The purpose of this paper is threefold. First, I visit the Fogelin–Geach-dispute, criticizeMiller''s interpretation of the Geachian notationN(x:N(fx)) and conclude that Fogelin''s argumentagainst the expressive completeness of the Tractariansystem of logic is unacceptable and that the adoptionof the Geachian notation N(x:fx) would not violate TLP5.32. Second, I prove that a system of quantificationtheory with finite domains and with N as the solefundamental operation is expressively complete. Lastly, I argue that the Tractarian system is apredicate-eliminated many-sorted theory (withoutidentity) with finite domains (...) and with N as the solefundamental operation, and thus is expressivelycomplete.

The Tractatus contains twodifferent proofs of the Grundgedanke, or thenonreferentiality of logical constants. In thispaper, I explicate the first proof in TLP 5.4s andreconstruct the less explicitly stated second proof. My explication of the first proof shows it to beelegant but based on an invalid inference. In myreconstruction of the second proof, the main argumentis that the sign of a logical constant does not denotebecause it possesses the punctuation-mark-nature. Andit possesses the punctuation-mark-nature because,given the analyticity thesis in TLP 5, one (...) canestablish for everyday language an adequate symbolismwith N as the sole fundamental operation such that itssign is a bar indicating merely the order and scope ofits application.

This revised edition of Sir Anthony Kenny’s classic work on Wittgenstein contains a new introduction which covers developments in Wittgenstein scholarship since the book was first published. Widely praised for providing a lucid and historically informed account of Wittgenstein’s core philosophical concerns. Demonstrates the continuity between Wittgenstein’s early and later writings. Provides a persuasive argument for the unity of Wittgenstein’s thought. Kenny also assesses Wittgenstein’s influence in the latter part of the twentieth century.

This is the first of David Pears's acclaimed two‐volume work on the development of Wittgenstein's philosophy, covering the pre‐1929 writings. Part I of the first volume consists in a brief but eloquent overview of Wittgenstein's philosophy as a whole; Part II critically examines the earlier system, delineating and evaluating the central ideas (logical atomism, picture theory of meaning, and solipsism) with intellectual rigour and clarity. Pears succeeds in both offering an original realist interpretation of Wittgenstein's earlier thought, one that has (...) found many followers, and in demarcating a structural framework that makes the internal organization of Wittgenstein's philosophy as a whole more accessible.
