Left to right: Plato, Kant, Nietzsche, Buddha, Confucius, Averroes 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 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. Major branches of philosophy are epistemology, ethics, logic, and metaphysics. Epistemology studies what knowledge is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic is the study of correct reasoning and explores how good arguments can be distinguished from bad ones. Metaphysics examines the most general features of reality, existence, objects, and properties. Other subfields are aesthetics, philosophy of language, philosophy of mind, philosophy of religion, philosophy of science, philosophy of mathematics, philosophy of history, and political philosophy. Within each branch, there are competing schools of philosophy that promote different principles, theories, or methods. Philosophers use a great variety of methods to arrive at philosophical knowledge. They include conceptual analysis, reliance on common sense and intuitions, use of thought experiments, analysis of ordinary language, description of experience, and critical questioning. Philosophy is related to many other fields, including the sciences, mathematics, business, law, and journalism. It provides an interdisciplinary perspective and studies the scope and fundamental concepts of these fields. It also investigates their methods and ethical implications. (Full article...)

Augustine of Hippo (AD 354–430) as painted by Sandro Botticelli (c. 1445–1510). Augustine is credited with developing the first form of the theodicy now named for him. The Augustinian theodicy, named for the 4th- and 5th-century theologian and philosopher Augustine of Hippo, is a type of Christian theodicy 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.

Portrait by August Köhler, c. 1910, after 1627 original Johannes Kepler (/ˈkɛplər/; German: [joˈhanəs ˈkɛplɐ, -nɛs -] ⓘ; 27 December 1571 – 15 November 1630) was a German astronomer, mathematician, astrologer, natural philosopher and writer on music. He is a key figure in the 17th-century Scientific Revolution, best known for his laws of planetary motion, and his books Astronomia nova, Harmonice Mundi, and Epitome Astronomiae Copernicanae, influencing among others Isaac Newton, providing one of the foundations for his theory of universal gravitation. The variety and impact of his work made Kepler one of the founders and fathers of modern astronomy, the scientific method, natural and modern science. He has been described as the "father of science fiction" for his novel Somnium. 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. (Full article...) Title page, 1798 Maria: or, The Wrongs of Woman is Mary Wollstonecraft's unfinished novelistic sequel to her revolutionary political treatise A Vindication of the Rights of Woman (1792). The Wrongs of Woman was published posthumously in 1798 by her husband, William Godwin, and is often considered her most radical feminist work. 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...) Title page from the second edition of A Vindication of the Rights of Men, the first to carry Wollstonecraft's name A Vindication of the Rights of Men, in a Letter to the Right Honourable Edmund Burke; Occasioned by His Reflections on the Revolution in France (1790) is a political pamphlet, written by the 18th-century British writer and women's rights advocate Mary Wollstonecraft, which attacks aristocracy and advocates republicanism. Wollstonecraft's was the first response in a pamphlet war sparked by the publication of Edmund Burke's Reflections on the Revolution in France (1790), a defense of constitutional monarchy, aristocracy, and the Church of England. Wollstonecraft attacked not only hereditary privilege, but also the rhetoric that Burke used to defend it. Most of Burke's detractors deplored what they viewed as his theatrical pity for Marie Antoinette, but Wollstonecraft was unique in her love of Burke's gendered language. By saying the sublime and the beautiful, terms first established by Burke himself in A Philosophical Enquiry into the Origin of Our Ideas of the Sublime and Beautiful (1756), she kept his rhetoric as well as his argument. In her first unabashedly feminist critique, which Wollstonecraft scholar Claudia Johnson describes as unsurpassed in its argumentative force, Wollstonecraft indicts Burke's justification of an equal society founded on the passivity of women.

