Anaximander

Ancient Greek philosopher from Miletus, student of Thales, who posited the apeiron — the indefinite or boundless — as the primordial principle from which all things come and to which they return.

The apeiron is the arche (primary principle): not any definite element (water, fire) but an indefinite source from which opposites emerge through eternal motion. Things pay penalty and retribution to one another for their injustice according to the order of time.
