The Philosophy Portal A portal for Wikipedia's philosophy resources • 18,317 articles in English The Thinker, a statue by Auguste Rodin, is often used to represent philosophy. Left to right: Plato, Kant, Nietzsche, Buddha, Confucius, Averroes Philosophy ('love of wisdom' in Ancient Greek) is a systematic study of general and fundamental questions concerning topics like existence, reason, knowledge, value, mind, and language. It is a rational and critical inquiry that reflects on its own methods and assumptions. Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western, Arabic–Persian, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues in relation to right social conduct, government, and self-cultivation. Major branches of philosophy are epistemology, ethics, logic, and metaphysics. Epistemology studies what knowledge is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic is the study of correct reasoning and explores how good arguments can be distinguished from bad ones. Metaphysics examines the most general features of reality, existence, objects, and properties. Other subfields are aesthetics, philosophy of language, philosophy of mind, philosophy of religion, philosophy of science, philosophy of mathematics, philosophy of history, and political philosophy. Within each branch, there are competing schools of philosophy that promote different principles, theories, or methods. Philosophers use a great variety of methods to arrive at philosophical knowledge. They include conceptual analysis, reliance on common sense and intuitions, use of thought experiments, analysis of ordinary language, description of experience, and critical questioning. Philosophy is related to many other fields, including the sciences, mathematics, business, law, and journalism. It provides an interdisciplinary perspective and studies the scope and fundamental concepts of these fields. It also investigates their methods and ethical implications. (Full article...)

Title page from the first English edition of Part I The Age of Reason; Being an Investigation of True and Fabulous Theology is a work by English and American political activist Thomas Paine, arguing for the philosophical position of deism. It follows in the tradition of 18th-century British deism, and challenges institutionalized religion and the legitimacy of the Bible. It was published in three parts in 1794, 1795, and 1807. It was a best-seller in the United States, where it caused a deistic revival. British audiences, fearing increased political radicalism as a result of the French Revolution, received it with more hostility. The Age of Reason presents common deistic arguments; for example, it highlights what Paine saw as corruption of the Christian Church and criticizes its efforts to acquire political power. Paine advocates reason in the place of revelation, leading him to reject miracles and to view the Bible as an ordinary piece of literature, rather than a divinely-inspired text. In The Age of Reason, he promotes natural religion and argues for the existence of a creator god. (Full article...) Portrait by August Köhler, c. 1910, after 1627 original Johannes Kepler (/ˈkɛplər/; German: [joˈhanəs ˈkɛplɐ, -nɛs -] ; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae, influencing among others Isaac Newton, providing one of the foundations for his theory of universal gravitation. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural and modern science. He has been described as the "father of science fiction" for his novel Somnium. Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, being named the father of modern optics, in particular for his Astronomiae pars optica. He also invented an improved version of the refracting telescope, the Keplerian telescope, which became the foundation of the modern refracting telescope, while also improving on the telescope design by Galileo Galilei, who mentioned Kepler's discoveries in his work.

The problem of religious language considers whether it is possible to talk about God meaningfully if the traditional conceptions of God as being incorporeal, infinite, and timeless, are accepted. Because these traditional conceptions of God make it difficult to describe God, religious language has the potential to be meaningless. Theories of religious language either attempt to demonstrate that such language is meaningless, or attempt to show how religious language can still be meaningful. One prevalent position in Islamic philosophy holds that religious language is meaningful and positive, demonstrating the shared attributes of God and His creatures. According to this view, the semantic commonality of attributes between God and humans indicates ontological commonalities between them. This is because factual concepts refer to and are abstracted from realities in the external world. (Full article...) Cantor, c. 1910 Georg Ferdinand Ludwig Philipp Cantor (/ˈkæntɔːr/ KAN-tor; German: [ˈɡeːɔʁk ˈfɛʁdinant ˈluːtvɪç ˈfiːlɪp ˈkantoːɐ̯]; 3 March [O.S. 19 February] 1845 – 6 January 1918) was a mathematician who played a pivotal role in the creation of set theory, which has become a fundamental theory in mathematics. Cantor established the importance of one-to-one correspondence between the members of two sets, defined infinite and well-ordered sets, and proved that the real numbers are more numerous than the natural numbers. Cantor's method of proof of this theorem implies the existence of an infinity of infinities. He defined the cardinal and ordinal numbers and their arithmetic. Cantor's work is of great philosophical interest, a fact he was well aware of. Originally, Cantor's theory of transfinite numbers was regarded as counter-intuitive – even shocking. This caused it to encounter resistance from mathematical contemporaries such as Leopold Kronecker and Henri Poincaré and later from Hermann Weyl and L. E. J. Brouwer, whilst Ludwig Wittgenstein raised philosophical objections; see Controversy over Cantor's theory. Cantor, a devout Lutheran Christian, believed the theory had been communicated to him by God. Some Christian theologians (particularly neo-Scholastics) saw Cantor's work as a challenge to the