The Empedoclean cosmic cycle is the doctrine, set out in the fifth century BC Sicilian philosopher Empedocles' poem On Nature, that the four eternal roots, fire, air, earth and water, are alternately united and separated by two opposed cosmic forces, Love and Strife, in a repeating cycle with no beginning or end. Nothing is created or destroyed; what is called birth and death is only these roots mixing and separating in new proportions. At the extreme of Love's ascendancy the roots blend completely into a motionless, undifferentiated sphere, and as Strife enters and separates them, the world presently known, with its plants, animals and people, forms during one stage of that separation.

Proposed DatingThe stage of Strife's separation in which limbs and organs are said to wander alone and join at random, so that only the combinations able to survive persist, has drawn comparison to natural selection. 1 Some modern commentators read the passage, in which viable random combinations of limbs and organs alone survive to form the animals and people of the present world, as an early anticipation of natural selection; others judge the resemblance superficial, since Empedocles describes a single cosmogonic episode within the eternal cycle rather than an ongoing process of selection repeated across generations. Identity
SymbolThe Sphairos, a motionless sphere in which the four roots stand wholly blended and no individual thing exists, is the doctrine's own image for the extreme of Love's ascendancy, and appears in Empedocles' own verses as very nearly a divine being in its own right. 1 Attributions
