“义务”概念在康德实践哲学中居于一个重要的位置,可以说康德正是继承了这个传统概念,经过全新的理论阐释,将其作为达到至善理想的途径,以区别于他的主要理论对手——功利主义。康德全新的“义务”概念获得了不可忽视的理论成果,但是我们也可以从这个概念及其论证看到他和对手分享了很多理论前提。正是从两者的异同出发可以更好地理解康德哲学的意义。 The concept of “obligation” occupies an important place in Kant’s philosophy of practice. It can be said that Kant inherited this traditional concept and used a new theory to interpret it as a way to achieve the ideal of good and the difference from his main Theoretical opponent - utilitarianism. Kant’s new “obligations” concept has gained undeniable theoretical results, but we can also see from this concept and his argument that he and his opponent share many theoretical premises. It is from the similarities and differences between the two that a better understanding of Kant’s philosophy can be made.