uniqueness of the absolute infinity in the nature of God – on one occasion equating the theory of transfinite numbers with pantheism – a proposition that Cantor vigorously rejected. Not all theologians were against Cantor's theory; prominent neo-scholastic philosopher Constantin Gutberlet was in favor of it and Cardinal Johann Baptist Franzelin accepted it as a valid theory (after Cantor made some important clarifications). (Full article...) Goldman, c. 1911 Emma Goldman (June 27, 1869 – May 14, 1940) was a Lithuanian-born anarchist revolutionary, political activist, and writer. She played a pivotal role in the development of anarchist political philosophy in North America and Europe in the first half of the 20th century. Born in Kaunas, Lithuania (then within the Russian Empire), to an Orthodox Lithuanian Jewish family, Goldman emigrated to the United States in 1885. Attracted to anarchism after the Chicago Haymarket affair, Goldman became a writer and a renowned lecturer on anarchist philosophy, women's rights, and social issues, attracting crowds of thousands. She and anarchist writer Alexander Berkman, her lover and lifelong friend, planned to assassinate industrialist and financier Henry Clay Frick as an act of propaganda of the deed. Frick survived the attempt on his life in 1892, and Berkman was sentenced to 22 years in prison. Goldman was imprisoned several times in the years that followed, for "inciting to riot" and illegally distributing information about birth control. In 1906, Goldman founded the anarchist journal Mother Earth. (Full article...) Icon of St. Maximus Maximus the Confessor (Greek: Μάξιμος ὁ Ὁμολογητής, romanized: Maximos ho Homologētēs), also spelled Maximos, otherwise known as Maximus the Theologian and Maximus of Constantinople (c. 580 – 13 August 662), was a Christian monk, theologian, and scholar. In his early life, Maximus was a civil servant, and an aide to the Byzantine Emperor Heraclius. He gave up this life in the political sphere to enter the monastic life. Maximus had studied diverse schools of philosophy, and certainly what was common for his time, the Platonic dialogues, the works of Aristotle, and numerous later Platonic commentators on Aristotle and Plato, like Plotinus, Porphyry, Iamblichus, and Proclus. When one of his friends began espousing the Christological position known as Monothelitism, Maximus was drawn into the controversy, in which he supported an interpretation of the Chalcedonian formula on the basis of which it was asserted that Jesus had both a human and a divine will. Maximus is venerated in both the Catholic and Eastern Orthodox Churches. He was eventually persecuted for his Christological positions; following a trial, his tongue and right hand were mutilated. (Full article...) The tree of life as depicted by Ernst Haeckel in The Evolution of Man (1879) illustrates the 19th-century view of evolution as a progressive process leading towards man. Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity—in the ideas of the ancient Greeks, Romans, Chinese, Church Fathers as well as in medieval Islamic science. With the beginnings of modern biological taxonomy in the late 17th century, two opposed ideas influenced Western biological thinking: essentialism, the belief that every species has essential characteristics that are unalterable, a concept which had developed from medieval Aristotelian metaphysics, and that fit well with natural theology; and the development of the new anti-Aristotelian approach to modern science: as the Enlightenment progressed, evolutionary cosmology and the mechanical philosophy spread from the physical sciences to natural history. Naturalists began to focus on the variability of species; the emergence of palaeontology with the concept of extinction further undermined static views of nature. In the early 19th century prior to Darwinism, Jean-Baptiste Lamarck (1744–1829) proposed his theory of the transmutation of species, the first fully formed theory of evolution. In 1858 Charles Darwin and Alfred Russel Wallace published a new evolutionary theory, explained in detail in Darwin's On the Origin of Species (1859). Darwin's theory, originally called descent with modification is known contemporarily as Darwinism or Darwinian theory. Unlike Lamarck, Darwin proposed common descent and a branching tree of life, meaning that two very different species could share a common ancestor. Darwin based his theory on the idea of natural selection: it synthesized a broad range of evidence from animal husbandry, biogeography, geology, morphology, and embryology. Debate over Darwin's work led to the rapid acceptance of the general concept of evolution, but the specific mechanism he proposed, natural selection, was not widely accepted until it was revived by developments in biology that occurred during the 1920s through the 1940s. Before that time most biologists regarded other factors as responsible for evolution. Alternatives to natural selection suggested during "the eclipse of Darwinism" (c. 1880 to 1920) included inheritance of acquired characteristics (neo-Lamarckism), an innate drive for change (orthogenesis), and sudden large mutations (saltationism). Mendelian genetics, a series of 19th-century experiments with pea plant variations rediscovered in 1900, was integrated with natural selection by Ronald Fisher, J. B. S. Haldane, and Sewall Wright during the 1910s to 1930s, and resulted in the founding of the new discipline of population genetics. During the 1930s and 1940s population genetics became integrated with other biological fields, resulting in a widely applicable theory of evolution that encompassed much of biology—the modern synthesis. (Full article...) Political Animals and Animal Politics is a 2014 edited collection published by Palgrave Macmillan and edited by the green political theorists Marcel Wissenburg and David Schlosberg. The work addresses the emergence of academic animal ethics informed by political philosophy as opposed to moral philosophy. It was the first edited collection to be published on the topic, and the first book-length attempt to explore the breadth and boundaries of the