Expressivism is supposed to have an advantage over moral realism, in that it can explain why it is a conceptual truth that the moral supervenes on the natural, even though the natural does not entail the moral. I develop an analogy between expressivism and a version of theistic moral realism, and argue that this version of theistic moral realism shares any advantage that expressivism might have. It may be that the alleged advantage that expressivism has over moral realism is overstated. Nevertheless, possible analogies between expressivism and theistic moral realism have received very little attention in the past, and are worth considering for their own sake.

表现主义被认为比道德现实主义具有优势，因为它可以解释为什么道德超越自然是一个概念上的真理，即使自然并不包含道德。我在表现主义和有神论道德现实主义版本之间进行了类比，并认为这种有神论道德现实主义版本具有表现主义可能具有的任何优势。表现主义相对于道德现实主义的所谓优势可能被夸大了。然而，表现主义和有神论的道德现实主义之间可能的类比在过去很少受到关注，它们本身就值得考虑。
