西季威克的伦理思想不仅完善了功利主义,而且还提出了独特的直觉主义伦理思想。而这一崭新的思想又是同他深化亚里士多德的德性伦理学和康德实践伦理学,特别是康德的实践理性直接相关的。因此,在西季威克的伦理思想中,不仅能够看到西方现代伦理学的雏形,而且能看到传统西方伦理思想的深化。从这一意义上说,西季威克是西方传统伦理向现代伦理转变的一个关键人物。 West Timor’s ethics not only perfected utilitarianism, but also proposed a unique ethical thought of intuitionism. And this new thought is directly related to his deepening of Aristotle’s moral ethics and Kant’s practical ethics, especially Kant’s practical rationality. Therefore, in West German ethics, not only can we see the embryonic form of modern western ethics, but also we can see the deepening of traditional Western ethics. In this sense, Sidgwick is a key figure in the transformation from Western traditional ethics to modern ethics.
