Left to right: Plato, Kant, Nietzsche, Buddha, Confucius, Averroes Philosophy (φιλοσοφία, '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...)

Bust of Shen at the Beijing Ancient Observatory Shen Kuo (Chinese: 沈括; 1031–1095) or Shen Gua, courtesy name Cunzhong (存中) and pseudonym Mengqi (now usually given as Mengxi) Weng (夢溪翁), was a Chinese polymath, scientist, and statesman of the Song dynasty (960–1279). Shen was a master in many fields of study including mathematics, optics, and horology. In his career as a civil servant, he became a finance minister, governmental state inspector, head official for the Bureau of Astronomy in the Song court, Assistant Minister of Imperial Hospitality, and also served as an academic chancellor. At court his political allegiance was to the Reformist faction known as the New Policies Group, headed by Chancellor Wang Anshi (1021–1085). 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).

Archimedes Thoughtful by Domenico Fetti (1620) Archimedes of Syracuse (/ˌɑːrkɪˈmiːdiːz/, ARK-ihm-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 regarded as one of the leading scientists in classical antiquity. Considered 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, 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. 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...) 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...) 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...) Conatus is, for Baruch Spinoza, where "each thing, as far as it lies in itself, strives to persevere in its being." In the philosophy of Baruch Spinoza, conatus (/koʊˈneɪtəs/; wikt:conatus; Latin for "effort; endeavor; impulse, inclination, tendency; undertaking; striving") is an innate inclination of a thing to continue to exist and enhance itself. This thing may be mind, matter, or a combination of both, and is often associated with God's will in a pantheist view of nature. The conatus may refer to the instinctive will to live of living organisms or to various metaphysical theories of motion and inertia. Today, conatus is rarely used in the technical sense, since classical mechanics uses concepts such as inertia and conservation of momentum that have superseded it. It has, however, been a notable influence on later thinkers such as Arthur Schopenhauer and Friedrich Nietzsche. (Full article...) Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there are no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists. Historically, evidence of atheistic viewpoints can be traced back to classical antiquity and early Indian philosophy. In the Western world, atheism declined as Christianity gained prominence. The 16th century and the Age of Enlightenment marked the resurgence of atheistic thought in Europe. Atheism achieved a significant position in the 20th century with legislation protecting freedom of thought. According to 2003 estimates, there are at least 500 million atheists in the world.

