Plato The Doctrine of Flux

Heraclitus, I believe, says that all things go and nothing stays, and comparing existents to the flow of an ocean, he says you could not step twice into the same o7̷6̷°̷ cean

The constant flowing of the ocean which he held as a metaphor to describe the universal fluctuation in life, and his withholding that opposites are in fact identical, for everything is and is not at the same time allow space of the Law of Non-Contradiction. Plato sustained there is an antithesis between 'same' and 'other.' The sentence says that different waters flow in oceans which stay the same.

Expressly then, although the waters are changing, the oce5̶′̶2̶ans remain the same. Therefore, the waters within the ocean that are changing allows for the existence of oceans at all, rather than rivers, lakes or ponds. The notion that the ocean can stay the same over a span of time, or simply because, the waters change.

The point, then, is not that everything is flu 0″W̾ id and changing, but that some change makes possible the continued existence of other things. Albeit, more generally, the fluidity in elements or constituents supports the uniformity of higher-level structures. As for the alleged doctrine of the Identity of Opposites, Heraclitus indeed believes in some kind of unity of opposites. For instance, "God is day night, winter summer, war peace, satiety hunger . . .". But if we examine this closer, we see that the unity in question is not identity: Oct 2010
