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.

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...)

Goldman, c. 1911
Emma Goldman (June 27, 1869 – May 14, 1940) was a Lithuanian-born anarchistrevolutionary, political activist, and writer. She played a pivotal role in the development of anarchist political philosophy in North America and Europe in the first half of the 20th century.
Born in Kaunas, Lithuania (then within the Russian Empire), to an OrthodoxLithuanian Jewish family, Goldman emigrated to the United States in 1885. Attracted to anarchism after the Chicago Haymarket affair, Goldman became a writer and a renowned lecturer on anarchist philosophy, women's rights, and social issues, attracting crowds of thousands. She and anarchist writer Alexander Berkman, her lover and lifelong friend, planned to assassinate industrialist and financier Henry Clay Frick as an act of propaganda of the deed. Frick survived the attempt on his life in 1892, and Berkman was sentenced to 22 years in prison. Goldman was imprisoned several times in the years that followed, for "inciting to riot" and illegally distributing information about birth control. In 1906, Goldman founded the anarchist journal Mother Earth. (Full article...)

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.

A stamp of Zhang Heng issued by China Post in 1955
Zhang Heng began his career as a minor civil servant in Nanyang. Eventually, he became Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court. His uncompromising stance on historical and calendrical issues led to his becoming a controversial figure, preventing him from rising to the status of Grand Historian. His political rivalry with the palace eunuchs during the reign of Emperor Shun (r. 125–144) led to his decision to retire from the central court to serve as an administrator of Hejian Kingdom in present-day Hebei. Zhang returned home to Nanyang for a short time, before being recalled to serve in the capital once more in 138. He died there a year later, in 139. (Full article...)
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...)

The Augustinian theodicy, named for the 4th- and 5th-century theologian and philosopher Augustine of Hippo, is a type of Christiantheodicy that developed in response to the evidential problem of evil. As such, it attempts to explain the probability of an omnipotent (all-powerful) and omnibenevolent (all-loving) God amid evidence of evil in the world. A number of variations of this kind of theodicy have been proposed throughout history; their similarities were first described by the 20th-century philosopher John Hick, who classified them as "Augustinian". They typically assert that God is perfectly (ideally) good, that he created the world out of nothing, and that evil is the result of humanity's original sin. The entry of evil into the world is generally explained as consequence of original sin and its continued presence due to humans' misuse of free will and concupiscence. God's goodness and benevolence, according to the Augustinian theodicy, remain perfect and without responsibility for evil or suffering.
Augustine of Hippo was the first to develop the theodicy. He rejected the idea that evil exists in itself, instead regarding it as a corruption of goodness, caused by humanity's abuse of free will. Augustine believed in the existence of a physical Hell as a punishment for sin, but argued that those who choose to accept the salvation of Jesus Christ will go to Heaven. In the 13th century, Thomas Aquinas – influenced by Augustine – proposed a similar theodicy based on the view that God is goodness and that there can be no evil in him. He believed that the existence of goodness allows evil to exist, through the fault of humans. Augustine also influenced John Calvin, who supported Augustine's view that evil is the result of free will and argued that sin corrupts humans, requiring God's grace to give moral guidance.

Confirmation bias (also confirmatory bias, myside bias, or congeniality bias) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs. Confirmation bias is insuperable for most people, but they can manage it, for example, by education and training in critical thinking skills.
Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects:
attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence)
belief perseverance (when beliefs persist after the evidence for them is shown to be false)
the irrational primacy effect (a greater reliance on information encountered early in a series)
illusory correlation (when people falsely perceive an association between two events or situations).
1897 illustration of La Peau de chagrin, drawn by Adrien Moreau and published by George Barrie & Son
La Peau de chagrin (French pronunciation:[lapodəʃaɡʁɛ̃], The Skin of Shagreen), known in English as The Magic Skin and The Wild Ass's Skin, is an 1831novel 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...)

