When one takes the four elements and includes with them Aether or Spirit, one reaches five. Five also numbers the faces of the pyramid, when one includes the base; it is also the number of the regular polyhedra, or Pythagorean solids.

Five is an important number to the Discordian Movement, with its Funfwissenschaft or Law of Fives.

Meanwhile, in China, five is the number of the Taoist elements: fire, earth, metal, water, and wood.
