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.

In the philosophy of Baruch Spinoza, conatus (/koʊˈneɪtəs/; wikt:conatus; Latin for "effort; endeavor; impulse, inclination, tendency; undertaking; striving") is an innate inclination of a thing to continue to exist and enhance itself. This thing may be mind, matter, or a combination of both, and is often associated with God's will in a pantheist view of nature. The conatus may refer to the instinctive will to live of living organisms or to various metaphysical theories of motion and inertia. Today, conatus is rarely used in the technical sense, since classical mechanics uses concepts such as inertia and conservation of momentum that have superseded it. It has, however, been a notable influence on later thinkers such as Arthur Schopenhauer and Friedrich Nietzsche. (Full article...)
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...)

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

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...)

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.
It has been discussed in the context of ontology, existentialism, and skepticism; it has also been used in Christian religious education classes to initiate discussion about angels, science, and faith. (Full article...)
Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philosophy. (Full article...)

The 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...)
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.

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).

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.
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...)
Jacques-Marie-Émile Lacan (April 13, 1901 – September 9, 1981) was a Frenchpsychoanalyst and psychiatrist. His work, like most psychoanalytic work, owes a heavy, explicit debt to Sigmund Freud, but also drew from a number of other fields, including linguistics, philosophy, and mathematics. This interdisciplinary focus in his work has led him to be an important figure in many fields beyond psychoanalysis - particularly within critical theory.
His central idea was that the human subject is a creation of its use of language. From this understanding Lacan develops his study of psychoanalysis and his treatment strategies. His work, while controversial, continues to influence the development of psychoanalysis worldwide. In France and elsewhere various "schools" of Lacanian thought have emerged.
Non-cognitivism is the meta-ethical view that moral statements lack truth-value and do not assert propositions. A noncognitivist denies the cognitivist claim that "moral judgments are capable of being objectively true, because they describe some feature of the world." If moral statements cannot be true, and if one cannot know something that is not true, noncognitivism implies that moral knowledge is impossible.
While the bare term non-cognitivism usually refers to ethics, it can also be applied in other branches of philosophy, as in theological noncognitivism.
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...)

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.

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...)

Panait Cerna (Romanian pronunciation:[panaˈitˈt͡ʃerna]; Bulgarian: Панайот Черна, Panayot Cherna, born Panayot Stanchov or Panait Staciov; August 26 or September 25, 1881 – March 26, 1913) was a Romanian poet, philosopher, literary critic and translator. A native speaker of Bulgarian, Cerna nonetheless wrote in Romanian, and developed a traditionalist style which was connected with classicism and neoclassicism. Praised by the conservative literary society Junimea, he was promoted by its leader Titu Maiorescu, as well as by Maiorescu's disciples Mihail Dragomirescu and Simion Mehedinţi. Cerna became the group's main representative during its decline, contributing to both major Junimist magazines, Convorbiri Literare and Convorbiri Critice. He also contributed pieces to the traditionalist magazine Sămănătorul, and was briefly affiliated with other literary journals.
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...)

J. R. R. Tolkien's bestselling fantasy novel The Lord of the Rings had an initial mixed literary reception. Despite some enthusiastic early reviews from supporters such as W. H. Auden, Iris Murdoch, and C. S. Lewis, literary hostility to Tolkien quickly became acute and continued until the start of the 21st century. From 1982, Tolkien scholars such as Tom Shippey and Verlyn Flieger began to roll back the hostility, defending Tolkien, rebutting the critics' attacks and analysing what they saw as good qualities in Tolkien's writing.
From 2003, scholars such as Brian Rosebury began to consider why Tolkien had attracted such hostility. Rosebury noted that Tolkien avoided calling The Lord of the Rings a novel, and that in Shippey's view Tolkien had been aiming to create a medieval-style heroic romance, despite modern scepticism about that literary mode. In 2014, Patrick Curry analysed the reasons for the hostility, finding it both visceral and full of evident mistakes, and suggesting that the issue was that the critics felt that Tolkien threatened their dominant ideology, modernism.

Cynicism (Ancient Greek: κυνισμός) is a school of thought in ancient Greek philosophy, originating in the Classical period and extending into the Hellenistic and Roman Imperial periods. According to Cynicism, people are reasoning animals, and the purpose of life and the way to gain happiness is to achieve virtue, in agreement with nature, following one's natural sense of reason by living simply and shamelessly free from social constraints. The Cynics (Ancient Greek: Κυνικοί, Latin: Cynici) rejected all conventional desires for wealth, power, glory, social recognition, conformity, and worldly possessions and even flouted such conventions openly and derisively in public.
The first philosopher to outline these themes was Antisthenes, who had been a pupil of Socrates in the late 400s BC. He was followed by Diogenes, who lived in a ceramic jar on the streets of Athens. Diogenes took Cynicism to its logical extremes with his famous public demonstrations of non-conformity, coming to be seen as the archetypal Cynic philosopher. He was followed by Crates of Thebes, who gave away a large fortune so he could live a life of Cynic poverty in Athens. (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...)

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.
The Upanishad describes four kinds of sannyasins (Hindu monks), their eating habits and lifestyle. Yoga is the path of spiritual liberation for all four. Of these, the Paramahamsa monks are discussed in this text at greater length, and described as loners who are patient with everyone, free from dualism in their thoughts, and who meditate on their soul and the Brahman.

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...)

Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné, was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as Carolus Linnæus and, after his 1761 ennoblement, as Carolus a Linné.
Linnaeus was the son of a curate and he was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his Systema Naturae in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, while publishing several volumes. By the time of his death in 1778, he was one of the most acclaimed scientists in Europe. (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?
