Plato
The name of one of the greatest Western philosophers is often used as a first name in its land of origin, Greece, and would make a really interesting, thought-provoking choice here. It is remembered here as the nickname of the memorable character played by Sal Mineo in the classic film "Rebel Without a Cause."
And speaking of Greek philosophers, Germaine Clement of Flight of the Conchords named his little boy Sophocles.
