Etiology
Etiology (pronounced ; alternatively: aetiology or ætiology) is the study of causation or origination. The word is derived from the Greek (''aitiología'') "giving a reason for" (, ''aitía'', "cause"); and ('' -logía''). More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine (pertaining to causes of disease) and in philosophy, but also in physics, psychology, government, geography, spatial analysis, theology, and biology, in reference to the causes or origins of various phenomena. In the past, when many physical phenomena were not well understood or when histories were not recorded, myths often arose to provide etiologies. Thus, an etiological myth, or origin myth, is a myth that has arisen, been told over time or written to explain the origins of various social or natural phenomena. For example, Virgil's ''Aeneid'' i ...

Origin Myth
An origin myth is a myth that describes the origin of some feature of the natural or social world. One type of origin myth is the creation or cosmogonic myth, a story that describes the creation of the world. However, many cultures have stories set in a time after a first origin - such stories aim to account for the beginnings of natural phenomena or of human institutions within a preexisting universe. In Graeco-Roman scholarship, the terms etiological myth and ''aition'' (from the Ancient Greek αἴτιον, "cause") are sometimes used for a myth that explains an origin, particularly how an object or custom came into existence. Nature of origin myths Every origin myth is a tale of creation: origin myths describe how some reality came into existence.Eliade, p. 21 In many cases, origin myths also justify the established order by explaining that it was established by sacred forces (see section on "Social function" below). The distinction between cosmogonic myths and or ...

Causality
Causality (also referred to as causation, or cause and effect) is influence by which one event, process, state, or object (''a'' ''cause'') contributes to the production of another event, process, state, or object (an ''effect'') where the cause is partly responsible for the effect, and the effect is partly dependent on the cause. In general, a process has many causes, which are also said to be ''causal factors'' for it, and all lie in its past. An effect can in turn be a cause of, or causal factor for, many other effects, which all lie in its future. Some writers have held that causality is metaphysically prior to notions of time and space. Causality is an abstraction that indicates how the world progresses. As such a basic concept, it is more apt as an explanation of other concepts of progression than as something to be explained by others more basic. The concept is like those of agency and efficacy. For this reason, a leap of intuition may be needed to grasp it. According ...

Medicine
Medicine is the science and practice of caring for a patient, managing the diagnosis, prognosis, prevention, treatment, palliation of their injury or disease, and promoting their health. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. Medicine has been practiced since prehistoric times, and for most of this time it was an art (an area of skill and knowledge), frequently having connections to the religious and philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers fo ...

Scurvy
Scurvy is a deficiency disease, disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, anemia, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and Kidney dialysis, dialysis. While many animals produce their own vitamin C, humans and a few others do not. Vitamin C is required to make the building blocks for collagen. Diagnosis is typically based on physical signs, X-rays, and improvement after treatment. Treatment is with vitamin ...

Dolphin
A dolphin is an aquatic mammal within the infraorder Cetacea. Dolphin species belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species named as dolphins. Dolphins range in size from the and Maui's dolphin to the and orca. Various species of dolphins exhibit sexual dimorphism where the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can briefly travel at speeds of per hour or leap about . Dolphins use their conical teeth to capture fast-moving prey. They have well-developed hearing which is adapted for both air and water. It is so well developed that some can survive even if they are blind. Some species are well adapted for diving to great depths. The ...

Homeric Hymn
The ''Homeric Hymns'' () are a collection of thirty-three anonymous ancient Greek hymns celebrating individual gods. The hymns are "Homeric" in the sense that they employ the same epic meter—dactylic hexameter—as the ''Iliad'' and ''Odyssey'', use many similar formulas and are couched in the same dialect. While the modern scholarly consensus is that they were not written during the lifetime of Homer himself, they were uncritically attributed to him in antiquity—from the earliest written reference to them, Thucydides (iii.104)—and the label has stuck. "The whole collection, as a collection, is ''Homeric'' in the only useful sense that can be put upon the word," A. W. Verrall noted in 1894, "that is to say, it has come down labeled as 'Homer' from the earliest times of Greek book-literature." History The oldest of the hymns were probably written in the seventh century BC, somewhat later than Hesiod and the usually accepted date for the writing down of the Homeric ep ...

Delphi
Delphi (; ), in legend previously called Pytho (Πυθώ), in ancient times was a sacred precinct that served as the seat of Pythia, the major oracle who was consulted about important decisions throughout the ancient classical world. The oracle had origins in prehistory and it became international in character and also fostered sentiments of Greek nationality, even though the nation of Greece was centuries away from realization. The ancient Greeks considered the centre of the world to be in Delphi, marked by the stone monument known as the omphalos (navel). The sacred precinct of Ge or Gaia was in the region of Phocis, but its management had been taken away from the Phocians, who were trying to extort money from its visitors, and had been placed in the hands of an amphictyony, or committee of persons chosen mainly from Central Greece. According to the Suda, Delphi took its name from the Delphyne, the she-serpent ('' drakaina'') who lived there and was killed by the god Apoll ...

Mythology
Myth is a folklore genre consisting of narratives that play a fundamental role in a society, such as foundational tales or origin myths. Since "myth" is widely used to imply that a story is not objectively true, the identification of a narrative as a myth can be highly controversial. Many adherents of religions view their own religions' stories as truth and so object to their characterization as myth, the way they see the stories of other religions. As such, some scholars label all religious narratives "myths" for practical reasons, such as to avoid depreciating any one tradition because cultures interpret each other differently relative to one another. Other scholars avoid using the term "myth" altogether and instead use different terms like "sacred history", "holy story", or simply "history" to avoid placing pejorative overtones on any sacred narrative. Myths are often endorsed by secular and religious authorities and are closely linked to religion or spirituality. Many ...

Vitamin C
Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits and vegetables, also sold as a dietary supplement and as a topical 'serum' ingredient to treat melasma (dark pigment spots) and wrinkles on the face. It is used to prevent and treat scurvy. Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. Most animals are able to synthesize their own vitamin C. However, apes (including humans) and monkeys (but not all primates), most bats, some rodents, and certain other animals must acquire it from dietary sources. There is some evidence that regular use of supplements may reduce the duration of the common cold, but it does not appear to prevent infection. It is unclear whether ...

Inferred
Inferences are steps in reasoning, moving from premises to logical consequences; etymologically, the word ''infer'' means to "carry forward". Inference is theoretically traditionally divided into deduction and induction, a distinction that in Europe dates at least to Aristotle (300s BCE). Deduction is inference deriving logical conclusions from premises known or assumed to be true, with the laws of valid inference being studied in logic. Induction is inference from particular evidence to a universal conclusion. A third type of inference is sometimes distinguished, notably by Charles Sanders Peirce, contradistinguishing abduction from induction. Various fields study how inference is done in practice. Human inference (i.e. how humans draw conclusions) is traditionally studied within the fields of logic, argumentation studies, and cognitive psychology; artificial intelligence researchers develop automated inference systems to emulate human inference. Statistical infere ...
