182-400: The humanities include the studies of philosophy , religion , history , language arts ( literature , writing , oratory , rhetoric , poetry , etc.), performing arts ( theater , music , dance , etc.), and visual arts ( painting , sculpture , photography , filmmaking , etc.). Some definitions of the humanities encompass law and religion due to their shared characteristics, such as

364-425: A linguistic therapy. According to Ludwig Wittgenstein , for instance, philosophy aims at dispelling misunderstandings to which humans are susceptible due to the confusing structure of ordinary language . Phenomenologists , such as Edmund Husserl , characterize philosophy as a "rigorous science" investigating essences . They practice a radical suspension of theoretical assumptions about reality to get back to

546-415: A multi-layered network of cooperating, distinct, or even competing social groups – from families and peer groups to corporations and political states . As such, social interactions between humans have established a wide variety of values, social norms , languages , and traditions (collectively termed institutions ), each of which bolsters human society . Humans are also highly curious , with

728-528: A social science or a humanities discipline, depending on one's perspective. Some see it as a social science because of its objective and measurable nature, while others view it as a humanities discipline because of its focus on values and interpretation. Law is not always enforceable, especially in the international relations context. Law has been defined in various ways, such as "a system of rules", "an interpretive concept" for achieving justice, "an authority" to mediate between people's interests, or "the command of

910-668: A theory of mind . The human mind is capable of introspection , private thought , imagination , volition , and forming views on existence . This has allowed great technological advancements and complex tool development through complex reasoning and the transmission of knowledge to subsequent generations through language . Humans have had a dramatic effect on the environment . They are apex predators , being rarely preyed upon by other species. Human population growth , industrialization, land development, overconsumption and combustion of fossil fuels have led to environmental destruction and pollution that significantly contributes to

1092-443: A consequence of better nutrition, healthcare, and living conditions. The average mass of an adult human is 59 kg (130 lb) for females and 77 kg (170 lb) for males. Like many other conditions, body weight and body type are influenced by both genetic susceptibility and environment and varies greatly among individuals. Humans have a far faster and more accurate throw than other animals. Humans are also among

1274-486: A degree in the humanities. By 2010, this figure had risen to 2.6%. This represents a doubling of the number of Americans with degrees in the humanities over a 60-year period. The increase in the number of Americans with humanities degrees is in part due to the overall rise in college enrollment in the United States. In 1940, 4.6% of Americans had a four-year degree, but by 2016, this figure had risen to 33.4%. This means that

1456-545: A doctor diagnoses a disease based on the observed symptoms. Logic also investigates incorrect forms of reasoning. They are called fallacies and are divided into formal and informal fallacies based on whether the source of the error lies only in the form of the argument or also in its content and context. Metaphysics is the study of the most general features of reality , such as existence, objects and their properties , wholes and their parts , space and time , events , and causation . There are disagreements about

1638-419: A few other places), saw the emergence of agriculture and permanent human settlement ; in turn, this led to the development of civilization and kickstarted a period of continuous (and ongoing) population growth and rapid technological change . Since then, a number of civilizations have risen and fallen, while a number of sociocultural and technological developments have resulted in significant changes to

1820-587: A field called the digital humanities . Philosophy 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

2002-463: A great capacity for altering their habitats by means of technology, irrigation , urban planning , construction, deforestation and desertification . Human settlements continue to be vulnerable to natural disasters , especially those placed in hazardous locations and with low quality of construction. Grouping and deliberate habitat alteration is often done with the goals of providing protection, accumulating comforts or material wealth, expanding

2184-444: A great variety of methods to arrive at philosophical knowledge. They include conceptual analysis , reliance on common sense and intuitions , use of thought experiments , analysis of ordinary language , description of experience , and critical questioning . Philosophy is related to many other fields, including the sciences, mathematics , business , law , and journalism . It provides an interdisciplinary perspective and studies

2366-612: A higher body fat percentage. At puberty , humans develop secondary sex characteristics . Females are capable of pregnancy , usually between puberty, at around 12 years old, and menopause , around the age of 50. As omnivorous creatures, they are capable of consuming a wide variety of plant and animal material, and have used fire and other forms of heat to prepare and cook food since the time of Homo erectus . Humans can survive for up to eight weeks without food and several days without water . Humans are generally diurnal , sleeping on average seven to nine hours per day. Childbirth

2548-475: A human can lose personhood (such as by going into a persistent vegetative state ). Humans are apes ( superfamily Hominoidea ). The lineage of apes that eventually gave rise to humans first split from gibbons (family Hylobatidae) and orangutans (genus Pongo ), then gorillas (genus Gorilla ), and finally, chimpanzees and bonobos (genus Pan ). The last split, between the human and chimpanzee–bonobo lineages, took place around 8–4 million years ago, in

2730-697: A metaphysical foundation of ethics. The modern period in Chinese philosophy began in the early 20th century and was shaped by the influence of and reactions to Western philosophy. The emergence of Chinese Marxism —which focused on class struggle , socialism , and communism —resulted in a significant transformation of the political landscape. Another development was the emergence of New Confucianism , which aims to modernize and rethink Confucian teachings to explore their compatibility with democratic ideals and modern science. Traditional Japanese philosophy assimilated and synthesized ideas from different traditions, including

2912-581: A more barrel-shaped chests in contrast to the funnel shape of other apes, an adaptation for bipedal respiration. Apart from bipedalism and brain size, humans differ from chimpanzees mostly in smelling , hearing and digesting proteins . While humans have a density of hair follicles comparable to other apes, it is predominantly vellus hair , most of which is so short and wispy as to be practically invisible. Humans have about 2 million sweat glands spread over their entire bodies, many more than chimpanzees, whose sweat glands are scarce and are mainly located on

3094-499: A much clearer picture of life at the time. Between the 8th and 6th century BCE, Europe entered the classical antiquity age, a period when ancient Greece and ancient Rome flourished. Around this time other civilizations also came to prominence. The Maya civilization started to build cities and create complex calendars . In Africa, the Kingdom of Aksum overtook the declining Kingdom of Kush and facilitated trade between India and

3276-461: A mutual contempt for one another, the former looking down on the latter as unscientific, the latter regarding the former as philistine . […] The difference comes down to the fact that social science really wants to be predictive, meaning that man is predictable, while the humanities say that he is not. For many decades, there has been a growing public perception that a humanities education inadequately prepares graduates for employment. The common belief

3458-463: A noticeable growth in the number of female philosophers , but they still remained underrepresented. Arabic–Persian philosophy arose in the early 9th century CE as a response to discussions in the Islamic theological tradition . Its classical period lasted until the 12th century CE and was strongly influenced by ancient Greek philosophers. It employed their ideas to elaborate and interpret the teachings of