Putnam in 2006 Hilary Whitehall Putnam (/ˈpʌtnəm/; July 31, 1926 – March 13, 2016) was an American philosopher, mathematician, computer scientist, and figure in analytic philosophy in the second half of the 20th century. He contributed to the studies of philosophy of mind, philosophy of language, philosophy of mathematics, and philosophy of science. Outside philosophy, Putnam contributed to mathematics and computer science. Together with Martin Davis he developed the Davis–Putnam algorithm for the Boolean satisfiability problem and he helped demonstrate the unsolvability of Hilbert's tenth problem. 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. (Full article...) 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...) "Lisa the Skeptic" is the eighth episode of the ninth season of the American animated television series The Simpsons. It first aired on Fox in the United States on November 23, 1997. On an archaeological dig with her class, Lisa discovers a skeleton that resembles an angel. All of the townspeople believe that the skeleton actually came from an angel, but skeptical Lisa attempts to persuade them that there must be a rational scientific explanation. The episode's writer, David X. Cohen, developed the idea after visiting the American Museum of Natural History, and decided to loosely parallel themes from the Scopes Monkey Trial. The episode also makes allusions to actual hoaxes, such as the Cardiff Giant. 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...) Title page from the first edition of Locke's Some Thoughts Concerning Education (1693) 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. (Full article...) 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. One prevalent position in Islamic philosophy holds that religious language is meaningful and positive, demonstrating the shared attributes of God and His creatures. According to this view, the semantic commonality of attributes between God and humans indicates ontological commonalities between them. This is because factual concepts refer to and are abstracted from realities in the external world. (Full article...) Lenin in 1920 Vladimir Ilyich Ulyanov (22 April [O.S. 10 April] 1870 – 21 January 1924), better known as Vladimir Lenin, was a Russian revolutionary, politician and political theorist who was the founder and first head of government of Soviet Russia from 1917 until his death in 1924, and of the Soviet Union from 1922 until his death. The founder and leader of the Bolsheviks, Lenin led the October Revolution which established the world's first socialist state. His government won the Russian Civil War and consolidated power in a one-party state under the Communist Party. Ideologically a Marxist, his developments to the ideology are called Leninism. Born into a middle-class family in Simbirsk, Lenin embraced revolutionary socialist politics following his brother's 1887 execution. Expelled from Kazan Imperial University for participating in protests against the Tsarist government, he devoted the following years to a law degree before relocating to Saint Petersburg in 1893 and becoming a prominent Marxist activist. In 1897, Lenin was arrested for sedition and exiled to Siberia for three years. He then moved to Western Europe, where he became a key figure in the Marxist Russian Social Democratic Labour Party. In the party's 1903 schism, he led his Bolshevik faction against Julius Martov's Mensheviks. Lenin briefly returned to Russia during the failed Revolution of 1905, and during the First World War campaigned for its transformation into a Europe-wide proletarian revolution, which, as a Marxist, he believed would cause the end of capitalism and the rise of socialism. After the February Revolution of 1917 ousted Tsar Nicholas II and established a Provisional Government, Lenin returned to Russia and played a leading role in the October Revolution, in which the Bolsheviks overthrew the regime. (Full article...) Wollstonecraft c. 1797 Mary Wollstonecraft (UK: /ˈwʊlstənkrɑːft/ WUUL-stən-krahft, US: /-kræft/ -⁠kraft; 27 April 1759 – 10 September 1797) was a British writer, philosopher, and advocate of women's rights. Until the late 20th century, Wollstonecraft's life, which encompassed several unconventional (at the time) personal relationships, received more attention than her writing. Wollstonecraft is regarded as one of the founding feminist philosophers, and feminists often cite both her life and her works as important influences. During her brief career she wrote novels, treatises, a travel narrative, a history of the French Revolution, a conduct book, and a children's book. Wollstonecraft is best known for A Vindication of the Rights of Woman (1792), in which she argues that women are not naturally inferior to men but appear to be only because they lack education. She suggests that both men and women should be treated as rational beings and imagines a social order founded on reason. (Full article...) 