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 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 about 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...)

A stamp of Zhang Heng issued by China Post in 1955 Zhang Heng (Chinese: 張衡; AD 78–139), formerly romanized Chang Heng, was a Chinese polymathic scientist and statesman who lived during the Eastern Han dynasty. Educated in the capital cities of Luoyang and Chang'an, he achieved success as an astronomer, mathematician, seismologist, hydraulic engineer, inventor, geographer, cartographer, ethnographer, artist, poet, philosopher, politician, and literary scholar. Zhang Heng began his career as a minor civil servant in Nanyang. Eventually, he became Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court. His uncompromising stance on historical and calendrical issues led to his becoming a controversial figure, preventing him from rising to the status of Grand Historian. His political rivalry with the palace eunuchs during the reign of Emperor Shun (r. 125–144) led to his decision to retire from the central court to serve as an administrator of Hejian Kingdom in present-day Hebei. Zhang returned home to Nanyang for a short time, before being recalled to serve in the capital once more in 138. He died there a year later, in 139. (Full article...) Cover of the first edition The Fountainhead is a 1943 novel by Russian-American author Ayn Rand, her first major literary success. The novel's protagonist, Howard Roark, is an intransigent young architect who battles against conventional standards and refuses to compromise with an architectural establishment unwilling to accept innovation. Roark embodies what Rand believed to be the ideal man, and his struggle reflects Rand's belief that individualism is superior to collectivism. Roark is opposed by what he calls "second-handers", who value conformity over independence and integrity. These include Roark's former classmate, Peter Keating, who succeeds by following popular styles but turns to Roark for help with design problems. Ellsworth Toohey, a socialist architecture critic who uses his influence to promote his political and social agenda, tries to destroy Roark's career. Tabloid newspaper publisher Gail Wynand seeks to shape popular opinion; he befriends Roark, then betrays him when public opinion turns in a direction he cannot control. The novel's most controversial character is Roark's lover, Dominique Francon. She believes that non-conformity has no chance of winning, so she alternates between helping Roark and working to undermine him. (Full article...) Priestley, painted late in life by Rembrandt Peale (c. 1800) Joseph Priestley (1733–1804) was a British natural philosopher, Dissenting clergyman, political theorist, theologian, and educator. He is best known for his discovery, simultaneously with Antoine Lavoisier, of oxygen gas. A member of marginalized religious groups throughout his life and a proponent of what was called "rational Dissent," Priestley advocated religious toleration and equal rights for Dissenters. He argued for extensive civil rights in works such as the important Essay on the First Principles of Government, believing that individuals could bring about progress and eventually the Millennium; he was the foremost British expounder of providentialism. Priestley also made significant contributions to education, publishing, among other things, The Rudiments of English Grammar, a seminal work on English grammar. In his most lasting contributions to education, he argued for the benefits of a liberal arts education and of the value of the study of modern history. In his metaphysical works, Priestley "attempt[ed] to combine theism, materialism, and determinism," a project that has been called "audacious and original." (Full article...) Portrait of Priestley, 1801 Joseph Priestley FRS (/ˈpriːstli/; 24 March 1733 – 6 February 1804) was an English chemist, Unitarian, natural philosopher, separatist theologian, grammarian, multi-subject educator and classical liberal political theorist. He published over 150 works, and conducted experiments in several areas of science. Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. (Full article...) Wollstonecraft c. 1797 Mary Wollstonecraft (UK: /ˈwʊlstənkrɑːft/ WUUL-stən-krahft, US: /-kræft/ -⁠kraft; 27 April 1759 – 10 September 1797) was an English writer and philosopher best known for her advocacy of women's rights. Until the late 20th century, Wollstonecraft's life, which encompassed several unconventional (at the time) personal relationships, received more attention than her writing. Wollstonecraft is regarded as one of the founding feminist philosophers, and feminists often cite both her life and her works as important influences. During her brief career she wrote novels, treatises, a travel narrative, a history of the French Revolution, a conduct book, and a children's book. Wollstonecraft is best known for A Vindication of the Rights of Woman (1792), in which she argues that women are not naturally inferior to men but