Moral judgments may conflict with one another. Two conflicting moral judgments cannot both be right. This does not mean that the moral intuition itself is subject to error, but merely that we may fail to disentangle the intuition itself from irrelevances, or may unconsciously pretend to have an intuition when we actually have it not. The intuition itself is infallible; but we can never be sure that we have it, or that we have not confused it, or expressed it falsely in words. In the same way sense-experience is infallible, but we may unconsciously pretend to have it when we have, it not, and we may misdescribe it, and so on.
