Philosophy (φιλοσοφία, 'love of wisdom', in Ancient Greek) is a systematic study of general and fundamental questions concerning topics like existence, reason, knowledge, value, mind, and language. It is a rational and critical inquiry that reflects on its own methods and assumptions.
Historically, many of the individual sciences, such as physics and psychology, formed part of philosophy. However, they are considered separate academic disciplines in the modern sense of the term. Influential traditions in the history of philosophy include Western, Arabic–Persian, Indian, and Chinese philosophy. Western philosophy originated in Ancient Greece and covers a wide area of philosophical subfields. A central topic in Arabic–Persian philosophy is the relation between reason and revelation. Indian philosophy combines the spiritual problem of how to reach enlightenment with the exploration of the nature of reality and the ways of arriving at knowledge. Chinese philosophy focuses principally on practical issues in relation to right social conduct, government, and self-cultivation.
Putnam applied equal scrutiny to his own philosophical positions as to those of others, subjecting each position to rigorous analysis until he exposed its flaws. As a result, he acquired a reputation for frequently changing his positions. In philosophy of mind, Putnam argued against the type-identity of mental and physical states based on his hypothesis of the multiple realizability of the mental, and for the concept of functionalism, an influential theory regarding the mind–body problem. In philosophy of language, along with Saul Kripke and others, he developed the causal theory of reference, and formulated an original theory of meaning, introducing the notion of semantic externalism based on a thought experiment called Twin Earth.

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...)

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

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...)
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.
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).

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...)
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...)
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...)

Anarky is a character 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 reflexions 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...)

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

The celestial spheres, or celestial orbs, were the fundamental entities of the cosmological models developed by Plato, Eudoxus, Aristotle, Ptolemy, Copernicus, and others. In these celestial models, the apparent motions of the fixed stars and planets are accounted for by treating them as embedded in rotating spheres made of an aetherial, transparent fifth element (quintessence), like gems set in orbs. Since it was believed that the fixed stars did not change their positions relative to one another, it was argued that they must be on the surface of a single starry sphere.
In modern thought, the orbits of the planets are viewed as the paths of those planets through mostly empty space. Ancient and medieval thinkers, however, considered the celestial orbs to be thick spheres of rarefied matter nested one within the other, each one in complete contact with the sphere above it and the sphere below. When scholars applied Ptolemy's epicycles, they presumed that each planetary sphere was exactly thick enough to accommodate them. By combining this nested sphere model with astronomical observations, scholars calculated what became generally accepted values at the time for the distances to the Sun: about 4 million miles (6.4 million kilometres), to the other planets, and to the edge of the universe: about 73 million miles (117 million kilometres). The nested sphere model's distances to the Sun and planets differ significantly from modern measurements of the distances, and the size of the universe is now known to be inconceivably large and continuously expanding.

New Age is a range of spiritual or religious practices and beliefs which rapidly grew in Western society during the early 1970s. Its highly eclectic and unsystematic structure makes a precise definition difficult. Although many scholars consider it a religious movement, its adherents typically see it as spiritual or as unifying Mind-Body-Spirit, and rarely use the term New Age themselves. Scholars often call it the New Age movement, although others contest this term and suggest it is better seen as a milieu or zeitgeist.
As a form of Western esotericism, the New Age drew heavily upon esoteric traditions such as the occultism of the eighteenth and nineteenth centuries, including the work of Emanuel Swedenborg and Franz Mesmer, as well as Spiritualism, New Thought, and Theosophy. More immediately, it arose from mid-twentieth century influences such as the UFO religions of the 1950s, the counterculture of the 1960s, and the Human Potential Movement. Its exact origins remain contested, but it became a major movement in the 1970s, at which time it was centered largely in the United Kingdom. It expanded widely in the 1980s and 1990s, in particular in the United States. By the start of the 21st century, the term New Age was increasingly rejected within this milieu, with some scholars arguing that the New Age phenomenon had ended. (Full article...)

Crime and Punishment (pre-reform Russian: Преступленіе и наказаніе; post-reform Russian: Преступление и наказание, tr.Prestupleniye i nakazaniye, IPA:[prʲɪstʊˈplʲenʲɪjeɪnəkɐˈzanʲɪje]) is a novel by the Russian author Fyodor Dostoevsky. It was first published in the literary journal The Russian Messenger in twelve monthly installments during 1866. It was later published in a single volume. It is the second of Dostoevsky's full-length novels following his return from ten years of exile in Siberia. Crime and Punishment is considered the first great novel of his mature period of writing and is often cited as one of the greatest works of world literature.
Crime and Punishment follows the mental anguish and moral dilemmas of Rodion Raskolnikov, an impoverished ex-student in Saint Petersburg who plans to kill an unscrupulous pawnbroker, an old woman who stores money and valuable objects in her flat. He theorises that with the money he could liberate himself from poverty and go on to perform great deeds, and seeks to convince himself that certain crimes are justifiable if they are committed in order to remove obstacles to the higher goals of 'extraordinary' men. Once the deed is done, however, he finds himself wracked with confusion, paranoia, and disgust. His theoretical justifications lose all their power as he struggles with guilt and horror and is confronted with both internal and external consequences of his deed. (Full article...)