literature. As well as a substantial introduction by the editors, it features ten sole-authored chapters split over three parts, respectively concerning institutional change for animals, the relationship between animal ethics and ecologism, and real-world laws made for the benefit of animals. The book's contributors were Wissenburg, Schlosberg, Manuel Arias-Maldonado, Chad Flanders, Christie Smith, Clemens Driessen, Simon Otjes, Kurtis Boyer, Per-Anders Svärd, and Mihnea Tanasescu. The focus of their individual chapters varies, but recurring features include discussions of human exceptionalism, exploration of ways that animal issues are or could be present in political discourse, and reflections on the relationship between theory and practice in politics. In part, Political Animals and Animal Politics arose from a workshop that Wissenburg and Schlosberg organised at the 2012 European Consortium for Political Research Joint Sessions conference, though not all attendees contributed to the volume and not all contributors presented at the workshop. Footage of the workshop appeared in De Haas in de Marathon (The Pacer in the Marathon), a 2012 documentary about the Dutch Party for the Animals. Political Animals and Animal Politics was published as part of the Palgrave Macmillan Animal Ethics Series, edited by Andrew Linzey and Priscilla Cohn. (Full article...) Portrait by Joshua Reynolds, c. 1772 Samuel Johnson (18 September [O.S. 7 September] 1709 – 13 December 1784), often called Dr Johnson, was an English writer who made lasting contributions as a poet, playwright, essayist, moralist, literary critic, sermonist, biographer, editor, and lexicographer. The Oxford Dictionary of National Biography calls him "arguably the most distinguished man of letters in English history". Born in Lichfield, Staffordshire, he attended Pembroke College, Oxford, until lack of funds forced him to leave. After working as a teacher, he moved to London and began writing for The Gentleman's Magazine. Early works include Life of Mr Richard Savage, the poems London and The Vanity of Human Wishes and the play Irene. After nine years' effort, Johnson's A Dictionary of the English Language appeared in 1755, and was acclaimed as "one of the greatest single achievements of scholarship". Later work included essays, an annotated The Plays of William Shakespeare, and the apologue The History of Rasselas, Prince of Abissinia. In 1763 he befriended James Boswell, with whom he travelled to Scotland, as Johnson described in A Journey to the Western Islands of Scotland. Near the end of his life came a massive, influential Lives of the Most Eminent English Poets of the 17th and 18th centuries. (Full article...) Title page, 1798 Maria: or, The Wrongs of Woman is Mary Wollstonecraft's unfinished novelistic sequel to her revolutionary political treatise A Vindication of the Rights of Woman (1792). The Wrongs of Woman was published posthumously in 1798 by her husband, William Godwin, and is often considered her most radical feminist work. Wollstonecraft's philosophical and gothic novel revolves around the story of a woman imprisoned in an insane asylum by her husband. It focuses on the societal rather than the individual "wrongs of woman" and criticizes what Wollstonecraft viewed as the patriarchal institution of marriage in eighteenth-century Britain and the legal system that protected it. However, the heroine's inability to relinquish her romantic fantasies also reveals women's collusion in their oppression through false and damaging sentimentalism. The novel pioneered the celebration of female sexuality and cross-class identification between women. Such themes, coupled with the publication of Godwin's scandalous Memoirs of Wollstonecraft's life, made the novel unpopular at the time it was published. (Full article...) Lenin in 1920 Vladimir Ilyich Ulyanov (22 April 1870 – 21 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist. He served as the first and founding head of government of Soviet Russia from 1917 until his death in 1924, and of the Soviet Union from 1922 to 1924. Under his administration, Russia, and later the Soviet Union, became a one-party socialist state governed by the Communist Party of the Soviet Union (CPSU). Ideologically a Marxist, his developments to the ideology are called Leninism. Born into an upper-middle-class family in Simbirsk, Lenin embraced revolutionary socialist politics following his brother's 1887 execution. Expelled from Kazan Imperial University for participating in protests against the Tsarist government, he devoted the following years to a law degree. He relocated to Saint Petersburg in 1893 where he became a senior Marxist activist. In 1897, he was arrested for sedition and exiled to Shushenskoye in Siberia—where he married Nadezhda Krupskaya—for three years. After his exile, he moved to Western Europe, where he became a prominent theorist in the Marxist Russian Social Democratic Labour Party (RSDLP). In 1903, he took a key role in the RSDLP ideological split, leading the Bolshevik faction against Julius Martov's Mensheviks. Following Russia's failed Revolution of 1905, he initially campaigned for the First World War to be transformed into a Europe-wide proletarian revolution, which, as a Marxist, he believed would cause the overthrow of capitalism and the rise of socialism. After the 1917 February Revolution ousted the Tsar and established a Provisional Government, he returned to Russia and played a leading role in the October Revolution, in which the Bolsheviks overthrew the new government. (Full article...) First edition title page A Vindication of the Rights of Woman: with Strictures on Political and Moral Subjects (1792), written by British philosopher and women's rights advocate Mary Wollstonecraft (1759–1797), is one of the earliest works of feminist philosophy. In it, Wollstonecraft responds to those educational and political theorists of the eighteenth century who did not believe women should receive a rational education. She argues that women ought to have an education commensurate with their position in society, claiming that women are essential to the nation because