98-616: A tautological character, that is its statements are analytical statements , thus very different from Kantian synthetic statements. The only two kinds of statements accepted by the Vienna Circle are synthetic statements a posteriori (i.e., scientific statements) and analytic statements a priori (i.e., logical and mathematical statements). However, the persistence of metaphysics is connected not only with logical mistakes but also with "social and economical struggles". Metaphysics and theology are allied to traditional social forms, while

147-520: A general philosophical school but steadily moved toward logic. The Lwów–Warsaw school of logic lay at the origin of Polish logic and was closely associated with or was part of the Warsaw School of Mathematics . According to Jan Woleński , a decisive factor in the school's development was the view that the future of the Polish school of mathematics depended on the research connected with the new branches of

196-488: A variety of disciplines, from mathematics through logic to psychology , the Lwów–Warsaw School is widely considered to have been a philosophical movement. It has produced some of the leading logicians of the twentieth century such as Jan Łukasiewicz , Stanisław Leśniewski , and Alfred Tarski , among others. Its members did not only contribute to the techniques of logic but also to various domains that belong to

245-411: Is "the notion that thinking can either lead to knowledge out of its own resources without using any empirical material, or at least arrive at new contents by an inference from given states of affair". Synthetic knowledge a priori is rejected by the Vienna Circle. Mathematics, which at a first sight seems an example of necessarily valid synthetic knowledge derived from pure reason alone, has instead

294-475: Is in many cases unsettled. The partition into "members" and "those sympathetic to the Vienna Circle" produced in the manifesto from 1929 is representative only of a specific moment in the development of the Circle. Depending on the criteria used (regular attendance, philosophical affinities etc.) there are different possible distributions in "inner circle" and "periphery". In the following list (in alphabetical order),

343-431: Is the method of clarification of philosophical problems; it makes an extensive use of symbolic logic and distinguishes the Vienna Circle empiricism from earlier versions. The task of philosophy lies in the clarification—through the method of logical analysis—of problems and assertions. Logical analysis shows that there are two different kinds of statements; one kind includes statements reducible to simpler statements about

392-517: The International Encyclopedia of Unified Science (edited by Neurath, Carnap and Charles W. Morris , 1938–1970). From the beginning of the 1930s first signs of disintegration appeared for political and racist reasons: Herbert Feigl left Austria in 1930. Carnap was appointed to a chair at Prague University in 1931 and left for Chicago in 1935. 1934 marks an important break: Hahn died after surgery, Neurath fled to Holland because of

441-404: The International Encyclopedia of Unified Science : The Vienna Circle cannot be assigned one single philosophy. First, there existed a plurality of philosophical positions within the Circle, and second, members often changed their views fundamentally in the course of time and in reaction to discussions in the Circle. It thus seems more convenient to speak of "the philosophies (in the plural) of

490-600: The annexation of Austria to Nazi Germany in 1938 meant the definite end of the activities of the Vienna Circle in Austria. With the emigration went along the internationalization of logical empiricism . Many former members of the Vienna Circle and the Berlin Circle emigrated to the English-speaking world where they had an immense influence on the development of philosophy of science . The unity of science movement for

539-609: The completeness of first-order logic and the incompleteness of formal arithmetic . Another very interesting congress was the one held in Copenhagen (1936), which was dedicated to quantum physics and causality . Between 1928 and 1937, the Vienna Circle published ten books in a collection named Schriften zur wissenschaftlichen Weltauffassung ( Monographs on the Scientific World-Conception ), edited by Schlick and Frank. Karl Raimund Popper 's book Logik der Forschung

588-596: The philosophy of language . Polish philosophy and the Lwów–Warsaw school were considerably influenced by Franz Brentano and his pupils Kazimierz Twardowski, Anton Marty , Alexius Meinong , and Edmund Husserl . Twardowski founded the philosophical school when he became the chair of the Lviv University. Principal topics of interest to the Lwów–Warsaw school included formal ontology , mereology , and universal or categorial grammar . The Lwów-Warsaw School began as

637-999: The "inner circle" is defined using the criterion of regular attendance. The "periphery" comprises occasional visitors, foreign visitors and leading intellectual figures who stood in regular contact with the Circle (such as Wittgenstein and Popper). Inner Circle: Gustav Bergmann , Rudolf Carnap , Herbert Feigl , Philipp Frank , Kurt Gödel , Hans Hahn , Olga Hahn-Neurath , Béla Juhos , Felix Kaufmann , Victor Kraft , Karl Menger , Richard von Mises , Otto Neurath , Rose Rand , Josef Schächter , Moritz Schlick , Friedrich Waismann , Edgar Zilsel .

