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.

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. Broad estimates of those who have an absence of belief in a god range from 500 million to 1.1 billion people worldwide. (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...)

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...)
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 first English edition of Part I
The Age of Reason; Being an Investigation of True and Fabulous Theology is a work by English and American political activist Thomas Paine, arguing for the philosophical position of deism. It follows in the tradition of 18th-century British deism, and challenges institutionalized religion and the legitimacy of the Bible. It was published in three parts in 1794, 1795, and 1807.
It was a best-seller in the United States, where it caused a deistic revival. British audiences, fearing increased political radicalism as a result of the French Revolution, received it with more hostility. The Age of Reason presents common deistic arguments; for example, it highlights what Paine saw as corruption of the Christian Church and criticizes its efforts to acquire political power. Paine advocates reason in the place of revelation, leading him to reject miracles and to view the Bible as an ordinary piece of literature, rather than a divinely-inspired text. In The Age of Reason, he promotes natural religion and argues for the existence of a creator god. (Full article...)

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

Why Marx Was Right is a 2011 non-fiction book by the British academic Terry Eagleton about the 19th-century philosopher Karl Marx and the schools of thought, collectively known as Marxism, that arose from his work. Written for laypeople, Why Marx Was Right outlines ten objections to Marxism that they may hold and aims to refute each one in turn. These include arguments that Marxism is irrelevant owing to changing social classes in the modern world, that it is deterministic and utopian, and that Marxists oppose all reforms and believe in an authoritarian state.
In his counterarguments, Eagleton explains how class struggle is central to Marxism, and that history is seen as a progression of modes of production, like feudalism and capitalism, involving the materials, technology and social relations required to produce goods and services within the society. Under a capitalist economy, the working class, known as the proletariat, are those lacking significant autonomy over their labour conditions, and have no control over the means of production. Eagleton describes how revolutions could lead to a new mode of production—socialism—in which the working class have control, and an eventual communist society could make the state obsolete. He explores the failures of the Soviet Union and other Marxist–Leninist countries. (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. 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...)

Eric Alfred Havelock (/ˈhævlɒk/; 3 June 1903 – 4 April 1988) was a British classicist who spent most of his life in Canada and the United States. He was a professor at the University of Toronto and was active in the Canadian socialist movement during the 1930s. In the 1960s and 1970s, he served as chair of the classics departments at both Harvard and Yale. Although he was trained in the turn-of-the-20th-century Oxbridge tradition of classical studies, which saw Greek intellectual history as an unbroken chain of related ideas, Havelock broke radically with his own teachers and proposed an entirely new model for understanding the classical world, based on a sharp division between literature of the 6th and 5th centuries BC on the one hand, and that of the 4th on the other.
Much of Havelock's work was devoted to addressing a single thesis: that all of Western thought is informed by a profound shift in the kinds of ideas available to the human mind at the point that Greek philosophy converted from an oral to a literate form. The idea has been controversial in classical studies, and has been rejected outright both by many of Havelock's contemporaries and modern classicists. Havelock and his ideas have nonetheless had far-reaching influence, both in classical studies and other academic areas. He and Walter J. Ong (who was himself strongly influenced by Havelock) essentially founded the field that studies transitions from orality to literacy, and Havelock has been one of the most frequently cited theorists in that field; as an account of communication, his work profoundly affected the media theories of Harold Innis and Marshall McLuhan. Havelock's influence has spread beyond the study of the classical world to that of analogous transitions in other times and places. (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...)

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...)
... that Chinese physician Yu Yan described theories like yinyang and the five phases as "simply all lies, absolutely not factual, and completely groundless"?
Determinism is the philosophical proposition that every event, including human cognition and action, is causally determined by an unbroken chain of prior occurrences. No mysterious miracles or wholly random events occur.
The principal consequence of deterministic philosophy is that free will (except as defined in strict compatibilism) becomes an illusion. It is a popular misconception that determinism necessarily entails that all future events have already been predetermined and will necessarily happen (a position known as Fatalism); this is not obviously the case, and the subject is still debated among metaphysicists. Determinism is associated with, and relies upon, the ideas of Materialism and Causality. Some of the philosophers who have dealt with this issue are Omar Khayyám, David Hume, Thomas Hobbes, Immanuel Kant, and, more recently, John Searle.
Pythagoras of Samos (Ancient Greek: Πυθαγόρας; c. 570 – c. 495 BC) was an ancient IonianGreek philosopher, polymath and the eponymous founder of Pythagoreanism. His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, the West in general. Knowledge of his life is clouded by legend; modern scholars disagree regarding Pythagoras's education and influences, but they do agree that, around 530 BC, he travelled to Croton in southern Italy, where he founded a school in which initiates were sworn to secrecy and lived a communal, ascetic lifestyle.
In antiquity, Pythagoras was credited with many mathematical and scientific discoveries, including the Pythagorean theorem, Pythagorean tuning, the five regular solids, the Theory of Proportions, the sphericity of the Earth, and the identity of the morning and evening stars as the planet Venus. It was said that he was the first man to call himself a philosopher ("lover of wisdom") and that he was the first to divide the globe into five climatic zones. Classical historians debate whether Pythagoras made these discoveries, and many of the accomplishments credited to him likely originated earlier or were made by his colleagues or successors. Some accounts mention that the philosophy associated with Pythagoras was related to mathematics and that numbers were important, but it is debated to what extent, if at all, he actually contributed to mathematics or natural philosophy.

