Black-and-white dualism

Religion and mythology

• The Genesis creation narrative has God "separate light from darkness" on the First Day.

• The Bible associates light with God, truth, and virtue; darkness is associated with sin and the Devil. Painters such as Rembrandt portrayed divine light illuminating an otherwise dark world.^[1]
• War of the Sons of Light Against the Sons of Darkness, part of the Dead Sea Scrolls.
• The underworld (Hades, Tartarus) was imagined as a chthonic place of darkness, contrasting with the celestial realm of the gods. Christian notions of heaven and hell inherit this conception, as do the "dark angels" vs. the unfallen angels, often with aureola (halos), in Christian mythology.
• Day and night are personified as deities in various mythologies (i.e. Norse Dagr and Nótt, Greek Hemera and Nyx, et cetera).

Dress

• White often represents purity or innocence in Western culture,^[2] particularly as white clothing or objects can be stained easily. In most Western countries white is the color worn by brides at weddings. Angels are typically depicted as clothed in white robes.
  • In many Hollywood Westerns, bad cowboys wear black hats while the good ones wear white.
  • Melodrama villains are dressed in black and heroines in white dresses.
  • This can be reversed as a deliberate play on conventions, by having the evil character dress in white, as a symbol of their hypocrisy or arrogance. For example, Don Fanucci in The Godfather, Part II is an evil character, but wears an expensive all-white suit as a sign of his esteem, power and prestige. Sometimes protagonists can wear black too, as in Return of the Jedi, wherein Luke Skywalker wears black during the final battle.
  • In computer security, a black hat is an attacker with evil intentions, while a white hat bears no such ill will. (This is derived from the Western movie convention.)

Magic

• Healing or "good" paranormal magic is called White magic. Black magic is a destructive or evil form of magic.
  • A Treatise on White Magic is a book by Alice Bailey, a Theosophist.^[3]
  • White witch.
  • Evil witches are stereotypically dressed in black and good fairies in white.

Popular Culture

• The topos of "light and darkness" is also reflected in numerous titles in popular culture, such as Heart of Darkness (1899), Light in My Darkness (1927), Darkness and the Light (1942), Creatures of Light and Darkness (1969), From Darkness to Light (1973), Darkness and Light (1989), The Lord of the Light and of the Darkness (1993), the Star Trek: Deep Space 9 episode "The Darkness and the Light" (1997), the Babylon 5 episode "Between the Darkness and the Light" (1997), and Out of the Darkness, Into the Light (1998).
• In works of fantasy fiction, the main antagonist is often called a "Dark Lord", for example Sauron in The Lord of the Rings.
• George Orwell makes a bitterly ironic use of the "light and darkness" topos in his Nineteen Eighty Four. In the early part of the book the protagonist gets a promise that "We will meet in the place where there is no darkness" – which he interprets as referring to a place where the oppressive totalitarian state does not rule. But the man who made the promise was in fact an agent of the Thought Police – and they eventually meet as prisoner and interrogator where there is indeed no darkness, in detention cells where the light remains on permanently, day and night, as an additional means of torturing detainees.

Other Examples

• The Dark Ages vs. the Age of Enlightenment.
• "Black and white thinking" is the false dichotomy of assuming anything not good is evil and vice versa.
