Descriptivist Theory Of Names
In the philosophy of language, the descriptivist theory of proper names (also descriptivist theory of reference) is the view that the meaning or semantic content of a proper name is identical to the descriptions associated with it by speakers, while their referents are determined to be the objects that satisfy these descriptions. Bertrand Russell and Gottlob Frege have both been associated with the descriptivist theory, which has been called the '' mediated reference theory'' or ''Frege–Russell view''. In the 1970s, this theory came under attack from causal theorists such as Saul Kripke, Hilary Putnam and others. However, it has seen something of a revival in recent years, especially under the form of what are called two-dimensional semantic theories. This latter trend is exemplified by the theories of David Chalmers, among others. The descriptive theory and its merits A simple descriptivist theory of names can be thought of as follows: for every proper name ''p'', there is so ...

Philosophy Of Language
Philosophy of language refers to the philosophical study of the nature of language. It investigates the relationship between language, language users, and the world. Investigations may include inquiry into the nature of Meaning (philosophy), meaning, intentionality, reference, the constitution of sentences, concepts, learning, and thought. Gottlob Frege and Bertrand Russell were pivotal figures in analytic philosophy's "linguistic turn". These writers were followed by Ludwig Wittgenstein (''Tractatus Logico-Philosophicus''), the Vienna Circle, Logical positivism, logical positivists, and Willard Van Orman Quine. History Ancient philosophy In the West, inquiry into language stretches back to the 5th century BC with philosophers such as Socrates, Plato, Aristotle, and the Stoics. Linguistic speculation predated systematic descriptions of grammar which emerged in India and in Greece. In the dialogue ''Cratylus (dialogue), Cratylus'', Plato considered the question of whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sense And Reference
In the philosophy of language, the distinction between sense and reference was an idea of the German philosopher and mathematician Gottlob Frege in 1892 (in his paper "On Sense and Reference"; German: "Über Sinn und Bedeutung"), reflecting the two ways he believed a singular term may have meaning. The reference (or "referent"; ''Bedeutung'') of a ''proper name'' is the object it means or indicates (''bedeuten''), whereas its sense (''Sinn'') is what the name expresses. The reference of a ''sentence'' is its truth value, whereas its sense is the thought that it expresses."On Sense and Reference" Über Sinn und Bedeutung" '' Zeitschrift für Philosophie und philosophische Kritik'', vol. 100 (1892), pp. 25–50, esp. p. 31. Frege justified the distinction in a number of ways. #Sense is something possessed by a name, whether or not it has a reference. For example, the name "Odysseus" is intelligible, and therefore has a sense, even though there is no individual object (its refer ...

Jerrold Katz
Jerrold Jacob Katz (14 July 19327 February 2002) was an American philosopher and linguist. Biography After receiving a PhD in philosophy from Princeton University in 1960, Katz became a research associate in linguistics at the Massachusetts Institute of Technology in 1961. He was appointed assistant professor of philosophy there in 1963, and became professor in 1969. From 1975 until his death, he was Distinguished Professor of Philosophy and Linguistics at the City University of New York. Within linguistics, Katz is best known for his theory of semantics in generative grammar, which he refers to as the autonomous theory of sense (ATS). Katz was a staunch defender of rationalism (although not in a Cartesian/ Fregean sense) and the metaphysical import of "essences". He argued extensively against the dominance of empiricism In philosophy, empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experie ...

Kent Bach
Kent Bach (born 1943) is an American philosopher and Professor of Philosophy at San Francisco State University. His primary areas of research include the philosophy of language, linguistics and epistemology. He is the author of three books: ''Exit-existentialism: A philosophy of self-awareness'', ''Linguistic Communication and Speech Acts'', and ''Thought and Reference'' published by Wadsworth, the MIT Press, and Oxford University Press, respectively. Philosophy of language Bach's writings in the philosophy of language have tended to focus on the problems and puzzles that arise from so-called propositional attitude attributions, in particular belief attributions. Such attributions (or ''reports'') take the form ''A believes that p'' where ''A'' is the subject to whom a belief is attributed and ''p'' represents the sentence, proposition (or, more vaguely still, ''content'') that is supposed to be believed by ''A''. In ''A Puzzle About Belief Reports'' and ''Do Belief Reports R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kurt Gödel
Kurt Friedrich Gödel ( ; ; April 28, 1906 – January 14, 1978) was a logician, mathematician, and philosopher. Considered along with Aristotle and Gottlob Frege to be one of the most significant logicians in history, Gödel profoundly influenced scientific and philosophical thinking in the 20th century (at a time when Bertrand Russell,For instance, in their "Principia Mathematica' (''Stanford Encyclopedia of Philosophy'' edition). Alfred North Whitehead, and David Hilbert were using logic and set theory to investigate the foundations of mathematics), building on earlier work by Frege, Richard Dedekind, and Georg Cantor. Gödel's discoveries in the foundations of mathematics led to the proof of his completeness theorem in 1929 as part of his dissertation to earn a doctorate at the University of Vienna, and the publication of Gödel's incompleteness theorems two years later, in 1931. The incompleteness theorems address limitations of formal axiomatic systems. In parti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Possible World
A possible world is a complete and consistent way the world is or could have been. Possible worlds are widely used as a formal device in logic, philosophy, and linguistics in order to provide a semantics for intensional and modal logic. Their metaphysical status has been a subject of controversy in philosophy, with modal realists such as David Lewis arguing that they are literally existing alternate realities, and others such as Robert Stalnaker arguing that they are not. Logic Possible worlds are one of the foundational concepts in modal and intensional logics. Formulas in these logics are used to represent statements about what ''might'' be true, what ''should'' be true, what one ''believes'' to be true and so forth. To give these statements a formal interpretation, logicians use structures containing possible worlds. For instance, in the relational semantics for classical propositional modal logic, the formula \Diamond P (read as "possibly P") is actually true if and ...