appeared to be only because they lack education. She suggests that both men and women should be treated as rational beings and imagines a social order founded on reason. (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...) Bohr in 1922 Niels Henrik David Bohr (7 October 1885 – 18 November 1962) was a Danish theoretical physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. (Full article...) Archimedes Thoughtful by Fetti (1620) Archimedes of Syracuse (/ˌɑːrkɪˈmiːdiːz/ AR-kim-EE-deez; c. 287 – c. 212 BC) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, he is considered one of the leading scientists in classical antiquity. Regarded as the greatest mathematician of ancient history, and one of the greatest of all time, Archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems. These include the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral. Archimedes' other mathematical achievements include deriving an approximation of pi (π), defining and investigating the Archimedean spiral, and devising a system using exponentiation for expressing very large numbers. He was also one of the first to apply mathematics to physical phenomena, working on statics and hydrostatics. Archimedes' achievements in this area include a proof of the law of the lever, the widespread use of the concept of center of gravity, and the enunciation of the law of buoyancy known as Archimedes' principle. In astronomy, he made measurements of the apparent diameter of the Sun and the size of the universe. He is also credited with designing innovative machines, such as his screw pump, compound pulleys, and defensive war machines to protect his native Syracuse from invasion. (Full article...) Why Marx Was Right is a 2011 non-fiction book by the British academic Terry Eagleton about the 19th-century philosopher Karl Marx and the schools of thought, collectively known as Marxism, that arose from his work. Written for laypeople, Why Marx Was Right outlines ten objections to Marxism that they may hold and aims to refute each one in turn. These include arguments that Marxism is irrelevant owing to changing social classes in the modern world, that it is deterministic and utopian, and that Marxists oppose all reforms and believe in an authoritarian state. In his counterarguments, Eagleton explains how class struggle is central to Marxism, and that history is seen as a progression of modes of production, like feudalism and capitalism, involving the materials, technology and social relations required to produce goods and services within the society. Under a capitalist economy, the working class, known as the proletariat, are those lacking significant autonomy over their labour conditions, and have no control over the means of production. Eagleton describes how revolutions could lead to a new mode of production—socialism—in which the working class have control, and an eventual communist society could make the state obsolete. He explores the failures of the Soviet Union and other Marxist–Leninist countries. (Full article...) Du Bois in 1907 William Edward Burghardt Du Bois (/duːˈbɔɪs/ doo-BOYSS; February 23, 1868 – August 27, 1963) was an American sociologist, socialist, historian, and Pan-Africanist civil rights activist. Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. After completing graduate work at the Friedrich Wilhelm University in Berlin and Harvard University, where he was its first African American to earn a doctorate, Du Bois rose to national prominence as a leader of the Niagara Movement, a group of black civil rights activists seeking equal rights. Du Bois and his supporters opposed the Atlanta Compromise. Instead, Du Bois insisted on full civil rights and increased political representation, which he believed would be brought about by the African-American intellectual elite. He referred to this group as the talented tenth, a concept under the umbrella of racial uplift, and believed that African Americans needed the chances for advanced education to develop its leadership. (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...) Putnam in 2006 Hilary Whitehall Putnam (/ˈpʌtnəm/; July 31, 1926 – March 13, 2016) was an American philosopher, mathematician, computer scientist, and figure in analytic philosophy in the second half of the 20th century. He contributed to the studies of philosophy of mind, philosophy of language, philosophy of mathematics, and philosophy of science. Outside philosophy, Putnam contributed to mathematics and computer science. Together with Martin Davis he developed the Davis–Putnam algorithm for the Boolean satisfiability problem and he helped demonstrate the unsolvability of Hilbert's tenth problem. Putnam applied equal scrutiny to his own philosophical positions as to those of others, subjecting each position to rigorous analysis until he exposed its flaws. As a result, he acquired a reputation for frequently changing his positions. In philosophy of mind, Putnam argued against the type-identity of mental and physical states based on his hypothesis of the multiple