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.

Goldman, c. 1911
Emma Goldman (June 27, 1869 – May 14, 1940) was a Lithuanian-born anarchistrevolutionary, political activist, and writer. She played a pivotal role in the development of anarchist political philosophy in North America and Europe in the first half of the 20th century.
Born in Kaunas, Lithuania (then within the Russian Empire), to an OrthodoxLithuanian Jewish family, Goldman emigrated to the United States in 1885. Attracted to anarchism after the Chicago Haymarket affair, Goldman became a writer and a renowned lecturer on anarchist philosophy, women's rights, and social issues, attracting crowds of thousands. She and anarchist writer Alexander Berkman, her lover and lifelong friend, planned to assassinate industrialist and financier Henry Clay Frick as an act of propaganda of the deed. Frick survived the attempt on his life in 1892, and Berkman was sentenced to 22 years in prison. Goldman was imprisoned several times in the years that followed, for "inciting to riot" and illegally distributing information about birth control. In 1906, Goldman founded the anarchist journal Mother Earth. (Full article...)

Some Thoughts Concerning Education is a 1693 treatise on the education of gentlemen written by the English philosopher John Locke. For over a century, it was the most important philosophical work on education in England. It was translated into almost all of the major written European languages during the eighteenth century, and nearly every European writer on education after Locke, including Jean-Jacques Rousseau, acknowledged its influence.
In his Essay Concerning Human Understanding (1690), Locke outlined a new theory of mind, contending that the mind is originally a tabula rasa or "blank slate"; that is, it did not contain any innate ideas at birth. Some Thoughts Concerning Education explains how to educate that mind using three distinct methods: the development of a healthy body; the formation of a virtuous character; and the choice of an appropriate academic curriculum.

Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. After completing graduate work at the Friedrich Wilhelm University in Berlin and Harvard University, where he was its first African American to earn a doctorate, Du Bois rose to national prominence as a leader of the Niagara Movement, a group of black civil rights activists seeking equal rights. Du Bois and his supporters opposed the Atlanta Compromise. Instead, Du Bois insisted on full civil rights and increased political representation, which he believed would be brought about by the African-American intellectual elite. He referred to this group as the Talented Tenth, a concept under the umbrella of racial uplift, and believed that African Americans needed the chances for advanced education to develop its leadership.

The Augustinian theodicy, named for the 4th- and 5th-century theologian and philosopher Augustine of Hippo, is a type of Christiantheodicy that developed in response to the evidential problem of evil. As such, it attempts to explain the probability of an omnipotent (all-powerful) and omnibenevolent (all-loving) God amid evidence of evil in the world. A number of variations of this kind of theodicy have been proposed throughout history; their similarities were first described by the 20th-century philosopher John Hick, who classified them as "Augustinian". They typically assert that God is perfectly (ideally) good, that he created the world out of nothing, and that evil is the result of humanity's original sin. The entry of evil into the world is generally explained as consequence of original sin and its continued presence due to humans' misuse of free will and concupiscence. God's goodness and benevolence, according to the Augustinian theodicy, remain perfect and without responsibility for evil or suffering.
Augustine of Hippo was the first to develop the theodicy. He rejected the idea that evil exists in itself, instead regarding it as a corruption of goodness, caused by humanity's abuse of free will. Augustine believed in the existence of a physical Hell as a punishment for sin, but argued that those who choose to accept the salvation of Jesus Christ will go to Heaven. In the 13th century, Thomas Aquinas – influenced by Augustine – proposed a similar theodicy based on the view that God is goodness and that there can be no evil in him. He believed that the existence of goodness allows evil to exist, through the fault of humans. Augustine also influenced John Calvin, who supported Augustine's view that evil is the result of free will and argued that sin corrupts humans, requiring God's grace to give moral guidance.

Anekāntavāda (Sanskrit: अनेकान्तवाद, "many-sidedness") is the Jain doctrine about metaphysical truths that emerged in ancient India. It states that the ultimate truth and reality is complex and has multiple aspects.
According to Jainism, no single, specific statement can describe the nature of existence and the absolute truth. This knowledge (Kevala Jnana), it adds, is comprehended only by the Arihants. Other beings and their statements about absolute truth are incomplete, and at best a partial truth. All knowledge claims, according to the anekāntavāda doctrine must be qualified in many ways, including being affirmed and denied. Anekāntavāda is a fundamental doctrine of Jainism. (Full article...)
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).