they educate its children and because they could be "companions" to their husbands, rather than mere wives. Instead of viewing women as ornaments to society or property to be traded in marriage, Wollstonecraft maintains that they are human beings deserving of the same fundamental rights as men. Wollstonecraft was prompted to write the Rights of Woman after reading Charles Maurice de Talleyrand-Périgord's 1791 report to the French National Assembly, which stated that women should only receive domestic education. From her reaction to this specific event, she launched a broad attack against double standards, indicting men for encouraging women to indulge in excessive emotion. Wollstonecraft hurried to complete the work in direct response to ongoing events; she intended to write a more thoughtful second volume but died before completing it. (Full article...) Augustine of Hippo (AD 354–430) as painted by Sandro Botticelli (c. 1445–1510). Augustine is credited with developing the first form of the theodicy now named for him. The Augustinian theodicy, named for the 4th- and 5th-century theologian and philosopher Augustine of Hippo, is a type of Christian theodicy that developed in response to the evidential problem of evil. As such, it attempts to explain the probability of an omnipotent (all-powerful) and omnibenevolent (all-loving) God amid evidence of evil in the world. A number of variations of this kind of theodicy have been proposed throughout history; their similarities were first described by the 20th-century philosopher John Hick, who classified them as "Augustinian". They typically assert that God is perfectly (ideally) good, that he created the world out of nothing, and that evil is the result of humanity's original sin. The entry of evil into the world is generally explained as consequence of original sin and its continued presence due to humans' misuse of free will and concupiscence. God's goodness and benevolence, according to the Augustinian theodicy, remain perfect and without responsibility for evil or suffering. Augustine of Hippo was the first to develop the theodicy. He rejected the idea that evil exists in itself, instead regarding it as a corruption of goodness, caused by humanity's abuse of free will. Augustine believed in the existence of a physical Hell as a punishment for sin, but argued that those who choose to accept the salvation of Jesus Christ will go to Heaven. In the 13th century, Thomas Aquinas – influenced by Augustine – proposed a similar theodicy based on the view that God is goodness and that there can be no evil in him. He believed that the existence of goodness allows evil to exist, through the fault of humans. Augustine also influenced John Calvin, who supported Augustine's view that evil is the result of free will and argued that sin corrupts humans, requiring God's grace to give moral guidance. (Full article...) Title page from the first edition of Locke's Some Thoughts Concerning Education (1693) Some Thoughts Concerning Education is a 1693 treatise on the education of gentlemen written by the English philosopher John Locke. For over a century, it was the most important philosophical work on education in England. It was translated into almost all of the major written European languages during the eighteenth century, and nearly every European writer on education after Locke, including Jean-Jacques Rousseau, acknowledged its influence. In his Essay Concerning Human Understanding (1690), Locke outlined a new theory of mind, contending that the mind is originally a tabula rasa or "blank slate"; that is, it did not contain any innate ideas at birth. Some Thoughts Concerning Education explains how to educate that mind using three distinct methods: the development of a healthy body; the formation of a virtuous character; and the choice of an appropriate academic curriculum. (Full article...) Memorial in Nollendorfplatz, Berlin. Text in triangle: "Struck Dead Hushed Up [dedicated to] The homosexual victims of National Socialism" Text below: "The 'pink triangle' was the sign with which the National Socialists marked homosexuals in the concentration camps in a defamatory way. From January 1933 almost all homosexual locales in and around Nollendorfplatz were closed by the National Socialists or misused by raids to create 'pink lists' (homosexual files)." Before 1933, male homosexual acts were illegal in Germany under Paragraph 175 of the German Criminal Code. The law was not consistently enforced, however, and a thriving gay culture existed in major German cities. After the Nazi takeover in 1933, the first homosexual movement's infrastructure of clubs, organizations, and publications was shut down. After the Röhm purge in 1934, persecuting homosexuals became a priority of the Nazi police state. A 1935 revision of Paragraph 175 made it easier to bring criminal charges for homosexual acts, leading to a large increase in arrests and convictions. Persecution peaked in the years prior to World War II and was extended to areas annexed by Germany, including Austria, the Czech lands, and Alsace–Lorraine. The Nazi regime considered the elimination of all manifestations of homosexuality in Germany one of its goals. Men were often arrested after denunciation, police raids, and through information uncovered during interrogations of other homosexuals. Those arrested were presumed guilty, and subjected to harsh interrogation and torture to elicit a confession. Between 1933 and 1945, an estimated 100,000 men were arrested as homosexuals; around 50,000 of these were sentenced by civilian courts, 6,400 to 7,000 by military courts, and an unknown number by special courts. Most of these men served time in regular prisons, and between 5,000 and 6,000 were imprisoned in concentration camps. The death rate of these prisoners has been estimated at 60 percent, a higher rate than those of other prisoner groups. A smaller number of men were sentenced to death or killed at Nazi euthanasia centres. Nazi Germany's persecution of homosexuals is considered to be the most severe episode in a long history of discrimination and violence targeting sexual minorities. (Full article...)

