And on fluenced, at least in part, by his study at that time of the writings of the view of language that is presented in at least some of these writings, the behavioral psychologist J. B.

These doubts only came of acquaintance”—understanding a sentence requires being acquainted to a head, however, in the early 1950s, with the appearance with the entities corresponding to the words in that sentence, and a of Wittgenstein’s Philosophical Investigations, Austin’s mock- central task of philosophy consists in analyzing the meanings of our ery of “the ontology of the sensible manifold,” and Sellars’s sentences concerning physical objects, given that we are not acquainted “Empiricism and the Philosophy of Mind”, with such objects. Moreover, against the background of this understanding of Rus- but also his views of meaning: sell’s philosophy, it is natural to regard some of the major figures in The distinction between the necessary and contingent—re- post–World War II analytic philosophy—including, for example, the vitalized by Russell and the Vienna Circle as the distinction later Wittgenstein, Quine, Austin, and Sellars—as seeking to under- between “true by virtue of meaning” and “true by virtue mine characteristic features of Russell’s position. This familiar view is of experience”—had usually gone unchallenged, and had reflected, for example, in Richard Rorty’s 1979 book Philosophy and the formed the least common denominator of “ideal language” Mirror of Nature. There Rorty presents Russell, along with Husserl, as and “ordinary language” analysis. However, also in the seeking, in different ways, to establish philosophy as the foundational early fifties, Quine’s “Two Dogmas of Empiricism” challenged discipline, which through its knowledge of “apodictic truths” (Russell’s this distinction, and with it the standard notion (common “logical forms”, Husserl’s “essences”) is able to assess the standing of to Kant, Husserl, and Russell) that philosophy stood to em- other disciplines. According to Rorty, pirical science as the study of structure to the study of con- . the kind of philosophy which stems from Russell and tent. Given Quine’s doubts (buttressed by similar doubts in Frege is, like classical Husserlian phenomenology, simply Wittgenstein’s Investigations) . , it became difficult to ex- one more attempt to put philosophy in the position which plain in what sense philosophy had a separate “formal” field Kant wished it to have—that of judging other areas of cul- of inquiry and thus how its results might have the desired ture on the basis of a special knowledge of the “founda- apodictic character. (Ibid., 169) tions” of these areas. (1979, 8) According to Rorty, these challenges to Russell’s views of acquaintance along with his views of meaning “were challenges to the views idea of And the “story” Rorty “want[s] to tell” (ibid., 168) is how such founda- a ‘theory of knowledge,’ and thus to philosophy itself, conceived of as a tionalist aspirations of Russell and Husserl were called into question by discipline which centers around such a theory” (ibid.). their successors: Recently, there has been a growing awareness that Russell’s post– [I]n the end, heretical followers of Husserl (Sartre and Hei- 1918 writings call into question the sort of picture that Rorty presents degger) and heretical followers of Russell (Sellars and Quine) of the relation of Russell’s philosophy to the views of subsequent figures raised the same sorts of questions about the possibility of such as the later Wittgenstein, Quine, and Sellars. For an examination apodictic truth which Hegel raised about Kant, (ibid., 167) of those writings shows that by the early 1920’s Russell himself was advocating views—including an anti-foundationalist naturalized epis- thereby undermining the view of philosophy as having a preeminent, temology, and a behaviorist–inspired account of what is involved in un- privileged status. More specifically, for Rorty, Russell’s mid–century suc- derstanding language—that are more typically associated with philoso- cessors attacked not only his views of acquaintance and his sense-data phers from later decades whom Rorty presents as dismantling Russell’s epistemology: philosophy. www.thebalticyearbook.org Vol. 4: 200 Years of Analytical Philosophy 5 James Levine From Moore to Peano to Watson 6 Hence, Thomas Baldwin begins his 2003 paper “From Knowledge Numerous passages support these claims of Baldwin and Dreben.2 Thus, by Acquaintance to Knowledge by Causation” by writing: for example, in his 1924 paper “Logical Atomism”, Russell writes: There are many familiar themes in Russell’s repertoire, but I began to think it probable that philosophy had erred in his later discussions of knowledge include many insights adopting heroic remedies for intellectual difficulties, and which have received little notice.
