Plato: The Republic

10. BOOK X (continued)

And this, surely, must be the work of the calculating and rational principle in the soul

To be sure.

And when this principle measures and certifies that some things are equal, or that some are greater or less than others, there occurs an apparent contradiction?

True.

But were we not saying that such a contradiction is the same faculty cannot have contrary opinions at the same time about the same thing?

Very true.

Then that part of the soul which has an opinion contrary to measure is not the same with that which has an opinion in accordance with measure?

True.

And the better part of the soul is likely to be that which trusts to measure and calculation?

Certainly.

And that which is opposed to them is one of the inferior principles of the soul?

No doubt.

This was the conclusion at which I was seeking to arrive when I said that painting or drawing, and imitation in general, when doing their own proper work, are far removed from truth, and the companions and friends and associates of a principle within us which is equally removed from reason, and that they have no true or healthy aim.

Exactly.

The imitative art is an inferior who marries an inferior, and has inferior offspring.

Very true.

And is this confined to the sight only, or does it extend to the hearing also, relating in fact to what we term poetry?

Probably the same would be true of poetry.
