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.

In political philosophy, a throffer is a proposal (also called an intervention) that mixes an offer with a threat which will be carried out if the offer is not accepted. The term was first used in print by political philosopher Hillel Steiner; while other writers followed, it has not been universally adopted and it is sometimes considered synonymous with carrot and stick. Though the threatening aspect of a throffer need not be obvious, or even articulated at all, an overt example is: "Kill this man and receive £100; fail to kill him and I'll kill you."
Steiner differentiated offers, threats and throffers based on the preferability of compliance and noncompliance for the subject when compared to the normal course of events that would have come about were no intervention made. Steiner's account was criticised by philosopher Robert Stevens, who instead suggested that what was important in differentiating the kinds of intervention was whether performing or not performing the requested action was more or less preferable than it would have been were no intervention made. Throffers form part of the wider moral and political considerations of coercion, and form part of the question of the possibility of coercive offers. Contrary to received wisdom that only threats can be coercive, throffers lacking explicit threats have been cited as an example of coercive offers, while some writers argue that offers, threats and throffers may all be coercive if certain conditions are met. For others, by contrast, if a throffer is coercive, it is explicitly the threat aspect that makes it so, and not all throffers can be considered coercive. (Full article...)
Wallace did extensive fieldwork, starting in the Amazon River basin. He then did fieldwork in the Malay Archipelago, where he identified the faunal divide now termed the Wallace Line, which separates the Indonesian archipelago into two distinct parts: a western portion in which the animals are largely of Asian origin, and an eastern portion where the fauna reflect Australasia. He was considered the 19th century's leading expert on the geographical distribution of animal species, and is sometimes called the "father of biogeography", or more specifically of zoogeography.

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...)

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...)

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...)

Sir Bernard Arthur Owen WilliamsFBA (21 September 1929 – 10 June 2003) was an English moral philosopher. His publications include Problems of the Self (1973), Ethics and the Limits of Philosophy (1985), Shame and Necessity (1993), and Truth and Truthfulness (2002). He was knighted in 1999.
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.

Intelligent design (ID) is a pseudoscientific argument for the existence of God, presented by its proponents as "an evidence-based scientific theory about life's origins". Proponents claim that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." ID is a form of creationism that lacks empirical support and offers no testable or tenable hypotheses, and is therefore not science. The leading proponents of ID are associated with the Discovery Institute, a Christian, politically conservative think tank based in the United States.

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...)
Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. (Full article...)
In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the pole star and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancers' compasses in regard to declination).

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.

Anthropomorphism is the attribution of human characteristics and qualities to non-human beings, objects, natural, or supernatural phenomena. A form of personification (applying human or animal qualities to inanimate objects), anthropomorphism is similar to prosopopoeia (adopting the persona of another person). Animals, the forces of nature, and unseen or unknown authors of chance are frequent subjects of anthropomorphosis.
In religion and mythology, "anthropomorphism" refers to the perception of a divine being or beings in human form, or the recognition of human qualities generally, in these beings. Many mythologies are almost entirely concerned with anthropomorphic deities who express human characteristics such as jealousy, hatred, or love. The Greek gods such as Zeus and Apollo were often depicted in human form exhibiting both commendable and despicable human traits.

Eliminative materialism (also called eliminativism) is a materialist position in the philosophy of mind. It is the idea that the majority of mental states in folk psychology do not exist. Some supporters of eliminativism argue that no coherent neural basis will be found for many everyday psychological concepts such as belief or desire, since they are poorly defined. The argument is that psychological concepts of behavior and experience should be judged by how well they reduce to the biological level. Other versions entail the nonexistence of conscious mental states such as pain and visual perceptions.
Eliminativism about a class of entities is the view that the class of entities does not exist. For example, materialism tends to be eliminativist about the soul; modern chemists are eliminativist about phlogiston; modern biologists are eliminativist about élan vital; and modern physicists are eliminativist about luminiferous ether. Eliminative materialism is the relatively new (1960s–70s) idea that certain classes of mental entities that common sense takes for granted, such as beliefs, desires, and the subjective sensation of pain, do not exist. The most common versions are eliminativism about propositional attitudes, as expressed by Paul and Patricia Churchland, and eliminativism about qualia (subjective interpretations about particular instances of subjective experience), as expressed by Daniel Dennett, Georges Rey, and Jacy Reese Anthis.

