  Yet Moore's casual slide from claims about what we are thinking to the nature of the properties we are attributing in thinking as we do, offered an important point of resistance. As Moore saw things, to make a moral claim is to express a distinctive belief (that might be true or false) about how things are. Specifically, it is to express the belief that some course of action, or institution, or character trait had the property of being right, or good, or virtuous. The challenge (Moore assumed) is to figure out what property it is that we are taking a thing to have, in thinking of it as right, or good, or virtuous. And the place to look, he thought, is at the content of our beliefs.
