MacIntyre Says

"Twentieth-century moral philosophers have sometimes appealed to their or our intuitions; but one of the things that we ought to have learned from the history of moral philosophy is that the introduction of the word 'intuition' by a moral philosopher is always a signal that something has gone badly wrong with an argument."