3640-460: A part of intellectual history , but it also investigates questions not covered by intellectual history such as whether the theories of past philosophers are true and have remained philosophically relevant. The history of philosophy is primarily concerned with theories based on rational inquiry and argumentation; some historians understand it in a looser sense that includes myths , religious teachings , and proverbial lore. Influential traditions in

3822-433: A particular path. In the liberal arts tradition, musicology is also used to broaden skills of non-musicians by teaching skills, including concentration and listening. Theatre (or theater) (Greek "theatron", θέατρον ) is the branch of the performing arts concerned with acting out stories in front of an audience using combinations of speech, gesture, music, dance, sound and spectacle — indeed any one or more elements of

A characteristic of this style is that the local colour is often defined by an outline (a contemporary equivalent is the cartoon). This is evident in, for example, the art of India, Tibet and Japan. Religious Islamic art forbids iconography, and expresses religious ideas through geometry instead. The physical and rational certainties depicted by

4186-447: A result, humans are a cosmopolitan species found in almost all regions of the world, including tropical rainforest , arid desert , extremely cold arctic regions , and heavily polluted cities; in comparison, most other species are confined to a few geographical areas by their limited adaptability. The human population is not, however, uniformly distributed on the Earth 's surface, because

4368-632: A similar species. Migrating out of Africa , they gradually replaced and interbred with local populations of archaic humans. Multiple hypotheses for the extinction of archaic human species such as Neanderthals include competition, violence , interbreeding with Homo sapiens , or inability to adapt to climate change . Humans began exhibiting behavioral modernity about 160,000–60,000 years ago. For most of their history, humans were nomadic hunter-gatherers. The Neolithic Revolution , which began in Southwest Asia around 13,000 years ago (and separately in

4550-515: A simple linear or branched progression but involved interbreeding between related species . Genomic research has shown that hybridization between substantially diverged lineages was common in human evolution. DNA evidence suggests that several genes of Neanderthal origin are present among all non sub-Saharan-African populations, and Neanderthals and other hominins, such as Denisovans , may have contributed up to 6% of their genome to present-day non sub-Saharan-African humans. Human evolution

4732-589: A source of reliable benchmarks to guide analysis of the state of the humanities in the United States. The 1980 United States Rockefeller Commission on the Humanities described the humanities in its report "The Humanities in American Life": Through the humanities we reflect on the fundamental question: What does it mean to be human? The humanities offer clues but never a complete answer. They reveal how people have tried to make moral, spiritual, and intellectual sense of

4914-574: A sovereign" backed by the threat of punishment. However one likes to think of law, it is a completely central social institution. Legal policy is shaped by the practical application of ideas from many social science and humanities disciplines, including philosophy, history, political science, economics, anthropology, and sociology. Law is politics , because politicians create them. Law is philosophy , because moral and ethical persuasions shape their ideas. Law tells many of history 's stories, because statutes, case law and codifications build up over time. Law

5096-451: A successful labor increased significantly during the 20th century in wealthier countries with the advent of new medical technologies. In contrast, pregnancy and natural childbirth remain hazardous ordeals in developing regions of the world, with maternal death rates approximately 100 times greater than in developed countries. Both the mother and the father provide care for human offspring, in contrast to other primates, where parental care

5278-481: A surface by applying pressure from a tool, or moving a tool across a surface. Common tools are graphite pencils , pen and ink , inked brushes , wax color pencils , crayons , charcoals , pastels , and markers . Digital tools that simulate the effects of these are also used. The main techniques used in drawing are: line drawing, hatching , crosshatching, random hatching, scribbling, stippling , and blending. A computer aided designer who excels in technical drawing

5460-589: A universally accepted definition, but which has variably included all written work; writing that possesses literary merit; and language that emphasizes its own literary features, as opposed to ordinary language . Etymologically the term derives from the Latin word literatura /litteratura which means "writing formed with letters", although some definitions include spoken or sung texts . Literature can be classified as fiction or non-fiction ; poetry or prose . It can be further distinguished according to major forms such as

5642-612: A variety of arguments. Deductive arguments are mainly studied by formal logic. An argument is deductively valid if the truth of its premises ensures the truth of its conclusion. Deductively valid arguments follow a rule of inference , like modus ponens , which has the following logical form : " p ; if p then q ; therefore q ". An example is the argument "today is Sunday; if today is Sunday then I don't have to go to work today; therefore I don't have to go to work today". The premises of non-deductive arguments also support their conclusion, although this support does not guarantee that

Definitions of what constitutes dance are dependent on social , cultural , aesthetic , artistic , and moral constraints and range from functional movement (such as Folk dance ) to codified, virtuoso techniques such as ballet . The great traditions in art have a foundation in the art of one of the ancient civilizations, such as Ancient Japan , Greece and Rome , China , India , Greater Nepal , Mesopotamia and Mesoamerica . Ancient Greek art saw

6006-519: A veneration of the human physical form and the development of equivalent skills to show musculature, poise, beauty and anatomically correct proportions. Ancient Roman art depicted gods as idealized humans, shown with characteristic distinguishing features (e.g., Zeus ' thunderbolt). The emphasis on spiritual and religious themes in Byzantine and Gothic art of the Middle Ages reflected the dominance of

6188-406: A wide variety of plant and animal material. Human groups have adopted a range of diets from purely vegan to primarily carnivorous . In some cases, dietary restrictions in humans can lead to deficiency diseases ; however, stable human groups have adapted to many dietary patterns through both genetic specialization and cultural conventions to use nutritionally balanced food sources. The human diet

6370-549: A world where irrationality, despair, loneliness, and death are as conspicuous as birth, friendship, hope, and reason. The Commission on the Humanities and Social Sciences 2013 report "The Heart of the Matter" supports the notion of a broad " liberal arts education ", which includes study in disciplines from the natural sciences to the arts as well as the humanities. Many colleges provide such an education; some require it. The University of Chicago and Columbia University were among

Embryonic development in the human covers the first eight weeks of development; at the beginning of the ninth week the embryo is termed a fetus . Humans are able to induce early labor or perform a caesarean section if the child needs to be born earlier for medical reasons. In developed countries, infants are typically 3–4 kg (7–9 lb) in weight and 47–53 cm (19–21 in) in height at birth. However, low birth weight

6734-489: Is a combination of different parts and attempts to identify what those parts are. An influential theory in this area claims that knowledge has three components: it is a belief that is justified and true . This theory is controversial and the difficulties associated with it are known as the Gettier problem . Alternative views state that knowledge requires additional components, like the absence of luck; different components, like

6916-510: Is a common issue in relation to the sources of knowledge and the justification they offer. It is based on the idea that beliefs require some kind of reason or evidence to be justified. The problem is that the source of justification may itself be in need of another source of justification. This leads to an infinite regress or circular reasoning . Foundationalists avoid this conclusion by arguing that some sources can provide justification without requiring justification themselves. Another solution

