Abstract: Kant's doctrine of the Highest Good is always neglected or misunderstood by many researchers.Through the display of the function of the highest good in Kant's ethics,epistemology,history and religion, his article tries to argue that,as the synthetical unification of happiness and virtue,nature and freedom,theory and practice,and experiential world and intelligible world,the highest good not only shows the final end of Kant's critical philosophy,but also has the orientating action to it.

Key words: Kant, the highest good, critical philosophy, orientating action

摘要： 至善学说在康德批判哲学中的地位和作用经常遭到研究者的忽视或误解。事实上,至善作为幸福与德性、自然与自由、理论与实践以及感性世界与理智世界的综合统一,对康德伦理学、认识论、历史观和宗教学说中都具有重要的范导意义。至善不但体现了康德批判哲学的最终目的,而且对批判哲学体系的最终建立具有定向作用。
