Delusion

Delusion

A delusion is a belief held with strong conviction despite superior evidence to the contrary. Unlike hallucinations, delusions are always pathological (the result of an illness or illness process). As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, or other effects of perception.

Famous quotes containing the word delusion:

    No delusion is greater than the notion that method and industry can make up for lack of mother-wit, either in science or in practical life.
    Thomas Henry Huxley (1825–1895)

    Again and again, faith in a possible satisfaction of the human race breaks through at the very moments of most zealous discord because humankind will never be able to live and work without this consoling delusion of its ascent into morality, without this dream of final and ultimate accord.
    Stefan Zweig (18811942)

    There exists a black kingdom which the eyes of man avoid because its landscape fails signally to flatter them. This darkness, which he imagines he can dispense with in describing the light, is error with its unknown characteristics.... Error is certainty’s constant companion. Error is the corollary of evidence. And anything said about truth may equally well be said about error: the delusion will be no greater.
    Louis Aragon (1897–1982)