7098-485: Is a mixture of the two parental sets. Among the 23 pairs of chromosomes, there are 22 pairs of autosomes and one pair of sex chromosomes . Like other mammals, humans have an XY sex-determination system , so that females have the sex chromosomes XX and males have XY. Genes and environment influence human biological variation in visible characteristics, physiology, disease susceptibility and mental abilities. The exact influence of genes and environment on certain traits

7280-424: Is a population decline in the winter months of this realm. Humans established nation-states in the other seven realms, such as South Africa , India , Russia , Australia , Fiji , United States and Brazil (each located in a different biogeographical realm). By using advanced tools and clothing , humans have been able to extend their tolerance to a wide variety of temperatures, humidities , and altitudes. As

7462-561: Is a set of essential features shared by all parts of philosophy. Others see only weaker family resemblances or contend that it is merely an empty blanket term. Precise definitions are often only accepted by theorists belonging to a certain philosophical movement and are revisionistic according to Søren Overgaard et al. in that many presumed parts of philosophy would not deserve the title "philosophy" if they were true. Some definitions characterize philosophy in relation to its method, like pure reasoning. Others focus on its topic, for example, as

7644-636: Is also a specialized form of fine art in which the artists perform their work live to an audience. This is called Performance art . Most performance art also involves some form of plastic art, perhaps in the creation of props . Dance was often referred to as a plastic art during the Modern dance era. Musicology as an academic discipline can take a number of different paths, including historical musicology , music literature, ethnomusicology and music theory . Undergraduate music majors generally take courses in all of these areas, while graduate students focus on

7826-467: Is also concerned with the moral evaluation of character traits and institutions. It explores what the standards of morality are and how to live a good life. Philosophical ethics addresses such basic questions as "Are moral obligations relative?"; "Which has priority: well-being or obligation?"; and "What gives life meaning?" The main branches of ethics are meta-ethics , normative ethics , and applied ethics . Meta-ethics asks abstract questions about

8008-515: Is also economics, because any rule about contract , tort , property law , labour law , company law and many more can have long-lasting effects on how productivity is organised and the distribution of wealth. The noun law derives from the Old English word lagu , meaning something laid down or fixed, and the adjective legal comes from the Latin word LEX . Literature is a term that does not have

8190-529: Is also used to describe methods of non-verbal communication (see body language ) between humans or animals ( bee dance , mating dance), and motion in inanimate objects ( the leaves danced in the wind ). Choreography is the process of creating dances, and the people who create choreography are known as choreographers. Choreographers use movement, music , and other elements to create expressive and artistic dances. They may work alone or with other artists to create new works, and their work can be presented in

8372-479: Is an expression of the philosopher's love of wisdom and has the aim of improving one's well-being by leading a reflective life. For example, the Stoics saw philosophy as an exercise to train the mind and thereby achieve eudaimonia and flourish in life. As a discipline, the history of philosophy aims to provide a systematic and chronological exposition of philosophical concepts and doctrines. Some theorists see it as

8554-402: Is characterized by a number of morphological , developmental , physiological , and behavioral changes that have taken place since the split between the last common ancestor of humans and chimpanzees . The most significant of these adaptations are hairlessness , obligate bipedalism, increased brain size and decreased sexual dimorphism ( neoteny ). The relationship between all these changes

8736-451: Is closely related to the disciplines of logic and linguistics. The philosophy of language rose to particular prominence in the early 20th century in analytic philosophy due to the works of Frege and Russell. One of its central topics is to understand how sentences get their meaning. There are two broad theoretical camps: those emphasizing the formal truth conditions of sentences and those investigating circumstances that determine when it

8918-456: Is common in developing countries, and contributes to the high levels of infant mortality in these regions. Compared with other species, human childbirth is dangerous, with a much higher risk of complications and death. The size of the fetus's head is more closely matched to the pelvis than in other primates. The reason for this is not completely understood, but it contributes to a painful labor that can last 24 hours or more. The chances of

9100-404: Is commonly regarded as a social science . Based on current knowledge, it seems that all known cultures, both in the past and present, have some form of belief system or religious practice. While there may be isolated individuals or groups who do not practice any form of religion, it is not known if there has ever been a society that was entirely devoid of religious belief. The definition of religion

9282-408: Is concerned with meaning , understanding , or the clarification of language. According to one view, philosophy is conceptual analysis , which involves finding the necessary and sufficient conditions for the application of concepts. Another definition characterizes philosophy as thinking about thinking to emphasize its self-critical, reflective nature. A further approach presents philosophy as

9464-469: Is cut or shaved down to the desired form, like stone and wood. In the West, the history of the humanities can be traced to ancient Greece, as the basis of a broad education for citizens. During Roman times, the concept of the seven liberal arts evolved, involving grammar , rhetoric and logic (the trivium ), along with arithmetic , geometry , astronomy and music (the quadrivium ). These subjects formed

9646-421: Is dangerous, with a high risk of complications and death . Often, both the mother and the father provide care for their children, who are helpless at birth . Humans have a large, highly developed, and complex prefrontal cortex , the region of the brain associated with higher cognition. Humans are highly intelligent and capable of episodic memory ; they have flexible facial expressions, self-awareness , and

9828-402: Is distinguished from other ways of addressing these issues by its critical, generally systematic approach and its reliance on reasoned argument, rather than experiments ( experimental philosophy being an exception). Philosophy used to be a very comprehensive term, including what have subsequently become separate disciplines, such as physics . (As Immanuel Kant noted, "Ancient Greek philosophy

10010-472: Is generally aging, with the median age around 40 years. In the developing world , the median age is between 15 and 20 years. While one in five Europeans is 60 years of age or older, only one in twenty Africans is 60 years of age or older. In 2012, the United Nations estimated that there were 316,600 living centenarians (humans of age 100 or older) worldwide. Humans are omnivorous , capable of consuming

10192-443: Is inherited only from the mother, geneticists have concluded that the last female common ancestor whose genetic marker is found in all modern humans, the so-called mitochondrial Eve , must have lived around 90,000 to 200,000 years ago. Most human reproduction takes place by internal fertilization via sexual intercourse , but can also occur through assisted reproductive technology procedures. The average gestation period

10374-408: Is itself a borrowing from the Latin philosophia . The term philosophy acquired the meanings of "advanced study of the speculative subjects ( logic , ethics , physics , and metaphysics )", "deep wisdom consisting of love of truth and virtuous living", "profound learning as transmitted by the ancient writers", and "the study of the fundamental nature of knowledge , reality , and existence , and

10556-408: Is mostly done by the mother. Helpless at birth , humans continue to grow for some years, typically reaching sexual maturity at 15 to 17 years of age. The human life span has been split into various stages ranging from three to twelve. Common stages include infancy , childhood , adolescence , adulthood and old age . The lengths of these stages have varied across cultures and time periods but

Modern artists have extended the practice of painting considerably to include, for example, collage . This began with cubism and is not painting in strict sense. Some modern painters incorporate different materials such as sand , cement , straw or wood for their texture. Examples of these are

Humanities majors are sought after in many areas of business, specifically for their critical thinking and problem-solving skills. While often considered "soft skills", humanities majors gain skills such as "include persuasive written and oral communication, creative problem-solving, teamwork, decision-making, self-management, and critical analysis".

