Philosophy (from Ancient Greek philosophía lit. 'love of wisdom') is a systematic study of general and fundamental questions concerning topics like existence, knowledge, mind, reason, language, and value. It is a rational and critical inquiry that reflects on its methods and assumptions.

Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western, Arabic–Persian, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues about right social conduct, government, and self-cultivation.

Major branches of philosophy are epistemology, ethics, logic, and metaphysics. Epistemology studies what knowledge is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic is the study of correct reasoning and explores how good arguments can be distinguished from bad ones. Metaphysics examines the most general features of reality, existence, objects, and properties. Other subfields are aesthetics, philosophy of language, philosophy of mind, philosophy of religion, philosophy of science, philosophy of mathematics, philosophy of history, and political philosophy. Within each branch, there are competing schools of philosophy that promote different principles, theories, or methods.

Philosophers use a great variety of methods to arrive at philosophical knowledge. They include conceptual analysis, reliance on common sense and intuitions, use of thought experiments, analysis of ordinary language, description of experience, and critical questioning. Philosophy is related to many other fields, such as the natural and social 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...)

First edition title page

A Vindication of the Rights of Woman: with Strictures on Political and Moral Subjects is a 1792 essay by British philosopher and women's rights advocate Mary Wollstonecraft. It is considered a feminist or, more precisely, proto-feminist piece, and one of the pioneering works in the tradition now known as feminist philosophy.

In this essay, Wollstonecraft refutes those educational and political theorists of the eighteenth century who did not believe women should receive a full 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 specifically calls for equality between the sexes in particular areas of life, especially moral responsibility and educational access. Uncertainty regarding whether she believed women should have full voting rights or other political rights make it difficult to classify Wollstonecraft definitively as a modern feminist; furthermore, the word feminist did not emerge until decades after her death.

"Lisa the Skeptic" is the eighth episode of the ninth season of the American animated television series The Simpsons. It first aired on Fox 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...)

Du Bois in 1907

William Edward Burghardt Du Bois (/duːˈbɔɪs/ doo-BOYSS; February 23, 1868 – August 27, 1963) was an American sociologist, writer, historian, and Pan-Africanist civil rights activist. Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. He completed graduate work at Harvard University, where he was the first African American to earn a doctorate. He was a professor at Atlanta University and over the course of his life wrote a large number of books and articles. He spent the last years of his life in Ghana and died in Accra on August 27, 1963.

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 chance for advanced education to develop their leadership. Du Bois was one of the founders of the National Association for the Advancement of Colored People (NAACP) in 1909. Du Bois used his position in the NAACP to respond to racist incidents.

1897 illustration of La Peau de chagrin, drawn by Adrien Moreau and published by George Barrie & Son

La Peau de chagrin (French pronunciation: [la po də ʃaɡʁɛ̃], The Skin of Shagreen), known in English as The Magic Skin and The Wild Ass's Skin, is an 1831 novel by French novelist and playwright Honoré de Balzac (1799–1850). Set in early 19th-century Paris, it tells the story of a young man who finds a magic piece of shagreen (untanned skin from a wild ass) that fulfills his every desire. For each wish granted, however, the skin shrinks and consumes a portion of his physical energy. La Peau de chagrin belongs to the Études philosophiques group of Balzac's sequence of novels, La Comédie humaine.

Before the book was completed, Balzac created excitement about it by publishing a series of articles and story fragments in several Parisian journals. Although he was five months late in delivering the manuscript, he succeeded in generating sufficient interest that the novel sold out instantly upon its publication. A second edition, which included a series of twelve other "philosophical tales", was released one month later. (Full article...)

Ion Heliade Rădulescu or Ion Heliade (also known as Eliade or Eliade Rădulescu; Romanian pronunciation: [ˈi.on (h)eliˈade 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.

Athonite Fresco Icon of Saint Maximos the Confessor

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.

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".

