Logical Positivism
Logical positivism, later called logical empiricism, and both of which together are also known as neopositivism, is a movement in Western philosophy whose central thesis was the verification principle (also known as the verifiability criterion of meaning). This theory of knowledge asserted that only statements verifiable through direct observation or logical proof are meaningful in terms of conveying truth value, information or factual content. Starting in the late 1920s, groups of philosophers, scientists, and mathematicians formed the Berlin Circle and the Vienna Circle, which, in these two cities, would propound the ideas of logical positivism. Flourishing in several European centres through the 1930s, the movement sought to prevent confusion rooted in unclear language and unverifiable claims by converting philosophy into "scientific philosophy", which, according to the logical positivists, ought to share the bases and structures of empirical sciences' best examples, such as ...

Western Philosophy
Western philosophy encompasses the philosophical thought and work of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with the ancient Greek philosophy of the pre-Socratics. The word ''philosophy'' itself originated from the Ancient Greek (φιλοσοφία), literally, "the love of wisdom" grc, φιλεῖν , "to love" and σοφία '' sophía'', "wisdom"). History Ancient The scope of ancient Western philosophy included the problems of philosophy as they are understood today; but it also included many other disciplines, such as pure mathematics and natural sciences such as physics, astronomy, and biology (Aristotle, for example, wrote on all of these topics). Pre-Socratics The pre-Socratic philosophers were interested in cosmology; the nature and origin of the universe, while rejecting mythical answers to such questions. They were specifically interested in the (the cause or first principle) of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percy Bridgman
Percy Williams Bridgman (April 21, 1882 – August 20, 1961) was an American physicist who received the 1946 Nobel Prize in Physics for his work on the physics of high pressures. He also wrote extensively on the scientific method and on other aspects of the philosophy of science. The Bridgman effect, the Bridgman–Stockbarger technique, and the high-pressure mineral bridgmanite are named after him. Biography Early life Bridgman was born in Cambridge, Massachusetts, and grew up in nearby Auburndale. Bridgman's parents were both born in New England. His father, Raymond Landon Bridgman, was "profoundly religious and idealistic" and worked as a newspaper reporter assigned to state politics. His mother, Mary Ann Maria Williams, was described as "more conventional, sprightly, and competitive". Bridgman attended both elementary and high school in Auburndale, where he excelled at competitions in the classroom, on the playground, and while playing chess. Described as both shy and ...

Symbolic Logic
Mathematical logic is the study of formal logic within mathematics. Major subareas include model theory, proof theory, set theory, and recursion theory. Research in mathematical logic commonly addresses the mathematical properties of formal systems of logic such as their expressive or deductive power. However, it can also include uses of logic to characterize correct mathematical reasoning or to establish foundations of mathematics. Since its inception, mathematical logic has both contributed to and been motivated by the study of foundations of mathematics. This study began in the late 19th century with the development of axiomatic frameworks for geometry, arithmetic, and analysis. In the early 20th century it was shaped by David Hilbert's program to prove the consistency of foundational theories. Results of Kurt Gödel, Gerhard Gentzen, and others provided partial resolution to the program, and clarified the issues involved in proving consistency. Work in set theory show ...

Logicism
In the philosophy of mathematics, logicism is a programme comprising one or more of the theses that — for some coherent meaning of 'logic' — mathematics is an extension of logic, some or all of mathematics is reducible to logic, or some or all of mathematics may be modelled in logic. Bertrand Russell and Alfred North Whitehead championed this programme, initiated by Gottlob Frege and subsequently developed by Richard Dedekind and Giuseppe Peano. Overview Dedekind's path to logicism had a turning point when he was able to construct a model satisfying the axioms characterizing the real numbers using certain sets of rational numbers. This and related ideas convinced him that arithmetic, algebra and analysis were reducible to the natural numbers plus a "logic" of classes. Furthermore by 1872 he had concluded that the naturals themselves were reducible to sets and mappings. It is likely that other logicists, most importantly Frege, were also guided by the new theories of the real ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bertrand Russell
Bertrand Arthur William Russell, 3rd Earl Russell, (18 May 1872 – 2 February 1970) was a British mathematician, philosopher, logician, and public intellectual. He had a considerable influence on mathematics, logic, set theory, linguistics, artificial intelligence, cognitive science, computer science and various areas of analytic philosophy, especially philosophy of mathematics, philosophy of language, epistemology, and metaphysics.Stanford Encyclopedia of Philosophy"Bertrand Russell" 1 May 2003. He was one of the early 20th century's most prominent logicians, and a founder of analytic philosophy, along with his predecessor Gottlob Frege, his friend and colleague G. E. Moore and his student and protégé Ludwig Wittgenstein. Russell with Moore led the British "revolt against idealism". Together with his former teacher A. N. Whitehead, Russell wrote ''Principia Mathematica'', a milestone in the development of classical logic, and a major attempt to reduce the whole ...

