  Moore was quick to point out that granting that the question is open, in the sense his argument supposes, is compatible with discovering that, as a matter of fact, everything that is pleasant is also good. Moore's point is that the question is not settled — not closed — on conceptual grounds (whereas it would be if thinking something good were just a matter of thinking it pleasant).  Because analogous questions remain open for all the candidate naturalist proposals, Moore argued that no such proposal could legitimately be defended as a conceptual truth and that they all failed to capture accurately what we are thinking in thinking of something that it is good.