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. Today 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...) Intelligent design (ID) is a pseudoscientific argument for the existence of God, presented by its proponents as "an evidence-based scientific theory about life's origins". Proponents claim that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." ID is a form of creationism that lacks empirical support and offers no testable or tenable hypotheses, and is therefore not science. The leading proponents of ID are associated with the Discovery Institute, a Christian, politically conservative think tank based in the United States. Although the phrase intelligent design had featured previously in theological discussions of the argument from design, its first publication in its present use as an alternative term for creationism was in Of Pandas and People, a 1989 creationist textbook intended for high school biology classes. The term was substituted into drafts of the book, directly replacing references to creation science and creationism, after the 1987 Supreme Court's Edwards v. Aguillard decision barred the teaching of creation science in public schools on constitutional grounds. From the mid-1990s, the intelligent design movement (IDM), supported by the Discovery Institute, advocated inclusion of intelligent design in public school biology curricula. This led to the 2005 Kitzmiller v. Dover Area School District trial, which found that intelligent design was not science, that it "cannot uncouple itself from its creationist, and thus religious, antecedents", and that the public school district's promotion of it therefore violated the Establishment Clause of the First Amendment to the United States Constitution. (Full article...) Portrait, c. 1910 Billings Learned Hand (/ˈlɜːrnɪd/ LURN-id; January 27, 1872 – August 18, 1961) was an American jurist, lawyer, and judicial philosopher. He served as a federal trial judge on the U.S. District Court for the Southern District of New York from 1909 to 1924 and as a federal appellate judge on the U.S. Court of Appeals for the Second Circuit from 1924 to 1951. 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...) A stamp of Zhang Heng issued by China Post in 1955 Zhang Heng (Chinese: 張衡; AD 78–139), formerly romanized as 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...) Goldman, c. 1911 Emma Goldman (June 27, 1869 – May 14, 1940) was a Lithuanian-born anarchist revolutionary, political activist, and writer. She played a pivotal role in the development of anarchist political philosophy in North America and Europe in the first half of the 20th century. Born in Kaunas, Lithuania (then within the Russian Empire), to an Orthodox Lithuanian Jewish family, Goldman emigrated to the United States in 1885. Attracted to anarchism after the Chicago Haymarket affair, Goldman became a writer and a renowned lecturer on anarchist philosophy, women's rights, and social issues, attracting crowds of thousands. She and anarchist writer Alexander Berkman, her lover and lifelong friend, planned to assassinate industrialist and financier Henry Clay Frick as an act of propaganda of the deed. Frick survived the attempt on his life in 1892, and Berkman was sentenced to 22 years in prison. Goldman was imprisoned several times in the years that followed, for "inciting to riot" and illegally distributing information about birth control. In 1906, Goldman founded the anarchist journal Mother Earth. (Full article...) Portrait of Priestley, 1801 Joseph Priestley FRS (/ˈpriːstli/; 24 March 1733 – 6 February 1804) was an English chemist, natural philosopher, separatist theologian, grammarian, multi-subject educator, and 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...) "Lisa the Skeptic" is the eighth episode of the ninth season of the American animated television series The Simpsons. It first aired on the Fox network in the United States on November 23, 1997. On an archaeological dig with her class, Lisa discovers a skeleton that resembles an angel. All of the townspeople believe that the skeleton actually came from an angel, but skeptical Lisa attempts to persuade them that there must be a rational scientific explanation. The episode's writer, David X. Cohen, developed the idea after visiting the American Museum of Natural History, and decided to loosely parallel themes from the Scopes Monkey Trial. The episode also makes allusions to actual hoaxes, such as the Cardiff Giant. It has been discussed in the context of ontology, existentialism, and skepticism; it has also been used in Christian religious education classes to initiate discussion about angels, science, and faith. (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...) The title-page of the 1759 edition published by Cramer in Geneva, which reads, "Candide, or Optimism, translated from the 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). It begins with a young man, Candide, who is living a sheltered life in an Edenic paradise and being indoctrinated with Leibnizian optimism by his mentor, Professor Pangloss. The work describes the abrupt cessation of this lifestyle, 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 by its erratic, fantastical, and fast-moving plot. A picaresque novel with a story similar to that of a more serious coming-of-age narrative (bildungsroman), it parodies many adventure and romance clichés, the struggles of which are caricatured in a tone that is bitter and matter-of-fact. Still, the events discussed are often based on historical happenings, such as the Seven Years' War and the 1755 Lisbon earthquake. As philosophers of Voltaire's day contended with the problem of evil, so does Candide in this short theological novel, albeit more directly and humorously. Voltaire ridicules religion, theologians, governments, armies, philosophies, and philosophers. Through Candide, he assaults Leibniz and his optimism. (Full article...)

Selected philosopher of the week Machiavelli, c. 1500, in the robes of a Florentine public official. Niccolò Machiavelli (May 3, 1469 – June 21, 1527) was a Florentine political philosopher, musician, poet, and romantic comedic playwright. Machiavelli was also a key figure in realist political theory, crucial to European statecraft during the Renaissance. Machiavelli was born in Florence, the second son of Bernardo di Niccolò Machiavelli and his wife Bartolommea di Stefano Nelli. His father was a lawyer of some repute and belonged to an impoverished branch of an influential old Florentine family. ...Archive Read more... Selected article of the week Maximilian Carl Emil "Max" Weber (German pronunciation: [ˈmaks ˈveːbɐ]; 21 April 1864 – 14 June 1920) was a German philosopher, sociologist and political economist, who profoundly influenced social theory, social research, and the remit of sociology itself. Weber's major works dealt with the rationalization and so-called "disenchantment" which he associated with the rise of capitalism and modernity. Weber was, along with his associate Georg Simmel, a central figure in the establishment of methodological antipositivism; presenting sociology as a non-empirical field which must study social action through resolutely subjective means. He is typically cited, with Émile Durkheim and Karl Marx, as one of the three principal architects of modern social science, and has variously been described as the most important classic thinker in the social sciences.

