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.

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...)
In his early life, Maximus was a civil servant, and an aide to the Byzantine EmperorHeraclius. 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.

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.

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...)
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).

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...)
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...)

Political Animals and Animal Politics is a 2014 edited collection published by Palgrave Macmillan and edited by the greenpolitical theoristsMarcel Wissenburg and David Schlosberg. The work addresses the emergence of academic animal ethics informed by political philosophy as opposed to moral philosophy. It was the first edited collection to be published on the topic, and the first book-length attempt to explore the breadth and boundaries of the literature. As well as a substantial introduction by the editors, it features ten sole-authored chapters split over three parts, respectively concerning institutional change for animals, the relationship between animal ethics and ecologism, and real-world laws made for the benefit of animals. The book's contributors were Wissenburg, Schlosberg, Manuel Arias-Maldonado, Chad Flanders, Christie Smith, Clemens Driessen, Simon Otjes, Kurtis Boyer, Per-Anders Svärd, and Mihnea Tanasescu. The focus of their individual chapters varies, but recurring features include discussions of human exceptionalism, exploration of ways that animal issues are or could be present in political discourse, and reflections on the relationship between theory and practice in politics.
The Nazi regime considered the elimination of all manifestations of homosexuality in Germany one of its goals. Men were often arrested after denunciation, police raids, and through information uncovered during interrogations of other homosexuals. Those arrested were presumed guilty, and subjected to harsh interrogation and torture to elicit a confession. Between 1933 and 1945, an estimated 100,000 men were arrested as homosexuals; around 50,000 of these were sentenced by civilian courts, 6,400 to 7,000 by military courts [de], and an unknown number by special courts. Most of these men served time in regular prisons, and between 5,000 and 6,000 were imprisoned in concentration camps. The death rate of these prisoners has been estimated at 60 percent, a higher rate than those of other prisoner groups. A smaller number of men were sentenced to death or killed at Nazi euthanasia centres. Nazi Germany's persecution of homosexuals is considered to be the most severe episode in a long history of discrimination and violence targeting sexual minorities. (Full article...)

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.
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.
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...)

Zhuangzi (莊子, 庄子, Zhuāng Zǐ, Chuang Tzŭ, Chuang Tsu, Zhuang Tze, or Chuang Tse) was a skeptical and mysticalChinese philosopher who lived around the 4th century BCE during the Warring States period. The Taoist text Zhuangzi is speculated to be partly authored by him and is the source of many anecdotes and idioms. He argued that life and knowledge are limited, and denied the need for government. His points on the limitations of language and the importance of being spontaneous were strongly influential in the development of Chinese Buddhism, especially Chan (Zen).
Described by his mentor and colleague Bertrand Russell as "the most perfect example I have ever known of genius as traditionally conceived, passionate, profound, intense, and dominating," Wittgenstein is considered by many to be the greatest philosopher of the 20th century. Instrumental in inspiring two of the century's principal philosophical movements, logical positivism and ordinary language philosophy, he is considered one of the most important figures in analytic philosophy. According to an end of the century poll, professional philosophers rank both his Tractatus Logico-Philosophicus (1921) and Philosophical Investigations (1953) among the top five most important books in twentieth-century philosophy, the latter standing out as "the one crossover masterpiece in twentieth-century philosophy, appealing across diverse specializations and philosophical orientations." Wittgenstein's influence has been felt in nearly every field of the humanities and social sciences, yet there are widely diverging interpretations of his thought.
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.

The second circle of hell is depicted in Dante Alighieri's 14th-century poem Inferno, the first part of the 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 second circle represents the sin of lust, where the lustful are punished by being buffeted within an endless tempest.
The circle of lust introduces Dante's depiction of King Minos, the judge of hell; this portrayal derives from the role of Minos in the Greek underworld in the works of Virgil and Homer. Dante also depicts a number of historical and mythological figures within the second circle, although chief among these are Francesca da Rimini and Paolo Malatesta, murdered lovers whose story was well-known in Dante's time. Malatesta and da Rimini have since been the focus of academic interpretation and the inspiration for other works of art. (Full article...)

Crime and Punishment (pre-reform Russian: Преступленіе и наказаніе; post-reform Russian: Преступление и наказание, tr.Prestupleniye i nakazaniye, IPA:[prʲɪstʊˈplʲenʲɪjeɪnəkɐˈzanʲɪje]) is a novel by the Russian author Fyodor Dostoevsky. It was first published in the literary journal The Russian Messenger in twelve monthly installments during 1866. It was later published in a single volume. It is the second of Dostoevsky's full-length novels following his return from ten years of exile in Siberia. Crime and Punishment is considered the first great novel of his mature period of writing and is often cited as one of the greatest works of world literature.
Crime and Punishment follows the mental anguish and moral dilemmas of Rodion Raskolnikov, an impoverished ex-student in Saint Petersburg who plans to kill an unscrupulous pawnbroker, an old woman who stores money and valuable objects in her flat. He theorises that with the money he could liberate himself from poverty and go on to perform great deeds, and seeks to convince himself that certain crimes are justifiable if they are committed in order to remove obstacles to the higher goals of 'extraordinary' men. Once the deed is done, however, he finds himself wracked with confusion, paranoia, and disgust. His theoretical justifications lose all their power as he struggles with guilt and horror and is confronted with both internal and external consequences of his deed. (Full article...)
The anecdotes and narratives of Krishna's life are generally titled as Krishna Līlā. He is a central figure in the Mahabharata, the Bhagavata Purana, the Brahma Vaivarta Purana, and the Bhagavad Gita, and is mentioned in many Hindu philosophical, theological, and mythological texts. They portray him in various perspectives: as a god-child, a prankster, a model lover, a divine hero, and the universal supreme being. His iconography reflects these legends and shows him in different stages of his life, such as an infant eating butter, a young boy playing a flute, a young boy with Radha or surrounded by female devotees, or a friendly charioteer giving counsel to Arjuna.

