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.
In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the pole star and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancers' compasses in regard to declination).

Sir Bernard Arthur Owen Williams, FBA (21 September 1929 – 10 June 2003) was an English moral philosopher. His publications include Problems of the Self (1973), Ethics and the Limits of Philosophy (1985), Shame and Necessity (1993), and Truth and Truthfulness (2002). He was knighted in 1999.
Emma Goldman (June 27, 1869 – May 14, 1940) was a Lithuanian-born anarchistrevolutionary, 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 OrthodoxLithuanian 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...)

A stamp of Zhang Heng issued by China Post in 1955
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...)
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)."
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 [de], 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...)
Born and raised in Albany, New York, Hand majored in philosophy at Harvard College and graduated with honors from Harvard Law School. After a relatively undistinguished career as a lawyer in Albany and New York City, he was appointed at the age of 37 as a Manhattan federal district judge in 1909. The profession suited his detached and open-minded temperament, and his decisions soon won him a reputation for craftsmanship and authority. Between 1909 and 1914, under the influence of Herbert Croly's social theories, Hand supported New Nationalism. He ran unsuccessfully as the Progressive Party's candidate for chief judge of the New York Court of Appeals in 1913, but withdrew from active politics shortly afterwards. In 1924, President Calvin Coolidge elevated Hand to the Court of Appeals for the Second Circuit, which he went on to lead as the senior circuit judge (later retitled chief judge) from 1939 until his semi-retirement in 1951. Scholars have recognized the Second Circuit under Hand as one of the finest appeals courts in American history. Friends and admirers often lobbied for Hand's promotion to the Supreme Court, but circumstances and his political past conspired against his appointment. (Full article...)

Confirmation bias (also confirmatory bias, myside bias, or congeniality bias) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs. Confirmation bias is insuperable for most people, but they can manage it, for example, by education and training in critical thinking skills.
Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects:
attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence)
belief perseverance (when beliefs persist after the evidence for them is shown to be false)
the irrational primacy effect (a greater reliance on information encountered early in a series)
illusory correlation (when people falsely perceive an association between two events or situations).
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...)

Wollstonecraft c. 1797
Mary Wollstonecraft (/ˈwʊlstənkræft/, also UK: /-krɑːft/; 27 April 1759 – 10 September 1797) was a British writer, philosopher, and advocate of women's rights. Until the late 20th century, Wollstonecraft's life, which encompassed several unconventional personal relationships at the time, 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 appear 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...)
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.

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 socialistarchitecture 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...)
Ion Heliade Rădulescu or Ion Heliade (also known as Eliade or Eliade Rădulescu; Romanian pronunciation:[ˈi.onheliˈaderəduˈlesku]; 6 January 1802 – 27 April 1872) was a Wallachian, later Romanian academic, Romantic and Classicist poet, essayist, memoirist, short story writer, newspaper editor and politician. A prolific translator of foreign literature into Romanian, he was also the author of books on linguistics and history. For much of his life, Heliade Rădulescu was a teacher at Saint Sava College in Bucharest, which he helped reopen. He was a founding member and first president of the Romanian Academy.
Heliade Rădulescu is considered one of the foremost champions of Romanian culture from the first half of the 19th century, having first risen to prominence through his association with Gheorghe Lazăr and his support of Lazăr's drive for discontinuing education in Greek. Over the following decades, he had a major role in shaping the modern Romanian language, but caused controversy when he advocated the massive introduction of Italianneologisms into the Romanian lexis. A Romantic nationalist landowner siding with moderate liberals, Heliade was among the leaders of the 1848 Wallachian revolution, after which he was forced to spend several years in exile. Adopting an original form of conservatism, which emphasized the role of the aristocratic boyars in Romanian history, he was rewarded for supporting the Ottoman Empire and clashed with the radical wing of the 1848 revolutionaries.

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.

Most of decision theory is normative or prescriptive, i.e. it is concerned with identifying the best decision to take, assuming an ideal decision taker who is fully informed, able to compute with perfect accuracy, and fully rational. The practical application of this prescriptive approach (how people should make decisions) is called decision analysis, and aimed at finding tools, methodologies and software to help people make better decisions. The most systematic and comprehensive software tools developed in this way are called decision support systems.
These are Good articles, which meet a core set of high editorial standards.

Moral blindness, also known as ethical blindness, is defined as a person's temporary inability to see the ethical aspect of a decision they are making. It is often caused by external factors due to which an individual is unable to see the immoral aspect of their behavior in that particular situation.
In his early career Whitehead wrote primarily on mathematics, logic, and physics. He wrote the three-volume Principia Mathematica (1910–1913), with his former student Bertrand Russell. Principia Mathematica is considered one of the twentieth century's most important works in mathematical logic, and placed 23rd in a list of the top 100 English-language nonfiction books of the twentieth century by Modern Library.

