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.
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. (Full article...)
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...)
The Fountainhead is a 1943 novel by Russian-American author
Ayn Rand, her first major literary success. The novel's protagonist, Howard Roark, is an intransigent young
architect who battles against conventional standards and refuses to compromise with an architectural establishment unwilling to accept innovation. Roark embodies what Rand believed to be the ideal man, and his struggle reflects Rand's belief that
individualism is superior to
collectivism.
Roark is opposed by what he calls "second-handers", who value conformity over independence and integrity. These include Roark's former classmate, Peter Keating, who succeeds by following popular styles but turns to Roark for help with design problems. Ellsworth Toohey, a
socialistarchitecture critic who uses his influence to promote his political and social agenda, tries to destroy Roark's career.
Tabloid newspaper publisher Gail Wynand seeks to shape popular opinion; he befriends Roark, then betrays him when public opinion turns in a direction he cannot control. The novel's most controversial character is Roark's lover, Dominique Francon. She believes that non-conformity has no chance of winning, so she alternates between helping Roark and working to undermine him. (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...)

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...)
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...)
Born and raised in
Albany, New York, Hand majored in philosophy at
Harvard College and graduated with honors from
Harvard Law School. After a relatively undistinguished career as a lawyer in Albany and New York City, he was appointed at the age of 37 as a
Manhattan federal district judge in 1909. The profession suited his detached and open-minded temperament, and his decisions soon won him a reputation for craftsmanship and authority. Between 1909 and 1914, under the influence of
Herbert Croly's social theories, Hand supported
New Nationalism. He ran unsuccessfully as the
Progressive Party's candidate for
chief judge of the
New York Court of Appeals in 1913, but withdrew from active politics shortly afterwards. In 1924, President
Calvin Coolidge elevated Hand to the Court of Appeals for the Second Circuit, which he went on to lead as the senior circuit judge (later retitled chief judge) from 1939 until his semi-retirement in 1951. Scholars have recognized the Second Circuit under Hand as one of the finest appeals courts in American history. Friends and admirers often lobbied for Hand's promotion to the Supreme Court, but circumstances and his political past conspired against his appointment. (Full article...)

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.
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...)

