Apophantic
Apophantic ( el, ἀποφαντικός, "declaratory", from ἀποφαίνειν ''apophainein'', "to show, to make known") is a term Aristotle coined to mean a specific type of declaratory statement that can determine the truth or falsity of a logical proposition or phenomenon. It was adopted by Edmund Husserl and Martin Heidegger as part of phenomenology. Herbert Marcuse defines it as "the logic of judgment". In Aristotle's usage, the Greek term ἀποφαντικὸς λόγος (apophantic speech) describes a statement that, by examining a proposition in itself, can determine what is true about a statement by establishing whether or not the predicate of a sentence may logically be attributed to its subject. For example, logical propositions may be divided into ones that are semantically determinate, as in the sentence "All penguins are birds," and those that are semantically indeterminate, as in the sentence "All bachelors are unhappy." In the first proposition, the subject ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of philosophy within the Lyceum and the wider Aristotelian tradition. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, meteorology, geology, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logical Proposition
In logic and linguistics, a proposition is the meaning of a declarative sentence. In philosophy, " meaning" is understood to be a non-linguistic entity which is shared by all sentences with the same meaning. Equivalently, a proposition is the non-linguistic bearer of truth or falsity which makes any sentence that expresses it either true or false. While the term "proposition" may sometimes be used in everyday language to refer to a linguistic statement which can be either true or false, the technical philosophical term, which differs from the mathematical usage, refers exclusively to the non-linguistic meaning behind the statement. The term is often used very broadly and can also refer to various related concepts, both in the history of philosophy and in contemporary analytic philosophy. It can generally be used to refer to some or all of the following: The primary bearers of truth values (such as "true" and "false"); the objects of belief and other propositional attitudes (i.e ...

Martin Heidegger
Martin Heidegger (; ; 26 September 188926 May 1976) was a German philosopher who is best known for contributions to phenomenology, hermeneutics, and existentialism. He is among the most important and influential philosophers of the 20th century. He has been widely criticized for supporting the Nazi Party after his election as rector at the University of Freiburg in 1933, and there has been controversy about the relationship between his philosophy and Nazism. In Heidegger's fundamental text ''Being and Time'' (1927), "Dasein" is introduced as a term for the type of being that humans possess. Dasein has been translated as "being there". Heidegger believes that Dasein already has a "pre-ontological" and non-abstract understanding that shapes how it lives. This mode of being he terms " being-in-the-world". Dasein and "being-in-the-world" are unitary concepts at odds with rationalist philosophy and its "subject/object" view since at least René Descartes. Heidegger explicitly disag ...

Phenomenology (philosophy)
Phenomenology (from Greek φαινόμενον, ''phainómenon'' "that which appears" and λόγος, ''lógos'' "study") is the philosophical study of the structures of experience and consciousness. As a philosophical movement it was founded in the early years of the 20th century by Edmund Husserl and was later expanded upon by a circle of his followers at the universities of Göttingen and Munich in Germany. It then spread to France, the United States, and elsewhere, often in contexts far removed from Husserl's early work. Phenomenology is not a unified movement; rather, the works of different authors share a 'family resemblance' but with many significant differences. Gabriella Farina states:A unique and final definition of phenomenology is dangerous and perhaps even paradoxical as it lacks a thematic focus. In fact, it is not a doctrine, nor a philosophical school, but rather a style of thought, a method, an open and ever-renewed experience having different results, and this m ...

Herbert Marcuse
Herbert Marcuse (; ; July 19, 1898 – July 29, 1979) was a German-American philosopher, social critic, and political theorist, associated with the Frankfurt School of critical theory. Born in Berlin, Marcuse studied at the Humboldt University of Berlin and then at Freiburg, where he received his PhD. He was a prominent figure in the Frankfurt-based Institute for Social Research – what later became known as the Frankfurt School. He was married to Sophie Wertheim (1924–1951), Inge Neumann (1955–1973), and Erica Sherover (1976–1979). In his written works, he criticized capitalism, modern technology, Soviet Communism and popular culture, arguing that they represent new forms of social control. Between 1943 and 1950, Marcuse worked in US government service for the Office of Strategic Services (predecessor of the Central Intelligence Agency) where he criticized the ideology of the Communist Party of the Soviet Union in the book '' Soviet Marxism: A Critical Analysis'' (195 ...

Subject (grammar)
The subject in a simple English sentence such as ''John runs'', ''John is a teacher'', or ''John drives a car'', is the person or thing about whom the statement is made, in this case ''John''. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees (''John is'' but ''John and Mary are''). If there is no verb, as in ''John what an idiot!'', or if the verb has a different subject, as in ''John I can't stand him!'', then 'John' is not considered to be the grammatical subject, but can be described as the ''topic'' of the sentence. While these definitions apply to simple English sentences, defining the subject is more difficult in more complex sentences and in languages other than English. For example, in the sentence ''It is difficult to learn French'', the subject seems to be the word ''it'', and yet arguably the real subject (the thing that is difficult) is ''to learn French''. A sentence such as ''It was J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Penguins
Penguins ( order Sphenisciformes , family Spheniscidae ) are a group of aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the little blue penguin (''Eudyptula minor''), also known as the fairy penguin, which stands around tall and weighs . Today, larger penguins generally inhabit colder regions, and smaller penguins in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Bachelors
A bachelor is a man who is not and has never been married.Bachelors are, in Pitt & al.'s phrasing, "men who live independently, outside of their parents' home and other institutional settings, who are neither married nor cohabitating". (). Etymology A bachelor is first attested as the 12th-century ''bacheler'': a knight bachelor, a knight too young or poor to gather vassals under his own banner. The Old French ' presumably derives from Provençal ' and Italian ', but the ultimate source of the word is uncertain.''Oxford English Dictionary'', 1st ed.bachelor, ''n.'' Oxford University Press (Oxford), 1885. The proposed Medieval Latin * ("vassal", "field hand") is only attested late enough that it may have derived from the vernacular languages, rather than from the southern French and northern Spanish Latin . Alternatively, it has been derived from Latin ' ("a stick"), in reference to the wooden sticks used by knights in training. History From the 14th century, the term "bachelor ...

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 log ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contingency (philosophy)
In philosophy and logic, contingency is the status of propositions that are neither true under every possible valuation (i.e. tautologies) nor false under every possible valuation (i.e. contradictions). A contingent proposition is neither necessarily true nor necessarily false. Overview Propositions that are contingent may be so because they contain logical connectives which, along with the truth value of any of its atomic parts, determine the truth value of the proposition. This is to say that the truth value of the proposition is ''contingent'' upon the truth values of the sentences which comprise it. Contingent propositions depend on the facts, whereas analytic propositions are true without regard to any facts about which they speak. Along with contingent propositions, there are at least three other classes of propositions, some of which overlap: * '' Tautological'' propositions, which ''must'' be true, no matter what the circumstances are or could be (example: "It is the cas ...
