Failure To Refer
In the philosophy of language, failure to refer, also reference failure, referential failure or failure of reference, is the concept that names can fail to name a real object. According to Bertrand Russell's theory of truth, there is only one actual world, and a statement's truth value depends on whether the statement obtains in the actual world. Continuing the tradition of Gottlob Frege, Bertrand Russell posited that a name picks out, or refers to, a real object in the world (Russell's correspondence theory of truth). The name ''Genghis Khan'' thus picks out the 12th and 13th century Mongol leader we know by that name. Any sentence in which we attach a predicate to the name ''Genghis Khan'' is true if the predicate obtains in the actual world. Any sentence in which the predicate does not obtain for Genghis Khan is false. The Wikipedia statement “''Genghis Khan founded the largest contiguous empire in world history''” is thus true, and the statement “''Genghis Khan was one of ...

Philosophy Of Language
In analytic philosophy, philosophy of language investigates the nature of language and the relations between language, language users, and the world. Investigations may include inquiry into the nature of 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 positivists, and Willard Van Orman Quine. In continental philosophy, language is not studied as a separate discipline. Rather, it is an inextricable part of many other areas of thought, such as phenomenology, structural semiotics, language of mathematics, hermeneutics, existentialism, deconstruction and critical theory. History Ancient philosophy In the West, inquiry into language stretches back to the 5th century BC with Socrates, Plato, Aristotl ...

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 ...

Truth Value
In logic and mathematics, a truth value, sometimes called a logical value, is a value indicating the relation of a proposition to truth, which in classical logic has only two possible values (''true'' or '' false''). Computing In some programming languages, any expression can be evaluated in a context that expects a Boolean data type. Typically (though this varies by programming language) expressions like the number zero, the empty string, empty lists, and null evaluate to false, and strings with content (like "abc"), other numbers, and objects evaluate to true. Sometimes these classes of expressions are called "truthy" and "falsy" / "false". Classical logic In classical logic, with its intended semantics, the truth values are ''true'' (denoted by ''1'' or the verum ⊤), and '' untrue'' or '' false'' (denoted by ''0'' or the falsum ⊥); that is, classical logic is a two-valued logic. This set of two values is also called the Boolean domain. Corresponding semantics of l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gottlob Frege
Friedrich Ludwig Gottlob Frege (; ; 8 November 1848 – 26 July 1925) was a German philosopher, logician, and mathematician. He was a mathematics professor at the University of Jena, and is understood by many to be the father of analytic philosophy, concentrating on the philosophy of language, logic, and mathematics. Though he was largely ignored during his lifetime, Giuseppe Peano (1858–1932), Bertrand Russell (1872–1970), and, to some extent, Ludwig Wittgenstein (1889–1951) introduced his work to later generations of philosophers. Frege is widely considered to be the greatest logician since Aristotle, and one of the most profound philosophers of mathematics ever. His contributions include the development of modern logic in the ''Begriffsschrift'' and work in the foundations of mathematics. His book the ''Foundations of Arithmetic'' is the seminal text of the logicist project, and is cited by Michael Dummett as where to pinpoint the linguistic turn. His philosophical ...

Correspondence Theory Of Truth
In metaphysics and philosophy of language, the correspondence theory of truth states that the truth or falsity of a statement is determined only by how it relates to the world and whether it accurately describes (i.e., corresponds with) that world.Hanna and Harrison (2004), ch. 1, p. 21, quotation: "The assessment of truth and falsity is made possible by the existence of semantically mediated correlations between the members of some class of linguistic entities possessing assertoric force (in some versions of the Correspondence Theory propositions, in others sentences, or bodies of sentences), and the members of some class of extralinguistic entities: “states of affairs,” or “facts,” or bodies of truth-conditions, or of assertion-warranting circumstances." Correspondence theories claim that true beliefs and true statements correspond to the actual state of affairs. This type of theory attempts to posit a relationship between thoughts or statements on one hand, and things ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mongol
The Mongols ( mn, Монголчууд, , , ; ; russian: Монголы) are an East Asian ethnic group native to Mongolia, Inner Mongolia in China and the Buryatia Republic of the Russian Federation. The Mongols are the principal member of the large family of Mongolic peoples. The Oirats in Western Mongolia as well as the Buryats and Kalmyks of Russia are classified either as distinct ethno-linguistic groups or subgroups of Mongols. The Mongols are bound together by a common heritage and ethnic identity. Their indigenous dialects are collectively known as the Mongolian language. The ancestors of the modern-day Mongols are referred to as Proto-Mongols. Definition Broadly defined, the term includes the Mongols proper (also known as the Khalkha Mongols), Buryats, Oirats, the Kalmyk people and the Southern Mongols. The latter comprises the Abaga Mongols, Abaganar, Aohans, Baarins, Chahars, Eastern Dorbets, Gorlos Mongols, Jalaids, Jaruud, Kharchins, Khishigten, Khorch ...

Oscar Wilde
Oscar Fingal O'Flahertie Wills Wilde (16 October 185430 November 1900) was an Irish poet and playwright. After writing in different forms throughout the 1880s, he became one of the most popular playwrights in London in the early 1890s. He is best remembered for his epigrams and plays, his novel ''The Picture of Dorian Gray'', and the circumstances of his criminal conviction for gross indecency for consensual homosexual acts in "one of the first celebrity trials", imprisonment, and early death from meningitis at age 46. Wilde's parents were Anglo-Irish intellectuals in Dublin. A young Wilde learned to speak fluent French and German. At university, Wilde read Literae Humaniores#Greats, Greats; he demonstrated himself to be an exceptional Classics, classicist, first at Trinity College Dublin, then at Magdalen College, Oxford, Oxford. He became associated with the emerging philosophy of aestheticism, led by two of his tutors, Walter Pater and John Ruskin. After university, Wilde m ...

Long John Silver
Long John Silver is a fictional character and the main antagonist in the novel ''Treasure Island'' (1883) by Robert Louis Stevenson. The most colourful and complex character in the book, he continues to appear in popular culture. His missing leg and parrot, in particular, have greatly contributed to the image of the pirate in popular culture. Profile Long John Silver is a cunning and opportunistic pirate who was quartermaster under the notorious Captain Flint. Stevenson's portrayal of Silver has greatly influenced the modern iconography of the pirate. Long John Silver has a parrot, named Captain Flint in honor—or mockery—of his former captain,Stevenson (1883), "The Voyage" h. 10 pp. 80f. who generally perches on Silver's shoulder, and is known to chatter pirate or seafaring phrases like "Pieces of Eight", and "Stand by to go about." Silver uses the parrot as another means of gaining Jim's trust, by telling the boy all manner of exciting stories about the parrot's buc ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Samuel Taylor Coleridge
Samuel Taylor Coleridge (; 21 October 177225 July 1834) was an English poet, literary critic, philosopher, and theologian who, with his friend William Wordsworth, was a founder of the Romantic Movement in England and a member of the Lake Poets. He also shared volumes and collaborated with Charles Lamb, Robert Southey, and Charles Lloyd. He wrote the poems ''The Rime of the Ancient Mariner'' and ''Kubla Khan'', as well as the major prose work ''Biographia Literaria''. His critical work, especially on William Shakespeare, was highly influential, and he helped introduce German idealist philosophy to English-speaking cultures. Coleridge coined many familiar words and phrases, including "suspension of disbelief". He had a major influence on Ralph Waldo Emerson and American transcendentalism. Throughout his adult life, Coleridge had crippling bouts of anxiety and depression; it has been speculated that he had bipolar disorder, which had not been defined during his lifetime.Jamis ...
