在整个哲学体系中,启蒙是其基本特征,而在对于启蒙的理解中则必然要论及康德,如果要理解康德哲学理论的奥妙,启蒙则是责无旁贷的“密钥”。康德在《回答这个问题:什么是启蒙?》中提出自己的启蒙观,这也是康德哲学的起点与归宿,在其哲学理论的内核中,精髓要义即为:个体的自我启蒙,并且康德还论及了自由运用知性和理性,实现了哲学史上最伟大的哲学思想调和,完成了哲学理念下的思维范式转换,由此可见,自由是康德启蒙哲学的核心。然而,康德的启蒙很难真正得到实践,也是一项未完成的事业,现代和后代思想家对其深剖、积极补充,这也是对康德启蒙哲学的一种继承与发展。本文试图对康德哲学的理解寻求一个新的视角和切入点,探究康德启蒙哲学的理性自由和实践限度,并借用后现代哲学家福柯的“慧眼”提出新的看法,开启启蒙的新定义。 Enlightenment is its basic feature throughout the philosophical system, while Kant must be addressed in its understanding of Enlightenment. Enlightenment is a duty-bound key to understanding the mysteries of Kant’s philosophy. In his answer to this question: What is Enlightenment, Kant put forward his own concept of enlightenment, which is also the starting point and end-result of Kant’s philosophy. The essence of Kant’s philosophy is: the self-enlightenment of the individual and Kant’s theory And the freedom to use intellectual and rational, to achieve the philosophical history of the greatest philosophical reconciliation, completed under the philosophical philosophy paradigm shift, we can see that freedom is the core of Kant’s Enlightenment philosophy. However, Kant’s enlightenment is difficult to really practice, but also an unfinished business, modern and post-modern thinkers to their deep-seated, active supplement, which is also a kind of inheritance and development of Kant’s philosophy of enlightenment. This article attempts to seek a new perspective and entry point for the understanding of Kant’s philosophy, to explore the limits of rational freedom and practice of Kant’s enlightenment philosophy, and to use the postmodernist Foucault’s “wisdom” to come up with new ideas and open new enlightenment definition.
