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.
Putnam applied equal scrutiny to his own philosophical positions as to those of others, subjecting each position to rigorous analysis until he exposed its flaws. As a result, he acquired a reputation for frequently changing his positions. In philosophy of mind, Putnam argued against the type-identity of mental and physical states based on his hypothesis of the multiple realizability of the mental, and for the concept of functionalism, an influential theory regarding the mind–body problem. In philosophy of language, along with Saul Kripke and others, he developed the causal theory of reference, and formulated an original theory of meaning, introducing the notion of semantic externalism based on a thought experiment called Twin Earth.

Atheism, in the broadest sense, is an absence of belief in the existence of deities. Less broadly, atheism is a rejection of the belief that any deities exist. In an even narrower sense, atheism is specifically the position that there are no deities. Atheism is contrasted with theism, which in its most general form is the belief that at least one deity exists.
Historically, evidence of atheistic viewpoints can be traced back to classical antiquity and early Indian philosophy. In the Western world, atheism declined as Christianity gained prominence. The 16th century and the Age of Enlightenment marked the resurgence of atheistic thought in Europe. Atheism achieved a significant position in the 20th century with legislation protecting freedom of thought. According to 2003 estimates, there are at least 500 million atheists in the world.[needs update] (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.

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.

The problem of religious language considers whether it is possible to talk about God meaningfully if the traditional conceptions of God as being incorporeal, infinite, and timeless, are accepted. Because these traditional conceptions of God make it difficult to describe God, religious language has the potential to be meaningless. Theories of religious language either attempt to demonstrate that such language is meaningless, or attempt to show how religious language can still be meaningful.
Traditionally, religious language has been explained as via negativa, analogy, symbolism, or myth, each of which describes a way of talking about God in human terms. The via negativa is a way of referring to God according to what God is not; analogy uses human qualities as standards against which to compare divine qualities; symbolism is used non-literally to describe otherwise ineffable experiences; and a mythological interpretation of religion attempts to reveal fundamental truths behind religious stories. Alternative explanations of religious language cast it as having political, performative, or imperative functions. (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...)

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.

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...)

The title-page of the 1759 edition published by Cramer in Geneva, which reads, "Candide, or Optimism, translated from the German by Dr. Ralph."
Candide, ou l'Optimisme (/kɒnˈdiːd/kon-DEED, French:[kɑ̃did]ⓘ) is a French satire written by Voltaire, a philosopher of the Age of Enlightenment, first published in 1759. The novella has been widely translated, with English versions titled Candide: or, All for the Best (1759); Candide: or, The Optimist (1762); and Candide: Optimism (1947). It begins with a young man, Candide, who is living a sheltered life in an Edenicparadise and being indoctrinated with Leibnizian optimism by his mentor, Professor Pangloss. The work describes the abrupt cessation of this lifestyle, followed by Candide's slow and painful disillusionment as he witnesses and experiences great hardships in the world. Voltaire concludes Candide with, if not rejecting Leibnizian optimism outright, advocating a deeply practical precept, "we must cultivate our garden", in lieu of the Leibnizian mantra of Pangloss, "all is for the best" in the "best of all possible worlds".
Candide is characterized by its tone as well as by its erratic, fantastical, and fast-moving plot. A picaresque novel with a story similar to that of a more serious coming-of-age narrative (bildungsroman), it parodies many adventure and romance clichés, the struggles of which are caricatured in a tone that is bitter and matter-of-fact. Still, the events discussed are often based on historical happenings, such as the Seven Years' War and the 1755 Lisbon earthquake. As philosophers of Voltaire's day contended with the problem of evil, so does Candide in this short theological novel, albeit more directly and humorously. Voltaire ridicules religion, theologians, governments, armies, philosophies, and philosophers. Through Candide, he assaults Leibniz and his optimism. (Full article...)
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.

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).

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...)

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.

America's 60 Families is a book by American journalist Ferdinand Lundberg published in 1937 by Vanguard Press. It is an argumentative analysis of wealth and class in the United States, and how they are leveraged for purposes of political and economic power, specifically by what the author contends is a "plutocratic circle" composed of a tightly interlinked group of 60 families.
The controversial study has met with mixed reactions since its publication. Though praised by some contemporary and modern reviewers, and once cited in a speech by Harold L. Ickes, it has also been criticized by others and was the subject of a 1938 libel suit by DuPont over factual inaccuracies contained in the text. In 1968 Lundberg published The Rich and the Super-Rich, described by some sources as a sequel to America's 60 Families. (Full article...)

Batman: Anarky is a 1999trade paperback published by DC Comics. The book collects prominent appearances of Anarky, a comic book character created by Alan Grant and Norm Breyfogle. Although all of the collected stories were written by Alan Grant, various artists contributed to individual stories. Dual introductions were written by the creators - both of whom introduce the character and give insight into their role in Anarky's creation and development.
Featured as an antagonist in various Batman comics during the '90s, stories based on the character were highly thematic, political, and philosophical in tone. The majority of the collected stories ("Anarky in Gotham City", "Anarky: Tomorrow Belongs to Us", "Anarky") are influenced by the philosophy of anarchism, while the final story ("Metamorphosis") is influenced by Frank R. Wallace. Although anti-statism is the overarching theme of the collection, other concepts are explored. Anarky's characterization was expanded throughout the stories to present him first as a libertarian socialist and anarchist, and in the final story as a vehicle for explorations into atheism, rationalism, and bicameral mentality. 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...)

