The paper puts forward that the basic principle of Wittgenstein’s Tractatus (4.0312) transforms the supreme principle of all synthetic judgments a priori in Kant’s Critique of Pure Reason (A158/B197) from a level of reason to the level of language. Both philosophers, Kant and Wittgenstein, put forward a transcendental principle and both hold a formal identity true, Kant an identity between the form of experience and the form of the object of experience, Wittgenstein an identity between the form of a sentence (...) and the form of a fact.

Wittgenstein, possibly the most influential philosopher of the twentieth century, is often labelled a Neopositivist, a New-Kantian, even a Sceptic. Questions on Wittgenstein , first published in 1988, presents a selection of nine essays investigating a matter of vital philosophical importance: Wittgenstein’s relationship to his Austrian predecessors and peers. The intention throughout is to determine the precise contours of Wittgenstein’s own thought by situating it within its formative context. Although it remains of particular interest to Anglo-Saxon philosophers, special familiarity with (...) Austrian philosophy is required to appreciate the subtle and profound influence which this cultural and philosophical setting had on Wittgenstein’s intellectual development. Professor Haller has spent his career exploring these themes, and is one of the foremost authorities on both Wittgenstein and contemporary Austrian philosophy. Questions on Wittgenstein thus offers a unique insight into the twentieth-century tradition of Austrian philosophy, and its importance for Wittgenstein’s thought. (shrink)
