تعريف logical positivism في الإنجليزية الإنجليزية القاموس.
a general philosophical position, also called logical empiricism, developed by members of the Vienna Circle on the basis of traditional empirical thought and the development of modern logic Logical positivism confined knowledge to science and used verificationism to reject metaphysics not as false but as meaningless The importance of science led leading logical positivists to study scientific method and to explore the logic of confirmation theory
A philosophy asserting the primacy of observation in assessing the truth of statements of fact and holding that metaphysical and subjective arguments not based on observable data are meaningless. Also called logical empiricism. Early school of analytic philosophy, inspired by David Hume, the mathematical logic of Bertrand Russell and Alfred North Whitehead, and Ludwig Wittgenstein's Tractatus (1921). The school, formally instituted at the University of Vienna in a seminar of Moritz Schlick (1882-1936) in 1922, continued there as the Vienna Circle until 1938. It proposed several revolutionary theses: (1) All meaningful discourse consists either of (a) the formal sentences of logic and mathematics or (b) the factual propositions of the special sciences; (2) Any assertion that claims to be factual has meaning only if it is possible to say how it might be verified; (3) Metaphysical assertions, including the pronouncements of religion, belong to neither of the two classes of (1) and are therefore meaningless. Some logical positivists, notably A.J. Ayer, held that assertions in ethics (e.g., "It is wrong to steal") do not function logically as statements of fact but only as expressions of the speaker's feelings of approval or disapproval toward some action. See also Rudolf Carnap; emotivism; verifiability principle
The name adopted by the Vienna Circle (including Rudolf Carnap and Alfred Ayer) for their philosophical position, most famous for introducing the verification principle as a criterion for meaning of synthetic propositions, and for dismissing metaphysics as meaningless
the philosophical school of thought associated with Carnap and Ayer that claims only analytic and synthetic statements are meaningful and that because metaphysical and ethical statements are neither, the latter are meaningless
The philosophy of the Vienna Circle, according to which any purported statement of fact, if not a verbal truism, is meaningless unless certain conceivable observations would serve to conform or deny it
system of philosophy based on experience and empirical knowledge of natural phenomena, in which metaphysics and theology are regarded as inadequate and imperfect systems of knowledge See also Wittgenstein, Ludwig Josef Johann, Russell, Bertrand, and Analytic and Linguistic Philosophy
Twentieth-century philosophical movement that is known for its determination to police assertive statements in order to reject as meaningless non-empirical statements that can not be verified This means that logical positivism rejects all statements of metaphysics, theology, ethics and aesthetics as nonsense The philosophy is represented by the work of Bertrand Russell, (early but not late) Ludwig Wittgensein, A J Ayer and the members of the Vienna Circle