The leading proponents of ID are associated with the Discovery Institute, a Christian, politically conservative think tank based in the United States.
ID is a form of creationism that lacks empirical support and offers no testable or tenable hypotheses, and is therefore not science. (Full article...)

Eric Alfred Havelock (/ˈhævlɒk/; 3 June 1903 – 4 April 1988) was a British classicist who spent most of his life in Canada and the United States. He was a professor at the University of Toronto and was active in the Canadian socialist movement during the 1930s. In the 1960s and 1970s, he served as chair of the classics departments at both Harvard and Yale. Although he was trained in the turn-of-the-20th-century Oxbridge tradition of classical studies, which saw Greek intellectual history as an unbroken chain of related ideas, Havelock broke radically with his own teachers and proposed an entirely new model for understanding the classical world, based on a sharp division between literature of the 6th and 5th centuries BC on the one hand, and that of the 4th on the other.

Much of Havelock's work was devoted to addressing a single thesis: that all of Western thought is informed by a profound shift in the kinds of ideas available to the human mind at the point that Greek philosophy converted from an oral to a literate form. The idea has been controversial in classical studies, and has been rejected outright both by many of Havelock's contemporaries and modern classicists. Havelock and his ideas have nonetheless had far-reaching influence, both in classical studies and other academic areas. He and Walter J. Ong (who was himself strongly influenced by Havelock) essentially founded the field that studies transitions from orality to literacy, and Havelock has been one of the most frequently cited theorists in that field; as an account of communication, his work profoundly affected the media theories of Harold Innis and Marshall McLuhan. Havelock's influence has spread beyond the study of the classical world to that of analogous transitions in other times and places. (Full article...)

Wallace in 1895

Alfred Russel Wallace (8 January 1823 – 7 November 1913) was an English naturalist, explorer, geographer, anthropologist, biologist and illustrator. 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 writings on the topic. It spurred Darwin to set aside the "big species book" he was drafting and to 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.

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.

Lenin in 1920

Vladimir Ilyich Ulyanov (22 April [O.S. 10 April] 1870 – 21 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist. He was the first head of government of Soviet Russia from 1917 until his death in 1924 and of the Soviet Union from 1922 until his death. As the Bolsheviks' founder, Lenin led the October Revolution, which established the world's first communist state. His government won the Russian Civil War and created a one-party state under the Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism.

Lenin embraced revolutionary socialist politics after his brother was executed in 1887 for plotting to assassinate Tsar Alexander III. He was expelled from Kazan Imperial University for participating in student protests, and earned a law degree before moving to Saint Petersburg in 1893 and becoming a prominent Marxist activist. In 1897, Lenin was exiled to Siberia for three years, after which he moved to Western Europe, including Switzerland, and became a leading figure in the Russian Social Democratic Labour Party. In 1903, the party split between Lenin's Bolshevik faction and the Mensheviks, with Lenin advocating for a vanguard party to lead the proletariat in establishing socialism. Lenin briefly returned to Russia during the Revolution of 1905. During the First World War, he campaigned for its transformation into a Europe-wide proletarian revolution. After the February Revolution of 1917 ousted Tsar Nicholas II, Lenin returned to Russia and played a leading role in the October Revolution. (Full article...)

Title page from the first edition of Locke's Some Thoughts Concerning Education (1693)

Some Thoughts Concerning Education is a 1693 treatise on the education of gentlemen written by the English philosopher John Locke. For over a century, it was the most important philosophical work on education in England. It was translated into almost all of the major written European languages during the eighteenth century, and nearly every European writer on education after Locke, including Jean-Jacques Rousseau, acknowledged its influence.

In his Essay Concerning Human Understanding (1690), Locke outlined a new theory of mind, contending that the mind is originally a tabula rasa or "blank slate"; that is, it did not contain any innate ideas at birth. Some Thoughts Concerning Education explains how to educate that mind using three distinct methods: the development of a healthy body; the formation of a virtuous character; and the choice of an appropriate academic curriculum.