Rituals are used to bound the community together. Social animals require rules. Ethics is a requirement of society, but not a requirement of religion. Shinto, Daoism, and other folk or natural religions do not have ethical codes. While some religions do include

This makes them more homogeneous than other great apes, including chimpanzees. This small variation in human DNA compared to many other species suggests a population bottleneck during the Late Pleistocene (around 100,000 years ago), in which

11466-475: Is presented by coherentists , who state that a belief is justified if it coheres with other beliefs of the person. Many discussions in epistemology touch on the topic of philosophical skepticism , which raises doubts about some or all claims to knowledge. These doubts are often based on the idea that knowledge requires absolute certainty and that humans are unable to acquire it. Ethics, also known as moral philosophy, studies what constitutes right conduct . It

11648-415: Is referred to as a draftsman or draughtsman . Literally, painting is the practice of applying pigment suspended in a carrier (or medium ) and a binding agent (a glue ) to a surface (support) such as paper , canvas or a wall. However, when used in an artistic sense, it means the use of this activity in combination with drawing , composition and other aesthetic considerations in order to manifest

Quine , philosophy is an empirical yet abstract science that is concerned with wide-ranging empirical patterns instead of particular observations. Science-based definitions usually face the problem of explaining why philosophy in its long history has not progressed to the same extent or in

Human Humans ( Homo sapiens , meaning "thinking man" or "wise man") or modern humans are the most common and widespread species of primate , and the last surviving species of the genus Homo . They are great apes characterized by their hairlessness , bipedalism , and high intelligence . Humans have large brains , enabling more advanced cognitive skills that enable them to thrive and adapt in varied environments, develop highly complex tools , and form complex social structures and civilizations . Humans are highly social , with individual humans tending to belong to

According to this view, actions should conform to what an ideally virtuous agent would do by manifesting virtues like generosity and honesty . Logic is the study of correct reasoning . It aims to understand how to distinguish good from bad arguments . It

12376-474: Is that graduates from such programs face underemployment and that incomes are too low for a humanities education to be worth the investment. Humanities graduates find employment in a wide variety of management and professional occupations. In Britain, for example, over 11,000 humanities majors found employment in the following occupations: Many humanities graduates may find themselves with no specific career goals upon graduation, which can lead to lower incomes in

12558-468: Is the 1687 book Philosophiæ Naturalis Principia Mathematica by Isaac Newton . This book referred to natural philosophy in its title, but it is today considered a book of physics. The meaning of philosophy changed toward the end of the modern period when it acquired the more narrow meaning common today. In this new sense, the term is mainly associated with philosophical disciplines like metaphysics, epistemology, and ethics. Among other topics, it covers

Metaphysics examines the most general features of reality , existence, objects , and properties . Other subfields are aesthetics , philosophy of language , philosophy of mind , philosophy of religion , philosophy of science , philosophy of mathematics , philosophy of history , and political philosophy . Within each branch, there are competing schools of philosophy that promote different principles, theories, or methods. Philosophers use

Epistemology is primarily interested in declarative knowledge or knowledge of facts, like knowing that Princess Diana died in 1997. But it also investigates practical knowledge , such as knowing how to ride a bicycle, and knowledge by acquaintance , for example, knowing a celebrity personally. One area in epistemology is the analysis of knowledge . It assumes that declarative knowledge

13286-654: Is typified by an unusually rapid growth spurt during adolescence. Human females undergo menopause and become infertile at around the age of 50. It has been proposed that menopause increases a woman's overall reproductive success by allowing her to invest more time and resources in her existing offspring, and in turn their children (the grandmother hypothesis ), rather than by continuing to bear children into old age. The life span of an individual depends on two major factors, genetics and lifestyle choices. For various reasons, including biological/genetic causes, women live on average about four years longer than men. As of 2018 ,

13468-456: Is usually divided into formal and informal logic . Formal logic uses artificial languages with a precise symbolic representation to investigate arguments. In its search for exact criteria, it examines the structure of arguments to determine whether they are correct or incorrect. Informal logic uses non-formal criteria and standards to assess the correctness of arguments. It relies on additional factors such as content and context. Logic examines

Further topics include the essence of works of art and the processes involved in creating them. The philosophy of language studies the nature and function of language . It examines the concepts of meaning , reference , and truth. It aims to answer questions such as how words are related to things and how language affects human thought and understanding. It

When traditional religions fail to address new concerns, then new religions will emerge. The performing arts differ from the visual arts in that the former uses the artist's own body, face, and presence as a medium, and the latter uses materials such as clay, metal, or paint, which can be molded or transformed to create some art object . Performing arts include acrobatics , busking , comedy , dance , film , magic , music , opera , juggling , marching arts , such as brass bands , and theatre . Artists who participate in these arts in front of an audience are called performers, including actors, comedians , dancers , musicians , and singers . Performing arts are also supported by workers in related fields, such as songwriting and stagecraft . Performers often adapt their appearance , such as with costumes and stage makeup , etc. There

14196-534: The British Empire expanded to become the world's largest empire . A tenuous balance of power among European nations collapsed in 1914 with the outbreak of the First World War , one of the deadliest conflicts in history. In the 1930s, a worldwide economic crisis led to the rise of authoritarian regimes and a Second World War , involving almost all of the world's countries . The war's destruction led to

14378-568: The Caral–Supe civilization is the oldest complex civilization in the Americas. Astronomy and mathematics were also developed and the Great Pyramid of Giza was built. There is evidence of a severe drought lasting about a hundred years that may have caused the decline of these civilizations, with new ones appearing in the aftermath. Babylonians came to dominate Mesopotamia while others, such as

14560-501: The Church would provide centralized authority and education. In the Middle East, Islam became the prominent religion and expanded into North Africa. It led to an Islamic Golden Age , inspiring achievements in architecture , the revival of old advances in science and technology, and the formation of a distinct way of life. The Christian and Islamic worlds would eventually clash, with

14742-470: The Homo genus. The name " Homo sapiens " means 'wise man' or 'knowledgeable man'. There is disagreement if certain extinct members of the genus, namely Neanderthals , should be included as a separate species of humans or as a subspecies of H. sapiens . Human is a loanword of Middle English from Old French humain , ultimately from Latin hūmānus , the adjectival form of homō ('man' – in

