Possibility and Competence

Yes, "if men were what they should be, could be, if all men were rational, all loved each other as brothers," then it would be a paradisiacal life. -- All right, men are as they should be, can be. What should they be? Surely not more than they can be! And what can they be? Not more, again, than they -- can, than they have the competence, the force, to be. But this they really are, because what they are not they are incapable of being; for to be capable means -- really to be. One is not capable for anything that one really is not; one is not capable of anything that one does not really do. Could a man blinded by cataracts see? Oh, yes, if he had his cataracts successfully removed. But now he cannot see because he does not see. Possibility and reality always coincide. One can do nothing that one does not, as one does nothing that one cannot.