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 (at the time) personal relationships, received more attention than her writing. Wollstonecraft is regarded as one of the founding
feminist philosophers, and feminists often cite both her life and her works as important influences.
During her brief career she wrote novels, treatises, a
travel narrative, a history of the
French Revolution, a
conduct book, and a children's book. Wollstonecraft is best known for A Vindication of the Rights of Woman (1792), in which she argues that women are not naturally inferior to men but appear to be only because they lack education. She suggests that both men and women should be treated as rational beings and imagines a
social order founded on reason. (Full article...)
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). (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.
Confirmation bias (also confirmatory bias, myside bias, or congeniality bias) is the tendency to search for, interpret, favor, and recall information in a way that confirms or supports one's prior
beliefs or values. People display this bias when they select information that supports their views, ignoring contrary information, or when they interpret ambiguous evidence as supporting their existing attitudes. The effect is strongest for desired outcomes, for
emotionally charged issues, and for deeply entrenched beliefs.
Biased search for information, biased interpretation of this information, and biased memory recall, have been invoked to explain four specific effects:
attitude polarization (when a disagreement becomes more extreme even though the different parties are exposed to the same evidence)
belief perseverance (when beliefs persist after the evidence for them is shown to be false)
the irrational primacy effect (a greater reliance on information encountered early in a series)
illusory correlation (when people falsely perceive an association between two events or situations).
... that the book Working from Within details how
W. V. Quine only began to use the term "
naturalism" years after he had already developed the key tenets of the philosophy?
Natural selection is the differential survival and reproduction of individuals due to differences in
phenotype. It is a key mechanism of
evolution, the change in the
heritable traits characteristic of a
population over generations.
Charles Darwin popularised the term "natural selection", contrasting it with
artificial selection, which is intentional, whereas natural selection is not.
Variation of traits, both
genotypic and
phenotypic, exists within all populations of
organisms. However, some traits are more likely to facilitate
survival and
reproductive success. Thus, these traits are passed onto the next generation. These traits can also become more
common within a population if the environment that favours these traits remain fixed. If new traits become more favored due to changes in a specific
niche,
microevolution occurs. If new traits become more favored due to changes in the broader environment,
macroevolution occurs. Sometimes,
new species can arise especially if these new traits are radically different from the traits possessed by their predecessors. (Full article...)
Manilal Nabhubhai Dwivedi (pronounced[məɲilalnəbʰubʰaidvivedi]ⓘ; 26 September 1858 – 1 October 1898) was a
Gujarati-language writer, philosopher, and social thinker from
British India, commonly referred to as Manilal in literary circles. He was an influential figure in 19th-century
Gujarati literature, and was one of several Gujarati writers and educators involved in the debate over social reforms, focusing on issues such as the status of women, child marriage, and the question of whether widows could remarry. He held
Eastern civilisation in high esteem, and resisted the influence of
Western civilisation, a position which drew him into conflicts with other social reformers of a less conservative outlook. He considered himself a "reformer along religious lines".
Manilal's writings belong to the Pandit Yuga, or "Scholar Era" – a time in which Gujarati writers explored their traditional literature, culture and religion in order to redefine contemporary Indian identity when it was subject to challenge from the influential Western model introduced under
colonial rule. His works include Atmanimajjan, a collection of poems on the theme of love in the context of
Advaita (non-duality) philosophy; Kanta, a play combining
Sanskrit and English dramatic techniques; Nrusinhavatar, a play based on Sanskrit dramatic traditions; Pranavinimaya, a study of
yoga and
mysticism; and Siddhantasara, a historical critique of the world's religious philosophies. His faith in
Shankara's Advaita philosophy provided the fundamental underpinning for his philosophical thought. He was invited to present a paper at the first
Parliament of World Religions, held in
Chicago in 1893, but financial considerations made his participation there impossible. (Full article...)
Reich's work on character contributed to the development of
Anna Freud's The Ego and the Mechanisms of Defence (1936), and his idea of muscular armour—the expression of the personality in the way the body moves—shaped innovations such as
body psychotherapy,
Gestalt therapy,
bioenergetic analysis and
primal therapy. His writing influenced generations of intellectuals; he coined the phrase "the
sexual revolution" and according to one historian acted as its midwife. During the
1968 student uprisings in Paris and Berlin, students scrawled his name on walls and threw copies of The Mass Psychology of Fascism at police. (Full article...)
Varner started a research project in 2001 that looked at animals in Hare's two-level utilitarianism. The project's initial monograph, Personhood, Ethics, and Animal Cognition, was released by Oxford in 2012. In the book, Varner moved away from his biocentrism, instead endorsing a developed version of Hare's ethics. Varner draws a distinction between persons, near-persons and merely sentient beings; although all are morally considerable, the lives of persons are of the most significance, and the lives of merely sentient beings are of the least. The practical consequences of this view, though initial comments were offered in Personhood, Ethics, and Animal Cognition, was to be explored in Sustaining Animals, with which Varner at one time had a contract with Oxford. His third book was Defending Biodiversity: Environmental Science and Ethics, co-authored with Jonathan Newman and Stefan Linquist, and published with
Cambridge University Press. It was published in 2017. (Full article...)

Consciousness, at its simplest, is
awareness of internal and
externalexistence. However, its nature has led to millennia of analyses, explanations, and debate by
philosophers,
scientists, and
theologians. Opinions differ about what exactly needs to be studied or even considered consciousness. In some explanations, it is synonymous with the
mind, and at other times, an aspect of it. In the past, it was one's "inner life", the world of
introspection, of private
thought,
imagination, and
volition. Today, it often includes any kind of
cognition,
experience,
feeling, or
perception. It may be awareness, awareness of awareness,
metacognition, or
self-awareness, either continuously changing or not. The disparate range of research, notions and speculations raises a curiosity about whether the right questions are being asked.
Howard AdelmanCM (January 7, 1938 – July 23, 2023) was a Canadian philosopher and university professor. He retired as Professor Emeritus of Philosophy at
York University in 2003. Adelman was one of the founders of
Rochdale College, as well as the founder and director of York's Centre for Refugee Studies. He was editor of Refuge for ten years, and since his retirement he has received several honorary university and governmental appointments in Canada and abroad. Adelman was the recipient of numerous awards and grants, and presented the inaugural lecture in a series named in his honor at York University in 2008. (Full article...)
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...)