In note on the left Vivekananda wrote: "One infinite pure and holy – beyond thought beyond qualities I bow down to thee". Swami Vivekananda (/ˈswɑːmi ˌvɪveɪˈkɑːnəndə/; Bengali: [ʃami bibekanɔndo] ⓘ; IAST: Svāmī Vivekānanda ; 12 January 1863 – 4 July 1902), born Narendranath Datta (Bengali: [nɔrendronatʰ dɔto]), was an Indian Hindu monk, philosopher, author, religious teacher, and the chief disciple of the Indian mystic Ramakrishna. He was a key figure in the introduction of Vedanta and Yoga to the Western world, and the father of modern Indian nationalism who is credited with raising interfaith awareness and bringing Hinduism to the status of a major world religion. Born into an aristocratic Bengali Kayastha family in Calcutta, Vivekananda was inclined from a young age towards religion and spirituality. He later found his guru Ramakrishna and became a monk. After the death of Ramakrishna, Vivekananda extensively toured the Indian subcontinent acquiring first-hand knowledge of the living conditions of Indian people in then British India. Moved by their plight, he resolved to help his countrymen and found a way to travel to the United States, where he became a popular figure after the 1893 Parliament of Religions in Chicago at which he delivered his famous speech beginning with the words: "Sisters and brothers of America ..." while introducing Hinduism to Americans. He was so impactful at the Parliament that an American newspaper described him as "an orator by divine right and undoubtedly the greatest figure at the Parliament". (Full article...) Lasker in 1929 Emanuel Lasker (German pronunciation: [eˈmaːnuɛl ˈlaskɐ] ⓘ; December 24, 1868 – January 11, 1941) was a German chess player, mathematician, and philosopher. He was the second World Chess Champion, holding the title for 27 years, from 1894 to 1921, the longest reign of any officially recognised World Chess Champion in history. In his prime, Lasker was one of the most dominant champions, and he is still generally regarded as one of the strongest players in history. His contemporaries used to say that Lasker used a "psychological" approach to the game, and even that he sometimes deliberately played inferior moves to confuse opponents. Recent analysis, however, indicates that he was ahead of his time and used a more flexible approach than his contemporaries, which mystified many of them. Lasker knew contemporary analyses of openings well but disagreed with many of them. He published chess magazines and five chess books, but later players and commentators found it difficult to draw lessons from his methods. (Full article...) Animal Rights Without Liberation: Applied Ethics and Human Obligations is a 2012 book by the British political theorist Alasdair Cochrane, in which it is argued that animal rights philosophy can be decoupled from animal liberation philosophy by the adoption of the interest-based rights approach. Cochrane, arguing that there is no reason that (nonhuman) animals should be excluded from justice, adopts Joseph Raz's account of interest rights and extends it to include animals. He argues that sentient animals possess a right not to be made to suffer and a right not to be killed, but not a right to freedom. The book's chapters apply Cochrane's account to a number of interactions between humans and animals; first animal experimentation, then animal agriculture, the genetic engineering of animals, the use of animals in entertainment and sport, the relationship of animals to environmental practices and the use of animals in cultural practices. The book is based upon Cochrane's doctoral thesis, which was completed at the London School of Economics, and builds upon subjects he had discussed in previous publications, including his first book. An Introduction to Animals and Political Theory. It was published by Columbia University Press as the second book in their series Critical Perspectives on Animals, edited by Gary Francione and Gary Steiner. Critics from a variety of backgrounds responded positively to the book, focussing on how Cochrane had found a middle ground between traditional animal rights philosophy and utilitarianism.

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.

