Philosophy ('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 methods and assumptions.
Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western, Arabic–Persian, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues about right social conduct, government, and self-cultivation.
Wallace did extensive fieldwork, starting in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species, and is sometimes called the "father of biogeography", or more specifically of zoogeography.

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...)

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).

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.
Anarky is an anti hero 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 reflections 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...)
Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. After completing graduate work at Harvard University, where he was the 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 chance for advanced education to develop their leadership.

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. Putnam also originated the computational theory of mind. 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.

Sir Bernard Arthur Owen WilliamsFBA (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.
Ion Heliade Rădulescu or Ion Heliade (also known as Eliade or Eliade Rădulescu; Romanian pronunciation:[ˈi.on(h)eliˈaderəduˈlesku]; 6 January 1802 – 27 April 1872) was a Wallachian, later Romanian academic, Romantic and Classicist poet, essayist, memoirist, short story writer, newspaper editor and politician. A prolific translator of foreign literature into Romanian, he was also the author of books on linguistics and history. For much of his life, Heliade Rădulescu was a teacher at Saint Sava College in Bucharest, which he helped reopen. He was a founding member and first president of the Romanian Academy.
Heliade Rădulescu is considered one of the foremost champions of Romanian culture from the first half of the 19th century, having first risen to prominence through his association with Gheorghe Lazăr and his support of Lazăr's drive for discontinuing education in Greek. Over the following decades, he had a major role in shaping the modern Romanian language, but caused controversy when he advocated the massive introduction of 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.

Athonite Fresco Icon of Saint Maximos the Confessor
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.

Priestley, painted late in life by Rembrandt Peale (c. 1800)
A member of marginalized religious groups throughout his life and a proponent of what was called "rational Dissent," Priestley advocated religious toleration and equal rights for Dissenters. He argued for extensive civil rights in works such as the important Essay on the First Principles of Government, believing that individuals could bring about progress and eventually the Millennium; he was the foremost British expounder of providentialism. Priestley also made significant contributions to education, publishing, among other things, The Rudiments of English Grammar, a seminal work on English grammar. In his most lasting contributions to education, he argued for the benefits of a liberal arts education and of the value of the study of modern history. In his metaphysical works, Priestley "attempt[ed] to combine theism, materialism, and determinism," a project that has been called "audacious and original." (Full article...)

Mary Wollstonecraft by John Opie (c. 1791) The lifetime of British writer, philosopher, and feministMary Wollstonecraft (1759–1797) encompassed most of the second half of the eighteenth century, a time of great political and social upheaval throughout Europe and America: political reform movements in Britain gained strength, the American colonists successfully rebelled, and the French Revolution erupted. Wollstonecraft experienced only the headiest of these days, not living to see the end of the democratic revolution when Napoleon crowned himself emperor. Although Britain was still revelling in its mid-century imperial conquests and its triumph in the Seven Years' War, it was the French revolution that defined Wollstonecraft's generation. As poet Robert Southey later wrote: "few persons but those who have lived in it can conceive or comprehend what the memory of the French Revolution was, nor what a visionary world seemed to open upon those who were just entering it. Old things seemed passing away, and nothing was dreamt of but the regeneration of the human race."
Part of what made reform possible in Britain in the second half of the eighteenth century was the dramatic increase in publishing; books, periodicals, and pamphlets became much more widely available than they had been just a few decades earlier. This increase in available printed material helped facilitate the rise of the British middle class. Reacting against what they viewed as aristocratic decadence, the new professional middle classes (made prosperous through British manufacturing and trade), offered their own ethical code: reason, meritocracy, self-reliance, religious toleration, free inquiry, free enterprise, and hard work. They set these values against what they perceived as the superstition and unreason of the poor and the prejudices, censorship, and self-indulgence of the rich. They also helped establish what has come to be called the "cult of domesticity", which solidified gender roles for men and women. This new vision of society rested on the writings of Scottish Enlightenment philosophers such as Adam Smith, who had developed a theory of social progress founded on sympathy and sensibility. A partial critique of the rationalist Enlightenment, these theories promoted a combination of reason and feeling that enabled women to enter the public sphere because of their keen moral sense. Wollstonecraft's writings stand at the nexus of all of these changes. Her educational works, such as her children's bookOriginal Stories from Real Life (1788), helped inculcate middle-class values, and her two Vindications, A Vindication of the Rights of Men (1790) and A Vindication of the Rights of Woman (1792), argue for the value of an educated, rational populace, specifically one that includes women. In her two novels, Mary: A Fiction and Maria: or, The Wrongs of Woman, she explores the ramifications of sensibility for women. (Full article...)

