The first thing anyone knows about me (thanks to Plato) is that at age 40, I went to Athens to meet with a young Socrates.
Though originally a Pythagorean, I eventually led a Eleatic school near Crotona, a philosophical school that challenged Pythagoras' claim that all can be represented by whole numbers.
My claim to fame is the posing of four paradoxes regarding the reality of motion, with the most famous involving a race between Achilles and a tortoise.
My paradoxes basically led to the study of infinite processes in geometry....plus unleashing the quandry of infinity itself.
Folklore suggests that I was eventually tortured and killed by a tyrant of Elea, who I had supposedly plotted to depose.
