  But despite what has been said above, critics of intuitionism can claim that the fact that there is disagreement between moral philosophers and even between intuitionists themselves undermines the view that certain propositions are self-evident. These philosophers will have thought long and hard about the relevant propositions, and (we would hope) have a very clear understanding of them. One would, therefore, expect that if there were certain moral propositions the truth of which could be apprehended by intuition, then moral philosophers would converge on these truths.  Persistent disagreement amongst reflective, thoughtful, and comprehending moral philosophers may cast doubt on the view that any of these propositions are self-evident.