Sermon of the Beatitudes depicts Jesus' Sermon on the Mount, in which he summarized his ethical teachings. James Tissot, c. 1890 Christian ethics, also known as moral theology, is a multi-faceted ethical system. It is a virtue ethic, which focuses on building moral character, and a deontological ethic which emphasizes duty. It also incorporates natural law ethics, which is built on the belief that it is the very nature of humans – created in the image of God and capable of morality, cooperation, rationality, discernment and so on – that informs how life should be lived, and that awareness of sin does not require special revelation. Other aspects of Christian ethics, represented by movements such as the social Gospel and liberation theology, may be combined into a fourth area sometimes called prophetic ethics.
Christian ethics derives its metaphysical core from the Bible, seeing God as the ultimate source of all power. Evidential, Reformed and volitionalepistemology are the three most common forms of Christian epistemology. The variety of ethical perspectives in the Bible has led to repeated disagreement over defining the basic Christian ethical principles, with at least seven major principles undergoing perennial debate and reinterpretation. Christian ethicists use reason, philosophy, natural law, the social sciences, and the Bible to formulate modern interpretations of those principles; Christian ethics applies to all areas of personal and societal ethics.

Rose Street as seen in an original sketch of 1851
The Rose Street Club (sometimes the International Rose Street Club and earlier the Local Rights Association for Rental and Sanitary Reform) was a far-left, anarchist organisation based in what is now Manette Street, London. Originally centred around London's German community, and acting as a meeting point for new immigrants, it became one of the leading radical clubs of Victorian London in the late-nineteenth century. Although its roots went back to the 1840s, it was properly formed in 1877 by members of a German émigré workers' education group, which soon became frequented by London radicals, and within a few years had led to the formation of similar clubs, sometimes in support and sometimes in rivalry. The Rose Street Club provided a platform for the radical speakers and agitators of the day and produced its own paper, Freiheit—which was distributed over Europe, and especially Germany—and pamphlets for other groups and individuals. Although radical, the club initially focused as much on providing a social service to its members as on activism. With the arrival of the anarchist Johann Most in London in the early 1880s, and his increasing influence within the club, it became increasingly aligned with anarchism. (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...)
Su Song was the engineer for a hydro-mechanicalastronomicalclock tower in medieval Kaifeng, which employed an early escapement mechanism. The escapement mechanism of Su's clock tower had been invented by Tang dynasty BuddhistmonkYi Xing and government official Liang Lingzan in 725 AD to operate a water-powered armillary sphere, although Su's armillary sphere was the first to be provided with a mechanical clock drive. Su's clock tower also featured the oldest known endless power-transmitting chain drive, called the tian ti (天梯), or "celestial ladder", as depicted in his horological treatise. The clock tower had 133 different clock jacks to indicate and sound the hours. Su Song's treatise about the clock tower, Xinyi Xiangfayao (新儀象法要), has survived since its written form in 1092 and official printed publication in 1094. The book has been analyzed by many historians, such as the British biochemist, historian, and sinologist Joseph Needham. The clock itself, however, was dismantled by the invadingJurchen army in 1127 AD, and although attempts were made to reassemble it, the tower was never successfully reinstated. (Full article...)
Fourteenth-century drawing of angels turning the celestial spheres
Ancient, medieval and Renaissance astronomers and philosophers developed many different theories about the dynamics of the celestial spheres. They explained the motions of the various nested spheres in terms of the materials of which they were made, external movers such as celestial intelligences, and internal movers such as motive souls or impressed forces. Most of these models were qualitative, although a few of them incorporated quantitative analyses that related speed, motive force and resistance. (Full article...)

