A delusion is commonly defined as a fixed false belief and is used in everyday language to describe a belief that is either false, fanciful or derived from deception. In psychiatry, the definition is necessarily more precise and implies that the belief is pathological (the result of an illness or illness process). Delusions typically occur in the context of neurological or mental illness, although they are not tied to any particular disease and have been found to occur in the context of many pathological states (both physical a ...

Although non-specific concepts of madness have been around for several thousand years, the psychiatrist and philosopher Karl Jaspers was the first to define the three main criteria for a belief to be considered delusional in his book General Psychopathology. These criteria are: certainty (held with absolute conviction) incorrigibility (not changeable by compelling counterargument or proof to the contrary) impossibility or falsity of conte ...

The Cotard delusion or Cotard's syndrome is a rare disorder in which a person holds a delusional belief that he is dead, does not exist, is putrefying or has lost his blood or internal organs. It is named after Jules Cotard (1840 - 1889) a French neurologist who first described the condition, which he called le délire de négation ("negation delirium"), in a lecture in Paris in 1880. In this lecture, Cotard described a patient with the moniker of Mademoiselle X, who denied the existence of God, the Devil, several parts of her body and denied she needed to eat. Later she believed she was ete ...

In the sociology of religion, secondary conversion is conversion to a religion not due to any inherent attractiveness of the religion, but rather due to a pre-existing relationship with another convert to the religion. For example, someone might join a religious group primarily because their spouse or partner is doing so; such a person would be a secondary convert. Secondary converts are people who join a religion only because of a relationship with the other convert. Other related archivesso

Delusion (Ignorance)

"Delusion refers to belief in something that contradicts reality. In Buddhism, delusion is ... a lack of awareness of the true nature or Buddha nature of things, or of the true meaning of existence. "

According to the Buddhist outlook, we are deluded by our senses-- among which intellect (discriminating, discursive thought) is included as a sixth sense.

Consciousness, attached to the senses, leads us into error by causing us to take the world of appearances for the world of reality, whereas in fact it is only a limited and fleeting aspect of reality." (The Shambhala Dictionary of Buddhism and Zen.)

There is strong neuropsychological evidence that the Capgras delusion is, at least in part, related to a loss of emotional response to familiar faces. This is in the context of generally good (although not always perfectly intact) face perception abilities. This seems to be the reverse of prosopagnosia, a condition where conscious face recognition abilities are lost, despite sufferers still showing a covert emotional response to familiar faces, detectable b ...

It is named after Joseph Capgras (1873-1950), a French psychiatrist who first described the disorder in a paper by Capgras and Reboul-Lachaux[2][3] in 1923. They used the term l'illusion des sosies (the illusion of doubles) to describe the case of a French woman who complained that various "doubles" had taken the place of people she knew. However, the term illusion has a subtly different meaning from delusion in psychiatry so "Capgr ...

Current cognitive neuropsychology research points toward a two-factor approach to the cause of monothematic delusions1. The first factor being the anomalous experience—often a neurological defect—which leads to the delusion and the second factor being an impairment of the belief formation cognitive process. For example of one of these first factors, several studies point toward Capgras delusion being the result of a disorder of the affect component of face perception. As a result, while the person can recognize their sp ...

Oneness of delusion and enlightenment

(Jpn.: meigo-funi or meigo-ittai)

Also, non-duality of delusion and enlightenment. The principle that delusion and enlightenment are, though different in aspect, one and the same in their essential nature. A bad cause or influence gives rise to delusion, and a good cause or influence, to enlightenment. Delusion and enlightenment are two different workings, but both arise from the essential nature of life. This Mahayana concept contrasts with the Hinayana view that enlightenment and delusion, or enlightenment and earthly desires, are mutually exclusive and incompatible.

Litigants who challenge a will sometimes allege that the testator laboured under an "insane delusion" or monomania that rendered them incapable of judging rationally the deserts of their presumed heirs; one court has defined "insane delusions" as "those that are so contrary to human nature that it would lead to the inference that some mental defect existed." This test is also lenient. In the 1854 case of Addington v. Wilson, the Supreme Court of Indiana held that a testator who disinherited his daughters because he believed the ...

The Xhosa tribes gave the colony few problems after the war. This was due, in large measure, to an extraordinary delusion which arose among the Xhosa in 1856, and led in 1857 to the death of some 50,000 people. This incident is one of the most remarkable instances of misplaced faith recorded in history. The Xhosa had not accepted their defeat in 1853 as decisive and were preparing to renew their struggle with the Europeans. In 1854, a disease spread through the cattle of the Xhosa. It was believed to have spread from cattle owned by t ...

The first radio series was broadcast on BBC Radio 4 in 1978. It was split into episodes, known as "Fits" (an archaic term for a section of a poem revived by Lewis Carroll for The Hunting of the Snark). The original series comprised Fits the First through Sixth. Fits the Fifth and Sixth were co-written by John Lloyd; subsequent versions of the story omit most of Lloyd's material. The success of the series encouraged Adams to adapt it into a novel, which was based on the first four Fits and released in 1979. A slightly contracted ...
