The Philosophy Portal A portal for Wikipedia's philosophy resources • 18,362 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...)

Image 1 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 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...) Image 2 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...) Image 3 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, while 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).

Image 4 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.

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...) Image 6 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. As Knightbridge Professor of Philosophy at the University of Cambridge and Deutsch Professor of Philosophy at the University of California, Berkeley, Williams became known for his efforts to reorient the study of moral philosophy to psychology, history, and in particular to the Greeks. Described by Colin McGinn as an "analytical philosopher with the soul of a general humanist," he was sceptical about attempts to create a foundation for moral philosophy. Martha Nussbaum wrote that he demanded of philosophy that it "come to terms with, and contain, the difficulty and complexity of human life." (Full article...) Image 7 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...) Image 8 Portrait of Rădulescu, by Mișu Popp Ion Heliade Rădulescu or Ion Heliade (also known as Eliade or Eliade Rădulescu; Romanian pronunciation: [ˈi.on heliˈade rəduˈlesku]; 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 Italian neologisms 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.

He independently conceived the theory of evolution through natural selection; his 1858 paper on the subject was published that year alongside extracts from Charles Darwin's earlier writings on the topic. It spurred Darwin to set aside the "big species book" he was drafting and quickly write an abstract of it, which was published in 1859 as On the Origin of Species. Wallace did extensive fieldwork, starting in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species, and is sometimes called the "father of biogeography", or more specifically of zoogeography.

Image 10 Title page from the second edition of A Vindication of the Rights of Men, the first to carry Wollstonecraft's name A Vindication of the Rights of Men, in a Letter to the Right Honourable Edmund Burke; Occasioned by His Reflections on the Revolution in France (1790) is a political pamphlet, written by the 18th-century British writer and women's rights advocate Mary Wollstonecraft, which attacks aristocracy and advocates republicanism. Wollstonecraft's was the first response in a pamphlet war sparked by the publication of Edmund Burke's Reflections on the Revolution in France (1790), a defense of constitutional monarchy, aristocracy, and the Church of England. Wollstonecraft attacked not only hereditary privilege, but also the rhetoric that Burke used to defend it. Most of Burke's detractors deplored what they viewed as his theatrical pity for Marie Antoinette, but Wollstonecraft was unique in her love of Burke's gendered language. By saying the sublime and the beautiful, terms first established by Burke himself in A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful (1756), she kept his rhetoric as well as his argument. In her first unabashedly feminist critique, which Wollstonecraft scholar Claudia Johnson describes as unsurpassed in its argumentative force, Wollstonecraft indicts Burke's justification of an equal society founded on the passivity of women.

Image 11 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...) Image 12 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...) Image 13 Bohr in 1922 Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish 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...) Image 14 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...) Image 15 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...)

Selected philosopher of the week Immanuel Kant 1724-1804 Immanuel Kant was a German philosopher from Königsberg in East Prussia (now Kaliningrad, Russia). He is regarded as one of the most influential thinkers of modern Europe and the last major philosopher of the Enlightenment. Kant defined the Enlightenment, in the essay "Answering the Question: What is Enlightenment?", as an age shaped by the motto, "Dare to know" (latin: Sapere aude). This involved thinking autonomously, free of the dictates of external authority. Kant's work served as a bridge between the Rationalist and Empiricist traditions of the 18th century. He had a decisive impact on the Romantic and German Idealist philosophies of the 19th century. His work has also been a starting point for many 20th century philosophers. ...Archive Read more... Selected article of the week The question "what is the meaning of life?" means different things to different people. The vagueness of the query is inherent in the word "meaning", which opens the question to many interpretations, such as: "What is the origin of life?", "What is the nature of life (and of the universe in which we live)?", "What is the significance of life?", "What is valuable in life?", and "What is the purpose of, or in, (one's) life?". These questions have resulted in a wide range of competing answers and arguments, from scientific theories, to philosophical, theological, and spiritual explanations. The Question "what is the meaning of life?" can also be simplified to say "why is anything alive?" or "what is the point in living". The answers below simply offer a guide to what is the purpose IN life, not what is the purpose OF life. "Life" itself must also be defined. For example, it could refer merely to the state of existing, or, the life-span of an individual or the achievements of an individual. This can also be applied to an entire species, a planet, or even the universe. ...Archive/schedule Read more...