realizability of the mental, and for the concept of functionalism, an influential theory regarding the mind–body problem. Putnam also originated the computational theory of mind. In philosophy of language, along with Saul Kripke and others, he developed the causal theory of reference, and formulated an original theory of meaning, introducing the notion of semantic externalism based on a thought experiment called Twin Earth. (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...) The title-page of the 1759 edition published by Cramer in Geneva, which reads, "Candide, or Optimism, translated from German by Dr. Ralph." Candide, ou l'Optimisme (/kɒnˈdiːd/ kon-DEED, French: [kɑ̃did] ⓘ) is a French satire written by Voltaire, a philosopher of the Age of Enlightenment, first published in 1759. The novella has been widely translated, with English versions titled Candide: or, All for the Best (1759); Candide: or, The Optimist (1762); and Candide: Optimism (1947). A young man, Candide, lives a sheltered life in an Edenic paradise, being indoctrinated with Leibnizian optimism by his mentor, Professor Pangloss. This lifestyle is abruptly ended, followed by Candide's slow and painful disillusionment as he witnesses and experiences great hardships in the world. Voltaire concludes Candide with, if not rejecting Leibnizian optimism outright, advocating a deeply practical precept, "we must cultivate our garden", in lieu of the Leibnizian mantra of Pangloss, "all is for the best" in the "best of all possible worlds". Candide is characterized by its tone as well as its erratic, fantastical, and fast-moving plot. A picaresque novel with a story akin to a serious bildungsroman, it parodies many adventure and romance clichés, in a tone that is bitter and matter-of-fact. The events discussed are often based on historical happenings. As philosophers of Voltaire's day contended with the problem of evil, so does Candide, albeit more directly and humorously. Voltaire ridicules religion, theologians, governments, armies, philosophies, and philosophers. Through Candide, he assaults Leibniz and his optimism. (Full article...) Mary Wollstonecraft by John Opie (c. 1791) The lifetime of British writer, philosopher, and feminist Mary Wollstonecraft (1759–1797) encompassed most of the second half of the eighteenth century, a time of great political and social upheaval throughout Europe and America: political reform movements in Britain gained strength, the American colonists successfully rebelled, and the French Revolution erupted. Wollstonecraft experienced only the headiest of these days, not living to see the end of the democratic revolution when Napoleon crowned himself emperor. Although Britain was still revelling in its mid-century imperial conquests and its triumph in the Seven Years' War, it was the French revolution that defined Wollstonecraft's generation. As poet Robert Southey later wrote: "few persons but those who have lived in it can conceive or comprehend what the memory of the French Revolution was, nor what a visionary world seemed to open upon those who were just entering it. Old things seemed passing away, and nothing was dreamt of but the regeneration of the human race." Part of what made reform possible in Britain in the second half of the eighteenth century was the dramatic increase in publishing; books, periodicals, and pamphlets became much more widely available than they had been just a few decades earlier. This increase in available printed material helped facilitate the rise of the British middle class. Reacting against what they viewed as aristocratic decadence, the new professional middle classes (made prosperous through British manufacturing and trade), offered their own ethical code: reason, meritocracy, self-reliance, religious toleration, free inquiry, free enterprise, and hard work. They set these values against what they perceived as the superstition and unreason of the poor and the prejudices, censorship, and self-indulgence of the rich. They also helped establish what has come to be called the "cult of domesticity", which solidified gender roles for men and women. This new vision of society rested on the writings of Scottish Enlightenment philosophers such as Adam Smith, who had developed a theory of social progress founded on sympathy and sensibility. A partial critique of the rationalist Enlightenment, these theories promoted a combination of reason and feeling that enabled women to enter the public sphere because of their keen moral sense. Wollstonecraft's writings stand at the nexus of all of these changes. Her educational works, such as her children's book Original Stories from Real Life (1788), helped inculcate middle-class values, and her two Vindications, A Vindication of the Rights of Men (1790) and A Vindication of the Rights of Woman (1792), argue for the value of an educated, rational populace, specifically one that includes women. In her two novels, Mary: A Fiction and Maria: or, The Wrongs of Woman, she explores the ramifications of sensibility for women. (Full article...)