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.

Confirmation bias (also confirmatory bias, myside bias, or congeniality bias) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for emotionally charged issues, and for deeply entrenched beliefs. Confirmation bias is insuperable for most people, but they can manage it, for example, by education and training in critical thinking skills.
Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects:
attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence)
belief perseverance (when beliefs persist after the evidence for them is shown to be false)
the irrational primacy effect (a greater reliance on information encountered early in a series)
illusory correlation (when people falsely perceive an association between two events or situations).
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...)

Wollstonecraft c. 1797
Mary Wollstonecraft (/ˈwʊlstənkræft/, also UK: /-krɑːft/; 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 personal relationships at the time, received more attention than her writing. Today 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:[lapodəʃaɡʁɛ̃], The Skin of Shagreen), known in English as The Magic Skin and The Wild Ass's Skin, is an 1831novel by French novelist and playwright Honoré de Balzac (1799–1850). Set in early 19th-century Paris, it tells the story of a young man who finds a magic piece of shagreen (untanned skin from a wild ass) that fulfills his every desire. For each wish granted, however, the skin shrinks and consumes a portion of his physical energy. La Peau de chagrin belongs to the Études philosophiques group of Balzac's sequence of novels, La Comédie humaine.
Before the book was completed, Balzac created excitement about it by publishing a series of articles and story fragments in several Parisian journals. Although he was five months late in delivering the manuscript, he succeeded in generating sufficient interest that the novel sold out instantly upon its publication. A second edition, which included a series of twelve other "philosophical tales", was released one month later. (Full article...)

H. L. A. Hart (Herbert Lionel Adolphus Hart) (1907-1992) is widely regarded as the most important English-speakinglegal philosopher of the twentieth century. He was Professor of Jurisprudence at Oxford University and is the author of The Concept of Law. Hart developed a sophisticated theory of legal positivism within the framework of analytic philosophy: He maintained that there is no necessary connection between law and morality; that for a legal system to be efficient there must be secondary legal rules to alter any primary legal rules of obligation; and that rules must be socially acceptable and recognized for them to be valid. Hart also made major contributions to political philosophy.
A paradox is a true statement or group of statements that leads to a contradiction or a situation which defies intuition. The term is also used for an apparent contradiction that actually expresses a non-dual truth (cf.kōan, Catuskoti). Typically, the statements in question do not really imply the contradiction, the puzzling result is not really a contradiction, or the premises themselves are not all really true or cannot all be true together. The word paradox is often used interchangeably with contradiction. It is also used to describe situations that are ironic.