Mount Baoding Buddhist Sculptures, Dazu, China. Filial piety has been an important aspect of Buddhist ethics since early Buddhism, and was essential in the apologetics and texts of Chinese Buddhism. In the Early Buddhist Texts such as the Nikāyas and Āgamas, filial piety is prescribed and practiced in three ways: to repay the gratitude toward one's parents; as a good karma or merit; and as a way to contribute to and sustain the social order. In Buddhist scriptures, narratives are given of the Buddha and his disciples practicing filial piety toward their parents, based on the qualities of gratitude and reciprocity. Initially, scholars of Buddhism like Kenneth Ch'en saw Buddhist teachings on filial piety as a distinct feature of Chinese Buddhism. Later scholarship, led by people such as John Strong and Gregory Schopen, has come to believe that filial piety was part of Buddhist doctrine since early times. Strong and Schopen have provided epigraphical and textual evidence to show that early Buddhist laypeople, monks and nuns often displayed strong devotion to their parents, concluding that filial piety was already an important part of the devotional life of early Buddhists. When Buddhism was introduced in China, it had no organized celibacy. Confucianism emphasized filial piety to parents and loyalty to the emperor, and Buddhist monastic life was seen to go against its tenets. In the 3rd–5th century, as criticism of Buddhism increased, Buddhist monastics and lay authors responded by writing about and translating Buddhist doctrines and narratives that supported filiality, comparing them to Confucianism and thereby defending Buddhism and its value in society. The Mouzi Lihuolun referred to Confucian and Daoist classics, as well as historical precedents to respond to critics of Buddhism. The Mouzi stated that while on the surface the Buddhist monk seems to reject and abandon his parents, he is actually aiding his parents as well as himself on the path towards enlightenment. Sun Chuo (c.300–380) further argued that monks were working to ensure the salvation of all people and making their family proud by doing so, and Liu Xie stated that Buddhists practiced filial piety by sharing merit with their departed relatives. Buddhist monks were also criticized for not expressing their respect to the Chinese emperor by prostrating and other devotion, which in Confucianism was associated with the virtue of filial piety. Huiyuan (334–416) responded that although monks did not express such piety, they did pay homage in heart and mind; moreover, their teaching of morality and virtue to the public helped support imperial rule.

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...) Image 3 Fourteenth-century drawing of angels turning the celestial spheres Ancient, medieval and Renaissance astronomers and philosophers developed many different theories about the dynamics of the celestial spheres. They explained the motions of the various nested spheres in terms of the materials of which they were made, external movers such as celestial intelligences, and internal movers such as motive souls or impressed forces. Most of these models were qualitative, although a few of them incorporated quantitative analyses that related speed, motive force and resistance. (Full article...) Image 4 Taoism or Daoism ( /ˈtaʊ.ɪzəm/ ⓘ, /ˈdaʊ.ɪzəm/ ⓘ) is a diverse philosophical and religious tradition indigenous to China, emphasizing harmony with the Tao 道 (pinyin: dào; Wade–Giles: tao4). With a range of meaning in Chinese philosophy, translations of Tao include 'way', 'road', 'path', or 'technique', generally understood in the Taoist sense as an enigmatic process of transformation ultimately underlying reality. Taoist thought has informed the development of various practices within the Taoist tradition and beyond, including forms of meditation, astrology, qigong, feng shui, and internal alchemy. A common goal of Taoist practice is self-cultivation, a deeper appreciation of the Tao, and more harmonious existence. Taoist ethics vary, but generally emphasize such virtues as effortless action, naturalness, simplicity, and the three treasures of compassion, frugality, and humility. The core of Taoist thought crystallized during the early Warring States period (c. 450 – c. 300 BCE), during which the epigrammatic Tao Te Ching and the anecdotal Zhuangzi—widely regarded as the fundamental texts of Taoist philosophy—were largely composed. They form the core of a body of Taoist writings accrued over the following centuries, which was assembled by monks into the Daozang canon starting in the 5th century CE. Early Taoism drew upon diverse influences, including the Shang and Zhou state religions, Naturalism, Mohism, Confucianism, various Legalist theories, as well as the I Ching and Spring and Autumn Annals.