Selected philosopher of the week John Dewey (October 20, 1859 – June 1, 1952) was an American philosopher, psychologist, and educational reformer, whose thoughts and ideas have been greatly influential in the United States and around the world. He, along with Charles Sanders Peirce and William James, is recognized as one of the founders of the philosophical school of Pragmatism. He is also known as the father of functional psychology; he was a leading representative of the progressive movement in U.S. education during the first half of the 20th century. Dewey was born in Burlington, Vermont of modest family origins. He graduated from the University of Vermont in 1879. He received his PhD from the Krieger School of Arts & Sciences at Johns Hopkins University in 1884. From 1904, he was professor of philosophy at both Columbia University and Teachers College, Columbia University. Along with the historian Charles A. Beard, economists Thorstein Veblen and James Harvey Robinson, Dewey is one of the founders of The New School for Social Research. Dewey's most significant writings were "The Reflex Arc Concept in Psychology" (1896), a critique of a standard psychological concept and the basis of all his further work; Human Nature and Conduct (1922), a study of the role of habit in human behavior; The Public and its Problems (1927), a defense of democracy written in response to Walter Lippmann's The Phantom Public (1925); Experience and Nature (1929), Dewey's most "metaphysical" statement; Art as Experience (1934), Dewey's major work on aesthetics; A Common Faith (1934), a humanistic study of religion; Logic: The Theory of Inquiry (1938), an examination of Dewey's unusual conception of logic; and Freedom and Culture (1939), a political work examining the roots of fascism. While each of these works focuses upon one particular philosophical theme, Dewey wove in all of his major themes into everything he wrote. In 1937, Dewey chaired a Commission of Enquiry which cleared Trotsky of the charges brought against him by Stalin. ...Archive Read more... Selected article of the week Philosophy of language is the reasoned inquiry into the nature, origins, and usage of language. As a topic, the philosophy of language for analytic philosophers is concerned with four central problems: the nature of meaning, language use, language cognition, and the relationship between language and reality. For continental philosophers, however, the philosophy of language tends to be dealt with, not as a separate topic, but as a part of logic, history or politics. (See the section "Language and Continental Philosophy" below.) First, philosophers of language inquire into the nature of meaning, and seek to explain what it means to "mean" something. Topics in that vein include the nature of synonymy, the origins of meaning itself, and how any meaning can ever really be known. Another project under this heading of special interest to analytic philosophers of language is the investigation into the manner in which sentences are composed into a meaningful whole out of the meaning of its parts. Second, they would like to understand what speakers and listeners do with language in communication, and how it is used socially. Specific interests may include the topics of language learning, language creation, and speech acts. Third, they would like to know how language relates to the minds of both the speaker and the interpreter. Of specific interest is the grounds for successful translation of words into other words. Finally, they investigate how language and meaning relate to truth and the world. Philosophers tend to be less concerned with which sentences are actually true, and more with what kinds of meanings can be true or false. A truth-oriented philosopher of language might wonder whether or not a meaningless sentence can be true or false, or whether or not sentences can express propositions about things that do not exist, rather than the way sentences are used.

The Iranian Enlightenment (Persian: روشنگری ایرانی), sometimes called the first generation of intellectual movements in Iran (Persian: نسل اول جنبش های روشنفکری در ایران), brought new ideas into traditional Iranian society from the mid-nineteenth to the early twentieth century. During the rule of the Qajar dynasty, and especially after the defeat of Iran in its war with the Russian Empire, cultural exchanges led to the formation of new ideas among the educated class of Iran.The establishment of Dar ul-Fonun, the first modern university in Iran and the arrival of foreign professors, caused the thoughts of European thinkers to enter Iran, followed by the first signs of enlightenment and intellectual movements in Iran. During this period, intellectual groups were formed in secret societies and secret associations. These secret societies included Mirza Malkam Khan's Faramosh Khaneh (based on Masonic lodges), Anjoman-e Okhovat, Society of Humanity and Mokhadarat Vatan Association. These groups spread their ideas by distributing leaflets and newspapers. These secret societies stressed the need to reform the land and administrative system and reduce the role of the clergy in society, as well as to limit the rulers within the framework of the law.

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...) David Émile Durkheim (/ˈdɜːrkhaɪm/; French: [emil dyʁkɛm] or [dyʁkajm]; 15 April 1858 – 15 November 1917) was a French sociologist. 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 Royal Commission on Animal Magnetism involved two entirely separate and independent French Royal Commissions, each appointed by Louis XVI in 1784, that were conducted simultaneously by a committee composed of four physicians from the Paris Faculty of Medicine (Faculté de médecine de Paris) and five scientists from the Royal Academy of Sciences (Académie des sciences) (i.e., the "Franklin Commission", named for Benjamin Franklin), and a second committee composed of five physicians from the Royal Society of Medicine (Société Royale de Médecine) (i.e., the "Society Commission"). Each Commission took five months to complete its investigations. The "Franklin" Report was presented to the King on 11 August 1784 – and was immediately published and very widely circulated throughout France and neighbouring countries – and the "Society" Report was presented to the King five days later on 16 August 1784.