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

Mathematics and architecture are related, since, as with other arts, architects use mathematics for several reasons. Apart from the mathematics needed when engineering buildings, architects use geometry: to define the spatial form of a building; from the Pythagoreans of the sixth century BC onwards, to create forms considered harmonious, and thus to lay out buildings and their surroundings according to mathematical, aesthetic and sometimes religious principles; to decorate buildings with mathematical objects such as tessellations; and to meet environmental goals, such as to minimise wind speeds around the bases of tall buildings.
Manilal Nabhubhai Dwivedi (pronounced[məɲilalnəbʰubʰaidvivedi]ⓘ; 26 September 1858 – 1 October 1898) was a Gujarati-language writer, philosopher, and social thinker from British India, commonly referred to as Manilal in literary circles. He was an influential figure in 19th-century Gujarati literature, and was one of several Gujarati writers and educators involved in the debate over social reforms, focusing on issues such as the status of women, child marriage, and the question of whether widows could remarry. He held Eastern civilisation in high esteem, and resisted the influence of Western civilisation, a position which drew him into conflicts with other social reformers of a less conservative outlook. He considered himself a "reformer along religious lines".
Manilal's writings belong to the Pandit Yuga, or "Scholar Era" – a time in which Gujarati writers explored their traditional literature, culture and religion in order to redefine contemporary Indian identity when it was subject to challenge from the influential Western model introduced under colonial rule. His works include Atmanimajjan, a collection of poems on the theme of love in the context of Advaita (non-duality) philosophy; Kanta, a play combining Sanskrit and English dramatic techniques; Nrusinhavatar, a play based on Sanskrit dramatic traditions; Pranavinimaya, a study of yoga and mysticism; and Siddhantasara, a historical critique of the world's religious philosophies. His faith in Shankara's Advaita philosophy provided the fundamental underpinning for his philosophical thought. He was invited to present a paper at the first Parliament of World Religions, held in Chicago in 1893, but financial considerations made his participation there impossible. (Full article...)
The Terri Schiavo case was a series of court and legislative actions in the United States from 1998 to 2005, regarding the care of Theresa Marie Schiavo (née Schindler) (/ˈʃaɪvoʊ/; December 3, 1963 – March 31, 2005), a woman in an irreversible persistent vegetative state. Schiavo's husband and legal guardian argued that Schiavo would not have wanted prolonged artificial life support without the prospect of recovery, and in 1998, he elected to remove her feeding tube. Schiavo's parents disputed her husband's assertions and challenged Schiavo's medical diagnosis, arguing in favor of continuing artificial nutrition and hydration. The highly publicized and prolonged series of legal challenges presented by her parents, which ultimately involved state and federal politicians up to the level of George W. Bush, the then U.S. president, caused a seven-year (1998 to 2005) delay before Schiavo's feeding tube was ultimately removed.
On February 25, 1990, at age 26, Schiavo went into cardiac arrest at her home in St. Petersburg, Florida. She was resuscitated, but had massive brain damage due to lack of oxygen to her brain and was left comatose. After two and a half months without improvement, her diagnosis was changed to that of a persistent vegetative state. For the next two years, doctors attempted occupational therapy, speech therapy, physical therapy and other experimental therapy, hoping to return her to a state of awareness, without success. In 1998, Schiavo's husband Michael Schiavo petitioned the Sixth Circuit Court of Florida to remove her feeding tube pursuant to Florida law. He was opposed by Terri's parents, Robert and Mary Schindler. The court determined that Schiavo would not have wished to continue life-prolonging measures, and on April 24, 2001, her feeding tube was removed for the first time, only to be reinserted several days later. On February 25, 2005, a Pinellas County judge again ordered the removal of Terri Schiavo's feeding tube. Several appeals and federal government intervention followed, which included Bush returning to Washington, D.C., to sign legislation moving the case to the federal courts. After appeals through the federal court system that upheld the original decision to remove the feeding tube, staff at the Pinellas Park hospice facility disconnected the feeding tube on March 18, 2005, and Schiavo died on March 31, 2005.

The essay posits that monotheism and the Enlightenment are based on "monomythical thinking", meaning that they only allow one story. It also posits that the separation of powers and the individual have their origin in polytheism, and argues that people should embrace what Marquard calls "enlightened polymythical thinking"—the recognition of several stories in the modern world. Marquard was a professor of philosophy and proponent of scepticism and pluralism. He belonged to a part of German philosophy that viewed the issues of modernity through political theology, which associates modern political concepts with theological concepts. Some of the points in the essay have precursors in the writings of Max Weber, Erik Peterson and Friedrich Nietzsche. (Full article...)

Gargi Vachaknavi (Sans: गार्गी वाचक्नवी (Devanagari); Gargi Vacaknavi (HK)), was an ancient Indian sage and philosopher. In Vedic literature, she is honoured as a great natural philosopher, renowned expounder of the Vedas, and known as Brahmavadini, a person with knowledge of Brahma Vidya. In the Sixth and the eighth Brahmana of Brihadaranyaka Upanishad, her name is prominent as she participates in the brahmayajna, a philosophic debate organized by King Janaka of Videha and she challenges the sage Yajnavalkya with perplexing questions on the issue of atman (soul). She is also said to have written many hymns in the Rigveda. She remained a celibate all her life and was held in veneration by the conventional Hindus.
Gargi, the daughter of sage Vachaknu in the lineage of sage Garga (c. 800-500 BCE) was named after her father Gargi Vachaknavi. From a young age, she evinced a keen interest in Vedic scriptures and became very proficient in fields of philosophy. She became highly knowledgeable in the Vedas and Upanishads in the Vedic times and held intellectual debates with other philosophers. (Full article...)

