And will you be so very good as to answer one more question? Would you say that knowledge is a faculty, or in what class would you place it?

Certainly knowledge is a faculty, and the mightiest of all faculties.

And is opinion also a faculty?

Certainly, he said; for opinion is that with which we are able to form an opinion.

And yet you were acknowledging a little while ago that knowledge is not the same as opinion?

Why, yes, he said: how can any reasonable being ever identify that which is infallible with that which errs?

An excellent answer, proving, I said, that we are quite conscious of a distinction between them.
