The Republic of Plato

by Plato

True.

Of not-being, ignorance was assumed to be the necessary correlative; of being, knowledge?

True, he said.

Then opinion is not concerned either with being or with not-being?

Not with either.

And can therefore neither be ignorance nor knowledge?

That seems to be true.

Its place is not to be sought without or beyond knowledge or ignorance, but between them. But is opinion to be sought without and beyond either of them, in a greater clearness than knowledge, or in a greater darkness than ignorance?

In neither.

Then I suppose that opinion appears to you to be darker than knowledge, but lighter than ignorance?
