The astronomer and mathematician Thales of Miletus is believed to have been the first ancient Greek scholar to discuss the phenomenon of magnetism. Aristotle notes in On the Soul that Thales held the belief that “the magnet has a soul in it because it moves the iron.” Five and a half centuries later, Diogenes Laërtius concurred with Aristotle, observing that Thales “attributed a soul or life even to inanimate objects.”

After he was captured by pirates, Diogenes of Sinope was sold as a slave to Xeniades, who had the Cynic philosopher educate his sons. “At home he taught them to attend to their own needs,” writes Diogenes Laërtius in his Lives of the Eminent Philosophers, “to live on plain food and water, to wear their hair short and unadorned, to go barefoot and without a tunic, and to be silent and keep their eyes lowered when walking in the streets.”
