"Herakleitos... explained the world by man rather than man by the world. ...Aristotle implies that soul is identical with the dry exhalation, and this is ...confirmed by the fragments. Man is made... of... fire, water, and earth. But, just as in the macrocosm fire is... the one wisdom, so in the microcosm... fire alone is conscious. When it has left the body..., the mere earth and water, is... worthless (fr. 85)."
