logical positivism,

also known as logical or scientific empiricism, modern school of philosophy that attempted to introduce the methodology and precision of mathematics and the natural sciences into the field of philosophy. The movement, which began in the early 20th cent., was the fountainhead of the modern trend that considers philosophy an analytical, rather than a speculative, inquiry. It began in the group called the Vienna Circle, which formed around Moritz Schlick when he occupied (1920s) a chair of philosophy at the Univ. of Vienna. Among its members were the philosophers Friedrich Waismann, Otto Neurath, Rudolf Carnap, Herbert Feigl, and Victor Kraft, and the mathematicians Hans Hahn, Carl Menger, and Kurt Gödel. The movement soon had a widespread following in Europe and the United States. Among those philosophers whose work was influenced by the Vienna Circle are A. J. AyerAyer, Sir Alfred Jules

. The Vienna Circle in general subscribed to Wittgenstein's dictum in Tractatus Logico-Philosophicus that the object of philosophy was the logical clarification of thought; philosophy was not a theory but an activity. The logical positivists made a concerted effort to clarify the language of science by showing that the content of scientific theories could be reduced to truths of logic and mathematics coupled with propositions referring to sense experience. They held that metaphysical speculation was nonsensical, propositions of logic and mathematics tautological, and moral or value statements merely emotive. They championed the highly influential verification principle, from which it follows that a proposition has meaning only if some sense experience would suffice to determine its truth. The Vienna Circle disintegrated after the Nazis took control of Austria in the late 1930s. The influence of the movement, as a movement, ended c.1940. However, the concepts of the movement, particularly in its emphasis on the function of philosophy as the analysis of language, has been carried on throughout the West.

logical positivism

the philosophical doctrine of a group of philosophers -including R. Carnap (1891-1970) and O. Neurath (1882-1945) – known collectively as the Vienna Circle. See POSITIVISM.

Logical Positivism

 

a current of neopositivism that emerged in the 1920’s from the Vienna circle.

The logical positivists attempted to combine empiricism, based on the verifiability principle, with a method of logical analysis of scientific knowledge for the purpose of reducing the latter to an “immediate given,” that is, to an empirically verifiable content of scientific concepts and assertions. In the second half of the 1930’s, after its principal representatives (R. Carnap, H. Feigl, C. Hempel, and P. Frank) moved to the United States, logical positivism became known as logical empiricism.

By the late 1930’s, the logical positivists had rejected a number of the original epistemological dogmas that had been formulated by the Vienna circle and that had proved unsound in attempts to carry through a logical analysis of science. In particular, the logical positivists rejected the principle of the reduction of scientific knowledge to an empirically known datum.

In the 1950’s, logical positivism lost its position as the leading trend in the philosophy of science. In the 1960’s, logical positivism for all intents and purposes ceased to exist as an independent philosophical movement. However, despite criticism of the original viewpoints of the logical positivists, their ideas continue to be influential among many representatives of science.
