What's the difference between dichotomy and duality?

Dichotomy


Definition:

  • (n.) A cutting in two; a division.
  • (n.) Division or distribution of genera into two species; division into two subordinate parts.
  • (n.) That phase of the moon in which it appears bisected, or shows only half its disk, as at the quadratures.
  • (n.) Successive division and subdivision, as of a stem of a plant or a vein of the body, into two parts as it proceeds from its origin; successive bifurcation.
  • (n.) The place where a stem or vein is forked.
  • (n.) Division into two; especially, the division of a class into two subclasses opposed to each other by contradiction, as the division of the term man into white and not white.

Duality


Definition:

  • (n.) The quality or condition of being two or twofold; dual character or usage.
