and his audience broader. Whereas for Peirce truth and meaning rested on the intellectual foundation of possible observation, for James they rested on what it is beneficial to believe. To the extent that religious beliefs help us live better lives, they pass the Jamesian pragmatic test for truth, just as scientific beliefs do.
Third in the trio of preanalytic pragmatists was John Dewey (1859â1952), who earned his PhD in philosophy from Johns Hopkins in 1884, where he encountered Peirce. Between 1884 and 1930, Dewey taught at the Universities of Michigan, Minnesota, Chicago, and (for the last twenty-four years) at Columbia. Like Peirce, he was an antifoundationalist and believer in the self-correcting nature of empirical investigation in a community of inquirers. Like Quine, who was to follow, he held that there are no absolute first principles that are either known with certainty or beyond rational revision in light of new experience. Truth, for Dewey, was warranted assertability. Though less influential than Peirce in the later development of analytic philosophy, Deweyâs views on education, and other social issues, had a large and controversial impact.
Along with pragmatism, realism and naturalism characterized much American philosophy between Peirce and Quine. Peirce wrote in 1896, âNothing can be more completely false than that we can experience only our own ideas. That is indeed without exaggeration the very epitome of all falsityâ (Peirce, CP 6.95). The independence of the perceived from the perceiver, and the known from the knower, was emphasized in The New Realism (1912) by philosophers such as Edwin Bissell Holt and Ralph Barton Perry. As John Passmore (1957) noted, their conception of perception was similar to that given in George Edward Mooreâs âThe Refutation of Idealismâ (1903), while their rejection of âinternal relationsâ paralleled a similar rejection, central to the rebellion of Moore and Russell against absolute idealism. (The importance of the rejection for New Realists was in their observation that when a knows b, the relational properties of knowing b, and of being known by a, are not essential to a and b, respectively.) By 1920, another brand of realism, Critical Realism, was on the scene. Advocated by Arthur Oncken Lovejoy, George Santayana, and Roy Wood Sellars, among others, it struggled to reconcile the objective physical world, revealed in perception, with an irreducible Kantian residue added by the perceiver to the content of experience. Although disputes between these varieties of realism have now lost much of their force, it is striking how congenial the broad themes of naturalism, respect for science and common sense, and suspicion of idealism and other apriori speculation were to the growth of analytic philosophy in America.
THE TRANSITION TO ANALYTIC PHILOSOPHY
The American transition to analytic philosophy was mediated by several pivotal figures, institutions, and events. One such figure was Morris Cohen (1880â1947). Born in Russia, educated at City College of New York, with a 1906 Harvard PhD, he taught at City from 1912 to 1938, and at the University of Chicago from 1938 to 1941. Known for his interest in logic and the philosophy of science, he was a committed naturalist who recognized no nonscientific methods capable of attaining knowledge in philosophy. One of his students was the Czechoslovakian born Ernest Nagel (1901â85), who, after earning his BA at City, got his PhD in 1931 (under Dewey) from Columbia, where (with the exception of a year at Rockefeller University in the 1960s) he spent his career teaching and writing about the philosophy of science, and explaining the centrality of logic to philosophy. His little book, Gödelâs Proof (1958) coauthored with James R. Newman, introduced the incompleteness theorems to many students, while his main work, The Structure of Science (1961), summed up the results of decades of teaching and research on the nature of explanation, and the logical structure of scientific knowledge.
Of all the transitional figures, the greatest was C. I. Lewis (1883â1964). While earning his BA (1905) and PhD (1910) from Harvard he worked with, and was influenced by, William James, Josiah Royce, and Ralph Barton Perry. After teaching at Berkeley for nine years, he returned to take a position at Harvard in 1920, from which he retired thirty-three years later, having taught many who would become leading analytic figuresâincluding Quine, Roderick Chisholm, Roderick Firth, William Frankena, Nelson Goodman, and Norman Malcolm. He finished his career at Stanford University in 1960. An eclectic thinker and system-builder, Lewis combined an element of perceptual realism, filtered through Perry; a Kantian element, filtered through Josiah Royce; and a pragmatic element, filtered through Peirce (whose work he encountered when given the job of cataloging the latterâs vast unpublished writings). Like Perry, Lewis believed that perception and knowledge require an independent reality given in experience. Like Royce he was convinced that experience is the result of structuring and interpreting the given in terms of âaprioriâ concepts added by the mind. Like Peirce, Lewis held that (i) our conceptsâeven the âaprioriâ onesâare not fixed by the nature of the mind but are revisable in light of experience, and (ii) the meanings of concepts, thoughts, and experience lie in their pragmatic success in anticipating and predicting new experience and grounding successful action. These ideas were worked out in his two major works, Mind and the World Order (1929) and An Analysis of Knowledge and Valuation (1946), which were among the most widely read of their dayâthe former being the subject of a memorable seminar at Oxford led by J. L. Austin and Isaiah Berlin in the 1936â37 academic year.
Lewisâs relation to the logical positivists was ambiguous. He shared their scientific naturalism, their emphasis on logical analysis, and their view of testable consequences as the basis of empirical significance, but he vigorously opposed their noncognitivism about value, their physicalism, and their embrace of âthe linguistic turn.â For him, the primary bearers of meaning and truth were mental: thoughts, concepts, and experiences. Of most importance for analytic philosophy was his pioneering work in modal logic, included in his widely read Symbolic Logic (1932), coauthored with Cooper Harold Langford. Lewisâs main contribution was in formulating a series of increasingly strong axiomatic systems (the S-systems) of the modal propositional calculus (with operators for necessity and possibility)âwhich provided the basis for (i) later axiomatic extensions to the predicate calculus by Ruth Marcus (1946) and Rudolf Carnap (1946), (ii) the fledgling semantic treatment in Carnap (1947), and (iii) the revealing model-theoretic interpretations of the S-systems in Saul Kripke (1959) and (1963). For Lewis, the philosophical moral drawn from the competing axiomatic systems was that logical first principles are not decidable apriori but must be judged by their pragmatic successâa conclusion that, no matter what its ultimate merits, was premature in light of later work. Finally, the distinction in Lewis (1946) between the different âmodes of meaning of a termââ(i) its extension, consisting of things to which it refers or applies; (ii) its âcomprehensionâ (now called its âintensionâ), consisting of a mapping of possible world-states to extensions; and (iii) its âsignification,â consisting of a concept or property determining (ii)âwas an important forerunner of later developments in analytic philosophy of language.
In understanding the transition to the analytic period in America, it is important to remember that analytic philosophy is not a fixed body of substantive doctrine, a precise methodology, or a radical break with most traditional philosophy of the pastâsave for varieties of romanticism, theism, and absolute idealism. Instead, it is a discrete historical tradition stemming from Frege, Moore, Russell, Wittgenstein, and the logical positivists, characterized by respect for science and common sense, belief in the relevance of logic and language for philosophy, emphasis on precision and clarity of argumentation, suspicion of apriori metaphysics, and elevation of the goals of truth and knowledge over inspiration, moral uplift, and spiritual comfortâplus a dose of professional specialization. All these tendencies were already present in Americaâpreeminently at Harvard, but also at Columbia, City College of New York, the University of Michigan, and other environs. They were reinforced by repeated visits to America to teach and lecture by Moore (1940â44) and Russell (1896, 1914, 1924, 1927, 1929, 1931, 1938, 1939, 1940â42), and the addition to the Harvard philosophy faculty in 1924 of the coauthor of Principia Mathematica, Alfred North Whitehead. Each had a noticeable impact on the locals. For example, Quineâwhose ...