"yoke" or "union") is a group of physical, mental, and spiritual practices or disciplines that originated in ancient India, aimed at controlling body and mind to attain various salvation goals, as practiced in the Hindu, Jain, and Buddhist traditions. Yoga may have pre-Vedic origins, but is first attested in the early first millennium BCE. It developed as various traditions in the eastern Ganges basin drew from a common body of practices, including Vedic elements. Yoga-like practices are mentioned in the Rigveda and a number of early Upanishads, but systematic yoga concepts emerge during the fifth and sixth centuries BCE in ancient India's ascetic and Śramaṇa movements, including Jainism and Buddhism. The Yoga Sutras of Patanjali, the classical text on Hindu yoga, samkhya-based but influenced by Buddhism, dates to the early centuries of the Common Era. Hatha yoga texts began to emerge between the ninth and 11th centuries, originating in tantra. (Full article...) Image 6 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...) Image 7 Title Page of first American edition Natural Theology or Evidences of the Existence and Attributes of the Deity is an 1802 work of Christian apologetics and philosophy of religion by the English clergyman William Paley (1743–1805). The book expounds his arguments from natural theology, making a teleological argument for the existence of God, notably beginning with the watchmaker analogy. The book was written in the context of the natural theology tradition. In earlier centuries, theologians such as John Ray and William Derham, as well as philosophers of classical times such as Cicero, argued for the existence and goodness of God from the general well-being of living things and the physical world.

Image 8 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.

Image 9 Icon of Gregory 14th-century fresco, Chora Church, Istanbul Gregory of Nyssa, also known as Gregory Nyssen (Greek: Γρηγόριος Νύσσης or Γρηγόριος Νυσσηνός; c. 335 – c. 394), was an early Roman Christian prelate who served as Bishop of Nyssa from 372 to 376 and from 378 until his death in 394. He is venerated as a saint in Eastern Orthodoxy, Catholicism, Oriental Orthodoxy, Anglicanism, and Lutheranism. Gregory, his elder brother Basil of Caesarea, and their friend Gregory of Nazianzus are collectively known as the Cappadocian Fathers. Gregory lacked the administrative ability of his brother Basil or the contemporary influence of Gregory of Nazianzus, but he was an erudite Christian theologian who made significant contributions to the doctrine of the Trinity and the Nicene Creed. Gregory's philosophical writings were influenced by Origen. Since the mid-twentieth century, there has been a significant increase in interest in Gregory's works from the academic community, particularly involving universal salvation, which has resulted in challenges to many traditional interpretations of his theology.

