Tractatus Logico-Philosophicus"Philosophy is not a theory," asserted Austro-British philosopher Ludwig Wittgenstein (1889–1951), "but an activity." In this 1921 opus, his only philosophical work published during his lifetime, Wittgenstein defined the object of philosophy as the logical clarification of thoughts and proposed the solution to most philosophic problems by means of a critical method of linguistic analysis. In proclaiming philosophy as a matter of logic rather than of metaphysics, Wittgenstein created a sensation among intellectual circles that influenced the development of logical positivism and changed the direction of 20th-century thought. |
