[P]ossibly... Parmenides believed in a "philosophic life" (§ 35), and... got the idea from the Pythagoreans; but there is very little trace... of his having been... affected by the religious side of Pythagoreanism. ...[T]here are traces of Orphic ideas in the poem ...Parmenides was a western Hellene, and he had probably been a Pythagorean, so it is not a little remarkable that he should be so free from the common tendency of his age and country. ...[L]ike most of the older philosophers, he took part in politics; and recorded that he legislated for his native city. Others add that the magistrates of Elea made the citizens swear every year to abide by the laws which Parmenides had given them.
