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.
Born and raised in Albany, New York, Hand majored in philosophy at Harvard College and graduated with honors from Harvard Law School. After a relatively undistinguished career as a lawyer in Albany and New York City, he was appointed at the age of 37 as a Manhattan federal district judge in 1909. The profession suited his detached and open-minded temperament, and his decisions soon won him a reputation for craftsmanship and authority. Between 1909 and 1914, under the influence of Herbert Croly's social theories, Hand supported New Nationalism. He ran unsuccessfully as the Progressive Party's candidate for chief judge of the New York Court of Appeals in 1913, but withdrew from active politics shortly afterwards. In 1924, President Calvin Coolidge elevated Hand to the Court of Appeals for the Second Circuit, which he went on to lead as the senior circuit judge (later retitled chief judge) from 1939 until his semi-retirement in 1951. Scholars have recognized the Second Circuit under Hand as one of the finest appeals courts in American history. Friends and admirers often lobbied for Hand's promotion to the Supreme Court, but circumstances and his political past conspired against his appointment. (Full article...)

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...)

Anekāntavāda (Sanskrit: अनेकान्तवाद, "many-sidedness") is the Jain doctrine about metaphysical truths that emerged in ancient India. It states that the ultimate truth and reality is complex and has multiple aspects.
According to Jainism, no single, specific statement can describe the nature of existence and the absolute truth. This knowledge (Kevala Jnana), it adds, is comprehended only by the Arihants. Other beings and their statements about absolute truth are incomplete, and at best a partial truth. All knowledge claims, according to the anekāntavāda doctrine must be qualified in many ways, including being affirmed and denied. Anekāntavāda is a fundamental doctrine of Jainism. (Full article...)
Ion Heliade Rădulescu or Ion Heliade (also known as Eliade or Eliade Rădulescu; Romanian pronunciation:[ˈi.onheliˈaderəduˈlesku]; January 6, 1802 – April 27, 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 Italianneologisms 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.

Anarky is a character appearing in American comic books published by DC Comics. Co-created by Alan Grant and Norm Breyfogle, he first appeared in Detective Comics #608 (November 1989), as an adversary of Batman. Anarky is introduced as Lonnie Machin, a child prodigy with knowledge of radical philosophy and driven to overthrow governments to improve social conditions. Stories revolving around Anarky often focus on political and philosophical themes. The character, who is named after the philosophy of anarchism, primarily espouses anti-statism and attacks capitalism; however, multiple social issues have been addressed through the character, including environmentalism, antimilitarism, economic inequality, and political corruption. Inspired by multiple sources, early stories featuring the character often included homages to political and philosophical texts, and referenced anarchist philosophers and theorists. The inspiration for the creation of the character and its early development was based in Grant's personal interest in anti-authoritarian philosophy and politics. However, when Grant himself transitioned to the philosophy of Neo-Tech developed by Frank R. Wallace, he shifted the focus of Anarky from a vehicle for social anarchism and then libertarian socialism, with an emphasis on wealth redistribution and critique of Capitalism, to themes of individualism and personal reflexions on the nature of consciousness.
Originally intended to only be used in the debut story in which he appeared, Grant decided to continue using Anarky as a sporadically recurring character throughout the early 1990s, following positive reception by readers and Dennis O'Neil. The character experienced a brief surge in media exposure during the late 1990s when Breyfogle convinced Grant to produce a limited series based on the character. The 1997 spin-off series, Anarky, was received with positive reviews and sales, and later declared by Grant to be among his "career highlights". Batman: Anarky, a trade paperback collection of stories featuring the character, soon followed. This popular acclaim culminated, however, in a financially and critically unsuccessful ongoing solo series. The 1999 Anarky series, for which even Grant has expressed his distaste, was quickly canceled after eight issues. (Full article...)

In political philosophy, a throffer is a proposal (also called an intervention) that mixes an offer with a threat which will be carried out if the offer is not accepted. The term was first used in print by political philosopher Hillel Steiner; while other writers followed, it has not been universally adopted and it is sometimes considered synonymous with carrot and stick. Though the threatening aspect of a throffer need not be obvious, or even articulated at all, an overt example is: "Kill this man and receive £100; fail to kill him and I'll kill you."
Steiner differentiated offers, threats and throffers based on the preferability of compliance and noncompliance for the subject when compared to the normal course of events that would have come about were no intervention made. Steiner's account was criticised by philosopher Robert Stevens, who instead suggested that what was important in differentiating the kinds of intervention was whether performing or not performing the requested action was more or less preferable than it would have been were no intervention made. Throffers form part of the wider moral and political considerations of coercion, and form part of the question of the possibility of coercive offers. Contrary to received wisdom that only threats can be coercive, throffers lacking explicit threats have been cited as an example of coercive offers, while some writers argue that offers, threats and throffers may all be coercive if certain conditions are met. For others, by contrast, if a throffer is coercive, it is explicitly the threat aspect that makes it so, and not all throffers can be considered coercive. (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...)
Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. (Full article...)

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...)

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.
Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. After completing graduate work at the Friedrich Wilhelm University in Berlin and Harvard University, where he was its first African American to earn a doctorate, 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 chances for advanced education to develop its leadership.

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.

Teleology in biology is the use of the language of goal-directedness in accounts of evolutionaryadaptation, which some biologists and philosophers of science find problematic. The term teleonomy has also been proposed. Before Darwin, organisms were seen as existing because God had designed and created them; their features such as eyes were taken by natural theology to have been made to enable them to carry out their functions, such as seeing. Evolutionary biologists often use similar teleological formulations that invoke purpose, but these imply natural selection rather than actual goals, whether conscious or not. Some biologists and religious thinkers held that evolution itself was somehow goal-directed (orthogenesis), and in vitalist versions, driven by a purposeful life force. With evolution working by natural selection acting on inherited variation, the use of teleology in biology has attracted criticism, and attempts have been made to teach students to avoid teleological language.
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 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.
Second-century 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. 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, 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. British 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.