Portrait by August Köhler, c. 1910, after 1620 original
Kepler was a mathematics teacher at a seminary school in Graz, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to the astronomer Tycho Brahe in Prague, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He also taught mathematics in Linz, and was an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, being named the father of modern optics, in particular for his Astronomiae pars optica. He also invented an improved version of the refracting telescope, the Keplerian telescope, which became the foundation of the modern refracting telescope, while also improving on the telescope design by Galileo Galilei, who mentioned Kepler's discoveries in his work. He is also known for postulating the Kepler conjecture. (Full article...)

Determinism is the philosophical proposition that every event, including human cognition and action, is causally determined by an unbroken chain of prior occurrences. No mysterious miracles or wholly random events occur.
The principal consequence of deterministic philosophy is that free will (except as defined in strict compatibilism) becomes an illusion. It is a popular misconception that determinism necessarily entails that all future events have already been predetermined and will necessarily happen (a position known as Fatalism); this is not obviously the case, and the subject is still debated among metaphysicists. Determinism is associated with, and relies upon, the ideas of Materialism and Causality. Some of the philosophers who have dealt with this issue are Omar Khayyám, David Hume, Thomas Hobbes, Immanuel Kant, and, more recently, John Searle.
These are Good articles, which meet a core set of high editorial standards.

The illusory truth effect (also known as the illusion of truth effect, validity effect, truth effect, or the reiteration effect) is the tendency to believe false information to be correct after repeated exposure. This phenomenon was first identified in a 1977 study at Villanova University and Temple University. When truth is assessed, people rely on whether the information is in line with their understanding or if it feels familiar. The first condition is logical, as people compare new information with what they already know to be true. Repetition makes statements easier to process relative to new, unrepeated statements, leading people to believe that the repeated conclusion is more truthful. The illusory truth effect has also been linked to hindsight bias, in which the recollection of confidence is skewed after the truth has been received.
In a 2015 study, researchers discovered that familiarity can overpower rationality and that repetitively hearing that a certain statement is wrong can paradoxically cause it to feel right. Researchers observed the illusory truth effect's impact even on participants who knew the correct answer to begin with but were persuaded to believe otherwise through the repetition of a falsehood, to "processing fluency".

Robert returned to England in 1160, and was appointed Bishop of Hereford in 1163. King Henry II of England appointed him to the see, or bishopric, and was influenced in his decision by Pope Alexander III and Thomas Becket. Following his consecration, Robert became involved in the dispute between Becket and the king, during which he generally took the king's side. He also served as a papal and a royal judge.

Dreamtime opens with the premise that many of those accused of witchcraft in early modern Christendom had been undergoing visionary journeys with the aid of a hallucinogenic salve which was suppressed by the Christian authorities. Duerr argues that this salve had been a part of the nocturnal visionary traditions associated with the goddess Diana, and he attempts to trace their origins back to the ancient world, before looking at goddesses associated with the wilderness and arguing that in various goddess-centred cultures, the cave represented a symbolic vagina and was used for birth rituals.