Observational Term
Ramsey sentences are formal logical reconstructions of theoretical propositions attempting to draw a line between science and metaphysics. A Ramsey sentence aims at rendering propositions containing non-observable theoretical terms (terms employed by a theoretical language) clear by substituting them with observational terms (terms employed by an observation language, also called empirical language). Ramsey sentences were introduced by the logical empiricist philosopher Rudolf Carnap. However, they should not be confused with Carnap sentences, which are neutral on whether there exists anything to which the term applies. Distinction between scientific (real) questions and metaphysical (pseudo-)questions For Carnap, questions such as “Are electrons real?” and “Can you prove electrons are real?” were not legitimate questions, nor did they contain any great philosophical or metaphysical truths. Rather, they were meaningless "pseudo-questions without cognitive content,” asked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metaphor
A metaphor is a figure of speech that, for rhetorical effect, directly refers to one thing by mentioning another. It may provide (or obscure) clarity or identify hidden similarities between two different ideas. Metaphors are often compared with other types of figurative language, such as antithesis, hyperbole, metonymy, and simile. One of the most commonly cited examples of a metaphor in English literature comes from the "All the world's a stage" monologue from '' As You Like It'': All the world's a stage, And all the men and women merely players; They have their exits and their entrances And one man in his time plays many parts, His Acts being seven ages. At first, the infant... :—William Shakespeare, '' As You Like It'', 2/7 This quotation expresses a metaphor because the world is not literally a stage, and most humans are not literally actors and actresses playing roles. By asserting that the world is a stage, Shakespeare uses points of comparison between the world an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newspeak
Newspeak is the fictional language of Oceania, a totalitarian superstate that is the setting of the 1949 dystopian novel ''Nineteen Eighty-Four'', by George Orwell. In the novel, the Party created Newspeak to meet the ideological requirements of Ingsoc (English Socialism) in Oceania. Newspeak is a controlled language of simplified grammar and restricted vocabulary designed to limit the individual's ability to think and articulate "subversive" concepts such as personal identity, self-expression, and free will. Such concepts are criminalized as thoughtcrime since they contradict the prevailing Ingsoc orthodoxy. In "The Principles of Newspeak", the appendix to the novel, Orwell explains that Newspeak follows most of the rules of English grammar, yet is a language characterised by a continually diminishing vocabulary; complete thoughts are reduced to simple terms of simplistic meaning. The political contractions of Newspeak—''Ingsoc'' (English Socialism), ''Minitrue'' (Ministry o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ingsoc
In George Orwell's 1949 dystopian novel ''Nineteen Eighty-Four'', the world is divided into three superstates: Oceania, Eurasia and Eastasia, who are all fighting each other in a perpetual war in a disputed area called the Equatorial Front. All that Oceania's citizens know about the world is whatever the Party wants them to know, so how the world evolved into the three states is unknown; and it is also unknown to the reader whether they actually exist in the novel's reality, or whether they are a storyline invented by the Party to advance social control. The nations appear to have emerged from nuclear warfare and civil dissolution over 20 years between 1945 and 1965, in a post-war world where totalitarianism becomes the predominant form of ideology, through Neo-Bolshevikism, IngSoc, and Obliteration of the Self. Sourcing What is known of the society, politics and economics of Oceania, and its rivals, comes from the in-universe book, ''The Theory and Practice of Oligarchical Co ...

George Orwell
Eric Arthur Blair (25 June 1903 – 21 January 1950), better known by his pen name George Orwell, was an English novelist, essayist, journalist, and critic. His work is characterised by lucid prose, social criticism, opposition to totalitarianism, and support of democratic socialism. Orwell produced literary criticism, poetry, fiction and polemical journalism. He is known for the allegorical novella ''Animal Farm'' (1945) and the dystopian novel ''Nineteen Eighty-Four'' (1949). His non-fiction works, including ''The Road to Wigan Pier'' (1937), documenting his experience of working-class life in the industrial north of England, and ''Homage to Catalonia'' (1938), an account of his experiences soldiering for the Republican faction of the Spanish Civil War (1936–1939), are as critically respected as his essays on politics, literature, language and culture. Blair was born in India, and raised and educated in England. After school he became an Imperial policeman in Burma, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nineteen Eighty-Four
''Nineteen Eighty-Four'' (also stylised as ''1984'') is a dystopian social science fiction novel and cautionary tale written by the English writer George Orwell. It was published on 8 June 1949 by Secker & Warburg as Orwell's ninth and final book completed in his lifetime. Thematically, it centres on the consequences of totalitarianism, mass surveillance and repressive regimentation of people and behaviours within society. Orwell, a democratic socialist, modelled the authoritarian state in the novel on Stalinist Russia and Nazi Germany. More broadly, the novel examines the role of truth and facts within societies and the ways in which they can be manipulated. The story takes place in an imagined future in the year 1984, when much of the world is in perpetual war. Great Britain, now known as Airstrip One, has become a province of the totalitarian superstate Oceania, which is led by Big Brother, a dictatorial leader supported by an intense cult of personality manufactured by ...