1897 illustration of La Peau de chagrin, drawn by Adrien Moreau and published by George Barrie & Son La Peau de chagrin (French pronunciation: [la po də ʃaɡʁɛ̃], The Skin of Shagreen), known in English as The Magic Skin and The Wild Ass's Skin, is an 1831 novel 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...) Memorial in Nollendorfplatz, Berlin. Text in triangle: "Struck Dead Hushed Up [dedicated to] The homosexual victims of National Socialism" Text below: "The 'pink triangle' was the sign with which the National Socialists marked homosexuals in the concentration camps in a defamatory way. From January 1933 almost all homosexual locales in and around Nollendorfplatz were closed by the National Socialists or misused by raids to create 'pink lists' (homosexual files)." Before 1933, male homosexual acts were illegal in Germany under Paragraph 175 of the German Criminal Code. The law was not consistently enforced, however, and a thriving gay culture existed in major German cities. After the Nazi takeover in 1933, the first homosexual movement's infrastructure of clubs, organizations, and publications was shut down. After the Röhm purge in 1934, persecuting homosexuals became a priority of the Nazi police state. A 1935 revision of Paragraph 175 made it easier to bring criminal charges for homosexual acts, leading to a large increase in arrests and convictions. Persecution peaked in the years prior to World War II and was extended to areas annexed by Germany, including Austria, the Czech lands, and Alsace–Lorraine. The Nazi regime considered the elimination of all manifestations of homosexuality in Germany one of its goals. Men were often arrested after denunciation, police raids, and through information uncovered during interrogations of other homosexuals. Those arrested were presumed guilty, and subjected to harsh interrogation and torture to elicit a confession. Between 1933 and 1945, an estimated 100,000 men were arrested as homosexuals; around 50,000 of these were sentenced by civilian courts, 6,400 to 7,000 by military courts, and an unknown number by special courts. Most of these men served time in regular prisons, and between 5,000 and 6,000 were imprisoned in concentration camps. The death rate of these prisoners has been estimated at 60 percent, a higher rate than those of other prisoner groups. A smaller number of men were sentenced to death or killed at Nazi euthanasia centres. Nazi Germany's persecution of homosexuals is considered to be the most severe episode in a long history of discrimination and violence targeting sexual minorities. (Full article...) Political Animals and Animal Politics is a 2014 edited collection published by Palgrave Macmillan and edited by the green political theorists Marcel 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. In part, Political Animals and Animal Politics arose from a workshop that Wissenburg and Schlosberg organised at the 2012 European Consortium for Political Research Joint Sessions conference, though not all attendees contributed to the volume and not all contributors presented at the workshop. Footage of the workshop appeared in De Haas in de Marathon (The Pacer in the Marathon), a 2012 documentary about the Dutch Party for the Animals. Political Animals and Animal Politics was published as part of the Palgrave Macmillan Animal Ethics Series, edited by Andrew Linzey and Priscilla Cohn. (Full article...) Anekāntavāda (Sanskrit: अनेकान्तवाद, "many-sidedness", Tamil: பல்லுரை) 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 and viewpoints. 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...)

He wrote on diverse subjects, including physics, poetry, zoology, logic, rhetoric, politics, government, ethics, and biology. Aristotle, his teacher Plato, and his teacher Socrates, are generally considered the most influential of ancient Greek philosophers. They transformed Presocratic Greek philosophy into the foundations of Western philosophy as we know it. The writings of Plato and Aristotle founded two of the most important schools of Ancient philosophy. Aristotle was a polymath. He not only studied almost every subject possible at the time, but made significant contributions to most of them. In science, Aristotle studied anatomy, astronomy, economics, embryology, geography, geology, meteorology, physics, and zoology. In philosophy, Aristotle wrote on aesthetics, ethics, government, metaphysics, politics, psychology, rhetoric and theology. He also dealt with education, foreign customs, literature and poetry. His combined works practically constitute an encyclopedia of Greek knowledge... ...Archive Read more... Selected article of the week The Roman god Apollo is an anthropomorphic representation of the Sun. Anthropomorphism is the attribution of human characteristics and qualities to non-human beings, objects, natural, or supernatural phenomena. A form of personification (applying human or animal qualities to inanimate objects), anthropomorphism is similar to prosopopoeia (adopting the persona of another person). Animals, the forces of nature, and unseen or unknown authors of chance are frequent subjects of anthropomorphosis. In religion and mythology, "anthropomorphism" refers to the perception of a divine being or beings in human form, or the recognition of human qualities generally, in these beings. Many mythologies are almost entirely concerned with anthropomorphic deities who express human characteristics such as jealousy, hatred, or love. The Greek gods such as Zeus and Apollo were often depicted in human form exhibiting both commendable and despicable human traits.

