Euclid
of Megara
(4th
century BC)
Philosopher
and disciple of Socrates who founded the school of Megara.
Euclid used Socrates thesis that virtue is knowledge while the universe is
changeless and can only be understood through philosophy.
He was said to have found Socrates teachings so interesting that even though
full blown war was going on he disguised himself as a woman and walked 40
kilometres to Athens everyday to listen to him, returning the same way in
the evening.