Morris , Arne Naess , Karl Raimund Popper , Willard Van Orman Quine , Frank P. Ramsey , Hans Reichenbach , Kurt Reidemeister , Alfred Tarski , Olga Taussky-Todd , Ludwig Wittgenstein . The spread of logical positivism in

686-475: The British academia with the work of the Vienna Circle with his book Language, Truth, and Logic (1936). Karl Popper was also important for the reception and critique of their work, even though he never participated in the meetings of the Vienna Circle. The Vienna Circle was very active in advertising their new philosophical ideas. Several congresses on epistemology and philosophy of science were organized, with

735-497: The French philosophy of science of Henri Poincaré and Pierre Duhem , and also to connect them with the investigations in logic of such authors as Couturat , Schröder , Hilbert, etc. A number of further authors were discussed in the meetings such as Brentano , Meinong , Helmholtz , Hertz , Husserl , Freud , Russell , Whitehead , Lenin and Frege . Presumably the meetings stopped in 1912, when Frank went to Prague , to hold

784-551: The United States occurred throughout the 1920s and 1930s. In 1929 and in 1932, Schlick was a visiting professor at Stanford , while Feigl, who immigrated to the United States in 1930, became lecturer (1931) and professor (1933) at the University of Iowa . The definite diffusion of logical positivism in the United States was due to Carl Hempel, Hans Reichenbach, Rudolf Carnap, Philipp Frank, and Herbert Feigl, who emigrated and taught in

833-486: The United States. Another link to the United States is Willard Van Orman Quine , who traveled in 1932 and 1933 as a Sheldon Traveling Fellow to Vienna , Prague , and Warsaw . Moreover, American semiotician and philosopher Charles W. Morris helped many German and Austrian philosophers emigrate to the United States, including Rudolf Carnap, in 1936. In the United Kingdom it was Alfred Jules Ayer who acquainted

882-551: The Vienna Circle and the Berlin Society took over the journal Annalen der Philosophie and made it the main journal of logical empiricism under the title Erkenntnis , edited by Carnap and Reichenbach. In addition, the Vienna Circle published a number of book series: Schriften zur wissenschaftlichen Weltauffassung ( Monographs on the Scientific World-Conception , ed. by Schlick und Frank, 1928–1937), Einheitswissenschaft ( Unified Science , edited by Neurath, 1933–1939), and later

931-439: The Vienna Circle in Austria. The history and development of the Vienna Circle shows various stages: The pre-history of the Vienna Circle began with meetings on the philosophy of science and epistemology from 1908 on, promoted by Philipp Frank , Hans Hahn and Otto Neurath . Hans Hahn , the oldest of the three (1879–1934), was a mathematician. He received his degree in mathematics in 1902. Afterwards he studied under

980-424: The Vienna Circle". However, some central topics and debates can be identified. This states the scientific world-conception of the Vienna Circle, which is characterized "essentially by two features. First it is empiricist and positivist: there is knowledge only from experience. Second, the scientific world-conception is marked by the application of a certain method, namely logical analysis ." Logical analysis

1029-583: The Vienna Circle. In 1929 the Vienna Circle made its first public appearance under this name – invented by Neurath – with the publication of its manifesto Wissenschaftliche Weltauffassung. Der Wiener Kreis ( The Scientific Conception of the World. The Vienna Circle also known as Viewing the World Scientifically: The Vienna Circle ) The pamphlet is dedicated to Schlick, and its preface was signed by Hahn, Neurath and Carnap. The manifesto

1078-548: The World was intensely discussed in the Circle. Also Wittgenstein's Tractatus logico-philosophicus was read out loud and discussed. From 1927 on personal meetings were arranged between Wittgenstein and Schlick, Waismann, Carnap and Feigl. In 1928 the Verein Ernst Mach ( Ernst Mach Society ) was founded, with Schlick as its chairman. The aim of the society was the spreading of a "scientific world conception" through public lectures that were in large part held by members of

1127-409: The aim of making philosophy scientific with the help of modern logic . Main topics were foundational debates in the natural and social sciences, logic and mathematics; the modernization of empiricism by modern logic; the search for an empiricist criterion of meaning; the critique of metaphysics and the unification of the sciences in the unity of science . The Vienna Circle appeared in public with

1176-467: The chair of theoretical physics left vacant by Albert Einstein . Hahn left Vienna during World War I and returned in 1921. The formation of the Vienna Circle began with Hahn returning to Vienna in 1921. Together with the mathematician Kurt Reidemeister he organized seminars on Ludwig Wittgenstein 's Tractatus logico-philosophicus and on Whitehead and Russell's Principia Mathematica . With

1225-536: The construction of an International Encyclopedia of Unified Science , promoted mainly by Neurath, Carnap, and Morris, is symptomatic of the internationalization of logical empiricism, organizing numerous international conferences and the publication of the International Encyclopedia of Unified Science . Apart from the central figures of the Schlick Circle the question of membership in the Vienna Circle