Five uses of "think of the children" before the United States Congress "Think of the children" (also "What about the children?") is a cliché that evolved into a rhetorical tactic. In the literal sense, it refers to children's rights (as in discussions of child labor). In debate, it is a plea for pity that is used as an appeal to emotion, and therefore may become a logical fallacy. (Full article...) Philosophy of science is the branch of philosophy concerned with the foundations, methods, and implications of science. Amongst its central questions are the difference between science and non-science, the reliability of scientific theories, and the ultimate purpose and meaning of science as a human endeavour. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of scientific practice, and overlaps with metaphysics, ontology, logic, and epistemology, for example, when it explores the relationship between science and the concept of truth. Philosophy of science is both a theoretical and empirical discipline, relying on philosophical theorising as well as meta-studies of scientific practice. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science. Many of the central problems concerned with the philosophy of science lack contemporary consensus, including whether science can infer truth about unobservable entities and whether inductive reasoning can be justified as yielding definite scientific knowledge. Philosophers of science also consider philosophical problems within particular sciences (such as biology, physics and social sciences such as economics and psychology). Some philosophers of science also use contemporary results in science to reach conclusions about philosophy itself. (Full article...) Pre-Socratic philosophy, also known as Early Greek Philosophy, is ancient Greek philosophy before Socrates. Pre-Socratic philosophers were mostly interested in cosmology, the beginning and the substance of the universe, but the inquiries of these early philosophers spanned the workings of the natural world as well as human society, ethics, and religion. They sought explanations based on natural law rather than the actions of gods. Their work and writing has been almost entirely lost. Knowledge of their views comes from testimonia, i.e. later authors' discussions of the work of pre-Socratics. Philosophy found fertile ground in the ancient Greek world because of the close ties with neighboring civilizations and the rise of autonomous civil entities, poleis. Pre-Socratic philosophy began in the 6th century BC with the three Milesians: Thales, Anaximander, and Anaximenes. They all attributed the arche (a word that could take the meaning of "origin", "substance" or "principle") of the world to, respectively, water, apeiron (the unlimited), and air. Another three pre-Socratic philosophers came from nearby Ionian towns: Xenophanes, Heraclitus, and Pythagoras. Xenophanes is known for his critique of the anthropomorphism of gods. Heraclitus, who was notoriously difficult to understand, is known for his maxim on impermanence, ta panta rhei, and for attributing fire to be the arche of the world. Pythagoras created a cult-like following that advocated that the universe was made up of numbers. The Eleatic school (Parmenides, Zeno of Elea, and Melissus) followed in the 5th century BC. Parmenides claimed that only one thing exists and nothing can change. Zeno and Melissus mainly defended Parmenides' opinion. Anaxagoras and Empedocles offered a pluralistic account of how the universe was created. Leucippus and Democritus are known for their atomism, and their views that only void and matter exist. The Sophists advanced philosophical relativism. The Pre-Socratics have had significant impact on several concepts of Western philosophy, such as naturalism and rationalism, and paved the way for scientific methodology. (Full article...) Jain temples on Shatrunjaya hill near Palitana, Gujarat Jainism (/ˈdʒeɪnɪzəm/ JAY-niz-əm), also known as Jain Dharma, is an Indian religion. Jainism traces its spiritual ideas and history through the succession of twenty-four tirthankaras (supreme preachers of Dharma), with the first in the current time cycle being Rishabhadeva, whom the tradition holds to have lived millions of years ago, the twenty-third tirthankara Parshvanatha, whom historians date to the 9th century BCE, and the twenty-fourth tirthankara Mahavira, around 600 BCE. Jainism is considered an eternal dharma with the tirthankaras guiding every time cycle of the cosmology. Central to understanding Jain philosophy is the concept of bhedvigyān, or the clear distinction in the nature of the soul and non-soul entities. This principle underscores the innate purity and potential for liberation within every soul, distinct from the physical and mental elements that bind it to the cycle of birth and rebirth. Recognizing and internalizing this separation is essential for spiritual progress and the attainment of samyak darshan or self realization, which marks the beginning of the aspirant's journey towards liberation. The three main pillars of Jainism are ahiṃsā (non-violence), anekāntavāda (non-absolutism), and aparigraha (asceticism). Jain monks take five main vows: ahiṃsā (non-violence), satya (truth), asteya (not stealing), brahmacharya (chastity), and aparigraha (non-possessiveness). These principles have affected Jain culture in many ways, such as leading to a predominantly lacto-vegetarian lifestyle. Parasparopagraho jīvānām (the function of souls is to help one another) is the faith's motto, and the Namokar Mantra is its most common and strongest prayer. (Full article...) Panait Cerna (Romanian pronunciation: [panaˈit ˈt͡ʃerna]; 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. A graduate of the University of Bucharest, Cerna completed his studies in the German Empire. There, he attended the University of Berlin and the University of Leipzig, befriending the self-exiled Romanian dramatist Ion Luca Caragiale and the literary critic Paul Zarifopol. Cerna died in Leipzig at the age of thirty-one, after a long battle with tuberculosis. (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 was born in Råshult, in the countryside of Småland, 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...) Title Page of first American edition Natural Theology or Evidences of the Existence and Attributes of the Deity is an 1802 work of Christian apologetics and philosophy of religion by the English clergyman William Paley (1743–1805). The book expounds his arguments from natural theology, making a teleological argument for the existence of God, notably beginning with the watchmaker analogy. The book was written in the context of the natural theology tradition. In earlier centuries, theologians such as John Ray and William Derham, as well as philosophers of classical times such as Cicero, argued for the existence and goodness of God from the general well-being of living things and the physical world.