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 Northern Song dynasty. 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).

Title page, 1798

Maria: or, The Wrongs of Woman is Mary Wollstonecraft's unfinished novelistic sequel to her revolutionary political treatise A Vindication of the Rights of Woman (1792). The Wrongs of Woman was published posthumously in 1798 by her husband, William Godwin, and is often considered her most radical feminist work.

Wollstonecraft's philosophical and gothic novel revolves around the story of a woman imprisoned in an insane asylum by her husband. It focuses on the societal rather than the individual "wrongs of woman" and criticizes what Wollstonecraft viewed as the patriarchal institution of marriage in eighteenth-century Britain and the legal system that protected it. However, the heroine's inability to relinquish her romantic fantasies also reveals women's collusion in their oppression through false and damaging sentimentalism. The novel pioneered the celebration of female sexuality and cross-class identification between women. Such themes, coupled with the publication of Godwin's scandalous Memoirs of Wollstonecraft's life, made the novel unpopular at the time it was published. (Full article...)

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, values, or decisions. 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, emotionally charged issues and deeply entrenched beliefs.

Biased search for information, biased interpretation of this information and biased memory recall have been invoked to explain four specific effects:
1. attitude polarization (when a disagreement becomes more extreme despite the different parties being exposed to the same evidence)
2. belief perseverance (when beliefs persist after the evidence for them is shown to be false)
3. the irrational primacy effect (a greater reliance on information encountered early in a series)
4. illusory correlation (when people falsely perceive an association between two events or situations).

Selected philosopher of the week

Willard Van Orman Quine (1908–2000) was an analytic philosopher who became a main proponent of the view that philosophy is not conceptual analysis. His paper "Two Dogmas of Empiricism" attacked two central aspects of logical positivism by blurring the line in the analytic-synthetic distinction and by rejecting reductionism. He propounded the indeterminacy of translation thesis through ontological relativity, a holist view that all theories are under-determined by empirical data. Quine also made contributions to logic, particularly set theory. He popularized the phrases "hold come what may" and "hold more stubbornly at least."

Selected article of the week

Phenomenology is a current in philosophy that takes the intuitive experience of phenomena (what presents itself to us in conscious experience) as its starting point and tries to extract from it the essential features of experiences and the essence of what we experience. It stems from the School of Brentano and was mostly based on the work of the 20th century philosopher Edmund Husserl, and was developed further by philosophers such as Martin Heidegger, Maurice Merleau-Ponty, Max Scheler, Hannah Arendt, and Emmanuel Levinas. As such, phenomenological thought influenced the development of existential phenomenology and existentialism in France, as is clear from the work of Jean-Paul Sartre and Simone de Beauvoir, and Munich phenomenology (Johannes Daubert, Adolf Reinach in Germany and Alfred Schütz in Austria).

While the term "phenomenology" was used several times in the history of philosophy before Husserl, modern use ties it more explicitly to his particular method.

Alvin Plantinga in 2004

Alvin Plantinga's free-will defense is a logical argument developed by the American analytic philosopher Alvin Plantinga and published in its final version in his 1977 book God, Freedom, and Evil. Plantinga's argument is a defense against the logical problem of evil as formulated by the philosopher J. L. Mackie beginning in 1955. Mackie's formulation of the logical problem of evil argued that three attributes ascribed to God (omniscience, omnipotence, and omnibenevolence) are logically incompatible with the existence of evil.

