Nothingness
Nothing, no-thing, or no thing is the complete absence of ''anything'', as the opposite of ''something'' and an antithesis of everything. The concept of nothing has been a matter of philosophical debate since at least the 5th century BCE. Early Greek philosophers argued that it was impossible for ''nothing'' to "exist". The atomists allowed ''nothing'' but only in the spaces between the invisibly small atoms. For them, all space was filled with atoms. Aristotle took the view that there exists matter and there exists space, a receptacle into which matter objects can be placed. This became the paradigm for classical scientists of the modern age like Isaac Newton. Nevertheless, some philosophers, like René Descartes, continued to argue against the existence of empty space until the scientific discovery of a physical vacuum. Existentialists like Jean-Paul Sartre and Martin Heidegger (as interpreted by Sartre) have associated ''nothing'' with consciousness. Some writers have made ...

Existence
Existence is the state of having being or reality in contrast to nonexistence and nonbeing. Existence is often contrasted with essence: the essence of an entity is its essential features or qualities, which can be understood even if one does not know whether the entity exists. Ontology is the philosophical discipline studying the nature and types of existence. Singular existence is the existence of individual entities while general existence refers to the existence of concepts or universals. Entities present in space and time have Abstract and concrete, concrete existence in contrast to abstract entities, like numbers and sets. Other distinctions are between Subjunctive possibility, possible, Contingency (philosophy), contingent, and Metaphysical necessity, necessary existence and between Matter, physical and Mind, mental existence. The common view is that an entity either exists or not with nothing in between, but some philosophers say that there are degrees of existence, me ...

Monist
Monism attributes oneness or singleness () to a concept, such as to existence. Various kinds of monism can be distinguished: * Priority monism states that all existing things go back to a source that is distinct from them; e.g., in Neoplatonism everything is derived from The One. In this view only the One is ontologically fundamental or prior to everything else. * Existence monism posits that, strictly speaking, there exists only a single thing, the universe, which can only be artificially and arbitrarily divided into many things. * Substance monism asserts that a variety of existing things can be explained in terms of a single reality or substance. Substance monism posits that only one kind of substance exists, although many things may be made up of this substance, e.g., matter or mind. * Dual-aspect monism is the view that the mental and the physical are two aspects of, or perspectives on, the same substance. * Neutral monism believes the fundamental nature of reality to be ...

Martin Heidegger
Martin Heidegger (; 26 September 1889 – 26 May 1976) was a German philosopher known for contributions to Phenomenology (philosophy), phenomenology, hermeneutics, and existentialism. His work covers a range of topics including metaphysics, art, and language. In April 1933, Heidegger was elected as Rector (academia), rector at the University of Freiburg and has been widely criticized for his membership and support for the Nazi Party during his tenure. After World War II he was dismissed from Freiburg and banned from teaching after denazification hearings at Freiburg. There has been controversy about the relationship between Martin Heidegger and Nazism, his philosophy and Nazism. In Heidegger's first major text, ''Being and Time'' (1927), ''Dasein'' is introduced as a term for the type of being that humans possess. Heidegger believed that Dasein already has a "pre-ontological" and concrete understanding that shapes how it lives, which he analyzed in terms of the unitary structur ...

Jean-Paul Sartre
Jean-Paul Charles Aymard Sartre (, ; ; 21 June 1905 – 15 April 1980) was a French philosopher, playwright, novelist, screenwriter, political activist, biographer, and literary criticism, literary critic, considered a leading figure in 20th-century French philosophy and Marxism. Sartre was one of the key figures in the philosophy of existentialism (and Phenomenology (philosophy), phenomenology). His work has influenced sociology, critical theory, post-colonial theory, and literary studies. He was awarded the 1964 Nobel Prize in Literature despite attempting to refuse it, saying that he always declined official honors and that "a writer should not allow himself to be turned into an institution." Sartre held an open relationship with prominent feminist and fellow existentialist philosopher Simone de Beauvoir. Together, Sartre and de Beauvoir challenged the culture, cultural and society, social assumptions and expectations of their upbringings, which they considered bourgeois, ...

Opposite
In lexical semantics, opposites are words lying in an inherently incompatible binary relationship. For example, something that is ''even'' entails that it is not ''odd''. It is referred to as a 'binary' relationship because there are two members in a set of opposites. The relationship between opposites is known as opposition. A member of a pair of opposites can generally be determined by the question: "What is the opposite of ''X''" The term antonym (and the related antonymy) is commonly taken to be synonymous with opposite, but antonym also has other more restricted meanings. Graded (or gradable) antonyms are word pairs whose meanings are opposite and which lie on a continuous spectrum (''hot'', ''cold''). Complementary antonyms are word pairs whose meanings are opposite but whose meanings do not lie on a continuous spectrum (''push'', ''pull''). Relational antonyms are word pairs where opposite makes sense only in the context of the relationship between the two meanings (''teache ...

