Apeiron
Apeiron
(Gr. apeiron) The boundless; the indeterminate; the infinite. In the philosophy of Anaximander the apeiron is the primal indeterminate matter out of which all things come to be. The apeiron appears frequently elsewhere in early Greek philosophy, notably in the dualism of the Pythagoreans, where it is opposed to the principle of the Limit (peras), or number. — G.R.M.
