Decent Essays

Heraclitus argued there was a single divine law of the universe, which rules and guides the cosmos. This is the Logos. He said that the logos both underlies and governs change.

"For you could not know what is not - that is impossible - nor could you express it." (6.5 Robinson) But to think about something and it really existing are two different things. Parmenides sums that thought up by saying, " that which is there to be spoken and thought of must be. For it is possible for it to be, but not possible for nothing to be."
