Ionian School (philosophy) - Anaximander

Anaximander

Anaximander (Greek: Ἀναξίμανδρος) (610 BCE – ca. 546 BCE) wrote a cosmological work, little of which remains. From the few extant fragments, we learn that he believed the beginning or first principle (arche, a word first found in Anaximander's writings, and which he probably invented) is an endless, unlimited mass (apeiron), subject to neither old age nor decay, which perpetually yields fresh materials from which everything we can perceive is derived.