January 20], 1905 – March 6, 1982), better known by her pen name Ayn Rand (/aɪn/), was a Russian-born American author and philosopher. She is known for her fiction and for developing a philosophical system she named Objectivism. Born and educated in Russia, she moved to the United States in 1926. After two early novels that were initially unsuccessful and two Broadway plays, Rand achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-selling work, the novel Atlas Shrugged. Afterward, until her death in 1982, she turned to non-fiction to promote her philosophy, publishing her own periodicals and releasing several collections of essays. Rand advocated reason and rejected faith and religion. She supported rational and ethical egoism as opposed to altruism and hedonism. In politics, she condemned the initiation of force as immoral and supported laissez-faire capitalism, which she defined as the system based on recognizing individual rights, including private property rights. Although she opposed libertarianism, which she viewed as anarchism, Rand is often associated with the modern libertarian movement in the United States. In art, she promoted romantic realism. She was sharply critical of most philosophers and philosophical traditions known to her, with a few exceptions. (Full article...) The Iranian Enlightenment (Persian: روشنگری ایرانی), sometimes called the first generation of intellectual movements in Iran (Persian: نسل اول جنبش های روشنفکری در ایران), brought new ideas into traditional Iranian society from the mid-nineteenth to the early twentieth century. During the rule of the Qajar dynasty, and especially after the defeat of Iran in its war with the Russian Empire, cultural exchanges led to the formation of new ideas among the educated class of Iran.The establishment of Dar ul-Fonun, the first modern university in Iran and the arrival of foreign professors, caused the thoughts of European thinkers to enter Iran, followed by the first signs of enlightenment and intellectual movements in Iran. During this period, intellectual groups were formed in secret societies and secret associations. These secret societies included Mirza Malkam Khan's Faramosh Khaneh (based on Masonic lodges), Anjoman-e Okhovat, Society of Humanity and Mokhadarat Vatan Association. These groups spread their ideas by distributing leaflets and newspapers. These secret societies stressed the need to reform the land and administrative system and reduce the role of the clergy in society, as well as to limit the rulers within the framework of the law.

