Anaximander

Metaphysics

Anaximander was a Greek philosopher of the sixth century BC, born around 610 BC and dying around 546 BC in Miletus, in Ionia on the coast of present day Turkey, where he was a member of the Milesian school alongside Thales and Anaximenes. He is remembered as one of the first thinkers to propose a naturalistic account of the origin of the cosmos, arguing that the source of all things is not any single familiar element such as water but the apeiron, an unbounded or indefinite substance from which the opposites, hot and cold, wet and dry, separate out to form the world. Anaximander also described a mechanical, unsupported Earth floating freely at the center of the universe and offered early speculative accounts of the origins of animals and human beings, work that has led some historians to credit him as an early founder of cosmology and of scientific inquiry into nature more broadly.