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.
Hypatia (born c. 350–370 - March 415 AD) was a Neoplatonist philosopher, astronomer, and mathematician who lived in Alexandria, Egypt, then part of the Eastern Roman Empire. She was a prominent thinker in Alexandria where she taught philosophy and astronomy. Although preceded by Pandrosion, another Alexandrian female mathematician, she is the first female mathematician whose life is reasonably well recorded. Hypatia was renowned in her own lifetime as a great teacher and a wise counselor. She wrote a commentary on Diophantus's thirteen-volume Arithmetica, which may survive in part, having been interpolated into Diophantus's original text, and another commentary on Apollonius of Perga's treatise on conic sections, which has not survived. Many modern scholars also believe that Hypatia may have edited the surviving text of Ptolemy's Almagest, based on the title of her father Theon's commentary on Book III of the Almagest.
Hypatia constructed astrolabes and hydrometers, but did not invent either of these, which were both in use long before she was born. She was tolerant toward Christians and taught many Christian students, including Synesius, the future bishop of Ptolemais. Ancient sources record that Hypatia was widely beloved by pagans and Christians alike and that she established great influence with the political elite in Alexandria. Toward the end of her life, Hypatia advised Orestes, the Roman prefect of Alexandria, who was in the midst of a political feud with Cyril, the bishop of Alexandria. Rumors spread accusing her of preventing Orestes from reconciling with Cyril and, in March 415 AD, she was murdered by a mob of Christians led by a lector named Peter. (Full article...)
Kazi Nazrul Islam (Bengali: কাজী নজরুল ইসলাম, pronounced[kad͡ʒiˈnod͡ʒɾulislam]ⓘ; 24 May 1899 – 29 August 1976) was a Bangladeshi poet, short story writer, journalist, lyricist and musician. He is the national poet of Bangladesh. Nazrul produced a large body of poetry, music, messages, novels, and stories with themes, that included equality, justice, anti-imperialism, humanity, rebellion against oppression and religious devotion. Nazrul Islam's activism for political and social justice as well as writing a poem titled as "Bidrohī", meaning "the rebel" in Bengali, earned him the title of "Bidrohī Kôbi" (Rebel Poet). His compositions form the avant-garde music genre of Nazrul Gīti (Music of Nazrul).
Born into a Bengali MuslimKazi family hailing from Churulia in Burdwan district in Bengal Presidency (now in West Bengal, India), Nazrul Islam received religious education and as a young man worked as a muezzin at a local mosque. He learned about poetry, drama, and literature while working with the rural theatrical group Leṭor Dôl, Leṭo being a folk song genre of West Bengal usually performed by the people from Muslim community of the region. He joined the British Indian Army in 1917 and was posted in Karachi. Nazrul Islam established himself as a journalist in Calcutta after the war ended. He criticised the British Raj and called for revolution through his famous poetic works, such as "Bidrohī" ('The Rebel') and "Bhangar Gan" ('The Song of Destruction'), as well as in his publication Dhūmketu ('The Comet'). His nationalist activism in Indian independence movement led to his frequent imprisonment by the colonial British authorities. While in prison, Nazrul Islam wrote the "Rajbôndīr Jôbanbôndī" ('Deposition of a Political Prisoner'). His writings greatly inspired Bengalis of East Pakistan during the Bangladesh Liberation War.

Erode Venkatappa Ramasamy (17 September 1879 – 24 December 1973), revered by his followers as Periyar or Thanthai Periyar, was an Indian social activist and politician who started the Self-Respect Movement and Dravidar Kazhagam. He is known as the 'Father of the Dravidian movement'. He rebelled against Brahmin dominance and gender and caste inequality in Tamil Nadu. Since 2021, the Indian state of Tamil Nadu celebrates his birth anniversary as 'Social Justice Day'.
Ramasamy joined the Indian National Congress in 1919. In 1924, Ramasamy participated in non-violent agitation (satyagraha) involving Mahatma Gandhi in Vaikom, Travancore. He resigned from the Congress in 1925 when he felt that the party was only serving the interests of Brahmins. He questioned what he felt was the subjugation of non-Brahmin Dravidians as Brahmins enjoyed gifts and donations from non-Brahmins but opposed and discriminated against non-Brahmins in cultural and religious matters. He declared his stance to be "no god, no religion, no Gandhi, no Congress, and no Brahmins". (Full article...)