Marcellina was an early Christian Carpocratian religious leader in the mid-second century AD known primarily from the writings of Irenaeus and Origen. She originated in Alexandria, but moved to Rome during the episcopate of Anicetus (c. 157 – 168). She attracted large numbers of followers and founded the Carpocratian sect of Marcellians. Like other Carpocratians, Marcellina and her followers believed in antinomianism, also known as libertinism, the idea that obedience to laws and regulations is unnecessary in order to attain salvation. They believed that Jesus was only a man, but saw him as a model to be emulated, albeit one which a believer was capable of surpassing. Marcellina's community appears to have sought to literally implement the foundational Carpocratian teaching of social egalitarianism. The Marcellians in particular are reported to have branded their disciples on the insides of their right earlobes and venerated images of Jesus as well as Greek philosophers such as Pythagoras, Plato, and Aristotle. Although the Marcellians identified themselves as "gnostics", many modern scholars do not classify them as members of the sect of Gnosticism. (Full article...)

Header of the first Russian edition, published August 11, 1917

Golos Truda (Russian: Голос Труда, lit. 'The Voice of Labour') was a Russian-language anarchist newspaper. Founded by working-class Russian expatriates in New York City in 1911, Golos Truda shifted to Petrograd during the Russian Revolution in 1917, when its editors took advantage of the general amnesty and right of return for political dissidents. There, the paper integrated itself into the anarchist labour movement, pronounced the necessity of a social revolution of and by the workers, and situated itself in opposition to the myriad of other left-wing movements.

The rise to power of the Bolsheviks marked the turning point for the newspaper however, as the new government enacted increasingly repressive measures against the publication of dissident literature and against anarchist agitation in general, and after a few years of low-profile publishing, the Golos Truda collective was finally expunged by the Stalinist regime in 1929.

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...)

It was founded by the archaeologist James Burgess to enable the sharing of knowledge between scholars based in Europe and in India and was notable for the high quality of its epigraphic illustrations which enabled scholars to make accurate translations of texts that in many cases remain the definitive versions to this day. It was also pioneering in its recording of Indian folklore. It was succeeded by The New Indian Antiquary (1938–47) and the Indian Antiquary (1964–71). (Full article...)

Cochrane in 2013

Alasdair Cochrane (born 31 March 1978) is a British political theorist and ethicist who is currently Professor of Political Theory in the Department of Politics and International Relations at the University of Sheffield. He is known for his work on animal rights from the perspective of political theory, which is the subject of his two books: An Introduction to Animals and Political Theory (2010, Palgrave Macmillan) and Animal Rights Without Liberation (2012, Columbia University Press). His third book, Sentientist Politics, was published by Oxford University Press in 2018. He is a founding member of the Centre for Animals and Social Justice, a UK-based think tank focused on furthering the social and political status of nonhuman animals. He joined the Department at Sheffield in 2012, having previously been a faculty member at the Centre for the Study of Human Rights, London School of Economics. Cochrane is a sentientist. Sentientism is a naturalistic worldview that grants moral consideration to all sentient beings.

Cochrane's work forms part of the political turn in animal ethics—that is, the emergence of academic literature exploring the normative aspects of human/nonhuman animal relationships from a political perspective. He is known for his interest-based account of animal rights, a theory of justice according to which animals have rights based on their possession of normatively-significant interests. The account is a two-tiered one, with individuals' strong interests grounding prima facie rights, and some prima facie rights becoming concrete, or all-things-considered, rights. In this picture, the violation of concrete rights, but not necessarily prima facie rights, represents an injustice. In particular, Cochrane argues that sentient animals' interests against suffering and death ground prima facie rights against the infliction of suffering and death. These prima facie rights convert to concrete rights in, for example, animal agriculture and animal testing, meaning that killing nonhuman animals or making them suffer for these purposes is unjust.

Merit, demerit and its retributions at the level of the individual. Based on Spiro.

Merit (Sanskrit: puṇya; Pali: puñña) is a concept considered fundamental to Buddhist ethics. It is a beneficial and protective force which accumulates as a result of good deeds, acts, or thoughts. Merit-making is important to Buddhist practice: merit brings good and agreeable results, determines the quality of the next life and contributes to a person's growth towards enlightenment. In addition, merit is also shared with a deceased loved one, in order to help the deceased in their new existence. Despite modernization, merit-making remains essential in traditional Buddhist countries and has had a significant impact on the rural economies in these countries.