1274-741: The direction of Ludwig Boltzmann in Vienna and David Hilbert , Felix Klein and Hermann Minkowski in Göttingen . In 1905 he received the Habilitation in mathematics. He taught at Innsbruck (1905–1906) and Vienna (from 1909). Otto Neurath (1882–1945) studied mathematics , political economy , and history in Vienna and Berlin. From 1907 to 1914 he taught in Vienna at the Neue Wiener Handelsakademie (Viennese Commercial Academy). Neurath married Olga, Hahn's sister, in 1911. Philipp Frank ,

1323-413: The empirically given; the other kind includes statements which cannot be reduced to statements about experience and thus they are devoid of meaning. Metaphysical statements belong to this second kind and therefore they are meaningless. Hence many philosophical problems are rejected as pseudo-problems which arise from logical mistakes, while others are re-interpreted as empirical statements and thus become

1372-405: The field such as set theory and topology , which are closely related to mathematical logic. The "philosophical branch" followed Twardowski's tradition and produced notable thinkers such as Bronisław Bandrowski , who addressed the problem of induction and Tadeusz Kotarbiński , who is known for developing Reism . In the 1930s Alfred Tarski initiated contacts with the Vienna Circle . Tarski,

1421-442: The group of people who "faces modern times, rejects these views and takes its stand on the ground of empirical sciences". Thus the struggle between metaphysics and scientific world-conception is not only a struggle between different kinds of philosophies, but it is also—and perhaps primarily—a struggle between different political, social, and economical attitudes. Of course, as the manifesto itself acknowledged, "not every adherent of

1470-516: The help of the Berlin Circle . There were some preparatory congresses: Prague (1929), Königsberg (1930), Prague (1934) and then the first congress on scientific philosophy held in Paris (1935), followed by congresses in Copenhagen (1936), Paris (1937), Cambridge , UK (1938), Cambridge, Massachusetts . (1939). The Königsberg congress (1930) was very important, for Kurt Gödel announced that he had proven

1519-466: The mathematicians around Hahn. In 1924 Schlick's students Friedrich Waismann and Herbert Feigl suggested to their teacher a sort of regular "evening circle". From winter term 1924 on regular meetings were held at the Institute of Mathematics in Vienna's Boltzmanngasse 5 on personal invitation by Schlick. These discussions can be seen as the beginning of the Vienna Circle. The group that met from 1924 on

1568-520: The most prominent member of the Lwów–Warsaw School, has been ranked as one of the four greatest logicians of all time, along with Aristotle , Gottlob Frege , and Kurt Gödel . The school's work was interrupted by the outbreak of World War II . Despite this, its members went on to fundamentally influence modern science, notably mathematics and logic , in the post-war period. Tarski's description of semantic truth, for instance, has revolutionized logic and philosophy. In contemporary Polish learning,

1617-512: The natural sciences and metaphysics, the public phase of the Vienna Circle was explicitly political. Neurath and Hahn were both socialists and believed the rejection of magic was a necessary component for liberation of the working classes. The manifesto linked Karl Marx and Friedrich Nietzsche to their political and anti-metaphysical views, indicating a blur between what are now considered two separate schools of contemporary philosophy – analytic philosophy and continental philosophy . In 1930

1666-583: The philosopher Jan Woleński considers himself close to the School's heritage. In 2013 Woleński was awarded by the Foundation for Polish Science for his comprehensive analysis of the work of the Lwów–Warsaw school and for placing its achievements within the international discourse of contemporary analytic philosophy .

1813-455: The scientific world-conception will be a fighter". Many historians of the Vienna Circle see in the latter sentence an implicit reference to a contrast between the so-called 'left wing' of the Vienna Circle, mainly represented by Neurath and Carnap, and Moritz Schlick. The aim of the left wing was to facilitate the penetration of the scientific world-conception in "the forms of personal and public life, in education , upbringing, architecture , and

1862-458: The subject of scientific inquiries. One source of the logical mistakes that are at the origins of metaphysics is the ambiguity of natural language . "Ordinary language for instance uses the same part of speech , the substantive, for things ('apple') as well as for qualities ('hardness'), relations ('friendship'), and processes ('sleep'); therefore it misleads one into a thing-like conception of functional concepts ". Another source of mistakes

[...] To this group belonged the mathematician H. Hahn, the political economist Otto Neurath, and the author of this book [i.e. Frank], at the time an instructor in theoretical physics in Vienna. [...] We tried to supplement Mach's ideas by those of

2254-687: Was presented at the Tagung für Erkenntnislehre der exakten Wissenschaften ( Conference on the Epistemology of the Exact Sciences ) in autumn 1929, organized by the Vienna Circle together with the Berlin Circle . This conference was the first international appearance of logical empiricism and the first of a number of conferences: Königsberg ( 1930 ), Prague (1934), Paris (1935), Copenhague (1936), Cambridge , UK (1938), Cambridge, Mass. (1939), and Chicago (1941). While primarily known for its views on