14924-566: The Kingdom of England , the Kingdom of France and the Holy Roman Empire declaring a series of holy wars to regain control of the Holy Land from Muslims . In the Americas, between 200 and 900 CE Mesoamerica was in its Classic Period , while further north, complex Mississippian societies would arise starting around 800 CE. The Mongol Empire would conquer much of Eurasia in the 13th and 14th centuries. Over this same time period,

15106-819: The Mali Empire in Africa grew to be the largest empire on the continent, stretching from Senegambia to Ivory Coast . Oceania would see the rise of the Tuʻi Tonga Empire which expanded across many islands in the South Pacific. By the late 15th century, the Aztecs and Inca had become the dominant power in Mesoamerica and the Andes , respectively. The early modern period in Europe and

15288-572: The Old World over the following millennia. It also occurred independently in Mesoamerica (about 6,000 years ago), China, Papua New Guinea , and the Sahel and West Savanna regions of Africa. Access to food surplus led to the formation of permanent human settlements , the domestication of animals and the use of metal tools for the first time in history. Agriculture and sedentary lifestyle led to

15470-629: The Poverty Point culture , Minoans and the Shang dynasty , rose to prominence in new areas. The Late Bronze Age collapse around 1200 BCE resulted in the disappearance of a number of civilizations and the beginning of the Greek Dark Ages . During this period iron started replacing bronze, leading to the Iron Age . In the 5th century BCE, history started being recorded as a discipline , which provided

15652-523: The Quran . Al-Kindi (801–873 CE) is usually regarded as the first philosopher of this tradition. He translated and interpreted many works of Aristotle and Neoplatonists in his attempt to show that there is a harmony between reason and faith . Avicenna (980–1037 CE) also followed this goal and developed a comprehensive philosophical system to provide a rational understanding of reality encompassing science, religion, and mysticism. Al-Ghazali (1058–1111 CE)

15834-565: The Renaissance Latin phrase studia humanitatis , which translates to study of humanity . This phrase was used to refer to the study of classical literature and language, which was seen as an important aspect of a refined education in the Renaissance . In its usage in the early 15th century, the studia humanitatis was a course of studies that consisted of grammar, poetry, rhetoric, history, and moral philosophy, primarily derived from

16016-766: The colonization of the Americas and the Columbian Exchange . This expansion led to the Atlantic slave trade and the genocide of Native American peoples . This period also marked the Scientific Revolution , with great advances in mathematics , mechanics , astronomy and physiology . The late modern period (1800–present) saw the Technological and Industrial Revolution bring such discoveries as imaging technology , major innovations in transport and energy development . Influenced by Enlightenment ideals,

16198-464: The novel ), poetry and drama , also lies at the heart of the modern humanities curriculum. College-level programs in a foreign language usually include study of important works of the literature in that language, as well as the language itself. In everyday language, law refers to a rule that is enforced by a governing institution, as opposed to a moral or ethical rule that is not subject to formal enforcement. The study of law can be seen as either

16380-425: The novel , short story or drama ; and works are often categorised according to historical periods, or according to their adherence to certain aesthetic features or expectations ( genre ). Philosophy—etymologically, the "love of wisdom"—is generally the study of problems concerning matters such as existence, knowledge, justification, truth, justice, right and wrong, beauty, validity, mind, and language. Philosophy

16562-420: The "things themselves", that is, as originally given in experience. They contend that this base-level of experience provides the foundation for higher-order theoretical knowledge, and that one needs to understand the former to understand the latter. An early approach found in ancient Greek and Roman philosophy is that philosophy is the spiritual practice of developing one's rational capacities. This practice

16744-434: The 19th-century Enlightenment were shattered not only by new discoveries of relativity by Einstein and of unseen psychology by Freud , but also by unprecedented technological development. Increasing global interaction during this time saw an equivalent influence of other cultures into Western art. Drawing is a means of making a picture , using a wide variety of tools and techniques. It generally involves making marks on

16926-412: The 5th century CE. Its focus was on religious topics and many thinkers used ancient philosophy to explain and further elaborate Christian doctrines . The Renaissance period started in the 14th century and saw a renewed interest in schools of ancient philosophy, in particular Platonism . Humanism also emerged in this period. The modern period started in the 17th century. One of its central concerns

17108-510: The Americas and Europe experienced a period of political revolutions known as the Age of Revolution . The Napoleonic Wars raged through Europe in the early 1800s, Spain lost most of its colonies in the New World , while Europeans continued expansion into Africa  – where European control went from 10% to almost 90% in less than 50 years  – and Oceania. In the 19th century,

17290-829: The Mediterranean. In West Asia, the Achaemenid Empire 's system of centralized governance became the precursor to many later empires, while the Gupta Empire in India and the Han dynasty in China have been described as golden ages in their respective regions. Following the fall of the Western Roman Empire in 476, Europe entered the Middle Ages . During this period, Christianity and

17472-739: The Near East ( c.  1450 –1800) began with the final defeat of the Byzantine Empire , and the rise of the Ottoman Empire . Meanwhile, Japan entered the Edo period , the Qing dynasty rose in China and the Mughal Empire ruled much of India. Europe underwent the Renaissance , starting in the 15th century, and the Age of Discovery began with the exploring and colonizing of new regions. This included

17654-437: The West, but elsewhere white may be. Some painters, theoreticians, writers and scientists, including Goethe , Kandinsky , Isaac Newton , have written their own colour theories . Moreover, the use of language is only a generalization for a colour equivalent. The word " red ", for example, can cover a wide range of variations on the pure red of the spectrum. Unlike music, where notes such as C or C# are universally accepted, there

17836-412: The analysis of language and to the question of whether, as Wittgenstein claimed, many of our philosophical confusions derive from the vocabulary we use; literary theory has explored the rhetorical, associative, and ordering features of language; and historical linguists have studied the development of languages across time. Literature, covering a variety of uses of language including prose forms (such as

18018-473: The available food, improving aesthetics , increasing knowledge or enhancing the exchange of resources. Humans are one of the most adaptable species, despite having a low or narrow tolerance for many of the earth's extreme environments. Currently the species is present in all eight biogeographical realms , although their presence in the Antarctic realm is very limited to research stations and annually there

18200-442: The basic limits of human understanding". Before the modern age, the term philosophy was used in a wide sense. It included most forms of rational inquiry, such as the individual sciences , as its subdisciplines. For instance, natural philosophy was a major branch of philosophy. This branch of philosophy encompassed a wide range of fields, including disciplines like physics, chemistry , and biology . An example of this usage