Why Marx Was Right is a 2011 non-fiction book by the British academic Terry Eagleton about the 19th-century philosopher Karl Marx and the schools of thought, collectively known as Marxism, that arose from his work. Written for laypeople, Why Marx Was Right outlines ten objections to Marxism that they may hold and aims to refute each one in turn. These include arguments that Marxism is irrelevant owing to changing social classes in the modern world, that it is deterministic and utopian, and that Marxists oppose all reforms and believe in an authoritarian state.
In his counterarguments, Eagleton explains how class struggle is central to Marxism, and that history is seen as a progression of modes of production, like feudalism and capitalism, involving the materials, technology and social relations required to produce goods and services within the society. Under a capitalist economy, the working class, known as the proletariat, are those lacking significant autonomy over their labour conditions, and have no control over the means of production. Eagleton describes how revolutions could lead to a new mode of production—socialism—in which the working class have control, and an eventual communist society could make the state obsolete. He explores the failures of the Soviet Union and other Marxist–Leninist countries. (Full article...)

Cover of the first edition
The Fountainhead is a 1943 novel by Russian-American author Ayn Rand, her first major literary success. The novel's protagonist, Howard Roark, is an intransigent young architect who battles against conventional standards and refuses to compromise with an architectural establishment unwilling to accept innovation. Roark embodies what Rand believed to be the ideal man, and his struggle reflects Rand's belief that individualism is superior to collectivism.
Roark is opposed by what he calls "second-handers", who value conformity over independence and integrity. These include Roark's former classmate, Peter Keating, who succeeds by following popular styles but turns to Roark for help with design problems. Ellsworth Toohey, a socialistarchitecture critic who uses his influence to promote his political and social agenda, tries to destroy Roark's career. Tabloid newspaper publisher Gail Wynand seeks to shape popular opinion; he befriends Roark, then betrays him when public opinion turns in a direction he cannot control. The novel's most controversial character is Roark's lover, Dominique Francon. She believes that non-conformity has no chance of winning, so she alternates between helping Roark and working to undermine him. (Full article...)
H. L. A. Hart (Herbert Lionel Adolphus Hart) (1907-1992) is widely regarded as the most important English-speakinglegal philosopher of the twentieth century. He was Professor of Jurisprudence at Oxford University and is the author of The Concept of Law. Hart developed a sophisticated theory of legal positivism within the framework of analytic philosophy: He maintained that there is no necessary connection between law and morality; that for a legal system to be efficient there must be secondary legal rules to alter any primary legal rules of obligation; and that rules must be socially acceptable and recognized for them to be valid. Hart also made major contributions to political philosophy.
A paradox is a true statement or group of statements that leads to a contradiction or a situation which defies intuition. The term is also used for an apparent contradiction that actually expresses a non-dual truth (cf.kōan, Catuskoti). Typically, the statements in question do not really imply the contradiction, the puzzling result is not really a contradiction, or the premises themselves are not all really true or cannot all be true together. The word paradox is often used interchangeably with contradiction. It is also used to describe situations that are ironic.
Everything that is known about Lucian's life comes from his own writings, which are often difficult to interpret because of his extensive use of sarcasm. According to his oration The Dream, he was the son of a lower middle class family from the city of Samosata along the banks of the Euphrates in the remote Roman province of Syria. As a young man, he was apprenticed to his uncle to become a sculptor, but, after a failed attempt at sculpting, he ran away to pursue an education in Ionia. He may have become a travelling lecturer and visited universities throughout the Roman Empire. After acquiring fame and wealth through his teaching, Lucian finally settled down in Athens for a decade, during which he wrote most of his extant works. In his fifties, he may have been appointed as a highly paid government official in Egypt, after which point he disappears from the historical record. (Full article...)
Due to the wide range of accounting services and recent corporate collapses, attention has been drawn to ethical standards accepted within the accounting profession. These collapses have resulted in a widespread disregard for the reputation of the accounting profession. To combat the criticism and prevent fraudulent accounting, various accounting organizations and governments have developed regulations and remedies for improved ethics among the accounting profession.

Marcellina was an early ChristianCarpocratian 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...)

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...)
Sun Tzu mastered the military science of ancient China and created the military doctrine of asymmetrical warfare. According to it, an attack on the enemy should begin only after the enemy has no opportunity to either defend or counterattack. It was used in the wars in the era of the Warring States in ancient China (about 475–221 BC). It's not the direct interpretation of the modern asymmetric military strategy. The ancient warriors used to call it the Victorious Methods of Warfare – Sheng Er Zhan Zhi, but it has the same meaning as the modern asymmetrical military strategy. The ancient professional warriors used it in individual combats against the enemies in the wars. As a result, a variety of armed and unarmed combat combinations have been created for various combat situations as the individual battle plans. Those combat combinations had specific names, descriptions and classifications. (Full article...)