Hypatia (born c. 350–370; died 415 AD) was a Neoplatonist philosopher, astronomer, and mathematician who lived in Alexandria, Egypt, then part of the Eastern Roman Empire. She was a prominent thinker in Alexandria where she taught philosophy and astronomy. Although preceded by Pandrosion, another Alexandrian female mathematician, she is the first female mathematician whose life is reasonably well recorded. Hypatia was renowned in her own lifetime as a great teacher and a wise counselor. She wrote a commentary on Diophantus's thirteen-volume Arithmetica, which may survive in part, having been interpolated into Diophantus's original text, and another commentary on Apollonius of Perga's treatise on conic sections, which has not survived. Many modern scholars also believe that Hypatia may have edited the surviving text of Ptolemy's Almagest, based on the title of her father Theon's commentary on Book III of the Almagest.
Hypatia constructed astrolabes and hydrometers, but did not invent either of these, which were both in use long before she was born. She was tolerant toward Christians and taught many Christian students, including Synesius, the future bishop of Ptolemais. Ancient sources record that Hypatia was widely beloved by pagans and Christians alike and that she established great influence with the political elite in Alexandria. Toward the end of her life, Hypatia advised Orestes, the Roman prefect of Alexandria, who was in the midst of a political feud with Cyril, the bishop of Alexandria. Rumors spread accusing her of preventing Orestes from reconciling with Cyril and, in March 415 AD, she was murdered by a mob of Christians led by a lector named Peter. (Full article...)

Rose Street as seen in an original sketch of 1851
The Rose Street Club (sometimes the International Rose Street Club and earlier the Local Rights Association for Rental and Sanitary Reform) was a far-left, anarchist organisation based in what is now Manette Street, London. Originally centred around London's German community, and acting as a meeting point for new immigrants, it became one of the leading radical clubs of Victorian London in the late-nineteenth century. Although its roots went back to the 1840s, it was properly formed in 1877 by members of a German émigré workers' education group, which soon became frequented by London radicals, and within a few years had led to the formation of similar clubs, sometimes in support and sometimes in rivalry. The Rose Street Club provided a platform for the radical speakers and agitators of the day and produced its own paper, Freiheit—which was distributed over Europe, and especially Germany—and pamphlets for other groups and individuals. Although radical, the club initially focused as much on providing a social service to its members as on activism. With the arrival of the anarchist Johann Most in London in the early 1880s, and his increasing influence within the club, it became increasingly aligned with anarchism. (Full article...)

Feminism is a range of socio-political movements and ideologies that aim to define and establish the political, economic, personal, and social equality of the sexes. Feminism holds the position that societies prioritize the male point of view and that women are treated unjustly in these societies. Efforts to change this include fighting against gender stereotypes and improving educational, professional, and interpersonal opportunities and outcomes for women.
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.

The first seventy-seven of these essays were published serially in the Independent Journal, the New York Packet, and The Daily Advertiser between October 1787 and April 1788. A compilation of these 77 essays and eight others were published in two volumes as The Federalist: A Collection of Essays, Written in Favour of the New Constitution, as Agreed upon by the Federal Convention, September 17, 1787, by publishing firm J. & A. McLean in March and May 1788. The last eight papers (Nos. 78–85) were republished in the New York newspapers between June 14 and August 16, 1788. (Full article...)

According to Sarah Shaw, in Theravada this systematic work is "the principal text on the subject of meditation." The interpretations provided by Buddhaghosa have generally constituted the orthodox understanding of Theravada scriptures since at least the 12th century CE. (Full article...)

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritabletraits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not.
Variation of traits, both genotypic and phenotypic, exists within all populations of organisms. However, some traits are more likely to facilitate survival and reproductive success. Thus, these traits are passed onto the next generation. These traits can also become more common within a population if the environment that favours these traits remain fixed. If new traits become more favored due to changes in a specific niche, microevolution occurs. If new traits become more favored due to changes in the broader environment, macroevolution occurs. Sometimes, new species can arise especially if these new traits are radically different from the traits possessed by their predecessors. (Full article...)

Karma is the basic principle within an overarching psycho-cosmology in Jainism. Human moral actions form the basis of the transmigration of the soul (jīva). The soul is constrained to a cycle of rebirth, trapped within the temporal world (saṃsāra), until it finally achieves liberation (mokṣa). Liberation is achieved by following a path of purification.
Jains believe that karma is a physical substance that is everywhere in the universe. Karma particles are attracted to the soul by the actions of that soul. Karma particles are attracted when we do, think, or say things, when we kill something, when we lie, when we steal and so on. Karma not only encompasses the causality of transmigration, but is also conceived of as an extremely subtle matter, which infiltrates the soul—obscuring its natural, transparent and pure qualities. Karma is thought of as a kind of pollution, that taints the soul with various colours (leśyā). Based on its karma, a soul undergoes transmigration and reincarnates in various states of existence—like heavens or hells, or as humans or animals. (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?