Selected philosopher of the week Abū-Yūsuf Ya’qūb ibn Ishāq al-Kindī c 801–873CE Abū-Yūsuf Ya’qūb ibn Ishāq al-Kindī, also known by the Latinised version of his name Alkindus to the Western world (Arabic: أبو يوسف يعقوب ابن إسحاق الكندي, was a Muslim Arab scientist, mathematician, physician, and a talented musician. Al-Kindī was born in Kufa, a centre of world learning at the time. Al-Kindi's father was the governor of Kufa, as his grandfather had been before him. Al-Kindi was descended from the Kindah tribe which had migrated from Yemen. This tribe had united a number of tribes and reached a position of prominence in the 5th and 6th centuries, but then lost power from the middle of the 6th century. Al-Kindī's education took place first in Kufa, then in Basra, and finally in Baghdad. Knowledge of his great learning soon spread, and the Caliph al-Ma'mun appointed him to the House of Wisdom in Baghdad, which was a recently established centre for the translation of Greek philosophical and scientific texts. (He was also well known for his beautiful calligraphy, and at one point was employed as a calligrapher by al-Mutawakkil.) ...Schedule Read more... Selected article of the week Zen is a form of Mahayana Buddhism that places great importance on moment-by-moment awareness and 'seeing deeply into the nature of things' by direct experience. Zen emerged as a distinct school in China and spread to Vietnam, Korea, Japan, and, in modern times, the rest of the world. Zen Buddhism is a branch of Mahayana Buddhism, and, as such, its teachings are deeply rooted in those of the Buddha. The Zen schools, like other Buddhist sects, teach the fundamental elements of Buddhist philosophy, including the Four Noble Truths, the Noble Eightfold Path, pratitya samutpada, the five precepts, the five skandhas, and the three dharma seals: non-self, impermanence, and dukkha. Zen philosophy also includes teachings specific to Mahayana Buddhism, including the Mahayanan conception of the paramitas and the ideal of the bodhisattva's universal salvific power... ...Archive/schedule Read more...

Chernyi, c. 1923 Pavel Dmitrievich Turchaninov (Russian: Па́вел Дми́триевич Турчани́нов, IPA: [ˈpavʲɪl ˈdmʲitrʲɪjɪvʲɪtɕ tʊrtɕɪˈnʲinəf]; 1878–1921), commonly known by his pseudonym Lev Chernyi (Russian: Лев Чёрный, IPA: [ˈlʲef ˈtɕɵrnɨj] ) was a Russian individualist anarchist. Having joined the anarchist movement during the Russian Revolution of 1905, during which he developed his individualist theory of "associational anarchism", Chernyi was arrested and exiled to Siberia for his revolutionary activities. After several escape attempts, one of which resulted in mutinous exiles capturing Turukhansk, he managed to flee to Paris, where he stayed until the Russian Revolution of 1917. After returning to Russia, he acted as secretary for the Moscow Federation of Anarchist Groups and organised the Black Guards, the federation's armed wing. As political repression against anarchists intensified after the Bolsheviks took power, Chernyi joined an underground anarchist group, which bombed a Russian Communist Party meeting. In 1921, Chernyi and Fanya Baron were arrested on charges of counterfeiting and were executed by shooting by the Cheka. (Full article...) Vincent van Gogh, 1890. Kröller-Müller Museum. The Good Samaritan (after Delacroix). A conscience is a cognitive process that elicits emotion and rational associations based on an individual's moral philosophy or value system. Conscience stands in contrast to elicited emotion or thought due to associations based on immediate sensory perceptions and reflexive responses, as in sympathetic central nervous system responses. In common terms, conscience is often described as leading to feelings of remorse when a person commits an act that conflicts with their moral values. The extent to which conscience informs moral judgment before an action and whether such moral judgments are or should be based on reason has occasioned debate through much of modern history between theories of basics in ethic of human life in juxtaposition to the theories of romanticism and other reactionary movements after the end of the Middle Ages. Religious