Would that be your way of speaking? Yes. 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. Yes. Then knowledge and opinion having distinct powers have also distinct spheres or subject-matters?