18382-436: The beginning of the 20th century. It discusses topics such as ethnophilosophy , négritude , pan-Africanism , Marxism, postcolonialism , the role of cultural identity, relativism , African epistemology , and the critique of Eurocentrism . Philosophical questions can be grouped into several branches. These groupings allow philosophers to focus on a set of similar topics and interact with other thinkers who are interested in

18564-561: The best long-distance runners in the animal kingdom, but slower over short distances. Humans' thinner body hair and more productive sweat glands help avoid heat exhaustion while running for long distances. Compared to other apes, the human heart produces greater stroke volume and cardiac output and the aorta is proportionately larger. Like most animals, humans are a diploid and eukaryotic species. Each somatic cell has two sets of 23 chromosomes , each set received from one parent; gametes have only one set of chromosomes, which

18746-423: The bulk of medieval education, with the emphasis being on the humanities as skills or "ways of doing". A major shift occurred with the Renaissance humanism of the fifteenth century, when the humanities began to be regarded as subjects to study rather than practice, with a corresponding shift away from traditional fields into areas such as literature and history ( studia humaniora ). In the 20th century, this view

18928-404: The church. However, in the Renaissance , a renewed focus on the physical world was reflected in art forms that depicted the human body and landscape in a more naturalistic and three-dimensional way. Eastern art has generally worked in a style akin to Western medieval art , namely a concentration on surface patterning and local colour (meaning the plain colour of an object, such as basic red for

19110-640: The collapse of most global empires, leading to widespread decolonization. Following the conclusion of the Second World War in 1945, the United States and the USSR emerged as the remaining global superpowers . This led to a Cold War that saw a struggle for global influence, including a nuclear arms race and a space race , ending in the collapse of the Soviet Union. The current Information Age , spurred by

19292-560: The color red, can exist at different locations at the same time. This is not the case for particulars including individual persons or specific objects. Other metaphysical questions are whether the past fully determines the present and what implications this would have for the existence of free will . There are many other subfields of philosophy besides its core branches. Some of the most prominent are aesthetics, philosophy of language, philosophy of mind, philosophy of religion, philosophy of science, and political philosophy. Aesthetics in

19474-771: The combined eastern and western Roman Empire in the 4th century AD. Bubonic plagues , first recorded in the 6th century AD, reduced the population by 50%, with the Black Death killing 75–200 million people in Eurasia and North Africa alone. Human population is believed to have reached one billion in 1800. It has since then increased exponentially, reaching two billion in 1930 and three billion in 1960, four in 1975, five in 1987 and six billion in 1999. It passed seven billion in 2011 and passed eight billion in November 2022. It took over two million years of human prehistory and history for

19656-414: The concept of deities, others do not. Therefore, the supernatural does not necessarily require the existence of deities. Rather, it can be broadly defined as any phenomena that cannot be explained by science or reason. Magical thinking creates explanations not available for empirical verification. Stories or myths are narratives being both didactic and entertaining. They are necessary for understanding

19838-461: The conclusion is true. One form is inductive reasoning . It starts from a set of individual cases and uses generalization to arrive at a universal law governing all cases. An example is the inference that "all ravens are black" based on observations of many individual black ravens. Another form is abductive reasoning . It starts from an observation and concludes that the best explanation of this observation must be true. This happens, for example, when

20020-614: The consequences of the general theories developed by normative ethics in specific situations, for example, in the workplace or for medical treatments. Within contemporary normative ethics, consequentialism, deontology , and virtue ethics are influential schools of thought. Consequentialists judge actions based on their consequences. One such view is utilitarianism , which argues that actions should increase overall happiness while minimizing suffering. Deontologists judge actions based on whether they follow moral duties, such as abstaining from lying or killing. According to them, what matters

20202-474: The continent, gradually replacing or interbreeding with local populations of archaic humans. Humans began exhibiting behavioral modernity about 160,000–70,000 years ago, and possibly earlier. This development was likely selected amidst natural climate change in Middle to Late Pleistocene Africa. The "out of Africa" migration took place in at least two waves, the first around 130,000 to 100,000 years ago,

20384-502: The cornerstones of the humanities; however, its popularity declined during the 20th century. Nevertheless, the influence of classical ideas on many humanities disciplines, such as philosophy and literature, remains strong. History is systematically collected information about the past . When used as the name of a field of study , history refers to the study and interpretation of the record of humans , societies , institutions, and any topic that has changed over time. Traditionally,

20566-423: The desire to understand and influence phenomena having motivated humanity's development of science , technology , philosophy , mythology , religion , and other frameworks of knowledge ; humans also study themselves through such domains as anthropology , social science , history , psychology , and medicine . There are estimated to be more than eight billion living humans . Although some scientists equate

20748-511: The development of the Internet and Artificial Intelligence systems, sees the world becoming increasingly globalized and interconnected. Early human settlements were dependent on proximity to water and – depending on the lifestyle – other natural resources used for subsistence , such as populations of animal prey for hunting and arable land for growing crops and grazing livestock. Modern humans, however, have

20930-623: The early 20th century, there has been continuous human presence in Antarctica through research stations and, since 2000, in space through habitation on the International Space Station . All modern humans are classified into the species Homo sapiens , coined by Carl Linnaeus in his 1735 work Systema Naturae . The generic name " Homo " is a learned 18th-century derivation from Latin homō , which refers to humans of either sex. The word human can refer to all members of

21112-482: The early stages of their career. On the other hand, graduates from more career-oriented programs often find jobs more quickly. However, the long-term career prospects of humanities graduates may be similar to those of other graduates, as research shows that by five years after graduation, they generally find a career path that appeals to them. There is empirical evidence that graduates from humanities programs earn less than graduates from other university programs. However,

21294-400: The emergence and application of formal logic , the focus on the role of language as well as pragmatism , and movements in continental philosophy like phenomenology, existentialism , and post-structuralism . The 20th century saw a rapid expansion of academic philosophy in terms of the number of philosophical publications and philosophers working at academic institutions . There was also

21476-668: The emergence of early civilizations . An urban revolution took place in the 4th millennium BCE with the development of city-states , particularly Sumerian cities located in Mesopotamia . It was in these cities that the earliest known form of writing, cuneiform script , appeared around 3000 BCE. Other major civilizations to develop around this time were Ancient Egypt and the Indus Valley Civilisation . They eventually traded with each other and invented technology such as wheels, plows and sails. Emerging by 3000 BCE,

21658-478: The emergence of non-Vedic teachings, like Buddhism and Jainism . Buddhism was founded by Gautama Siddhartha (563–483 BCE), who challenged the Vedic idea of a permanent self and proposed a path to liberate oneself from suffering . Jainism was founded by Mahavira (599–527 BCE), who emphasized non-violence as well as respect toward all forms of life. The subsequent classical period started roughly 200 BCE and