Golos Truda (Russian: Голос Труда, lit. 'The Voice of Labour') was a Russian-languageanarchist 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 Trudacollective was finally expunged by the Stalinist regime in 1929.

During the Great Depression of the 1930s, Keynes spearheaded a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as long as workers were flexible in their wage demands. He argued that aggregate demand (total spending in the economy) determined the overall level of economic activity, and that inadequate aggregate demand could lead to prolonged periods of high unemployment, and since wages and labour costs are rigid downwards the economy will not automatically rebound to full employment. Keynes advocated the use of fiscal and monetary policies to mitigate the adverse effects of economic recessions and depressions. He detailed these ideas in his magnum opus, The General Theory of Employment, Interest and Money, published in early 1936. By the late 1930s, leading Western economies had begun adopting Keynes's policy recommendations. Almost all capitalist governments had done so by the end of the two decades following Keynes's death in 1946. As a leader of the British delegation, Keynes participated in the design of the international economic institutions established after the end of World War II but was overruled by the American delegation on several aspects.

Generally seen as a pioneering work of zoology, Aristotle frames his text by explaining that he is investigating the what (the existing facts about animals) prior to establishing the why (the causes of these characteristics). The book is thus an attempt to apply philosophy to part of the natural world. Throughout the work, Aristotle seeks to identify differences, both between individuals and between groups. A group is established when it is seen that all members have the same set of distinguishing features; for example, that all birds have feathers, wings, and beaks. This relationship between the birds and their features is recognized as a universal. (Full article...)

Cries and Whispers (Swedish: Viskningar och rop, lit. 'Whispers and Cries') is a 1972 Swedish period drama film written and directed by Ingmar Bergman and starring Harriet Andersson, Kari Sylwan, Ingrid Thulin and Liv Ullmann. The film, set in a mansion at the end of the 19th century, is about three sisters and a servant who struggle with the terminal cancer of one of the sisters (Andersson). The servant (Sylwan) is close to her, while the other two sisters (Ullmann and Thulin) confront their emotional distance from each other.
Inspired by Bergman's mother, Karin Åkerblom, and his vision of four women in a red room, Cries and Whispers was filmed at Taxinge-Näsby Castle in 1971. Its themes include faith, the female psyche and the search for meaning in suffering, and academics have found Biblical allusions. Unlike previous Bergman films, it uses saturated colour, crimson in particular. (Full article...)

In pragmatics, a subdiscipline of linguistics, an implicature is something the speaker suggests or implies with an utterance, even though it is not literally expressed. Implicatures can aid in communicating more efficiently than by explicitly saying everything we want to communicate. The philosopher H. P. Grice coined the term in 1975. Grice distinguished conversational implicatures, which arise because speakers are expected to respect general rules of conversation, and conventional ones, which are tied to certain words such as "but" or "therefore". Take for example the following exchange:
: A (to passerby): I am out of gas. : B: There is a gas station 'round the corner. (Full article...)