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

The argument from morality is an argument for the existence of God. Arguments from morality tend to be based on moral normativity or moral order. Arguments from moral normativity observe some aspect of morality and argue that God is the best or only explanation for this, concluding that God must exist. Arguments from moral order are based on the asserted need for moral order to exist in the universe. They claim that, for this moral order to exist, God must exist to support it. The argument from morality is noteworthy in that one cannot evaluate the soundness of the argument without attending to almost every important philosophical issue in meta-ethics.
German philosopher Immanuel Kant devised an argument from morality based on practical reason. Kant argued that the goal of humanity is to achieve perfect happiness and virtue (the summum bonum) and believed that an afterlife must be assumed to exist in order for this to be possible, and that God must be assumed to exist to provide this. Rather than aiming to prove the existence of God, however, Kant was simply attempting to demonstrate that all moral thought requires the assumption that God exists, and therefore that we are entitled to make such an assumption only as a regulative principle rather than a constitutive principle (meaning that such a principle can guide our actions, but it does not provide knowledge). In his book Mere Christianity, C. S. Lewis argued that "conscience reveals to us a moral law whose source cannot be found in the natural world, thus pointing to a supernatural Lawgiver." Lewis argued that accepting the validity of human reason as a given must include accepting the validity of practical reason, which could not be valid without reference to a higher cosmic moral order which could not exist without a God to create and/or establish it. A related argument is from conscience; John Henry Newman argued that the conscience supports the claim that objective moral truths exist because it drives people to act morally even when it is not in their own interest. Newman argued that, because the conscience suggests the existence of objective moral truths, God must exist to give authority to these truths. (Full article...)
Her works cover a broad range of topics, but she is best known for those dealing with the nature of power and evil, as well as politics, direct democracy, authority, and totalitarianism. She is also remembered for the controversy surrounding the trial of Adolf Eichmann, for her attempt to explain how ordinary people become actors in totalitarian systems, which was considered by some an apologia, and for the phrase "the banality of evil." Her name appears in the names of journals, schools, scholarly prizes, humanitarian prizes, think-tanks, on stamps, in street names, monuments, and is attached to other cultural and institutional markers that commemorate her thought.

Sun Tzu mastered the military science of ancient China and created the military doctrine of asymmetrical warfare. According to it, an attack on the enemy should begin only after the enemy has no opportunity to either defend or counterattack. It was used in the wars in the era of the Warring States in ancient China (about 475–221 BC). It's not the direct interpretation of the modern asymmetric military strategy. The ancient warriors used to call it the Victorious Methods of Warfare – Sheng Er Zhan Zhi, but it has the same meaning as the modern asymmetrical military strategy. The ancient professional warriors used it in individual combats against the enemies in the wars. As a result, a variety of armed and unarmed combat combinations have been created for various combat situations as the individual battle plans. Those combat combinations had specific names, descriptions and classifications. (Full article...)

Stoicism is a school of Hellenistic philosophy that flourished in Ancient Greece and Ancient Rome. The Stoics believed that the practice of virtue is enough to achieve eudaimonia: a well-lived life. The Stoics identified the path to achieving it with a life spent practicing the four virtues in everyday life: wisdom, courage, temperance or moderation, and justice, and living in accordance with nature. It was founded in the ancient Agora of Athens by Zeno of Citium around 300 BC.
Alongside Aristotle's ethics, the Stoic tradition forms one of the major founding approaches to virtue ethics. The Stoics are especially known for teaching that "virtue is the only good" for human beings, and that external things, such as health, wealth, and pleasure, are not good or bad in themselves (adiaphora) but have value as "material for virtue to act upon". Many Stoics—such as Seneca and Epictetus—emphasized that because "virtue is sufficient for happiness", a sage would be emotionally resilient to misfortune. The Stoics also held that certain destructive emotions resulted from errors of judgment, and they believed people should aim to maintain a will (called prohairesis) that is "in accordance with nature". Because of this, the Stoics thought the best indication of an individual's philosophy was not what a person said but how a person behaved. To live a good life, one had to understand the rules of the natural order since they believed everything was rooted in nature. (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?
