 Ross’s more restricted conception of self-evidence has another potential advantage. We were all taught about morality. When children, we were told, “Don’t hit!” “Share your toys”, “You ought not lie”, etc. And when older, most of us encountered situations where it was not clear to us what we should do, so we sought the advice of someone we trusted. In some of these cases the moral propositions at issue may have been self-evident, but at first the truth of these propositions was not obvious to us, so we believed on the basis of testimony. One might address these moral cases in the way we’ve suggested the standard story could address analogous logical and mathematical cases. That way of addressing the cases is not obviously mistaken, but one might balk at the thought that a person who understands a self-evident proposition automatically has a justification for that proposition even before it is apparent to the person that the proposition is true.
