从霍布斯对“愚人”问题的阐述和设计,可以看出规范伦理学在发展过程中尝试用美德来修补自身问题,把美德看作主体遵守道德规范的习惯倾向,从而使之成为维持道德体系的有效因素。规范伦理学从狭义上理解的美德不能真实地反映道德生活。相比之下,古典美德理论以美德来定义幸福和价值。事实上,美德更重要的意义在于它是重新看待道德生活的一种视角。 From Hobbes’ s explanation and design of “fools ”, we can see that in the process of development, canonical ethics try to repair its own problems with virtue and regard virtue as the customary tendencies of the subject to abide by ethics so that it becomes Maintain the moral system of the effective factors.
