In religion, folklore, and mythology a demon (or daemon, dæmon, daimon from Greek: δαίμων 1) is a supernatural being that is generally described as a malevolent spirit. In Christian terms demons are generally understood as fallen angels, formerly of God. A demon is frequently depicted as a force that may be conjured and insecurely controlled. The "good" demon in recent use is largely a literary device (e.g., Maxwell's demon), though references to good demons can be found in Hesiod and Shakespeare. In common language, to "demonize" a person means to characterize or portray them as evil, or as the source of evil.

History

The Greek conception of a daemon (< δαίμων daimōn) appears in the works of Plato and many other ancient authors, but without the evil connotations which are apparent in the Septuagint translation of the Hebrew Bible and in the Greek originals of the New Testament. The medieval and neo-medieval conception of a "demon" in Western civilization (see the Medieval grimoire called the Ars Goetia) derives seamlessly Fact: date=December 2007 from the ambient popular culture of Late (Roman) Antiquity. Greco-Roman concepts of daemons that passed into Christian culture are discussed in the entry daemon, though it should be duly noted that the term referred only to a spiritual force, not a malevolent supernatural being.Fact: date=December 2007 The Hellenistic "daemon" eventually came to include many Semitic and Near Eastern gods as evaluated by Christianity.Fact: date=December 2007

The supposed existence of demons is an important concept in many modern religions and occultist traditions. In some present-day cultures, demons are still feared in popular superstition, largely due to their alleged power to possess living creatures.

In the contemporary Western occultist tradition (perhaps epitomized by the work of Aleister Crowley), a demon, such as Choronzon, the "Demon of the Abyss", is a useful metaphor for certain inner psychological processes, though some may also regard it as an objectively real phenomenon.

Some scholars believe that large portions of the demonology (see Asmodai) of Judaism, a key influence on Christianity and Islam, originated in Zoroastrianism, and were transferred to Judaism during the Persian era.

Etymology

The idea of demons is as old as religion itself, and the word demon seems to have ancient origins. The Merriam-Webster dictionary gives the etymology of the word as Greek daimon, probably from the verb daiesthai meaning "to divide, distribute." The Proto-Indo-European root *deiwos for god, originally an adjective meaning "celestial" or "bright, shining" has retained this meaning in many related Indo-European languages and cultures (Sanskrit deva, Latin deus, German Tiw, Welsh 2,]), but also provided another other common word for demon in Avestan daeva.