Title page of a Song dynasty (c. 1100) edition of the I Ching
The I Ching or Yijing (Chinese: 易經, Mandarin:[î tɕíŋ]ⓘ), usually translated Book of Changes or Classic of Changes, is an ancient Chinese divination text that is among the oldest of the Chinese classics. The I Ching was originally a divination manual in the Western Zhou period (1000–750 BC). Over the course of the Warring States and early imperial periods (500–200 BC), it transformed into a cosmological text with a series of philosophical commentaries known as the Ten Wings. After becoming part of the Chinese Five Classics in the 2nd century BC, the I Ching was the basis for divination practice for centuries across the Far East and was the subject of scholarly commentary. Between the 18th and 20th centuries, it took on an influential role in Western understanding of East Asian philosophical thought.[1] As a divination text, the I Ching is used for a Chinese form of cleromancy known as I Ching divination in which bundles of yarrow stalks are manipulated to produce sets of six apparently random numbers ranging from 6 to 9. Each of the 64 possible sets corresponds to a hexagram, which can be looked up in the I Ching. The hexagrams are arranged in an order known as the King Wen sequence. The interpretation of the readings found in the I Ching has been discussed and debated over the centuries. Many commentators have used the book symbolically, often to provide guidance for moral decision-making, as informed by Confucianism, Taoism and Buddhism. The hexagrams themselves have often acquired cosmological significance and been paralleled with many other traditional names for the processes of change such as yin and yang and Wu Xing.

Sir William Blackstone (10 July 1723 – 14 February 1780) was an English jurist, justice and Tory politician most noted for his Commentaries on the Laws of England, which became the best-known description of the doctrines of the English common law. Born into a middle-class family in London, Blackstone was educated at Charterhouse School before matriculating at Pembroke College, Oxford, in 1738. After switching to and completing a Bachelor of Civil Law degree, he was made a fellow of All Souls College, Oxford, on 2 November 1743, admitted to Middle Temple, and called to the Bar there in 1746. Following a slow start to his career as a barrister, Blackstone became heavily involved in university administration, becoming accountant, treasurer and bursar on 28 November 1746 and Senior Bursar in 1750. Blackstone is considered responsible for completing the Codrington Library and Warton Building, and simplifying the complex accounting system used by the college. On 3 July 1753 he formally gave up his practice as a barrister and instead embarked on a series of lectures on English law, the first of their kind. These were massively successful, earning him a total of £453 (£89,000 in 2023 terms), and led to the publication of An Analysis of the Laws of England in 1756, which repeatedly sold out and was used to preface his later works.
On 20 October 1759 Blackstone was confirmed as the first Vinerian Professor of English Law, immediately embarking on another series of lectures and publishing a similarly successful second treatise, titled A Discourse on the Study of the Law. With his growing fame, he successfully returned to the bar and maintained a good practice, also securing election as ToryMember of Parliament for the rotten borough of Hindon on 30 March 1761. In November 1765 he published the first of four volumes of Commentaries on the Laws of England, considered his magnum opus; the completed work earned Blackstone £14,000 (£2,459,000 in 2023 terms). After repeated failures, he successfully gained appointment to the judiciary as a justice of the Court of King's Bench on 16 February 1770, leaving to replace Edward Clive as a justice of the Common Pleas on 25 June. He remained in this position until his death, on 14 February 1780. (Full article...)
The Butterfly Dream, by Chinese painter Lu Zhi (c. 1550)
The Zhuangzi (Chinese: 莊子, historically romanized Chuang Tzŭ) is an ancient Chinese text that is one of the two foundational texts of Taoism, alongside the Tao Te Ching. It was written during the late Warring States period (476–221 BC) and is named for its traditional author, Zhuang Zhou.
The Zhuangzi consists of stories and maxims that exemplify the nature of the ideal Taoist sage. It contains numerous anecdotes, allegories, parables, and fables, often expressed with irreverence or humor. Recurring themes include embracing spontaneity and achieving freedom from the human world and its conventions. Throughout, the text aims to illustrate the arbitrariness and ultimate falsity of dichotomies normally embraced by human societies, such as those between good and bad, large and small, life and death, or human and nature. In contrast with the focus on good morals and personal duty expressed by many Chinese philosophers of the period, Zhuangzi promoted carefree wandering and following nature, through which one would ultimately become one with the "Way" (Tao).

Asa GrayForMemRS (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His Darwiniana was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator.
As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive network of specimen collectors. (Full article...)

