Euclid

Euclid of Megara, a Greek philosopher, who has often been confounded with the mathematician of the same name. He was one of the chief disciples of Socrates, but had previously studied the dialectics of the Eleatics; on one occasion Socrates declared that his pupil's subtle logic might win sophists, but never men. After the death of his master (399 B.C.), Euclid established a school of his own, which received the name of the Megaric School. The basis of his system was the Eleatic dogma of a one, only, universal existence; and, blending with this the Socratic idea of the predominance of the moral element, Euclid held this one real existence to be the Good, though it receives various names under its special manifestations.