Sir William Blackstone (10 July 1723 – 14 February 1780) was an English jurist, justice and Tory politician most noted for his Commentaries on the Laws of England, which became the best-known description of the doctrines of the English common law. Born into a middle-class family in London, Blackstone was educated at Charterhouse School before matriculating at Pembroke College, Oxford, in 1738. After switching to and completing a Bachelor of Civil Law degree, he was made a fellow of All Souls College, Oxford, on 2 November 1743, admitted to Middle Temple, and called to the Bar there in 1746. Following a slow start to his career as a barrister, Blackstone became heavily involved in university administration, becoming accountant, treasurer and bursar on 28 November 1746 and Senior Bursar in 1750. Blackstone is considered responsible for completing the Codrington Library and Warton Building, and simplifying the complex accounting system used by the college. On 3 July 1753 he formally gave up his practice as a barrister and instead embarked on a series of lectures on English law, the first of their kind. These were massively successful, earning him a total of £453 (£89,000 in 2023 terms), and led to the publication of An Analysis of the Laws of England in 1756, which repeatedly sold out and was used to preface his later works.
On 20 October 1759 Blackstone was confirmed as the first Vinerian Professor of English Law, immediately embarking on another series of lectures and publishing a similarly successful second treatise, titled A Discourse on the Study of the Law. With his growing fame, he successfully returned to the bar and maintained a good practice, also securing election as ToryMember of Parliament for the rotten borough of Hindon on 30 March 1761. In November 1765 he published the first of four volumes of Commentaries on the Laws of England, considered his magnum opus; the completed work earned Blackstone £14,000 (£2,459,000 in 2023 terms). After repeated failures, he successfully gained appointment to the judiciary as a justice of the Court of King's Bench on 16 February 1770, leaving to replace Edward Clive as a justice of the Common Pleas on 25 June. He remained in this position until his death, on 14 February 1780. (Full article...)
Romanticism in Scotland was an artistic, literary and intellectual movement that developed between the late eighteenth and the early nineteenth centuries. It was part of the wider European Romantic movement, which was partly a reaction against the Age of Enlightenment, emphasising individual, national and emotional responses, moving beyond Renaissance and Classicist models, particularly into nostalgia for the Middle Ages. The concept of a separate national Scottish Romanticism was first articulated by the critics Ian Duncan and Murray Pittock in the Scottish Romanticism in World Literatures Conference held at UC Berkeley in 2006 and in the latter's Scottish and Irish Romanticism (2008), which argued for a national Romanticism based on the concepts of a distinct national public sphere and differentiated inflection of literary genres; the use of Scots language; the creation of a heroic national history through an Ossianic or Scottian 'taxonomy of glory' and the performance of a distinct national self in diaspora.
In the arts, Romanticism manifested itself in literature and drama in the adoption of the mythical bard Ossian, the exploration of national poetry in the work of Robert Burns and in the historical novels of Walter Scott. Scott also had a major impact on the development of a national Scottish drama. Art was heavily influenced by Ossian and a new view of the Highlands as the location of a wild and dramatic landscape. Scott profoundly affected architecture through his re-building of Abbotsford House in the early nineteenth century, which set off the boom in the Scots Baronial revival. In music, Burns was part of an attempt to produce a canon of Scottish song, which resulted in a cross fertilisation of Scottish and continental classical music, with romantic music becoming dominant in Scotland into the twentieth century.

The third circle of hell is depicted in Dante Alighieri's Inferno, the first part of the 14th-century poem Divine Comedy. Inferno tells the story of Dante's journey through a vision of the Christian hell ordered into nine circles corresponding to classifications of sin; the third circle represents the sin of gluttony, where the souls of the gluttonous are punished in a realm of icy mud.
Within the third circle, Dante encounters a man named Ciacco, with whom he discusses the contemporary strife between the Guelphs and Ghibellines in Florence; the circle is also inhabited by the three-headed hound Cerberus, who torments sinners by rending them apart. (Full article...)

Philosophy ponders the most fundamental questions humankind has been able to ask. These are increasingly numerous and over time they have been arranged into the overlapping branches of the philosophy tree:
Aesthetics: What is art? What is beauty? Is there a standard of taste? Is art meaningful? If so, what does it mean? What is good art? Is art for the purpose of an end, or is "art for art's sake?" What connects us to art? How does art affect us? Is some art unethical? Can art corrupt or elevate societies?
Epistemology: What are the nature and limits of knowledge? What is more fundamental to human existence, knowing (epistemology) or being (ontology)? How do we come to know what we know? What are the limits and scope of knowledge? How can we know that there are other minds (if we can)? How can we know that there is an external world (if we can)? How can we prove our answers? What is a true statement?
Ethics: Is there a difference between ethically right and wrong actions (or values, or institutions)? If so, what is that difference? Which actions are right, and which wrong? Do divine commands make right acts right, or is their rightness based on something else? Are there standards of rightness that are absolute, or are all such standards relative to particular cultures? How should I live? What is happiness?
Logic: What makes a good argument? How can I think critically about complicated arguments? What makes for good thinking? When can I say that something just does not make sense? Where is the origin of logic?
Metaphysics: What sorts of things exist? What is the nature of those things? Do some things exist independently of our perception? What is the nature of space and time? What is the relationship of the mind to the body? What is it to be a person? What is it to be conscious? Do gods exist?
Political philosophy: Are political institutions and their exercise of power justified? What is justice? Is there a 'proper' role and scope of government? Is democracy the best form of governance? Is governance ethically justifiable? Should a state be allowed? Should a state be able to promote the norms and values of a certain moral or religious doctrine? Are states allowed to go to war? Do states have duties against inhabitants of other states?
