First appearance: Anaximenes
As a supporting figure in The Lives and Opinions of Eminent Philosophers, Anaximenes is not background color—the story leans on what they do once the chapter opens.
Main subject of the chapter; pupil of Anaximander, philosopher who taught air as the first principle.
Anaximenes of Miletus was the third of the great Milesian cosmologists, following Thales and Anaximander, and he taught that everything arises from air through rarefaction and condensation. His surviving letters to Pythagoras paint a different picture: a man anxious about the Medes, urging his friend to stay safe in Crotona while the Ionians face slavery. He matters because he shows the Pre-Socratic project not as abstract speculation but as a way of life under political threat.