Because of his controversially irreligious worldview, he is known as one of the "foremost atheists" of his time according to Nasser Rabbat. Born in the city of al-Ma'arra (present-day Ma'arrat al-Nu'man, Syria) during the later Abbasid era, he became blind at a young age from smallpox but nonetheless studied in nearby Aleppo, then in Tripoli and Antioch. Producing popular poems in Baghdad, he refused to sell his texts. In 1010, he returned to Syria after his mother began declining in health, and continued writing which gained him local respect. (Full article...) Philosophy of science is the branch of philosophy concerned with the foundations, methods, and implications of science. Amongst its central questions are the difference between science and non-science, the reliability of scientific theories, and the ultimate purpose and meaning of science as a human endeavour. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of scientific practice, and overlaps with metaphysics, ontology, logic, and epistemology, for example, when it explores the relationship between science and the concept of truth. Philosophy of science is both a theoretical and empirical discipline, relying on philosophical theorising as well as meta-studies of scientific practice. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science. There is little consensus among philosophers about many of the central problems concerned with the philosophy of science, including whether science can reveal the truth about unobservable things and whether scientific reasoning can be justified at all as leading to definite knowledge. In addition to these general question, philosophers of science consider problems that apply to particular sciences (such as biology, physics and social sciences such as economics and psychology). Some philosophers of science also use contemporary results in science to reach conclusions about philosophy itself. (Full article...) David Émile Durkheim (French: [emil dyʁkɛm] or [dyʁkajm], professionally known simply as Émile Durkheim; 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.

Born in New York City, he entered the Society of Jesus in 1917, and began his studies at Woodstock College. Following his undergraduate and graduate work there, he taught at Jesuit institutions in the Philippines until 1927. Following his ordination in 1930, he received doctorates in theology and philosophy from the Pontifical Gregorian University and the University of Paris, respectively. He then returned to the United States, where he became a professor of philosophy at Woodstock College and Fordham University. In 1943, Guthrie became the chairman of graduate philosophy at Georgetown University and dean of the Graduate School of Arts and Sciences. In this role, he admitted the first women to the school on equal terms as men. For twenty years, he promoted the belief that intellectuals must play a central role in combatting the ideologies that led to World War II. To that end, he was a member of the drafting committee of the UNESCO charter, was a co-founder of an American academy of Catholic intellectuals, and travelled the world with the U.S. State Department, for which he received honors from several countries and organizations.

Rothbard in the 1970s Murray Newton Rothbard (/ˈrɒθbɑːrd/; March 2, 1926 – January 7, 1995) was an American economist of the Austrian School, economic historian, political theorist, and activist. Rothbard was a central figure in the 20th-century American libertarian movement, particularly its right-wing strands, and was a founder and leading theoretician of anarcho-capitalism. He wrote over twenty books on political theory, history, economics, and other subjects. Rothbard argued that all services provided by the "monopoly system of the corporate state" could be provided more efficiently by the private sector and wrote that the state is "the organization of robbery systematized and writ large". He called fractional-reserve banking a form of fraud and opposed central banking. He categorically opposed all military, political, and economic interventionism in the affairs of other nations. (Full article...) Batman: Anarky is a 1999 trade paperback published by DC Comics. The book collects prominent appearances of Anarky, a comic book character created by Alan Grant and Norm Breyfogle. Although all of the collected stories were written by Alan Grant, various artists contributed to individual stories. Dual introductions were written by the creators - both of whom introduce the character and give insight into their role in Anarky's creation and development. Featured as an antagonist in various Batman comics during the '90s, stories based on the character were highly thematic, political, and philosophical in tone. The majority of the collected stories ("Anarky in Gotham City", "Anarky: Tomorrow Belongs to Us", "Anarky") are influenced by the philosophy of anarchism, while the final story ("Metamorphosis") is influenced by Frank R. Wallace. Although anti-statism is the overarching theme of the collection, other concepts are explored. Anarky's characterization was expanded throughout the stories to present him first as a libertarian socialist and anarchist, and in the final story as a vehicle for explorations into atheism, rationalism, and bicameral mentality.

