In attempting to debunk moral realism through an appeal to evolutionary facts, debunkers face a series of problems, which we label the problems of scope, corrosiveness, and post-hoc justification. To overcome these problems, debunkers must assume certain metaphysical or epistemological positions, or otherwise pre-establish them. In doing so, they must assume or pre-establish the very conclusion they seek in advancing the argument. This means that such debunking arguments either beg the question against the moral realist or are undermined as standalone metaethical arguments.

进化揭穿论证的三个问题

在试图通过诉诸进化论事实来揭穿道德现实主义时，揭穿者面临一系列问题，我们将其标记为范围、腐蚀性和事后证明的问题。为了克服这些问题，揭穿谎言的人必须采取某些形而上学或认识论的立场，或者以其他方式预先确立它们。在这样做时，他们必须假设或预先建立他们在推进论证时寻求的结论。这意味着这种揭穿事实的论点要么回避道德现实主义者的问题，要么被削弱为独立的元伦理学论点。
