According to Kant, the freedom to use one’s own reason against traditional authorities can enlighten the public. It should not harm the whole of society and others. One must work for public interests as a member of the community. Kant’s enlightenment generally surveys the ideals of thinking in general rather than considering traditional authorities, or history. In other words, Kant believes that the ideals of enlightenment can be realized in reality. However, people in reality do not live only with the freedom to use one’s own reason. Rather, the world of human habitation and the process of history have inevitably been determined by its own laws. Laws of history is made from universal truth and human free will and acquired experience so, humans can not ignore their experiences while living their lives. I believe that human beings learn the world through experience and also create laws of life. Therefore, unless we try to realize the ideal, the efforts can never be achieved unless it conforms to the historical tide of traditional authorities. Kant says, “Argue as much as you will, and about what you will, but obey!”, and he answers “the public use of one’s reason must always be free, and it alone can bring about enlightenment among men.” These propositions contain Kant’s intention not only to maintain social order, but also to seek social progress through public use of reason. However, contrary to Kant’s position, there is a contradiction in this logic. If humans truly have the freedom to use one’s own reason, an individual can think, blame, criticize, argue and disobey the public.