Sir William Blackstone (10 July 1723 – 14 February 1780) was an English
jurist,
justice and
Tory politician most noted for his Commentaries on the Laws of England, which became the best-known description of the doctrines of the English
common law. Born into a middle-class family in London, Blackstone was educated at
Charterhouse School before matriculating at
Pembroke College, Oxford, in 1738. After switching to and completing a
Bachelor of Civil Law degree, he was made a
fellow of
All Souls College, Oxford, on 2 November 1743, admitted to
Middle Temple, and
called to the Bar there in 1746. Following a slow start to his career as a barrister, Blackstone became heavily involved in university administration, becoming accountant, treasurer and bursar on 28 November 1746 and Senior Bursar in 1750. Blackstone is considered responsible for completing the Codrington Library and Warton Building, and simplifying the complex accounting system used by the college. On 3 July 1753 he formally gave up his practice as a barrister and instead embarked on a series of lectures on English law, the first of their kind. These were massively successful, earning him a total of £453 (£89,000 in 2023 terms), and led to the publication of An Analysis of the Laws of England in 1756, which repeatedly sold out and was used to preface his later works.
On 20 October 1759 Blackstone was confirmed as the first
Vinerian Professor of English Law, immediately embarking on another series of lectures and publishing a similarly successful second treatise, titled A Discourse on the Study of the Law. With his growing fame, he successfully returned to the bar and maintained a good practice, also securing election as
ToryMember of Parliament for the
rotten borough of
Hindon on 30 March 1761. In November 1765 he published the first of four volumes of Commentaries on the Laws of England, considered his magnum opus; the completed work earned Blackstone £14,000 (£2,459,000 in 2023 terms). After repeated failures, he successfully gained appointment to the judiciary as a justice of the
Court of King's Bench on 16 February 1770, leaving to replace
Edward Clive as a
justice of the Common Pleas on 25 June. He remained in this position until his death, on 14 February 1780. (Full article...)
Generally seen as a pioneering work of
zoology, Aristotle frames his text by explaining that he is investigating the what (the existing facts about animals) prior to establishing the why (the causes of these characteristics). The book is thus an attempt to apply philosophy to part of the
natural world. Throughout the work, Aristotle seeks to identify differences, both between individuals and between groups. A group is established when it is seen that all members have the same set of distinguishing features; for example, that all
birds have
feathers, wings, and beaks. This relationship between the birds and their features is recognized as a
universal. (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...)
The supreme God is Shiva, Shiva is Brahman, Brahman is Atman, Know your Atman, Know yourself to be that Brahman, states the Kaivalya Upanishad
The Kaivalya Upanishad (
Sanskrit: कैवल्य उपनिषद्) is an ancient
Sanskrit text and one of the minor Upanishads of
Hinduism. It is classified as a
Shaiva Upanishad, and survives into modern times in two versions, one attached to the
Krishna Yajurveda and other attached to the
Atharvaveda. It is, as an Upanishad, a part of the corpus of
Vedanta literature collection that presents the philosophical concepts of Hinduism.
The Upanishad extols
Shiva, aloneness and renunciation, describes the inner state of man in his personal spiritual journey detached from the world. The text is notable for presenting
Shaivism in Vedanta, discussing
Atman (Self) and its relation to
Brahman, and Self-knowledge as the path to kaivalya (liberation). (Full article...)

Philosophy ponders the most fundamental questions humankind has been able to ask. These are increasingly numerous and over time they have been arranged into the overlapping branches of the philosophy tree:
Aesthetics: What is art? What is beauty? Is there a standard of taste? Is art meaningful? If so, what does it mean? What is good art? Is art for the purpose of an end, or is "art for art's sake?" What connects us to art? How does art affect us? Is some art unethical? Can art corrupt or elevate societies?
Epistemology: What are the nature and limits of knowledge? What is more fundamental to human existence, knowing (epistemology) or being (ontology)? How do we come to know what we know? What are the limits and scope of knowledge? How can we know that there are other minds (if we can)? How can we know that there is an external world (if we can)? How can we prove our answers? What is a true statement?
Ethics: Is there a difference between ethically right and wrong actions (or values, or institutions)? If so, what is that difference? Which actions are right, and which wrong? Do divine commands make right acts right, or is their rightness based on something else? Are there standards of rightness that are absolute, or are all such standards relative to particular cultures? How should I live? What is happiness?
Logic: What makes a good argument? How can I think critically about complicated arguments? What makes for good thinking? When can I say that something just does not make sense? Where is the origin of logic?
Metaphysics: What sorts of things exist? What is the nature of those things? Do some things exist independently of our perception? What is the nature of space and time? What is the relationship of the mind to the body? What is it to be a person? What is it to be conscious? Do gods exist?
Political philosophy: Are political institutions and their exercise of power justified? What is justice? Is there a 'proper' role and scope of government? Is democracy the best form of governance? Is governance ethically justifiable? Should a state be allowed? Should a state be able to promote the norms and values of a certain moral or religious doctrine? Are states allowed to go to war? Do states have duties against inhabitants of other states?
