Leon Chwistek
Leon Chwistek (Kraków, Austria-Hungary, 13 June 1884 – Barvikha near Moscow, Russia, 20 August 1944) was a Polish logician, philosopher, mathematician, avant-garde painter, theoretician of modern art and literary critic. Career and philosophy In 1919 he was one of the founders of the Polish Mathematical Society. From 1922, he lectured in mathematics for natural scientists at the Jagiellonian University, where he obtained his habilitation in 1928 in mathematical logic. Starting in 1929, Chwistek was a Professor of Logic at the University of Lwów in a position for which Alfred Tarski had also applied. His interests in the 1930s were in a general system of philosophy of science, which was published in a book translated in English 1948 as ''The Limits of Science''. In the 1920s–30s, many European philosophers attempted to reform traditional philosophy by means of mathematical logic. Leon Chwistek did not believe that such reform could succeed. He thought that reality could n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Tarski
Alfred Tarski (; ; born Alfred Teitelbaum;School of Mathematics and Statistics, University of St Andrews ''School of Mathematics and Statistics, University of St Andrews''. January 14, 1901 – October 26, 1983) was a Polish-American logician and mathematician. A prolific author best known for his work on model theory, metamathematics, and algebraic logic, he also contributed to abstract algebra, topology, geometry, measure theory, mathematical logic, set theory, type theory, and analytic philosophy. Educated in Poland at the University of Warsaw, and a member of the Lwów–Warsaw school, Lwów–Warsaw school of logic and the Warsaw school of mathematics, he immigrated to the United States in 1939 where he became a naturalized citizen in 1945. Tarski taught and carried out research in mathematics at the University of California, Berkeley, from 1942 until his death in 1983.#FefA, Feferman A.

Primitivism
In the arts of the Western world, Primitivism is a mode of aesthetic idealization that means to recreate the experience of ''the primitive'' time, place, and person, either by emulation or by re-creation. In Western philosophy, Primitivism proposes that the people of a primitive society possess a morality and an ethics that are superior to the urban value system of civilized people. In European art, the aesthetics of primitivism included techniques, motifs, and styles copied from the arts of Asian, African, and Australasian peoples perceived as primitive in relation to the urban civilization of Western Europe. In that light, the painter Paul Gauguin's inclusion of Tahitian imagery to his oil paintings was a characteristic borrowing of technique, motif, and style that was important for the development of Modern art (1860s–1970s) in the late 19th century. As a genre of Western art, Primitivism reproduced and perpetuated racist stereotypes, such as the " noble savage", wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axiomatic Method
In mathematics and logic, an axiomatic system is a set of formal statements (i.e. axioms) used to logically derive other statements such as lemmas or theorems. A proof within an axiom system is a sequence of deductive steps that establishes a new statement as a consequence of the axioms. An axiom system is called complete with respect to a property if every formula with the property can be derived using the axioms. The more general term theory is at times used to refer to an axiomatic system and all its derived theorems. In its pure form, an axiom system is effectively a syntactic construct and does not by itself refer to (or depend on) a formal structure, although axioms are often defined for that purpose. The more modern field of model theory refers to mathematical structures. The relationship between an axiom systems and the models that correspond to it is often a major issue of interest. Properties Four typical properties of an axiom system are consistency, rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Of Polish Patriots
Union of Polish Patriots (''Society of Polish Patriots'', , ZPP, ) was a political body created by Polish communists in the Soviet Union in 1943. The ZPP, unofficially controlled and directed by Joseph Stalin, became one of the founding structures of the Soviet-controlled communist government that after World War II took power in Poland. The ZPP was a mass organization with about 100,000 members (Polish citizens in the Soviet Union, mostly war refugees and Soviet deportees left after the departure of Anders' Army). It was dominated by former members of the Communist Party of Poland, in particular people from the Central Bureau Communists of Poland, which was established after the ZPP and also operated in the Soviet Union. The ZPP included activists of many political orientations. During World War II, there were about 1,500 declared Polish communists in the Soviet Union.Andrzej Werblan, Szkice i polemiki ketches and polemics p. 168, published in 1970 by Książka i Wiedza, Wa ...

Writers' Union Of Ukraine
The National Writers' Union of Ukraine () (''НСПУ'') is a voluntary social-creative association of professional writers, poets, prose writers, playwrights, critics, and translators. History The National Writers' Union of Ukraine was founded in 1934 as the Ukrainian SSR Union of Writers, a part of the Union of Soviet Writers, which was established in the same year. In post-communist time, the Writers' Union of Ukraine declared its independence from any Soviet structures (1991). In 1997 the Union split, losing some of its members who created a new organization, the Association of Ukrainian Writers. In 2020, the Union blacklisted publications from countries that politically opposed the "territorial integrity of Ukraine." The list included Russia, Belarus, China, and Armenia. After the 2022 Russian invasion of Ukraine, the NSPU called for the Mikhail Bulgakov Museum to be closed. Mikhail Bulgakov, who the museum honors, was accused of anti-Ukrainian and imperialist attit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Formal Logic
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the study of deductively valid inferences or logical truths. It examines how conclusions follow from premises based on the structure of arguments alone, independent of their topic and content. Informal logic is associated with informal fallacies, critical thinking, and argumentation theory. Informal logic examines arguments expressed in natural language whereas formal logic uses formal language. When used as a countable noun, the term "a logic" refers to a specific logical formal system that articulates a proof system. Logic plays a central role in many fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises that leads to a conclusion. An example is the argument from the premises "it's Sunday" and "if it's Sunday then I don't have to work" leading to the conclusion "I don't have to wor ...