21840-404: The empirical evidence also shows that humanities graduates still earn notably higher incomes than workers with no postsecondary education, and have job satisfaction levels comparable to their peers from other fields. Humanities graduates also earn more as their careers progress; ten years after graduation, the income difference between humanities graduates and graduates from other university programs

22022-441: 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 . Major branches of philosophy are epistemology , ethics , logic , and metaphysics . Epistemology studies what knowledge is and how to acquire it. Ethics investigates moral principles and what constitutes right conduct. Logic

22204-456: The expressive and conceptual intention of the practitioner. Painting has been used throughout history to express spiritual and religious ideas, from mythological scenes on pottery to the frescoes of the Sistine Chapel , to body art. Colour is highly subjective, but has observable psychological effects, although these can differ from one culture to the next. Black is associated with mourning in

22386-407: The features that all entities have in common. Specific metaphysics is interested in different kinds of being, the features they have, and how they differ from one another. An important area in metaphysics is ontology . Some theorists identify it with general metaphysics. Ontology investigates concepts like being , becoming , and reality. It studies the categories of being and asks what exists on

22568-472: The first schools to require an extensive core curriculum in philosophy, literature, and the arts for all students. Other colleges with nationally recognized, mandatory programs in the liberal arts are Fordham University , St. John's College , Saint Anselm College and Providence College . Prominent proponents of liberal arts in the United States have included Mortimer J. Adler and E. D. Hirsch, Jr. In 1950, 1.2% of Americans aged 22 had earned

22750-561: The genomes of 1,184 individuals from 11 populations and identified 1.6 million single nucleotide polymorphisms . African populations harbor the highest number of private genetic variants. While many of the common variants found in populations outside of Africa are also found on the African continent, there are still large numbers that are private to these regions, especially Oceania and the Americas . By 2010 estimates, humans have approximately 22,000 genes. By comparing mitochondrial DNA , which

22932-580: The global average life expectancy at birth of a girl is estimated to be 74.9 years compared to 70.4 for a boy. There are significant geographical variations in human life expectancy, mostly correlated with economic development – for example, life expectancy at birth in Hong Kong is 87.6 years for girls and 81.8 for boys, while in the Central African Republic , it is 55.0 years for girls and 50.6 for boys. The developed world

23114-527: The history of philosophy include Western , Arabic–Persian , Indian , and Chinese philosophy . Other philosophical traditions are Japanese philosophy , Latin American philosophy , and African philosophy . Western philosophy originated in Ancient Greece in the 6th century BCE with the pre-Socratics . They attempted to provide rational explanations of the cosmos as a whole. The philosophy following them

23296-443: The human lifestyle. Genes and the environment influence human biological variation in visible characteristics, physiology , disease susceptibility, mental abilities, body size, and life span. Though humans vary in many traits, humans are among the least genetically diverse species. Any two humans are at least 99.5% genetically similar. Humans are sexually dimorphic : generally, males have greater body strength and females have

23478-550: The human population to reach one billion and only 207 years more to grow to 7 billion. The combined biomass of the carbon of all the humans on Earth in 2018 was estimated at 60 million tons, about 10 times larger than that of all non-domesticated mammals. In 2018, 4.2 billion humans (55%) lived in urban areas, up from 751 million in 1950. The most urbanized regions are Northern America (82%), Latin America (81%), Europe (74%) and Oceania (68%), with Africa and Asia having nearly 90% of

23660-505: The human population was reduced to a small number of breeding pairs. The forces of natural selection have continued to operate on human populations, with evidence that certain regions of the genome display directional selection in the past 15,000 years. The human genome was first sequenced in 2001 and by 2020 hundreds of thousands of genomes had been sequenced. In 2012 the International HapMap Project had compared

23842-566: The human predicament. Some other possible characteristics of religion are pollutions and purification, the sacred and the profane, sacred texts, religious institutions and organizations, and sacrifice and prayer. Some of the major problems that religions confront, and attempts to answer are chaos, suffering, evil, and death. The non-founder religions are Hinduism , Shinto , and native or folk religions . Founder religions are Judaism , Christianity , Islam , Confucianism , Daoism , Mormonism , Jainism , Zoroastrianism , Buddhism , Sikhism , and

24024-519: The humanities accounted for 15% of the bachelor's degrees awarded by colleges and universities in the United States. As of 2022, they accounted for less than 9%. Researchers in the humanities have developed numerous large- and small-scale digital corporations, such as digitized collections of historical texts, along with the digital tools and methods to analyze them. Their aim is both to uncover new knowledge about corpora and to visualize research data in new and revealing ways. Much of this activity occurs in

24206-545: The humanities and closer to the formal sciences , becoming much more analytic. Analytic philosophy is marked by emphasis on the use of logic and formal methods of reasoning, conceptual analysis, and the use of symbolic and/or mathematical logic , as contrasted with the Continental style of philosophy . This method of inquiry is largely indebted to the work of philosophers such as Gottlob Frege , Bertrand Russell , G.E. Moore and Ludwig Wittgenstein . Religious Studies

24388-493: The humanities reject. Renaissance scholars and artists are also known as humanists . Some secondary schools offer humanities classes usually consisting of literature , history , foreign language , and art . Human disciplines like history and language mainly use the comparative method and comparative research . Other methods used in the humanities include hermeneutics , source criticism , esthetic interpretation , and speculative reason . The word humanities comes from

24570-451: The humanities, these are often considered social sciences . Similarly, disciplines such as finance , business administration , political science , economics , and global studies have closer ties to the social sciences rather than the humanities. Scholars in the humanities are called humanities scholars or sometimes humanists . The term humanist also describes the philosophical position of humanism , which antihumanist scholars in

24752-420: The importance of a strong state and strict laws. Buddhism was introduced to China in the 1st century CE and diversified into new forms of Buddhism . Starting in the 3rd century CE, the school of Xuanxue emerged. It interpreted earlier Daoist works with a specific emphasis on metaphysical explanations. Neo-Confucianism developed in the 11th century CE. It systematized previous Confucian teachings and sought

24934-419: The indigenous Shinto religion and Chinese and Indian thought in the forms of Confucianism and Buddhism, both of which entered Japan in the 6th and 7th centuries. Its practice is characterized by active interaction with reality rather than disengaged examination. Neo-Confucianism became an influential school of thought in the 16th century and the following Edo period and prompted a greater focus on language and

25116-483: The interconnectedness of all things. Latin American philosophy during the colonial period , starting around 1550, was dominated by religious philosophy in the form of scholasticism . Influential topics in the post-colonial period were positivism , the philosophy of liberation , and the exploration of identity and culture. Early African philosophy, like Ubuntu philosophy , was focused on community, morality, and ancestral ideas. Systematic African philosophy emerged at

