罗宾斯在1932年提出了经济学和伦理学的二分,立即被广为接受。从方法论的层面看,罗宾斯观点恰好迎合了当时开始鼎盛的逻辑实证主义哲学。于是,经济学的研究开始以逻辑实证主义的事实与价值的二分法作为方法论基础。而实际情况是,事实理解依赖于价值,价值判断也无法摆脱事实。更加合理的研究框架要求把伦理学的关切和概念引入经济学,而又不牺牲经济学的工程学方面对很多问题提供的合理的解释和有效的分析工具。新的研究框架代表了古典政治经济学复兴和科学哲学发展的潮流。 Robins proposed a dichotomy of economics and ethics in 1932, and was immediately accepted. From a methodological level, Robbins’s point of view catered to the logic positivist philosophy that began its heyday. Thus, the study of economics begins with the dichotomy of the facts and the values ​​of logical positivism as the methodological basis. The fact is that factual understanding depends on value, and value judgments can not get rid of facts. A more rational research framework calls for the introduction of the ethics concerns and concepts into economics without sacrificing the reasonable explanations and effective analytical tools available to many problems in economics. The new research framework represents the tide of the revival of classical political economy and the development of philosophy of science.