Statue of Shiva performing yoga in the lotus position Yoga (/ˈjoʊɡə/ ⓘ; Sanskrit: योग, lit. 'yoke' or 'union' pronounced [joːɡɐ]) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India and aim to control (yoke) and still the mind, recognizing a detached witness-consciousness untouched by the mind (Chitta) and mundane suffering (Duḥkha). There is a wide variety of schools of yoga, practices, and goals in Hinduism, Buddhism, and Jainism, and traditional and modern yoga is practiced worldwide. Yoga-like practices were first mentioned in the ancient Hindu text known as Rigveda. Yoga is referred to in a number of the Upanishads. The first known appearance of the word "yoga" with the same meaning as the modern term is in the Katha Upanishad, which was probably composed between the fifth and third centuries BCE. Yoga continued to develop as a systematic study and practice during the fifth and sixth centuries BCE in ancient India's ascetic and Śramaṇa movements. The most comprehensive text on yoga, the Yoga Sutras of Patanjali, date to the early centuries of the Common Era; Yoga philosophy became known as one of the six orthodox philosophical schools (Darśanas) of Hinduism in the second half of the first millennium CE. Hatha yoga texts began to emerge between the ninth and 11th centuries, originating in tantra. (Full article...) Gargi Vachaknavi (Sans: गार्गी वाचक्नवी (Devanagari); Gargi Vacaknavi (HK)), was an ancient Indian sage and philosopher. In Vedic literature, she is honoured as a great natural philosopher, renowned expounder of the Vedas, and known as Brahmavadini, a person with knowledge of Brahma Vidya. In the Sixth and the eighth Brahmana of Brihadaranyaka Upanishad, her name is prominent as she participates in the brahmayajna, a philosophic debate organized by King Janaka of Videha and she challenges the sage Yajnavalkya with perplexing questions on the issue of atman (soul). She is also said to have written many hymns in the Rigveda. She remained a celibate all her life and was held in veneration by the conventional Hindus. Gargi, the daughter of sage Vachaknu in the lineage of sage Garga (c. 800-500 BCE) was named after her father Gargi Vachaknavi. From a young age, she evinced a keen interest in Vedic scriptures and became very proficient in fields of philosophy. She became highly knowledgeable in the Vedas and Upanishads in the Vedic times and held intellectual debates with other philosophers. (Full article...) Arendt in 1933 Hannah Arendt (/ˈɛərənt, ˈɑːr-/, US also /əˈrɛnt/, German: [ˌhana ˈaːʁənt] ⓘ; born Johanna Arendt; 14 October 1906 – 4 December 1975) was a German-American historian and philosopher. She was one of the most influential political theorists of the 20th century. Her works cover a broad range of topics, but she is best known for those dealing with the nature of power and evil, as well as politics, direct democracy, authority, and totalitarianism. She is also remembered for the controversy surrounding the trial of Adolf Eichmann, her attempt to explain how ordinary people become actors in totalitarian systems, which was considered by some an apologia, and for the phrase "the banality of evil." She is commemorated by institutions and journals devoted to her thinking, the Hannah Arendt Prize for political thinking, and on stamps, street names, and schools, amongst other things.

He had perhaps the widest coverage of any mathematician of his time, integrating pure and applied sciences and making major contributions to many fields, including mathematics, physics, economics, computing, and statistics. He was a pioneer in building the mathematical framework of quantum physics, in the development of functional analysis, and in game theory, introducing or codifying concepts including cellular automata, the universal constructor and the digital computer. His analysis of the structure of self-replication preceded the discovery of the structure of DNA. During World War II, von Neumann worked on the Manhattan Project. He developed the mathematical models behind the explosive lenses used in the implosion-type nuclear weapon. Before and after the war, he consulted for many organizations including the Office of Scientific Research and Development, the Army's Ballistic Research Laboratory, the Armed Forces Special Weapons Project and the Oak Ridge National Laboratory. At the peak of his influence in the 1950s, he chaired a number of Defense Department committees including the Strategic Missile Evaluation Committee and the ICBM Scientific Advisory Committee. He was also a member of the influential Atomic Energy Commission in charge of all atomic energy development in the country. He played a key role alongside Bernard Schriever and Trevor Gardner in the design and development of the United States' first ICBM programs. At that time he was considered the nation's foremost expert on nuclear weaponry and the leading defense scientist at the U.S. Department of Defense. (Full article...) Buddha image with scenes of stories in which he repaid his parents. 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.

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?
