moral truths can't be discovered by observation of the world. right and wrong cannot be defined but are self-evident. we can know them by our intuition. it is a moral realist theory believing moral facts/truths actually exist. they are also cognitivist- statements made about right or wrong are subject to being true or false
what do they believe like naturalism?
ethical terms are meaningful. however, they differ from naturalism regarding how moral values come to be known
