Plato Parmenides Quotes & Sayings

For Plato, if two individuals have some common attribute and so are describable by the same predicate-'Tom is a man'; 'Dick is a man'-then there is something in virtue of which Tom and Dick (together with all other referents of the predicate nominative 'man') have this common attribute. This something is the ideal Form man, which Form is what really, ultimately exists, whereas individual men are just temporal appearances of the Form, with a kind of borrowed or derivative existence, like shadows or projected images. That's a very simplified version of the O.O.M., but not a distorted one-and even at this level it should not be hard to see the influences of Pythagoras and Parmenides on Plato's ontological Theory of Forms, which the O.O.M. is an obvious part of. — David Foster Wallace

But ought we to give him up? 'I should say, certainly not.' Then I fear that I must lay hands on my father Parmenides; but do not call me a parricide; for there is no way out of the difficulty except to show that in some sense not-being is; and if this is not admitted, no one can speak of falsehood, or false opinion, or imitation, without falling into a contradiction. You observe how unwilling I am to undertake the task; for I know that I am exposing myself to the charge of inconsistency in asserting the being of not-being. But if I am to make the attempt, I think that I had better begin at the beginning. — Plato

To the passionate language of Parmenides, Plato replies in a strain equally passionate:
What! has not Being mind? and is not Being capable of being known? and, if this is admitted, then capable of being affected or acted upon?
in motion, then, and yet not wholly incapable of rest. Already we have been compelled to attribute opposite determinations to Being. And the answer to the difficulty about Being may be equally the answer to the difficulty about Not-being. — Plato

No space, no time, no gravity, no electromagnetism, no particles. Nothing. We are back where Plato, Aristotle and Parmenides struggled with the great questions: How Come the Universe, How Come Us, How Come Anything? But happily also we have around the answer to these questions. That's us. — John Archibald Wheeler