views of conscience usually see it as linked to a morality inherent in all humans, to a beneficent universe and/or to divinity. The diverse ritualistic, mythical, doctrinal, legal, institutional and material features of religion may not necessarily cohere with experiential, emotive, spiritual or contemplative considerations about the origin and operation of conscience. Common secular or scientific views regard the capacity for conscience as probably genetically determined, with its subject probably learned or imprinted as part of a culture. (Full article...) Wilde in 1882 Oscar Fingal O'Fflahertie Wills Wilde (16 October 1854 – 30 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 his criminal conviction for gross indecency for homosexual acts. Wilde's parents were Anglo-Irish intellectuals in Dublin. In his youth, Wilde learned to speak fluent French and German. At university, he read Greats; he demonstrated himself to be an exceptional classicist, first at Trinity College Dublin, then at Magdalen College, Oxford. He became associated with the emerging philosophy of aestheticism, led by two of his tutors, Walter Pater and John Ruskin. After university, Wilde moved to London into fashionable cultural and social circles. (Full article...) Marx in 1875 Karl Marx (German: [maʁks]; 5 May 1818 – 14 March 1883) was a German-born philosopher, political theorist, economist, historian, sociologist, journalist, and revolutionary socialist. His best-known works are the 1848 pamphlet The Communist Manifesto (with Friedrich Engels) and his three-volume Das Kapital (1867–1894); the latter employs his critical approach of historical materialism in an analysis of capitalism, in the culmination of his intellectual endeavours. Marx's ideas and their subsequent development, collectively known as Marxism, have had enormous influence on modern intellectual, economic and political history. Born in Trier in the Kingdom of Prussia, Marx studied at the universities of Bonn, Berlin, and Jena, and received a doctorate in philosophy from the latter in 1841. A Young Hegelian, he was influenced by the philosophy of Georg Wilhelm Friedrich Hegel, and both critiqued and developed Hegel's ideas in works such as The German Ideology (written 1846) and the Grundrisse (written 1857–1858). While in Paris in 1844, Marx wrote his Economic and Philosophic Manuscripts and met Engels, who became his closest friend and collaborator. After moving to Brussels in 1845, they were active in the Communist League, and in 1848 wrote The Communist Manifesto, which expresses Marx's ideas and lays out a programme for revolution. Marx was expelled from Belgium and Germany, and in 1849 moved to London, where he wrote The Eighteenth Brumaire of Louis Bonaparte (1852) and Das Kapital. From 1864, Marx was involved in the International Workingmen's Association (First International), in which he fought the influence of anarchists led by Mikhail Bakunin. In his Critique of the Gotha Programme (1875), Marx wrote on revolution, the state and the transition to communism. He died stateless in 1883 and was buried in Highgate Cemetery. (Full article...) Lasker in 1929 Emanuel Lasker (German pronunciation: [eˈmaːnuɛl ˈlaskɐ] ; December 24, 1868 – January 11, 1941) was a German chess player, mathematician, and philosopher. He was the second World Chess Champion, holding the title for 27 years, from 1894 to 1921, the longest reign of any officially recognised World Chess Champion in history. In his prime, Lasker was one of the most dominant champions, and he is still generally regarded as one of the strongest players in history. His contemporaries used to say that Lasker used a "psychological" approach to the game, and even that he sometimes deliberately played inferior moves to confuse opponents. Recent analysis, however, indicates that he was ahead of his time and used a more flexible approach than his contemporaries, which mystified many of them. Lasker knew contemporary analyses of openings well but disagreed with many of them. He published chess magazines and five chess books, but later players and commentators found it difficult to draw lessons from his methods. (Full article...)