Gregory lacked the administrative ability of his brother Basil or the contemporary influence of Gregory of Nazianzus, but he was an erudite Christian theologian who made significant contributions to the doctrine of the Trinity and the Nicene Creed. Gregory's philosophical writings were influenced by Origen. Since the mid-twentieth century, there has been a significant increase in interest in Gregory's works from the academic community, particularly involving universal salvation, which has resulted in challenges to many traditional interpretations of his theology.

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.

Abū al-ʿAlāʾ al-Maʿarrī (Arabic: أبو العلاء المعري, full name أبو العلاء أحمد بن عبد الله بن سليمان التنوخي المعريAbū al-ʿAlāʾ Aḥmad ibn ʿAbd Allāh ibn Sulaymān al-Tanūkhī al-Maʿarrī, also known under his Latin name Abulola Moarrensis; December 973 – May 1057) was a philosopher, poet, and writer from Ma'arrat al-Nu'man, Syria. Because of his controversially irreligious worldview, he is known as one of the "foremost atheists" of his time according to Nasser Rabbat.
Born in the city of al-Ma'arra (present-day Ma'arrat al-Nu'man, Syria) during the later Abbasid era, he became blind at a young age from smallpox but nonetheless studied in nearby Aleppo, then in Tripoli and Antioch. Producing popular poems in Baghdad, he refused to sell his texts. In 1010, he returned to Syria after his mother began declining in health, and continued writing which gained him local respect.

The historiography of the Crusades is the study of history-writing and the written history, especially as an academic discipline, regarding the military expeditions initially undertaken by European Christians in the 11th, 12th, or 13thcenturies to the Holy Land. This scope was later extended to include other campaigns initiated, supported, and sometimes directed by the Roman Catholic Church. The subject has involved competing and evolving interpretations since the capture of Jerusalem in 1099 until the present day. The religious idealism, use of martial force and pragmatic compromises made by those involved in crusading were controversial, both at the time and subsequently. Crusading was integral to Western European culture, with the ideas that shaped behaviour in the Late Middle Ages retaining currency beyond the 15thcentury in attitude rather than action.
From the 17thcentury historians began rejecting the religious motivations applied to crusading and instead examined the secular. The building of nation states led to the application of interpretations in support of this and fundamentally discrete from the religious sphere. This presented a challenge in reconciling the idealistic and the materialistic motives of the protagonists. The internationalism of crusading remained an obstacle to those historians wishing to project both the idea of crusading and the Crusades themselves as nationalistic precedents. Enlightenment thinkers considered the crusaders culturally inferior to themselves and Protestants considered them morally so. (Full article...)

Little is known about Aristotle's life. He was born in the city of Stagira in northern Greece during the Classical period. His father, Nicomachus, died when Aristotle was a child, and he was brought up by a guardian. At 17 or 18, he joined Plato's Academy in Athens and remained there until the age of 37 (c. 347 BC). Shortly after Plato died, Aristotle left Athens and, at the request of Philip II of Macedon, tutored his son Alexander the Great beginning in 343 BC. He established a library in the Lyceum, which helped him to produce many of his hundreds of books on papyrusscrolls. (Full article...)

Eureka (1848) is a lengthy non-fiction work by American author Edgar Allan Poe (1809–1849) which he subtitled "A Prose Poem", though it has also been subtitled "An Essay on the Material and Spiritual Universe". Adapted from a lecture he had presented, Eureka describes Poe's intuitive conception of the nature of the universe, with no antecedent scientific work done to reach his conclusions. He also discusses man's relationship with God, whom he compares to an author. Eureka is dedicated to the German naturalist and explorer Alexander von Humboldt (1769–1859).
Though Eureka is generally considered a literary work, some of Poe's ideas anticipate 20th-century scientific discoveries and theories. Analysis of Eureka's scientific content shows congruities with modern cosmology, stemming from Poe's assumption of an evolving Universe. (Full article...)

Consciousness, at its simplest, is awareness of internal and external existence. However, its nature has led to millennia of analyses, explanations and debate by philosophers, theologians, and all of science. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the mind, and at other times, an aspect of mind. In the past, it was one's "inner life", the world of introspection, of private thought, imagination and volition. Today, it often includes any kind of cognition, experience, feeling or perception. It may be awareness, awareness of awareness, or self-awareness either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked.
Reich's work on character contributed to the development of Anna Freud's The Ego and the Mechanisms of Defence (1936), and his idea of muscular armour—the expression of the personality in the way the body moves—shaped innovations such as body psychotherapy, Gestalt therapy, bioenergetic analysis and primal therapy. His writing influenced generations of intellectuals; he coined the phrase "the sexual revolution" and according to one historian acted as its midwife. During the 1968 student uprisings in Paris and Berlin, students scrawled his name on walls and threw copies of The Mass Psychology of Fascism at police. (Full article...)
The essay posits that monotheism and the Enlightenment are based on "monomythical thinking", meaning that they only allow one story. It also posits that the separation of powers and the individual have their origin in polytheism, and argues that people should embrace what Marquard calls "enlightened polymythical thinking"—the recognition of several stories in the modern world. Marquard was a professor of philosophy and proponent of scepticism and pluralism. He belonged to a part of German philosophy that viewed the issues of modernity through political theology, which associates modern political concepts with theological concepts. Some of the points in the essay have precursors in the writings of Max Weber, Erik Peterson and Friedrich Nietzsche. (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?