"Behaviour with a purpose": a young springbokstotting. A biologist might argue that this has the function of signalling to predators, helping the springbok to survive and allowing it to reproduce.
Teleology in biology is the use of the language of goal-directedness in accounts of evolutionaryadaptation, which some biologists and philosophers of science find problematic. The term teleonomy has also been proposed. Before Darwin, organisms were seen as existing because God had designed and created them; their features such as eyes were taken by natural theology to have been made to enable them to carry out their functions, such as seeing. Evolutionary biologists often use similar teleological formulations that invoke purpose, but these imply natural selection rather than actual goals, whether conscious or not. Some biologists and religious thinkers held that evolution itself was somehow goal-directed (orthogenesis), and in vitalist versions, driven by a purposeful life force. With evolution working by natural selection acting on inherited variation, the use of teleology in biology has attracted criticism, and attempts have been made to teach students to avoid teleological language.
Quantum mechanics can describe many systems that classical physics cannot. Classical physics can describe many aspects of nature at an ordinary (macroscopic and (optical) microscopic) scale, but is not sufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic/microscopic) scale. (Full article...)

Mao in 1919
The early life of Chinese revolutionary and politician Mao Zedong covered the first 27 years of his life, from 1893 to 1919. Born in Shaoshanchong, Shaoshan in Hunan province, Mao grew up as the son of Mao Yichang, a wealthy farmer and landowner. Sent to the local Shaoshan Primary School, Mao was brought up in an environment of Confucianism, but reacted against this from an early age, developing political ideas from modern literature. Aged 13 his father organised a marriage for him with Luo Yigu, the daughter of another land-owning family, but Mao denounced the marriage and moved away from home.
In 1911 Mao began further education in the Hunanese capital of Changsha, where he came under the influence of republicanism, and became an admirer of republican revolutionary Sun Yat-Sen. When the Xinhai Revolution broke out between republicans and monarchists, Mao signed up as a soldier, although conflict subsided and he left the army after six months. Seeing himself as an intellectual, he became heavily influenced by classical liberalism, and began studying at the First Normal School of Changsha, as well as penning his first publications. With Xiao Zisheng he co-founded the Renovation of the People Study Society in April 1918 to discuss and perpetuate revolutionary ideas among students, before graduating in 1919. (Full article...)

Crime and Punishment (pre-reform Russian: Преступленіе и наказаніе; post-reform Russian: Преступление и наказание, romanized: Prestupleniye i nakazaniye, IPA:[prʲɪstʊˈplʲenʲɪjeɪnəkɐˈzanʲɪje]) is a novel by the Russian author Fyodor Dostoevsky. It was first published in the literary journal The Russian Messenger in twelve monthly installments during 1866. It was later published in a single volume. It is the second of Dostoevsky's full-length novels following his return from ten years of exile in Siberia. Crime and Punishment is considered the first great novel of his mature period of writing and is often cited as one of the greatest works of world literature.
Crime and Punishment follows the mental anguish and moral dilemmas of Rodion Raskolnikov, an impoverished ex-student in Saint Petersburg who plans to kill an unscrupulous pawnbroker, an old woman who stores money and valuable objects in her flat. He theorises that with the money he could liberate himself from poverty and go on to perform great deeds, and seeks to convince himself that certain crimes are justifiable if they are committed in order to remove obstacles to the higher goals of 'extraordinary' men. Once the deed is done, however, he finds himself wracked with confusion, paranoia, and disgust. His theoretical justifications lose all their power as he struggles with guilt and horror and is confronted with both internal and external consequences of his deed. (Full article...)
Born and raised in a Hindu family in coastal Gujarat, Gandhi trained in the law at the Inner Temple in London and was called to the bar in June 1891, at the age of 22. After two uncertain years in India, where he was unable to start a successful law practice, Gandhi moved to South Africa in 1893 to represent an Indian merchant in a lawsuit. He went on to live in South Africa for 21 years. There, Gandhi raised a family and first employed nonviolent resistance in a campaign for civil rights. In 1915, aged 45, he returned to India and soon set about organising peasants, farmers, and urban labourers to protest against discrimination and excessive land-tax. (Full article...)
Huygens first identified the correct laws of elastic collision in his work De Motu Corporum ex Percussione, completed in 1656 but published posthumously in 1703. In 1659, Huygens derived geometrically the formula in classical mechanics for the centrifugal force in his work De vi Centrifuga, a decade before Newton. In optics, he is best known for his wave theory of light, which he described in his Traité de la Lumière (1690). His theory of light was initially rejected in favour of Newton's corpuscular theory of light, until Augustin-Jean Fresnel adapted Huygens's principle to give a complete explanation of the rectilinear propagation and diffraction effects of light in 1821. Today this principle is known as the Huygens–Fresnel principle. (Full article...)

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?
