The evil demon, sometimes referred to as the evil genius, is a concept in Cartesian philosophy. In his 1641 Meditations on First Philosophy, René Descartes hypothesized the existence of an evil demon, a personification who is "as clever and deceitful as he is powerful, who has directed his entire effort to misleading me." The evil demon presents a complete illusion of an external world, including other minds, to Descartes' senses, where in fact there is no such external world in existence. The evil genius also presents to Descartes' senses a complete illusion of his own body, including all bodily sensations, when in fact Descartes has no body. Most Cartesian scholars opine that the evil demon is also omnipotent, and thus capable of altering mathematics and the fundamentals of logic.
The evil demon has a parallel with Berkeley's concept of a consensus reality supported by God. It is one of several methods of systematic doubt that Descartes employs in the Meditations.

Famous quotes containing the words evil and/or demon:
“An evil moon bleeds drops of death.
The earth burns brown.
Grass shrivels and dries to a yellowish mass.
Earth wears a dun-colored dress
like an old woman wooing the sun to be her lover,
be her sweetheart and her husband bound in one.”
—Margaret Abigail Walker (b. 1915)
“Not necessity, not desire—no, the love of power is the demon of mankind. Grant them everything, health, food, housing, entertainment—they are and remain unhappy and anxious: for the demon waits and waits, and wants to be satisfied.”
—Friedrich Nietzsche (1844–1900)
