For all his fame and influence, none of his books have survived. Indeed, the only thing that has come down the millenia is a single fragment. But for all that, it is a ringing and intriguing statement of belief that has figured in the writings of many of our great philosophers and men of action.

Fate is disconcertingly capricious.
