Philip Pettit

As the first ontologist, Parmenides has a special place in the history of philosophy, not only because of his originality, but also because of the greatness of his particular attempt in the philosophy of being. His stature is such that any later attempt in the inquiry into being must measure itself against his achievement. His famous philosophical poem, which we have in fragments, is a permanent challenge to later philosophers. Thus Plato could describe Parmenides as ‘a man to be respected and at the same time feared’. And in our own day Martin Heidegger has said that.