January 20], 1905 – March 6, 1982), better known by her pen name Ayn Rand (/aɪn/ EYEN), was a Russian-born American author and philosopher. She is known for her fiction and for developing a philosophical system she named Objectivism. Born and educated in Russia, she moved to the United States in 1926. After two early novels that were initially unsuccessful and two Broadway plays, Rand achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-selling work, the novel Atlas Shrugged. Afterward, until her death in 1982, she turned to non-fiction to promote her philosophy, publishing her own periodicals and releasing several collections of essays. Rand advocated reason and rejected faith and religion. She supported rational and ethical egoism as opposed to altruism and hedonism. In politics, she condemned the initiation of force as immoral and supported laissez-faire capitalism, which she defined as the system based on recognizing individual rights, including private property rights. Although she opposed libertarianism, which she viewed as anarchism, Rand is often associated with the modern libertarian movement in the United States. In art, she promoted romantic realism. She was sharply critical of most philosophers and philosophical traditions known to her, with a few exceptions. (Full article...) Image 11 Roman copy (in marble) of a Greek bronze bust of Aristotle by Lysippos (c. 330 BC), with modern alabaster mantle Aristotle (Greek: Ἀριστοτέλης Aristotélēs; 384–322 BC) was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science. Little is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At around eighteen years old, he joined Plato's Academy in Athens and remained there until the age of thirty seven (c. 347 BC). Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrus scrolls. (Full article...) Image 12 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...) Image 13 Nishidhi, a 14th-century memorial stone depicting the observance of the vow of Sallekhana with old Kannada inscription. Found at Tavanandi forest, Karnataka, India. Sallekhana (IAST: sallekhanā), also known as samlehna, santhara, samadhi-marana or sanyasana-marana, is a supplementary vow to the ethical code of conduct of Jainism. It is the religious practice of voluntarily fasting to death by gradually reducing the intake of food and liquids. It is viewed in Jainism as the thinning of human passions and the body, and another means of destroying rebirth-influencing karma by withdrawing all physical and mental activities. It is not considered a suicide by Jain scholars because it is not an act of passion, nor does it employ poisons or weapons. After the sallekhana vow, the ritual preparation and practice can extend into years. Sallekhana is a vow available to both Jain ascetics and householders. Historic evidence such as nishidhi engravings suggest sallekhana was observed by both men and women, including queens, in Jain history. However, in the modern era, death through sallekhana has been a relatively uncommon event. (Full article...) Image 14 Effigy from Peckham's tomb in Canterbury Cathedral John Peckham (c. 1230 – 8 December 1292) was a Franciscan friar and Archbishop of Canterbury in the years 1279–1292. Peckham studied at the University of Paris under Bonaventure, where he later taught theology and became known as a conservative opponent of Thomas Aquinas, especially regarding the nature of the soul. Peckham also studied optics and astronomy - his studies in those subjects were particularly influenced by Roger Bacon and Alhazen. Around 1270, Peckham returned to England, where he taught at the University of Oxford, and was elected the Franciscans provincial minister of England in 1275. After a brief stint in Rome, he was appointed Archbishop of Canterbury in 1279. His time as archbishop was marked by efforts to improve discipline in the clergy as well as reorganize the estates of his see. He served King Edward I of England in Wales. (Full article...) Image 15 Painting of Adi Shankara, exponent of Advaita Vedanta with his disciples by Raja Ravi Varma Adi Shankara (8th c. CE), also called Adi Shankaracharya (Sanskrit: आदि शङ्कर, आदि शङ्कराचार्य, romanized: Ādi Śaṅkara, Ādi Śaṅkarācārya, lit. 'First Shankaracharya', pronounced [aːd̪i ɕɐŋkɐraːt͡ɕaːrjɐ]), was an Indian Vedic scholar, philosopher and teacher (acharya) of Advaita Vedanta. Reliable information on Shankara's actual life is scanty, and his true impact lies in his "iconic representation of Hindu religion and culture," despite the fact that most Hindus do not adhere to Advaita Vedanta. Tradition also portrays him as the one who reconciled the various sects (Vaishnavism, Shaivism, and Saktism) with the introduction of the Pañcāyatana form of worship, the simultaneous worship of five deities – Ganesha, Surya, Vishnu, Shiva and Devi, arguing that all deities were but different forms of the one Brahman, the invisible Supreme Being. While often revered as the most important Indian philosopher, the historical influence of his works on Hindu intellectual thought has been questioned. Until the 10th century Shankara was overshadowed by his older contemporary Maṇḍana Miśra, and there is no mention of him in concurring Hindu, Buddhist or Jain sources until the 11th century. The popular image of Shankara started to take shape in the 14th century, centuries after his death, when Sringeri matha started to receive patronage from the kings of the Vijayanagara Empire and shifted their allegiance from Advaitic Agamic Shaivism to Brahmanical Advaita orthodoxy. Hagiographies dating from the 14th-17th centuries deified him as a ruler-renunciate, travelling on a digvijaya (conquest of the four quarters) across the Indian subcontinent to propagate his philosophy, defeating his opponents in theological debates. These hagiographies portray him as founding four mathas ("monasteries"), and Adi Shankara also came to be regarded as the organiser of the Dashanami monastic order, and the unifier of the Shanmata tradition of worship. The title of Shankaracharya, used by heads of certain monasteries in India, is derived from his name. (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?