Representation of Origen writing, from a manuscript of In numeros homilia XXVII, c. 1160
Origen of Alexandria (c. 185 – c. 253), also known as Origen Adamantius, was an early Christianscholar, ascetic, and theologian who was born and spent the first half of his career in Alexandria. He was a prolific writer who wrote roughly 2,000 treatises in multiple branches of theology, including textual criticism, biblical exegesis and hermeneutics, homiletics, and spirituality. He was one of the most influential and controversial figures in early Christian theology, apologetics, and asceticism. He has been described as "the greatest genius the early church ever produced".
Origen sought martyrdom with his father at a young age but was prevented from turning himself in to the authorities by his mother. When he was eighteen years old, Origen became a catechist at the Catechetical School of Alexandria. He devoted himself to his studies and adopted an ascetic lifestyle. He came into conflict with Demetrius, the bishop of Alexandria, in 231 after he was ordained as a presbyter by his friend Theoclistus, the bishop of Caesarea, while on a journey to Athens through Palestine. Demetrius condemned Origen for insubordination and accused him of having castrated himself and of having taught that even Satan would eventually attain salvation, an accusation which Origen vehemently denied. Origen founded the Christian School of Caesarea, where he taught logic, cosmology, natural history, and theology, and became regarded by the churches of Palestine and Arabia as the ultimate authority on all matters of theology. He was tortured for his faith during the Decian persecution in 250 and died three to four years later from his injuries. (Full article...)

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...)

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...)

The teleological argument (from τέλος, telos, 'end, aim, goal'; also known as physico-theological argument, argument from design, or intelligent design argument) is an argument for the existence of God or, more generally, that complex functionality in the natural world which looks designed is evidence of an intelligent creator.
The earliest recorded versions of this argument are associated with Socrates in ancient Greece, although it has been argued that he was taking up an older argument. Plato and Aristotle developed complex approaches to the proposal that the cosmos has an intelligent cause, but it was the Stoics who, under their influence, "developed the battery of creationist arguments broadly known under the label 'The Argument from Design'".

The Proof of the Truthful (Arabic: برهان الصديقين, romanized: burhān al-ṣiddīqīn, also translated Demonstration of the Truthful or Proof of the Veracious, among others) is a formal argument for proving the existence of God introduced by the Islamic philosopherAvicenna (also known as Ibn Sina, 980–1037). Avicenna argued that there must be a "necessary existent" (Arabic: واجب الوجود, romanized: wājib al-wujūd), an entity that cannot not exist. The argument says that the entire set of contingent things must have a cause that is not contingent because otherwise it would be included in the set. Furthermore, through a series of arguments, he derived that the necessary existent must have attributes that he identified with God in Islam, including unity, simplicity, immateriality, intellect, power, generosity, and goodness.
Historian of philosophyPeter Adamson called the argument one of the most influential medieval arguments for God's existence, and Avicenna's biggest contribution to the history of philosophy. It was enthusiastically received and repeated (sometimes with modification) by later philosophers, including generations of Muslim philosophers, Western Christian philosophers such as Thomas Aquinas and Duns Scotus, and Jewish philosophers such as Maimonides.

David Émile Durkheim (French:[emildyʁkɛm] or [dyʁkajm], professionally known simply as Émile Durkheim; 15 April 1858 – 15 November 1917) was a French sociologist. Durkheim formally established the academic discipline of sociology and is commonly cited as one of the principal architects of modern social science, along with both Karl Marx and Max Weber.
Much of Durkheim's work was concerned with how societies can maintain their integrity and coherence in modernity, an era in which traditional social and religious ties are much less universal, and in which new social institutions have come into being. Durkheim's conception of the scientific study of society laid the groundwork for modern sociology, and he used such scientific tools as statistics, surveys, and historical observation in his analysis of suicides in Catholic and Protestant groups.

Huygens first identified the correct laws of elastic collision in his work De Motu Corporum ex Percussione, completed in 1656 but published posthumously in 1703. In 1659, Huygens derived geometrically the formula in classical mechanics for the centrifugal force in his work De vi Centrifuga, a decade before Newton. In optics, he is best known for his wave theory of light, which he described in his Traité de la Lumière (1690). His theory of light was initially rejected in favour of Newton's corpuscular theory of light, until Augustin-Jean Fresnel adapted Huygens's principle to give a complete explanation of the rectilinear propagation and diffraction effects of light in 1821. Today this principle is known as the Huygens–Fresnel principle. (Full article...)
Pinker is the Johnstone Family Professor of Psychology at Harvard University. He specializes in visual cognition and developmental linguistics, and his experimental topics include mental imagery, shape recognition, visual attention, regularity and irregularity in language, the neural basis of words and grammar, and childhood language development. Other experimental topics he works on are the psychology of cooperation and of communication, including emotional expression, euphemism, innuendo, and how people use "common knowledge", a term of art meaning the shared understanding in which two or more people know something, know that the other one knows, know the other one knows that they know, and so on.

The hard–easy effect is a cognitive bias that manifests itself as a tendency to overestimate the probability of one's success at a task perceived as hard, and to underestimate the likelihood of one's success at a task perceived as easy. The hard-easy effect takes place, for example, when individuals exhibit a degree of underconfidence in answering relatively easy questions and a degree of overconfidence in answering relatively difficult questions. "Hard tasks tend to produce overconfidence but worse-than-average perceptions," reported Katherine A. Burson, Richard P. Larrick, and Jack B. Soll in a 2005 study, "whereas easy tasks tend to produce underconfidence and better-than-average effects."
The hard-easy effect falls under the umbrella of "social comparison theory", which was originally formulated by Leon Festinger in 1954. Festinger argued that individuals are driven to evaluate their own opinions and abilities accurately, and social comparison theory explains how individuals carry out those evaluations by comparing themselves to others.

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?
