Definition

Proper noun A pre-Socratic Greek philosopher from Miletus (6th century BC). He was a pupil or associate of Anaximander and proposed that air (aer) is the fundamental substance (arche) from which all things originate through the processes of rarefaction and condensation.

Usage

The word "Anaximenes" is used exclusively as a proper noun to refer to the historical figure, his philosophical school of thought, or his specific doctrines. * In historical and philosophical texts, he is cited as one of the three major Milesian philosophers, alongside Thales and Anaximander. * His theory is often summarized as the belief that "all is air."
