我很早就对伦理学问题感兴趣并对现行传统道德深为不满，于是孜孜以求。在写作《寻求新道德》的十年艰辛中，我越发深信：中国需要的既不是西方道德，也不是传统道德，而是为科学的伦理学所确立的优良道德。伦理学能否成为科学，正如摩尔所说，关键在于解决价值与事实的关系。 I was very interested in ethical issues very early and deeply dissatisfied with the existing traditional morality, so I pursued. In the ten years of arduous struggle writing “Seeking New Morality,” I became more and more convinced that what China needs is neither western nor traditional morality, but an excellent moral established for scientific ethics. Whether ethics can become science, as Moore puts it, lies in the solution of the relationship between value and fact.
