Excerpt:
Parmenides, the son of Pyres (or Pyrrhes), of Elea, was born about 515 B.C.; his family was of noble rank and rich, but Parmenides devoted himself to philosophy. He was associated with members of the Pythagorean society, and is himself called a Pythagorean by later writers. In the formation of his philosophic system however he was most influenced by his aged fellow-townsman, Xenophanes; the doctrines of Xenophanes he developed into a system which was embodied in a poetic work "On Nature." The statement that he made laws for the citizens may have reference to some connection with the Pythagorean society.