Merit, demerit and its retributions at the level of the individual. Based on Spiro. Merit (Sanskrit: puṇya; Pali: puñña) is a concept considered fundamental to Buddhist ethics. It is a beneficial and protective force which accumulates as a result of good deeds, acts, or thoughts. Merit-making is important to Buddhist practice: merit brings good and agreeable results, determines the quality of the next life and contributes to a person's growth towards enlightenment. In addition, merit is also shared with a deceased loved one, in order to help the deceased in their new existence. Despite modernization, merit-making remains essential in traditional Buddhist countries and has had a significant impact on the rural economies in these countries.
Merit is connected with the notions of purity and goodness. Before Buddhism, merit was used with regard to ancestor worship, but in Buddhism it gained a more general ethical meaning. Merit is a force that results from good deeds done; it is capable of attracting good circumstances in a person's life, as well as improving the person's mind and inner well-being. Moreover, it affects the next lives to come, as well as the destination a person is reborn. The opposite of merit is demerit (papa), and it is believed that merit is able to weaken demerit. Indeed, merit has even been connected to the path to Nirvana itself, but many scholars say that this refers only to some types of merit. (Full article...)

The Upanishads (/ʊˈpʌnɪʃədz/; Sanskrit: उपनिषद्, IAST: Upaniṣad, pronounced[ˈʊpɐnɪʂɐd]) are late Vedic and post-Vedic Sanskrit texts that "document the transition from the archaic ritualism of the Veda into new religious ideas and institutions" and the emergence of the central religious concepts of Hinduism. They are the most recent addition to the Vedas, the oldest scriptures of Hinduism, and deal with meditation, philosophy, consciousness, and ontological knowledge. Earlier parts of the Vedas dealt with mantras, benedictions, rituals, ceremonies, and sacrifices.
While among the most important literature in the history of Indian religions and culture, the Upanishads document a wide variety of "rites, incantations, and esoteric knowledge" departing from Vedic ritualism and interpreted in various ways in the later commentarial traditions. The Upanishads are widely known, and their diverse ideas, interpreted in various ways, informed later traditions of Hinduism. The central concern of all Upanishads is to discover the relations between ritual, cosmic realities (including gods), and the human body/person, postulating Ātman and Brahman as the "summit of the hierarchically arranged and interconnected universe," but various ideas about the relation between Atman and Brahman can be found.

Portrait of Saint Augustine, the oldest proponent of the Divine command theory
Divine command theory (also known as theological voluntarism) is a meta-ethical theory which proposes that an action's status as morallygood is equivalent to whether it is commanded by God. The theory asserts that what is moral is determined by God's commands and that for a person to be moral he is to follow God's commands. Followers of both monotheistic and polytheistic religions in ancient and modern times have often accepted the importance of God's commands in establishing morality.
Numerous variants of the theory have been presented: historically, figures including Saint Augustine, Duns Scotus, William of Ockham and Søren Kierkegaard have presented various versions of divine command theory; more recently, Robert Merrihew Adams has proposed a "modified divine command theory" based on the omnibenevolence of God in which morality is linked to human conceptions of right and wrong. Paul Copan has argued in favour of the theory from a Christian viewpoint, and Linda Trinkaus Zagzebski's divine motivation theory proposes that God's motivations, rather than commands, are the source of morality.

Huygens first identified the correct laws of elastic collision in his work De Motu Corporum ex Percussione, completed in 1656 but published posthumously in 1703. In 1659, Huygens derived geometrically the formula in classical mechanics for the centrifugal force in his work De vi Centrifuga, a decade before Newton. In optics, he is best known for his wave theory of light, which he described in his Traité de la Lumière (1690). His theory of light was initially rejected in favour of Newton's corpuscular theory of light, until Augustin-Jean Fresnel adapted Huygens's principle to give a complete explanation of the rectilinear propagation and diffraction effects of light in 1821. Today this principle is known as the Huygens–Fresnel principle. (Full article...)

Vyāsatīrtha (c. 1460 – c. 1539), also called Vyasaraja or Chandrikacharya, was a Hinduphilosopher, 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...)

Feminism is a range of socio-political movements and ideologies that aim to define and establish the political, economic, personal, and social equality of the sexes. Feminism holds the position that modern societies are patriarchal—they prioritize the male point of view—and that women are treated unjustly in these societies. Efforts to change this include fighting against gender stereotypes and improving educational, professional, and interpersonal opportunities and outcomes for women.

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?