Aether Theories
In the history of physics, aether theories (or ether theories) proposed the existence of a medium, a space-filling substance or field as a transmission medium for the propagation of electromagnetic or gravitational forces. Since the development of special relativity, theories using a substantial aether fell out of use in modern physics, and are now replaced by more abstract models. This early modern aether has little in common with the aether of classical elements from which the name was borrowed. The assorted theories embody the various conceptions of this medium and substance. Historical models Luminiferous aether Isaac Newton suggests the existence of an aether in the Third Book of ''Opticks'' (1st ed. 1704; 2nd ed. 1718): "Doth not this aethereal medium in passing out of water, glass, crystal, and other compact and dense bodies in empty spaces, grow denser and denser by degrees, and by that means refract the rays of light not in a point, but by bending them gradually in ...

Giacomo Casanova
Giacomo Girolamo Casanova (; ; 2 April 1725 – 4 June 1798) was an Italian adventurer who was born in the Republic of Venice and travelled extensively throughout Europe. He is chiefly remembered for his autobiography, written in French and published posthumously as ("The Story of My Life"). That work has come to be regarded as a unique and provocative source of information on the customs and norms of European social life in the 18th century. Born to a family of actors, Casanova studied law at the University of Padua and received minor orders in the Catholic Church with a view towards pursuing a career as a canon lawyer. However, he had no enthusiasm for the law or vocation for the church, and he soon abandoned those plans and launched instead upon an itinerant life as a gambler, violinist, confidence trickster, and man of letters. Throughout his life, Casanova obtained money and other advantages from various aristocratic patrons by pretending to possess alchemical, cab ...

Absurdity
Absurdity is the state or condition of being unreasonable, meaningless, or so unsound as to be irrational. "Absurd" is the adjective used to describe absurdity, e.g., "Tyler and the boys laughed at the absurd situation." It derives from the Latin ''absurdum'' meaning "out of tune". The Latin ''surdus'' means "deaf", implying stupidity. Absurdity is contrasted with being realistic or reasonable In general usage, absurdity may be synonymous with nonsense, meaninglessness, fancifulness, foolishness, bizarreness, wildness. In specialized usage, absurdity is related to extremes in bad reasoning or pointlessness in reasoning; ridiculousness is related to extremes of incongruous juxtaposition, laughter, and ridicule; and nonsense is related to a lack of meaningfulness. Absurdism is a concept in philosophy related to the notion of absurdity. Philosophy Ancient Greece The Classical Greek philosopher Plato often used "absurdity" to describe very poor reasoning, or the conclusion fro ...

Parmenides
Parmenides of Elea (; ; fl. late sixth or early fifth century BC) was a Pre-Socratic philosophy, pre-Socratic ancient Greece, Greek philosopher from Velia, Elea in Magna Graecia (Southern Italy). Parmenides was born in the Greek colony of Velia, Elea to a wealthy and illustrious family. The exact date of his birth is not known with certainty; on the one hand, according to the Doxography, doxographer Diogenes Laërtius, Parmenides flourished in the period immediately preceding 500 BC, which would place his year of birth around 540 BC; on the other hand, in the dialogue ''Parmenides (dialogue), Parmenides'' Plato portrays him as visiting Athens at the age of 65, when Socrates was a young man, , which, if true, suggests a potential year of birth of . Parmenides is thought to have been in his prime (or "floruit") around 475 BC. The single known work by Parmenides is a philosophical poem in dactylic hexameter verse whose original title is unknown but which is often referred to as '' ...

Socrates
Socrates (; ; – 399 BC) was a Ancient Greek philosophy, Greek philosopher from Classical Athens, Athens who is credited as the founder of Western philosophy and as among the first moral philosophers of the Ethics, ethical tradition of thought. An enigmatic figure, Socrates authored no texts and is known mainly through the posthumous accounts of classical writers, particularly his students Plato and Xenophon. These accounts are written as dialogues, in which Socrates and his interlocutors examine a subject in the style of question and answer; they gave rise to the Socratic dialogue literary genre. Contradictory accounts of Socrates make a reconstruction of his philosophy nearly impossible, a situation known as the Socratic problem. Socrates was a polarizing figure in Athenian society. In 399 BC, he was accused of Asebeia, impiety and corrupting the youth. After Trial of Socrates, a trial that lasted a day, he was sentenced to death. He spent his last day in prison ...

Quantum Field Theory
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines Field theory (physics), field theory and the principle of relativity with ideas behind quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles. The current standard model of particle physics is based on QFT. History Quantum field theory emerged from the work of generations of theoretical physicists spanning much of the 20th century. Its development began in the 1920s with the description of interactions between light and electrons, culminating in the first quantum field theory—quantum electrodynamics. A major theoretical obstacle soon followed with the appearance and persistence of various infinities in perturbative calculations, a problem only resolved in the 1950s with the invention of the renormalization procedure. A second major barrier came with QFT's apparent inabili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plato
Plato ( ; Greek language, Greek: , ; born BC, died 348/347 BC) was an ancient Greek philosopher of the Classical Greece, Classical period who is considered a foundational thinker in Western philosophy and an innovator of the written dialogue and dialectic forms. He influenced all the major areas of theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in History of Athens, Athens where Plato taught the doctrines that would later become known as Platonism. Plato's most famous contribution is the theory of forms, theory of forms (or ideas), which aims to solve what is now known as the problem of universals. He was influenced by the pre-Socratic thinkers Pythagoras, Heraclitus, and Parmenides, although much of what is known about them is derived from Plato himself. Along with his teacher Socrates, and his student Aristotle, Plato is a central figure in the history of Western philosophy. Plato's complete ...
