This essay reconstructs the steps by which Cassirer moved from the philosophy of language in the early 1920s to his more general theory of symbolism. The linguistic turn in philosophy overcame idealism without falling into naturalism or psychologism, but according to Cassirer proclaiming the primacy of language was one-sided. He claimed that language is but one symbolic form among many and, what is more, it is not the most fundamental kind of symbolism. The basic function of symbolism is neither “reference” (...) nor “pure signification,” but the unification of sensory phenomena in perception, a function he termed symbolic “Prägnanz.” The essay explains how Cassirer argued for a continuity of symbolic processes linking expressive perceptual qualities with scientific theory.

Does epistemology collapse for lack of resources other than logic, conceptual analysis and descriptions of one’s own apparent experiences, thoughts and beliefs? No, but understanding how and why not requires, Kant noted, a ‘changed method of thinking’. Some of these methodological changes are summarised in §2 in order to identify a philosophical role for thought experiments to help identify logically contingent, though cognitively fundamental capacities and circumstances necessary to human thought, experience and knowledge. As Kant also noted, experiments are only (...) informative in response to posing the right question, indeed: the right kind of question. Accordingly, preparations for these epistemological thought experiments fill half of this chapter. The second half, examines three such thought experiments, variously developed by Kant, Hegel, C. I. Lewis, Austin, Wittgenstein and F. L. Will. (shrink)
