Anaximenes' αηρ as Generating Mist and Generated Air

Abstract

Anaximenes is usually considered to be a material monist recognizing transparent atmospheric air as a principle (ρχ). In the cosmogonic explanation of the origin of the earth and the heavenly bodies, the Greek term ρ turns out to mean rather 'opaque damp mist'. However, Not only does it accord with archaic usage, but also with how it was used in his mentor, Anaximander. Yet, in cosmology ρ means 'air' serving as stuff on which the earth and the heavenly bodies float. Hence, in keeping with contemporary usage, Anaximenes recognised two kinds of ρ, distinguishing them functionally. Whereas mist is conceived of as a generating substance, air functions only as carrying stuff.