Logical Truth
Logical truth is one of the most fundamental concepts in logic. Broadly speaking, a logical truth is a statement which is true regardless of the truth or falsity of its constituent propositions. In other words, a logical truth is a statement which is not only true, but one which is true under all interpretations of its logical components (other than its logical constants). Thus, logical truths such as "if p, then p" can be considered tautologies. Logical truths are thought to be the simplest case of statements which are analytically true (or in other words, true by definition). All of philosophical logic can be thought of as providing accounts of the nature of logical truth, as well as logical consequence. Logical truths are generally considered to be ''necessarily true''. This is to say that they are such that no situation could arise in which they could fail to be true. The view that logical statements are necessarily true is sometimes treated as equivalent to saying that lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Orwell
Eric Arthur Blair (25 June 1903 – 21 January 1950) was an English novelist, poet, essayist, journalist, and critic who wrote under the pen name of George Orwell. His work is characterised by lucid prose, social criticism, opposition to all totalitarianism (both authoritarian communism and fascism), and support of democratic socialism. Orwell is best known for his allegorical novella ''Animal Farm'' (1945) and the Utopian and dystopian fiction, dystopian novel ''Nineteen Eighty-Four'' (1949), although his works also encompass literary criticism, poetry, fiction and polemical journalism. 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 (Spanish Civil War), Republican faction of the Spanish Civil War (1936–1939), are as critically respected as George Orwell bibliograph ...

Animal Farm
''Animal Farm'' (originally ''Animal Farm: A Fairy Story'') is a satirical allegorical novella, in the form of a beast fable, by George Orwell, first published in England on 17 August 1945. It tells the story of a group of anthropomorphic farm animals who rebel against their human farmer, hoping to create a society where the animals can be equal, free, and happy and away from human interventions. However, by the end of the novella, the rebellion is betrayed, and under the dictatorship of a pig named Napoleon (Animal Farm), Napoleon, the farm ends up in a far worse state than it was before. According to Orwell, ''Animal Farm'' reflects events leading up to the Russian Revolution of 1917 and then on into the History of the Soviet Union (1927–1953), Stalinist era of the Soviet Union, a period when Russia lived under the Marxism–Leninism, Marxist–Leninist ideology of Joseph Stalin. Orwell, a democratic socialist, was a critic of Stalin and hostile to Moscow-directed Stalinis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nineteen Eighty-Four
''Nineteen Eighty-Four'' (also published as ''1984'') is a dystopian novel and cautionary tale by the English writer George Orwell. It was published on 8 June 1949 by Secker & Warburg as Orwell's ninth and final completed book. Thematically, it centres on the consequences of totalitarianism, mass surveillance and repressive regimentation of people and behaviours within society. Orwell, a democratic socialist and an anti-Stalinist, modelled Britain under authoritarian socialism in the novel on the Soviet Union in the era of Stalinism and the practices of censorship and propaganda in Nazi Germany. More broadly, the book 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. The current year is uncertain, but believed to be 1984. 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 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logical Consequence
Logical consequence (also entailment or logical implication) is a fundamental concept in logic which describes the relationship between statement (logic), statements that hold true when one statement logically ''follows from'' one or more statements. A Validity (logic), valid logical argument is one in which the Consequent, conclusion is entailed by the premises, because the conclusion is the consequence of the premises. The philosophical analysis of logical consequence involves the questions: In what sense does a conclusion follow from its premises? and What does it mean for a conclusion to be a consequence of premises?Beall, JC and Restall, Greg, Logical Consequence' The Stanford Encyclopedia of Philosophy (Fall 2009 Edition), Edward N.

A Priori And A Posteriori
('from the earlier') and ('from the later') are Latin phrases used in philosophy to distinguish types of knowledge, justification, or argument by their reliance on experience. knowledge is independent from any experience. Examples include mathematics,Some associationist philosophers have contended that mathematics comes from experience and is not a form of any ''a priori'' knowledge () tautologies and deduction from pure reason. Galen Strawson has stated that an argument is one in which "you can see that it is true just lying on your couch. You don't have to get up off your couch and go outside and examine the way things are in the physical world. You don't have to do any science." () knowledge depends on empirical evidence. Examples include most fields of science and aspects of personal knowledge. The terms originate from the analytic methods found in '' Organon'', a collection of works by Aristotle.
