logical positivismDoctrine that the only meaningful propositions are those that can be verified empirically. Metaphysics, religion, and aesthetics are therefore meaningless. However, the doctrine itself cannot be verified empirically and so is self-refuting. Logical positivism was characteristic of the Vienna Circle in the 1920s and 1930s, and was influenced by Friedrich Frege, Bertrand Russell, and Ludwig Wittgenstein. Logical positivists have expended much effort in trying to resolve its inherent contradiction. How to thank TFD for its existence?

The knowledge representations resting upon the epistemological foundations of logical positivism in its operationalist and representational approaches to meaning are further distanced from natural language than those resting upon an instrumental approach to meaning. Going on to question this early formalist approach, a move that evoked Ludwig Wittgenstein's reevaluation in Philosophical Investigations of the logical positivism of Tractatus, he created a subjective, associative language of architecture using what he called masques. The Principia project did suggest the need for precise logical formulation of the truth conditions of sentences--something that became a consuming interest of logical positivism and some species of "analytic" philosophy. |
