Wittgenstein's lectures in 1930–33

Abstract

The transition from early to middle Wittgensteinian thought involves a rejection of the Tractatus account of “elementary” propositions and the assumption that all general propositions are truth-functional logical products. An ultimate analysis of language is conceptually unattainable, as the distinction between atomic and molecular propositions depends upon grammatical definitions rather than a hidden logical structure. In mathematics, infinite series and recursive proofs function as rules or limits rather than exhaustive enumerations, implying that the sense of mathematical existence is determined by the specific method of proof. Similarly, the grammar of sensation reveals a fundamental asymmetry between first-person “primary experience” and third-person behavioral observation; the term “I” in reports of pain does not denote a physical possessor and bypasses standard verification criteria. Aesthetic and ethical discourse provides descriptive reasons to facilitate a “synopsis” of features rather than identifying causal psychological laws. Philosophy itself is redefined not as a body of doctrine or a search for new facts, but as a methodological skill for resolving linguistic muddles through the systematic arrangement of recognized trivialities. – AI-generated abstract.