Sallekhana (IAST: sallekhanā), also known as samlehna, santhara, samadhi-marana or sanyasana-marana, is a supplementary vow to the ethical code of conduct of Jainism. It is the religious practice of voluntarily fasting to death by gradually reducing the intake of food and liquids. It is viewed in Jainism as the thinning of human passions and the body, and another means of destroying rebirth-influencing karma by withdrawing all physical and mental activities. It is not considered a suicide by Jain scholars because it is not an act of passion, nor does it employ poisons or weapons. After the sallekhana vow, the ritual preparation and practice can extend into years.
Sallekhana is a vow available to both Jain ascetics and householders. Historic evidence such as nishidhi engravings suggest sallekhana was observed by both men and women, including queens, in Jain history. However, in the modern era, death through sallekhana has been a relatively uncommon event. (Full article...)
Although traces of anarchist ideas are found all throughout history, modern anarchism emerged from the Enlightenment. During the latter half of the 19th and the first decades of the 20th century, the anarchist movement flourished in most parts of the world and had a significant role in workers' struggles for emancipation. Various anarchist schools of thought formed during this period. Anarchists have taken part in several revolutions, most notably in the Paris Commune, the Russian Civil War and the Spanish Civil War, whose end marked the end of the classical era of anarchism. In the last decades of the 20th and into the 21st century, the anarchist movement has been resurgent once more, growing in popularity and influence within anti-capitalist, anti-war and anti-globalisation movements.

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 successfully 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.

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

Consolatio (Latin:[koːnsoːˈlaːtɪ.oː]; Consolation) is a lost philosophical work written by Marcus Tullius Cicero in the year 45 BC. The work had been written to soothe his grief after the death of his daughter, Tullia, which had occurred in February of the same year. Not much is known about the work, although it seems to have been inspired by the GreekphilosopherCrantor's ancient work De Luctu ("On Grief"), and its structure was probably similar to a series of letter correspondences between Servius Sulpicius Rufus and Cicero.
Fragments of the work survive, having been quoted by Lactantius, and Jerome makes note of the work in a consolatory letter to Heliodorus of Altino. A popular piece of writing until its loss, the Consolatio is widely accepted as the distinct work that transmitted the earlier consolatio literary tradition to the Romans of the late Republic. In 1583, Italian scholar Carlo Sigonio claimed to have discovered a non-fragmentary version of the Consolatio, although most scholars now agree that this work was a fake, with modern stylometric methods backing this up.

The history of Christian thought has included concepts of both inclusivity and exclusivity from its beginnings, that have been understood and applied differently in different ages, and have led to practices of both persecution and toleration. Early Christian thought established Christian identity, defined heresy, separated itself from polytheism and Judaism and developed the theological conviction called supersessionism. In the centuries after Christianity became the official religion of Rome, some scholars say Christianity became a persecuting religion. Others say the change to Christian leadership did not cause a persecution of pagans, and that what little violence occurred was primarily directed at non-orthodox Christians.
After the fall of the Roman Empire, Christian thought focused more on preservation than origination. This era of thought is exemplified by Gregory the Great, Saint Benedict, Visigothic Spain, illustrated manuscripts, and progress in medical care through monks. Although the roots of supersessionism and deicide can be traced to some second century Christian thought, Jews of the Middle Ages lived mostly peacefully alongside their Christian neighbors because of Augustine of Hippo's teaching that they should be left alone. In the Early Middle Ages, Christian thought on the military and involvement in war shifted to accommodate the crusades by inventing chivalry and new monastic orders dedicated to it. There was no single thread of Christian thought throughout most of the Middle Ages as the church was largely democratic and each order had its own doctrine. (Full article...)

The Indian Antiquary: A journal of oriental research in archaeology, history, literature, language, philosophy, religion, folklore, &c, &c (subtitle varies) was a journal of original research relating to India, published between 1872 and 1933. It was founded by the archaeologist James Burgess to enable the sharing of knowledge between scholars based in Europe and in India and was notable for the high quality of its epigraphic illustrations which enabled scholars to make accurate translations of texts that in many cases remain the definitive versions to this day. It was also pioneering in its recording of Indian folklore. It was succeeded by The New Indian Antiquary (1938–47) and the Indian Antiquary (1964–71). (Full article...)

Roman copy of a Hellenistic bust of Chrysippus (British Museum)
Chrysippus of Soli (/kraɪˈsɪpəs,krɪ-/; Greek: Χρύσιππος ὁ Σολεύς, Chrysippos ho Soleus; c. 279 –c. 206 BC) was a GreekStoicphilosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of the Stoic philosopher Cleanthes. When Cleanthes died, around 230 BC, Chrysippus became the third head of the Stoic school. A prolific writer, Chrysippus expanded the fundamental doctrines of Cleanthes' mentor Zeno of Citium, the founder and first head of the school, which earned him the title of the Second Founder of Stoicism.
Chrysippus excelled in logic, the theory of knowledge, ethics, and physics. He created an original system of propositional logic in order to better understand the workings of the universe and role of humanity within it. He adhered to a fatalistic view of fate, but nevertheless sought a role for personal agency in thought and action. Ethics, he thought, depended on understanding the nature of the universe, and he taught a therapy of extirpating the unruly passions which depress and crush the soul. He initiated the success of Stoicism as one of the most influential philosophical movements for centuries in the Greek and Roman world. The linguistic orientation of Chrysippus' work made it difficult for its students even within the Stoic school. (Full article...)
Hadley is known for his account of animal property rights theory. He proposes that wild animals be offered property rights over their territories, and that guardians be appointed to represent their interests in decision-making procedures. He suggests that this account could be justified directly, on the basis of the interests of the animals concerned, or indirectly, so that natural environments are protected. The theory has received discussion in popular and academic contexts, with critical responses from farming groups and mixed responses from moral and political theorists. (Full article...)
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...)

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?