25298-567: The late Miocene epoch. During this split, chromosome 2 was formed from the joining of two other chromosomes, leaving humans with only 23 pairs of chromosomes, compared to 24 for the other apes. Following their split with chimpanzees and bonobos, the hominins diversified into many species and at least two distinct genera. All but one of these lineages – representing the genus Homo and its sole extant species Homo sapiens  – are now extinct. The genus Homo evolved from Australopithecus . Though fossils from

25480-551: The manifestation of cognitive virtues instead of justification; or they deny that knowledge can be analyzed in terms of other phenomena. Another area in epistemology asks how people acquire knowledge. Often-discussed sources of knowledge are perception , introspection , memory , inference , and testimony . According to empiricists , all knowledge is based on some form of experience. Rationalists reject this view and hold that some forms of knowledge, like innate knowledge , are not acquired through experience. The regress problem

25662-496: 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

25844-596: The most fundamental level. Another subfield of metaphysics is philosophical cosmology . It is interested in the essence of the world as a whole. It asks questions including whether the universe has a beginning and an end and whether it was created by something else. A key topic in metaphysics concerns the question of whether reality only consists of physical things like matter and energy. Alternative suggestions are that mental entities (such as souls and experiences ) and abstract entities (such as numbers) exist apart from physical things. Another topic in metaphysics concerns

26026-404: The most influential philosophers of the subsequent period. The increasing influence of Western thought and institutions in the 19th and 20th centuries gave rise to the intellectual movement of Islamic modernism , which aims to understand the relation between traditional Islamic beliefs and modernity. One of the distinguishing features of Indian philosophy is that it integrates the exploration of

26208-472: The natural and social sciences, religion, and mathematics. Epistemology is the branch of philosophy that studies knowledge. It is also known as theory of knowledge and aims to understand what knowledge is, how it arises, what its limits are, and what value it has. It further examines the nature of truth , belief , justification , and rationality . Some of the questions addressed by epistemologists include "By what method(s) can one acquire knowledge?"; "How

26390-504: The natural world. The Kyoto School emerged in the 20th century and integrated Eastern spirituality with Western philosophy in its exploration of concepts like absolute nothingness ( zettai-mu ), place ( basho ), and the self . Latin American philosophy in the pre-colonial period was practiced by indigenous civilizations and explored questions concerning the nature of reality and the role of humans. It has similarities to indigenous North American philosophy , which covered themes such as

26572-455: The nature and sources of morality. It analyzes the meaning of ethical concepts, like right action and obligation . It also investigates whether ethical theories can be true in an absolute sense and how to acquire knowledge of them. Normative ethics encompasses general theories of how to distinguish between right and wrong conduct. It helps guide moral decisions by examining what moral obligations and rights people have. Applied ethics studies

26754-467: The nature of reality, the ways of arriving at knowledge, and the spiritual question of how to reach enlightenment . It started around 900 BCE when the Vedas were written. They are the foundational scriptures of Hinduism and contemplate issues concerning the relation between the self and ultimate reality as well as the question of how souls are reborn based on their past actions . This period also saw

26936-555: The ongoing mass extinction of other forms of life. Within the last century, humans have explored challenging environments such as Antarctica , the deep sea , and outer space . Human habitation within these hostile environments is restrictive and expensive, typically limited in duration, and restricted to scientific , military , or industrial expeditions. Humans have visited the Moon and made their presence known on other celestial bodies through human-made robotic spacecraft . Since

27118-442: The only primates to have short, relatively flush canine teeth . Humans have characteristically crowded teeth, with gaps from lost teeth usually closing up quickly in young individuals. Humans are gradually losing their third molars , with some individuals having them congenitally absent. Humans share with chimpanzees a vestigial tail, appendix , flexible shoulder joints, grasping fingers and opposable thumbs . Humans also have

27300-433: The other performing arts. In addition to the standard narrative dialogue style, theatre takes such forms as opera , ballet , mime , kabuki , classical Indian dance , Chinese opera , mummers' plays , and pantomime . Dance (from Old French dancier , perhaps from Frankish ) generally refers to human movement either used as a form of expression or presented in a social , spiritual or performance setting. Dance

27482-474: The palm of the hand and on the soles of the feet. It is estimated that the worldwide average height for an adult human male is about 171 cm (5 ft 7 in), while the worldwide average height for adult human females is about 159 cm (5 ft 3 in). Shrinkage of stature may begin in middle age in some individuals but tends to be typical in the extremely aged . Throughout history, human populations have universally become taller, probably as

27664-436: The philosophical sense is the field that studies the nature and appreciation of beauty and other aesthetic properties, like the sublime . Although it is often treated together with the philosophy of art , aesthetics is a broader category that encompasses other aspects of experience, such as natural beauty. In a more general sense, aesthetics is "critical reflection on art, culture, and nature ". A key question in aesthetics

27846-511: The population density varies from one region to another, and large stretches of surface are almost completely uninhabited, like Antarctica and vast swathes of the ocean. Most humans (61%) live in Asia; the remainder live in the Americas (14%), Africa (14%), Europe (11%), and Oceania (0.5%). Estimates of the population at the time agriculture emerged in around 10,000 BC have ranged between 1 million and 15 million. Around 50–60 million people lived in

28028-417: The precise definition of the term and its meaning has changed throughout the ages. Metaphysicians attempt to answer basic questions including " Why is there something rather than nothing?

There are many other subfields besides them and the different divisions are neither exhaustive nor mutually exclusive.

Furthermore, philosophical inquiry sometimes overlaps with other disciplines in

28938-410: The same way as the sciences. This problem is avoided by seeing philosophy as an immature or provisional science whose subdisciplines cease to be philosophy once they have fully developed. In this sense, philosophy is sometimes described as "the midwife of the sciences". Other definitions focus on the contrast between science and philosophy. A common theme among many such conceptions is that philosophy

30212-598: The study of the biggest patterns of the world as a whole or as the attempt to answer the big questions. Such an approach is pursued by Immanuel Kant , who holds that the task of philosophy is united by four questions: "What can I know?"; "What should I do?"; "What may I hope?"; and "What is the human being?" Both approaches have the problem that they are usually either too wide, by including non-philosophical disciplines, or too narrow, by excluding some philosophical sub-disciplines. Many definitions of philosophy emphasize its intimate relation to science. In this sense, philosophy

31304-569: The works of Jean Dubuffet or Anselm Kiefer . Modern and contemporary art has moved away from the historic value of craft in favour of concept ( conceptual art ); this has led some e.g. Joseph Kosuth to say that painting, as a serious art form, is dead, although this has not deterred the majority of artists from continuing to practise it either as whole or part of their work. Sculpture involves creating three-dimensional forms out of various materials. These typically include malleable substances like clay and metal but may also extend to material that
