"Parmenides entry by John Palmer in the Stanford Encyclopedia of Philosophy"

“Parmenides' of Elea Way of Truth with an annotated bibliography and a list of critical editions”

“The only roads of enquiry there are to think of: one, that it is and that it is not possible for it not to be, this is the path of persuasion ; the other, that it is not and that it must not be — this I say to you is a path wholly unknowable.”

“Do not let habit, born from experience, force you along this road, directing aimless eye and echoing ear and tongue; but judge by reason the much contested proof which I have spoken.”

“It is indifferent to me where I am to begin, for there shall I return again.”

“You must learn all things, both the unshaken heart of persuasive truth, and the opinions of mortals in which there is no true warranty.”