Cries and Whispers (Swedish: Viskningar Och Rop, lit. 'Whispers and cries') is a 1972 Swedish tragedy 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...)
The Kingdom of This World (Spanish: El reino de este mundo) is a novel by Cuban author Alejo Carpentier, published in 1949 in his native Spanish and first translated into English in 1957. A work of historical fiction, it tells the story of Haiti before, during, and after the Haitian Revolution led by Toussaint Louverture, as seen by its central character, Ti Noel, who serves as the novel's connecting thread. Carpentier's work has been influenced by his multi-cultural experience and his passion for the arts, as well as by authors such as Miguel de Cervantes. The novel stems from the author's desire to retrace the roots and history of the New World, and is embedded with what Carpentier calls "lo real maravilloso" or "the marvelous real"—a concept he introduced to the world of literature (not to be confused with magical realism).
Throughout the novel, varying perceptions of reality that arise due to cultural differences between its characters are emphasized and contrasted. Carpentier explores hybridization, nature, voodoo, ethnicity, history and destiny, confusion, violence, and sexuality in a style that blends history with fiction and uses repetition to emphasize the cyclical nature of events. The novel was largely well-received with much attention paid to Carpentier's inclusion of magic realism and The Kingdom of This World has been described as an important work in the development of this genre in Caribbean and Latin American literature. However, some technical aspects of his style have been ignored by the academic community, and the novel's narrative organization has been criticized. (Full article...)
With the publication of "A Dynamical Theory of the Electromagnetic Field" in 1865, Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. He proposed that light is an undulation in the same medium that is the cause of electric and magnetic phenomena. The unification of light and electrical phenomena led to his prediction of the existence of radio waves, and the paper contained his final version of his equations, which he had been working on since 1856. As a result of his equations, and other contributions such as introducing an effective method to deal with network problems and linear conductors, he is regarded as a founder of the modern field of electrical engineering. In 1871, Maxwell became the first Cavendish Professor of Physics, serving until his death in 1879. (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...)

The castle in the first circle of hell, as illustrated by Stradanus
The first 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 hell ordered into nine circles corresponding to classifications of sin. The first circle is Limbo, the space reserved for those souls who died before baptism and for those who hail from non-Christian cultures. They live eternally in a castle set on a verdant landscape, but forever removed from heaven.
Dante's depiction of Limbo is influenced by contemporary scholastic teachings on two kinds of Limbo—the Limbo of Infants for the unbaptised and the Limbo of the Patriarchs for the virtuous Jews of the Old Testament; the addition of Islamic, Greek, and Roman historical figures to the poem is an invention of Dante's, which has received criticism both in his own time and from a modern perspective. Dante also uses his depiction of Limbo to discuss the Harrowing of Hell, using the motif to explore the concept of predestination. (Full article...)

Henle in 1972
Robert John HenleSJ (September 12, 1909 – January 20, 2000) was an American Catholic priest, Jesuit, and philosopher who was the president of Georgetown University from 1969 to 1976. Born in Iowa, Henle entered the Society of Jesus in 1927. He taught high school classics and published a series of instructional books on Latin, one of which became widely used. He then became a professor at Saint Louis University and was known as one of the leaders of the revival of Thomistic philosophy and theology. He also served as a dean and vice president for nearly 20 years. In this latter capacity, he oversaw Saint Louis University's growing independence from, but continuing affiliation with, the Jesuit order.
In 1969, Henle was named the president of Georgetown University. He presided over an era of rapid growth and a diversifying student body. The student population grew and Henle stabilized the university's finances. Women were admitted for the first time to Georgetown College, the last all-male school at the university, while the number of black students increased. He also hired John Thompson, one of the first black coaches of a major collegiate basketball team, who later led the team to an NCAA championship in 1984. (Full article...)

Roman copy (in marble) of a Greek bronze bust of Aristotle by Lysippos (c. 330 BC), with modern alabaster mantle
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 around eighteen years old, he joined Plato's Academy in Athens and remained there until the age of thirty seven (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...)
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.

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?