Merit is connected with the notions of purity and goodness. Before Buddhism, merit was used with regard to ancestor worship, but in Buddhism it gained a more general ethical meaning. Merit is a force that results from good deeds done; it is capable of attracting good circumstances in a person's life, as well as improving the person's mind and inner well-being. Moreover, it affects the next lives to come, as well as the destination a person is reborn. The opposite of merit is demerit (pāpa), and it is believed that merit is able to weaken demerit. Indeed, merit has even been connected to the path to Nirvana itself, but many scholars say that this refers only to some types of merit. (Full article...)

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.

Lawrence Kohlberg's stages of moral development constitute an adaptation of a psychological theory originally conceived by the Swiss psychologist Jean Piaget. Kohlberg began work on this topic as a psychology graduate student at the University of Chicago in 1958 and expanded upon the theory throughout his life.

The theory holds that moral reasoning, a necessary (but not sufficient) condition for ethical behavior, has six developmental stages, each more adequate at responding to moral dilemmas than its predecessor. Kohlberg followed the development of moral judgment far beyond the ages studied earlier by Piaget, who also claimed that logic and morality develop through constructive stages. Expanding on Piaget's work, Kohlberg determined that the process of moral development was principally concerned with justice and that it continued throughout the individual's life, a notion that led to dialogue on the philosophical implications of such research.

Wave functions of the electron in a hydrogen atom at different energy levels. Quantum mechanics cannot predict the exact location of a particle in space, only the probability of finding it at different locations. The brighter areas represent a higher probability of finding the electron.

Quantum mechanics is the fundamental physical theory that describes the behavior of matter and of light; its unusual characteristics typically occur at and below the scale of atoms. It is the foundation of all quantum physics, which includes quantum chemistry, quantum biology, quantum field theory, quantum technology, and quantum information science.

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, however is insufficient for describing them at very small submicroscopic (atomic and subatomic) scales. Classical mechanics can be derived from quantum mechanics as an approximation that is valid at ordinary scales. (Full article...)

This portrait attributed to Francesco Melzi, c. 1515–1518, is the only certain contemporary depiction of Leonardo.

Leonardo di ser Piero da Vinci (15 April 1452 – 2 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he has also become known for his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and palaeontology. Leonardo is widely regarded as a genius who epitomised the Renaissance humanist ideal, and his collective works contributed to the development of European art to an extent rivalled only by that of his younger contemporary Michelangelo.

Born out of wedlock to a successful notary and a lower-class woman in, or near, Vinci, he was educated in Florence by the Italian painter and sculptor Andrea del Verrocchio. He began his career in the city, but then spent much time in the service of Ludovico Sforza in Milan. Later, he worked in Florence and Milan again, as well as briefly in Rome, all while attracting a large following of imitators and students. Upon the invitation of Francis I, he spent his last three years in France, where he died in 1519. Since his death, there has not been a time when his achievements, diverse interests, personal life, and empirical thinking have failed to incite interest and admiration, making him a frequent namesake and subject in culture.

Batman: Anarky is a 1999 trade paperback published by the comic book publishing company 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. Literary references are also utilized throughout the collected stories to stress the philosophical foundations of the character. The collection also tracks the character's evolution from a petty, street-crime fighting vigilante, to a competent freedom fighter in opposition to powerful forces of evil. (Full article...)

The argument from morality is an argument for the existence of God. Arguments from morality tend to be based on moral normativity or moral order. Arguments from moral normativity observe some aspect of morality and argue that God is the best or only explanation for this, concluding that God must exist. Arguments from moral order are based on the asserted need for moral order to exist in the universe. They claim that, for this moral order to exist, God must exist to support it. The argument from morality is noteworthy in that one cannot evaluate the soundness of the argument without attending to almost every important philosophical issue in meta-ethics.