He was ordained in the Baptist tradition in 1948. As a leader of the civil rights movement, he was a close friend and mentor of Martin Luther King Jr. He collaborated with King and E. D. Nixon to create the Montgomery Improvement Association, which led to the Montgomery bus boycott and co-created and was an executive board member of the Southern Christian Leadership Conference (SCLC). He became president of the SCLC following the assassination of King in 1968; he led the Poor People's Campaign in Washington, D.C., as well as other marches and demonstrations for disenfranchised Americans. He also served as an advisory committee member of the Congress on Racial Equality (CORE). In 1971, Abernathy addressed the United Nations, speaking about world peace. He also assisted in brokering a deal between the FBI and American Indian Movement protestors during the Wounded Knee incident of 1973. He retired from his position as president of the SCLC in 1977 and became president emeritus. Later that year, he unsuccessfully ran for the U.S. House of Representatives for the 5th district of Georgia. He later founded the Foundation for Economic Enterprises Development, and he testified before the U.S. Congress in support of extending the Voting Rights Act in 1982. (Full article...) Qing-era representation of Sun Tzu Sun Tzu was a Chinese military general, strategist, philosopher, and writer who lived during the Eastern Zhou period (771–256 BC). Sun Tzu is traditionally credited as the author of The Art of War, an influential work of military strategy that has affected both Western and East Asian philosophy and military thought. Sun Tzu is revered in Chinese and East Asian culture as a legendary historical and military figure. His birth name was Sun Wu and he was known outside of his family by his courtesy name Changqing. The name Sun Tzu—by which he is more popularly known—is an honorific which means "Master Sun". Sun Tzu mastered the military science of ancient China and created the military doctrine of asymmetrical warfare. According to it, an attack on the enemy should begin only after the enemy has no opportunity to either defend or counterattack. It was used in the wars in the era of the Warring States in ancient China (about 475–221 BC). Those combat combinations had specific names, descriptions and classifications. (Full article...) Power: A New Social Analysis by Bertrand Russell (1st imp. London 1938, Allen & Unwin, 328 pp.) is a work in social philosophy written by Bertrand Russell. Power, for Russell, is one's ability to achieve goals. In particular, Russell has in mind social power, that is, power over people. The volume contains a number of arguments. However, four themes have a central role in the overall work. The first theme given treatment in the analysis is that the lust for power is a part of human nature. Second, the work emphasises that there are different forms of social power, and that these forms are substantially interrelated. Third, Power insists that "organisations are usually connected with certain kinds of individuals". Finally, the work ends by arguing that "arbitrary rulership can and should be subdued".

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...)

Founded by working-class Russian expatriates in New York City in 1911, Golos Truda shifted to Petrograd during the Russian Revolution in 1917, when its editors took advantage of the general amnesty and right of return for political dissidents. There, the paper integrated itself into the anarchist labour movement, pronounced the necessity of a social revolution of and by the workers, and situated itself in opposition to the myriad of other left-wing movements. The rise to power of the Bolsheviks marked the turning point for the newspaper however, as the new government enacted increasingly repressive measures against the publication of dissident literature and against anarchist agitation in general, and after a few years of low-profile publishing, the Golos Truda collective was finally expunged by the Stalinist regime in 1929. (Full article...) Keynes in 1929 John Maynard Keynes, 1st Baron Keynes CB, FBA (/keɪnz/ KAYNZ; 5 June 1883 – 21 April 1946), was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream macroeconomics. He is known as the "father of macroeconomics". During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands. He argued that aggregate demand (total spending in the economy) determined the overall level of economic activity, and that inadequate aggregate demand could lead to prolonged periods of high unemployment, and since wages and labour costs are rigid downwards the economy will not automatically rebound to full employment. Keynes advocated the use of fiscal and monetary policies to mitigate the adverse effects of economic recessions and depressions. After the 1929 crisis, Keynes also turned away from a fundamental pillar of neoclassical economics: free trade. He criticized Ricardian comparative advantage theory (the foundation of free trade), considering the theory's initial assumptions unrealistic, and became definitively protectionist. He detailed these ideas in his magnum opus, The General Theory of Employment, Interest and Money, published in early 1936. By the late 1930s, leading Western