Abstract: Goodness has always been the theme of western ethics, and by the late period of German classical philosophy, the concept presented as a feeling of extremely romantic, which Hegel called conscience. Conscience aims to explain the superiority of individual moral behavior, but at the same time, it has no doubt subjectivity. Hagel thought that if an era generally uses conscience as the criterion of action, then conscience will inevitably be alienated into hypocrisy, thus he launched a kind of "goodness-conscience-hypocrisy"dialectical argument.
