There are difference to construct the individual well-being between autonomy and authenticity. Autonomy, from Kant’s point of view, its normativity is based on the universal principle of good will. On the contrary, the ethics which base on the Rousseau’s authenticity disagree with any universal and objective moral principle. Therefor the meanings of autonomy and authenticity are not the same. The authenticity ethics tries to fix the problems by Kant’s autonomy. The problems are some moral agents have individual autonomy without authenticity. In other words, agents follow self-imposed principle to do something but they do not truly understand the meaning of these thing. Therefor we should change the meaning of Kant’s autonomy and adding the authenticity to fulfill our moral life.