This particular volume was a gift from Alexander Hamilton's wife Elizabeth Schuyler Hamilton to her sister Angelica The Federalist Papers is a collection of 85 articles and essays written by Alexander Hamilton, James Madison, and John Jay under the collective pseudonym "Publius" to promote the ratification of the Constitution of the United States. The collection was commonly known as The Federalist until the name The Federalist Papers emerged in the twentieth century. The first seventy-seven of these essays were published serially in the Independent Journal, the New York Packet, and The Daily Advertiser between October 1787 and April 1788. A compilation of these 77 essays and eight others were published in two volumes as The Federalist: A Collection of Essays, Written in Favour of the New Constitution, as Agreed upon by the Federal Convention, September 17, 1787, by publishing firm J. & A. McLean in March and May 1788. The last eight papers (Nos. 78–85) were republished in the New York newspapers between June 14 and August 16, 1788. (Full article...) Winkler County, Texas The Winkler County nurse whistleblower case was a series of legal proceedings in West Texas concerning the retaliation against two nurses who submitted an anonymous state medical board complaint against a physician in 2009. The case attracted national attention for its implications on whistleblowing by nurses. After witnessing what they believed to be unsafe medical care, nurses Anne Mitchell and Vicki Galle submitted an anonymous complaint against Dr. Rolando Arafiles to the Texas Medical Board (TMB). When he learned of the complaint, Arafiles spoke with the sheriff of Winkler County, alleging that the nurses' reports to the medical board constituted harassment. The sheriff investigated and obtained the TMB complaint, which provided enough information that Galle and Mitchell could be identified as the sources of the complaint. Galle and Mitchell were terminated from the hospital and faced criminal charges of misuse of official information. Galle's charges were dropped before trial and Mitchell was acquitted by a jury. In the aftermath of Mitchell's trial, Arafiles, several county officials and a hospital administrator all faced jail time for their roles in the retaliation against the nurses. (Full article...) According to different scholars, the history of anarchism either goes back to ancient and prehistoric ideologies and social structures, or begins in the 19th century as a formal movement. As scholars and anarchist philosophers have held a range of views on what anarchism means, it is difficult to outline its history unambiguously. Some feel anarchism is a distinct, well-defined movement stemming from 19th-century class conflict, while others identify anarchist traits long before the earliest civilisations existed. Prehistoric society existed without formal hierarchies, which some anthropologists have described as similar to anarchism. The first traces of formal anarchist thought can be found in ancient Greece and China, where numerous philosophers questioned the necessity of the state and declared the moral right of the individual to live free from coercion. During the Middle Ages, some religious sects espoused libertarian thought, and the Age of Enlightenment, and the attendant rise of rationalism and science, signalled the birth of the modern anarchist movement.

Durkheim formally established the academic discipline of sociology and is commonly cited as one of the principal architects of modern social science, along with both Karl Marx and Max Weber. Much of Durkheim's work was concerned with how societies can maintain their integrity and coherence in modernity, an era in which traditional social and religious ties are much less universal, and in which new social institutions have come into being. Durkheim's conception of the scientific study of society laid the groundwork for modern sociology, and he used such scientific tools as statistics, surveys, and historical observation in his analysis of suicides in Catholic and Protestant groups.

The Demands of Liberal Education is a 1999 political philosophy book by Meira Levinson that establishes a liberal political theory of children's education that fits the mutual needs of the state and its diverse citizenry. She writes that the intent of a liberal education—an education that follows from a liberal society's values—is to maximize the autonomy of individual children through increasing their capacity for liberty. Levinson argues autonomy as a right to children. The book, published by Oxford University Press, aims to address a lacuna between educational policy and liberal political theory. Levinson advocates for a weak perfectionist state that can promote thick autonomy while accepting citizens who do not agree. She argues for public schools "common" to all citizens and "detached" from individual citizen or community values, and argues for a constitutional mandate to this end. (Full article...) Relief representing ahimsa In Jainism, ahiṃsā (Ahimsā, alternatively spelled 'ahinsā', Sanskrit: अहिंसा IAST: ahinsā, Pāli: avihinsā) is a fundamental principle forming the cornerstone of its ethics and doctrine. The term ahiṃsā means nonviolence, non-injury, and absence of desire to harm any life forms. Veganism, vegetarianism and other nonviolent practices and rituals of Jains flow from the principle of ahimsa. There are five specific transgressions of Ahimsa principle in Jain scriptures – binding of animals, beating, mutilating limbs, overloading, and withholding food and drink. Any other interpretation is subject to individual choices and not authorized by scriptures. The Jain concept of ahimsa is very different from the concept of nonviolence found in other philosophies. Violence is usually associated with causing harm to others. But according to the Jain philosophy, violence refers primarily to injuring one's own self – behaviour which inhibits the soul's own ability to attain moksha (liberation from the cycle of births and deaths). At the same time it also implies violence to others because it is this tendency to harm others that ultimately harms one's own soul. Furthermore, the Jains extend the concept of ahimsa not only to humans but to all animals, plants, micro-organisms and all beings having life or life potential. All life is sacred and everything has a right to live fearlessly to its maximum potential. Living beings need not fear those who have taken the vow of ahimsa. According to Jainism, protection of life, also known as abhayadānam, is the supreme charity that a person can make. (Full article...) King in 1964 Martin Luther King Jr. (born Michael King Jr.; January 15, 1929 – April 4, 1968) was an American Baptist minister, activist, and political philosopher who was one of the most prominent leaders in the civil rights movement from 1955 until his assassination in 1968. King advanced civil rights for people of color in the United States through the use of nonviolent resistance and