20世纪初，直觉主义者摩尔以“开放性问题”的论证来反对自然主义用自然性质给“善”下定义，主张“善”只能靠直觉去把握。但因为“直觉”难以言明，所以不能彻底驳倒自然主义。其后的非认知主义者黑尔通过揭示道德语言的用法，强调评价功能是道德语言的特殊性，为“开放性问题”的论证提供新辩护。作为应对，自然主义者既通过“性质综合同～性定义”的理论继续反驳该论证，又揭示了非道德语词也可能具有的评价功能，回应了非认知主义的批评，以新自然主义的方式再度复兴。在关于“开放性问题”论证的长期争论过程中，西方元伦理学的各流派此起彼伏，纷至沓来，形成了西方元伦理学百家争鸣的局面。全面把握上述论争和走向，对于国内元伦理学的发展具有借鉴意义。

In the early 20th century, Moore, a representative figure of intuitionalism, refuted the naturalistic practice of defining ＂good＇according to natural properties with the ＂open question＇; argument, and proposed that ＇ good＇ can only be attained by intuition. Subsequently, Hare, a non - cognitivist, provided a new vindication for this argument by clarifying through his research on the usage of moral language that the particularity of moral language lies in its evaluative function. In response, the naturalists presented new points of view： on the one hand, they continued to raise counter - arguments on the theoretical basis of ＂synthetically identified moral and natural properties＂; on the other hand, they responded to the non - eognitivist criticism by explicating the possible evaluative funetion of non - moral language, which brought about a revival in the form of neo - naturalism. It is during the long - standing heated debate over the open question argument that diverse schools of thought came into being in the field of meta - ethics, and underwent ups and downs, which results in the general trend of contending currents coexisting in contemporary western meta - ethics.