It marked the transition from the Middle Ages to modernity and was characterized by an effort to revive and surpass the ideas and achievements of classical antiquity. Associated with great social change in most fields and disciplines, including art, architecture, politics, literature, exploration and science, the Renaissance was first centered in the Republic of Florence, then spread to the rest of Italy and later throughout Europe. The term rinascita ("rebirth") first appeared in Lives of the Artists (c. 1550) by Giorgio Vasari, while the corresponding French word renaissance was adopted into English as the term for this period during the 1830s. The Renaissance's intellectual basis was founded in its version of humanism, derived from the concept of Roman humanitas and the rediscovery of classical Greek philosophy, such as that of Protagoras, who said that "man is the measure of all things". Although the invention of metal movable type sped the dissemination of ideas from the later 15th century, the changes of the Renaissance were not uniform across Europe: the first traces appear in Italy as early as the late 13th century, in particular with the writings of Dante and the paintings of Giotto. (Full article...) The Demands of Liberal Education is a 1999 political philosophy book by Meira Levinson that establishes a liberal political theory of children's education that fits the mutual needs of the state and its diverse citizenry. She writes that the intent of a liberal education—an education that follows from a liberal society's values—is to maximize the autonomy of individual children through increasing their capacity for liberty. Levinson argues autonomy as a right to children. The book, published by Oxford University Press, aims to address a lacuna between educational policy and liberal political theory. Levinson advocates for a weak perfectionist state that can promote thick autonomy while accepting citizens who do not agree. She argues for public schools "common" to all citizens and "detached" from individual citizen or community values, and argues for a constitutional mandate to this end. (Full article...) Representation of consciousness from the 17th century by Robert Fludd, an English Paracelsian physician 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, scientists, and theologians. 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 it. 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, metacognition, 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. Examples of the range of descriptions, definitions or explanations are: ordered distinction between self and environment, simple wakefulness, one's sense of selfhood or soul explored by "looking within"; being a metaphorical "stream" of contents, or being a mental state, mental event, or mental process of the brain. (Full article...) Title page of the second edition. Letters from an American Farmer is a series of letters written by French American writer J. Hector St. John de Crèvecœur, first published in 1782. The considerably longer title under which it was originally published is Letters from an American Farmer; Describing Certain Provincial Situations, Manners, and Customs not Generally Known; and Conveying Some Idea of the Late and Present Interior Circumstances of the British Colonies in North America. The twelve letters cover a wide range of topics, from the emergence of an American identity to the slave trade. Crèvecœur wrote Letters during a period of seven years prior to the American Revolutionary War, while farming in the fertile Greycourt, blackdirt region of Chester, NY, a small town in Orange County, New York. It is told from the viewpoint of a fictional narrator in correspondence with an English gentleman, and each letter concerns a different aspect of life or location in the British colonies of America. The work incorporates a number of styles and genres, including documentary, as well as sociological observations. (Full article...) Weber in 1918 Maximilian Carl Emil Weber (/ˈveɪbər/; German: [maks ˈveːbɐ]; 21 April 1864 – 14 June 1920) was a German sociologist, historian, jurist, and political economist who was one of the central figures in the development of sociology and the social sciences more generally. His ideas continue to influence social theory and research. Born in Erfurt in 1864, Weber studied law and history in Berlin, Göttingen, and Heidelberg. After earning his doctorate in law in 1889 and habilitation in 1891, he taught in Berlin, Freiburg, and Heidelberg. He married his cousin Marianne Schnitger two years later. In 1897, he had a breakdown after his father died following an argument. Weber ceased teaching and travelled until the early 1900s. He recovered and wrote The Protestant Ethic and the Spirit of Capitalism. During the First World War, he initially supported Germany's war effort but became critical of it and supported democratisation. He also gave the lectures "Science as a Vocation" and "Politics as a Vocation". After the war, Weber co-founded the German Democratic Party, unsuccessfully ran for office, and advised the drafting of the Weimar Constitution. Becoming frustrated with politics, he resumed teaching in Vienna and Munich. He died of pneumonia in 1920 at the age of 56, possibly as a result of the post-war Spanish flu pandemic. A book, Economy and Society, was left unfinished. (Full article...) Vyāsatīrtha (c. 1460 – c. 1539), also called Vyasaraja or Chandrikacharya, was a Hindu philosopher, scholar, polemicist, commentator and poet belonging to the Madhwacharya's Dvaita order of Vedanta. As the rajaguru of Vijayanagara Empire, Vyasatirtha was at the forefront of a golden age in Dvaita which saw new developments in dialectical thought, growth of the Haridasa literature under bards like Purandara Dasa and Kanaka Dasa and an increased spread of Dvaita across the subcontinent. He himself composed many kīrtanas in Kannada and Sanskrit. Three of his polemically themed doxographical works Nyayamruta, Tatparya Chandrika and Tarka Tandava (collectively called Vyasa Traya) documented and critiqued an encyclopaedic range of sub-philosophies in Advaita, Visistadvaita, Mahayana Buddhism, Mimamsa and Nyaya, revealing internal contradictions and fallacies. His Nyayamruta caused a stir in the Advaita community across the country requiring a rebuttal by Madhusudhana Saraswati through his text, Advaitasiddhi. He is considered as an amsha of Prahlada in the Madhva Parampara. (Full article...) General images - The following are images from various philosophy-related articles on Wikipedia.

Topics Glossary · Outline  · A–Z index  · Featured content Academic Branches of Philosophy 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?