nonviolent civil disobedience against Jim Crow laws and other forms of legalized discrimination. A black church leader, King participated in and led marches for the right to vote, desegregation, labor rights, and other civil rights. He oversaw the 1955 Montgomery bus boycott and later became the first president of the Southern Christian Leadership Conference (SCLC). As president of the SCLC, he led the unsuccessful Albany Movement in Albany, Georgia, and helped organize some of the nonviolent 1963 protests in Birmingham, Alabama. King was one of the leaders of the 1963 March on Washington, where he delivered his "I Have a Dream" speech on the steps of the Lincoln Memorial, and helped organize two of the three Selma to Montgomery marches during the 1965 Selma voting rights movement. The civil rights movement achieved pivotal legislative gains in the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Fair Housing Act of 1968. There were several dramatic standoffs with segregationist authorities, who frequently responded violently. (Full article...) Representation of consciousness from the 17th century by Robert Fludd, an English Paracelsian physician Consciousness, at its simplest, is awareness of internal and external existence. However, its nature has led to millennia of analyses, explanations, and debate by philosophers, scientists, and theologians. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of it. In the past, it was one's "inner life", the world of introspection, of private thought, imagination, and volition. Today, it often includes any kind of cognition, experience, feeling, or perception. It may be awareness, awareness of awareness, metacognition, or self-awareness, either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked. Examples of the range of descriptions, definitions or explanations are: ordered distinction between self and environment, simple wakefulness, one's sense of selfhood or soul explored by "looking within"; being a metaphorical "stream" of contents, or being a mental state, mental event, or mental process of the brain. (Full article...) The illusory truth effect (also known as the illusion of truth effect, validity effect, truth effect, or the reiteration effect) is the tendency to believe false information to be correct after repeated exposure. This phenomenon was first identified in a 1977 study at Villanova University and Temple University. When truth is assessed, people rely on whether the information is in line with their understanding or if it feels familiar. The first condition is logical, as people compare new information with what they already know to be true. Repetition makes statements easier to process relative to new, unrepeated statements, leading people to believe that the repeated conclusion is more truthful. The illusory truth effect has also been linked to hindsight bias, in which the recollection of confidence is skewed after the truth has been received. In a 2015 study, researchers discovered that familiarity can overpower rationality and that repetitively hearing that a certain statement is wrong can paradoxically cause it to feel right. Researchers observed the illusory truth effect's impact even on participants who knew the correct answer to begin with but were persuaded to believe otherwise through the repetition of a falsehood, to "processing fluency".

The Upanishads (/ʊˈpʌnɪʃədz/; Sanskrit: उपनिषद्, IAST: Upaniṣad, pronounced [ˈʊpɐnɪʂɐd]) are late Vedic and post-Vedic Sanskrit texts that "document the transition from the archaic ritualism of the Veda into new religious ideas and institutions" and the emergence of the central religious concepts of Hinduism. They are the most recent addition to the Vedas, the oldest scriptures of Hinduism, and deal with meditation, philosophy, consciousness, and ontological knowledge. Earlier parts of the Vedas dealt with mantras, benedictions, rituals, ceremonies, and sacrifices. While among the most important literature in the history of Indian religions and culture, the Upanishads document a wide variety of "rites, incantations, and esoteric knowledge" departing from Vedic ritualism and interpreted in various ways in the later commentarial traditions. The Upanishads are widely known, and their diverse ideas, interpreted in various ways, informed later traditions of Hinduism. The central concern of all Upanishads is to discover the relations between ritual, cosmic realities (including gods), and the human body/person, postulating Ātman and Brahman as the "summit of the hierarchically arranged and interconnected universe," but various ideas about the relation between Atman and Brahman can be found.

Topics Glossary · Outline  · A–Z index  · Featured content Academic Branches of Philosophy Philosophy ponders the most fundamental questions humankind has been able to ask. These are increasingly numerous and over time they have been arranged into the overlapping branches of the philosophy tree: Aesthetics: What is art? What is beauty? Is there a standard of taste? Is art meaningful? If so, what does it mean? What is good art? Is art for the purpose of an end, or is "art for art's sake?" What connects us to art? How does art affect us? Is some art unethical? Can art corrupt or elevate societies? Epistemology: What are the nature and limits of knowledge? What is more fundamental to human existence, knowing (epistemology) or being (ontology)? How do we come to know what we know? What are the limits and scope of knowledge? How can we know that there are other minds (if we can)? How can we know that there is an external world (if we can)? How can we prove our answers? What is a true statement? Ethics: Is there a difference between ethically right and wrong actions (or values, or institutions)? If so, what is that difference? Which actions are right, and which wrong? Do divine commands make right acts right, or is their rightness based on something else? Are there standards of rightness that are absolute, or are all such standards relative to particular cultures? How should I live? What is happiness? Logic: What makes a good argument? How can I think critically about complicated arguments? What makes for good thinking? When can I say that something just does not make sense? Where is the origin of logic? Metaphysics: What sorts of things exist? What is the nature of those things? Do some things exist independently of our perception? What is the nature of space and time? What is the relationship of the mind to the body? What is it to be a person? What is it to be conscious? Do gods exist? Political philosophy: Are political institutions and their exercise of power justified? What is justice? Is there a 'proper' role and scope of government? Is democracy the best form of governance? Is governance ethically justifiable? Should a state be allowed? Should a state be able to promote the norms and values of a certain moral or religious doctrine? Are states allowed to go to war? Do states have duties against inhabitants of other states?