Title page of the original Danish edition from 1843
Either/Or (Danish: Enten – Eller) is the first published work of Danish philosopher Søren Kierkegaard. It appeared in two volumes in 1843 under the pseudonymous editorship of Victor Eremita (Latin for "victorious hermit"). It outlines a theory of human existence, marked by the distinction between an essentially hedonistic, aesthetic mode of life and the ethical life, which is predicated upon commitment.
Either/Or portrays two life views. Each life view is written and represented by a fictional author, with the prose reflecting and depending on the life view. The aesthetic life view is written in short essay form, with poetic imagery and allusions, discussing aesthetic topics such as music, seduction, drama, and beauty. The ethical life view is written as two long letters, with a more argumentative and restrained prose, discussing moral responsibility, critical reflection, and marriage. The views are expressed as experiences embodied by the fictional authors. The book's central concern is Aristotle's primal question, "How should we live?" His motto comes from Plutarch, "The deceived is wiser than one not deceived." (Full article...)
Once Latin translations of Averroes's works became available in the 13th century, this theory was taken up and expanded by Averroists in the Christian West, such as Siger of Brabant (c. 1240 – c. 1284), John of Jandun (c. 1285 – 1328) and John Baconthorpe (c. 1290 – 1347). It also influenced the secularist political philosophy of Dante Alighieri (c. 1265 – 1321) in the fourteenth century. However, it was rejected by other philosophers—including Thomas Aquinas (1225 – 1274), who wrote a detailed critique—and Averroes received condemnation from Catholic Church authorities.

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...)

Romanticism in Scotland was an artistic, literary and intellectual movement that developed between the late eighteenth and the early nineteenth centuries. It was part of the wider European Romantic movement, which was partly a reaction against the Age of Enlightenment, emphasising individual, national and emotional responses, moving beyond Renaissance and Classicist models, particularly into nostalgia for the Middle Ages. The concept of a separate national Scottish Romanticism was first articulated by the critics Ian Duncan and Murray Pittock in the Scottish Romanticism in World Literatures Conference held at UC Berkeley in 2006 and in the latter's Scottish and Irish Romanticism (2008), which argued for a national Romanticism based on the concepts of a distinct national public sphere and differentiated inflection of literary genres; the use of Scots language; the creation of a heroic national history through an Ossianic or Scottian 'taxonomy of glory' and the performance of a distinct national self in diaspora.
In the arts, Romanticism manifested itself in literature and drama in the adoption of the mythical bard Ossian, the exploration of national poetry in the work of Robert Burns and in the historical novels of Walter Scott. Scott also had a major impact on the development of a national Scottish drama. Art was heavily influenced by Ossian and a new view of the Highlands as the location of a wild and dramatic landscape. Scott profoundly affected architecture through his re-building of Abbotsford House in the early nineteenth century, which set off the boom in the Scots Baronial revival. In music, Burns was part of an attempt to produce a canon of Scottish song, which resulted in a cross fertilisation of Scottish and continental classical music, with romantic music becoming dominant in Scotland into the twentieth century.

Cochrane's work forms part of the political turn in animal ethics—that is, the emergence of academic literature exploring the normative aspects of human/nonhuman animal relationships from a political perspective. He is known for his interest-based account of animal rights, a theory of justice according to which animals have rights based on their possession of normatively-significant interests. The account is a two-tiered one, with individuals' strong interests grounding prima facie rights, and some prima facie rights becoming concrete, or all-things-considered, rights. In this picture, the violation of concrete rights, but not necessarily prima facie rights, represents an injustice. In particular, Cochrane argues that sentient animals' interests against suffering and death ground prima facie rights against the infliction of suffering and death. These prima facie rights convert to concrete rights in, for example, animal agriculture and animal testing, meaning that killing nonhuman animals or making them suffer for these purposes is unjust.

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?