economies had begun adopting Keynes's policy recommendations. Almost all capitalist governments had done so by the end of the two decades following Keynes's death in 1946. As a leader of the British delegation, Keynes participated in the design of the international economic institutions established after the end of World War II but was overruled by the American delegation on several aspects. (Full article...) Eliminative materialism (also called eliminativism) is a materialist position in the philosophy of mind. It is the idea that the majority of mental states in folk psychology do not exist. Some supporters of eliminativism argue that no coherent neural basis will be found for many everyday psychological concepts such as belief or desire, since they are poorly defined. The argument is that psychological concepts of behavior and experience should be judged by how well they reduce to the biological level. Other versions entail the nonexistence of conscious mental states such as pain and visual perceptions. Eliminativism about a class of entities is the view that the class of entities does not exist. For example, materialism tends to be eliminativist about the soul; modern chemists are eliminativist about phlogiston; modern biologists are eliminativist about élan vital; and modern physicists are eliminativist about luminiferous ether. Eliminative materialism is the relatively new (1960s–70s) idea that certain classes of mental entities that common sense takes for granted, such as beliefs, desires, and the subjective sensation of pain, do not exist. The most common versions are eliminativism about propositional attitudes, as expressed by Paul and Patricia Churchland, and eliminativism about qualia (subjective interpretations about particular instances of subjective experience), as expressed by Daniel Dennett, Georges Rey, and Jacy Reese Anthis. (Full article...) Aurobindo, c. 1900 Sri Aurobindo (born Aurobindo Ghose; 15 August 1872 – 5 December 1950) was an Indian philosopher, yogi, maharishi, poet, Educationalist and Indian nationalist. He was also a journalist, editing newspapers such as Bande Mataram. He joined the Indian movement for independence from British colonial rule, until 1910 was one of its influential leaders, and then became a spiritual reformer, introducing his visions on human progress and spiritual evolution. Aurobindo studied for the Indian Civil Service at King's College, in Cambridge, England. After returning to India he took up various civil service works under the Maharaja of the princely state of Baroda and became increasingly involved in nationalist politics in the Indian National Congress and the nascent revolutionary movement in Bengal with the Anushilan Samiti. He was arrested in the aftermath of a number of bombings linked to his organization in a public trial where he faced charges of treason for Alipore Conspiracy. However, Sri Aurobindo could only be convicted and imprisoned for writing articles against British colonial rule in India. He was released when no evidence could be provided, following the murder of a prosecution witness, Narendranath Goswami, during the trial. During his stay in the jail, he had mystical and spiritual experiences, after which he moved to Pondicherry, leaving politics for spiritual work. (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". (Full article...) Title page of first edition; 1889 Siddhantasara (pronounced [sɪd'ðantsar]; transl. The Gist of Principles) is a 1889 Gujarati book on the history of philosophy by Indian writer and philosopher Manilal Dwivedi. It is a historical critique of the world's religious philosophies. The book deals with the evolution of religious sentiment and attempts to establish the superiority of the Advaita philosophy over other religious philosophies. Siddhantasara received positive reviews and became a landmark in the history of Gujarati literature but was also criticised because of the logical lapses and inconsistencies in the author's arguments. Manishankar Bhatt (known as Kavi Kant) published his review as a book titled Siddhantasaranu Avalokan (Analysis of Siddhantasara). Siddhantasara is considered by critics to be Manilal's most important work, and has been seen as a response to the cultural agenda and reform activities of colonial India at the time.

The supreme God is Shiva, Shiva is Brahman, Brahman is Atman, Know your Atman, Know yourself to be that Brahman, states the Kaivalya Upanishad The Kaivalya Upanishad (Sanskrit: कैवल्य उपनिषद्) is an ancient Sanskrit text and one of the minor Upanishads of Hinduism. It is classified as a Shaiva Upanishad, and survives into modern times in two versions, one attached to the Krishna Yajurveda and other attached to the Atharvaveda. It is, as an Upanishad, a part of the corpus of Vedanta literature collection that presents the philosophical concepts of Hinduism. The Upanishad extols Shiva, aloneness and renunciation, describes the inner state of man in his personal spiritual journey detached from the world. The text is notable for presenting Shaivism in Vedanta, discussing Atman (Self) and its relation to Brahman, and Self-knowledge as the path to kaivalya (liberation). (Full article...)

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?