German philosopher Immanuel Kant devised an argument from morality based on practical reason. Kant argued that the goal of humanity is to achieve perfect happiness and virtue (the summum bonum) and believed that an afterlife must be assumed to exist in order for this to be possible, and that God must be assumed to exist to provide this. Rather than aiming to prove the existence of God, however, Kant was simply attempting to demonstrate that all moral thought requires the assumption that God exists, and therefore that we are entitled to make such an assumption only as a regulative principle rather than a constitutive principle (meaning that such a principle can guide our actions, but it does not provide knowledge). In his book Mere Christianity, C. S. Lewis argued that "conscience reveals to us a moral law whose source cannot be found in the natural world, thus pointing to a supernatural Lawgiver." Lewis argued that accepting the validity of human reason as a given must include accepting the validity of practical reason, which could not be valid without reference to a higher cosmic moral order which could not exist without a God to create and/or establish it. A related argument is from conscience; John Henry Newman argued that the conscience supports the claim that objective moral truths exist because it drives people to act morally even when it is not in their own interest. Newman argued that, because the conscience suggests the existence of objective moral truths, God must exist to give authority to these truths. (Full article...)

Saint Irenaeus, the second-century philosopher and theologian who inspired the development of the Irenaean theodicy.

The Irenaean theodicy is a Christian theodicy (a response to the problem of evil). It defends the probability of an omnipotent and omnibenevolent (all-powerful and perfectly loving) God in the face of evidence of evil in the world. Numerous variations of theodicy have been proposed which all maintain that, while evil exists, God is either not responsible for creating evil, or he is not guilty for creating evil. Typically, the Irenaean theodicy asserts that the world is the best of all possible worlds because it allows humans to fully develop. Most versions of the Irenaean theodicy propose that creation is incomplete, as humans are not yet fully developed, and experiencing evil and suffering is necessary for such development.

The second-century Church Father, theologian and philosopher Irenaeus, after whom the theodicy is named, proposed a two-stage creation process in which humans require free will and the experience of evil to develop. Another early Christian theologian, Origen, presented a response to the problem of evil which cast the world as a schoolroom or hospital for the soul; theologian Mark Scott has argued that Origen, rather than Irenaeus, ought to be considered the father of this kind of theodicy. The theologian Friedrich Schleiermacher argued in the nineteenth century that God must necessarily create flawlessly, so this world must be the best possible world because it allows God's purposes to be naturally fulfilled. In 1966 the philosopher John Hick discussed the similarities of the preceding theodicies, calling them all "Irenaean". He supported the view that creation is incomplete and argued that the world is best placed for the full moral development of humans, as it presents genuine moral choices. The philosopher Richard Swinburne proposed that, to make a free moral choice, humans must have experience of the consequences of their own actions and that natural evil must exist to provide such choices.

J. R. R. Tolkien's bestselling fantasy novel The Lord of the Rings had an initial mixed literary reception. Despite some enthusiastic early reviews from supporters such as W. H. Auden, Iris Murdoch, and C. S. Lewis, scholars noted a measure of literary hostility to Tolkien, which continued until the start of the 21st century. From 1982, Tolkien scholars such as Tom Shippey and Verlyn Flieger began to roll back the hostility, defending Tolkien, rebutting the critics' attacks and analysing what they saw as good qualities in Tolkien's writing.

From 2003, scholars such as Brian Rosebury began to consider why Tolkien had attracted such hostility. Rosebury stated that Tolkien avoided calling The Lord of the Rings a novel, and that in Shippey's view Tolkien had been aiming to create a medieval-style heroic romance, despite modern scepticism about that literary mode. In 2014, Patrick Curry analysed the reasons for the hostility, finding it both visceral and full of evident mistakes, and suggesting that the issue was that the critics felt that Tolkien threatened their dominant ideology, modernism.

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?
