“人是目的”是康德伦理学的一个重要命题,构成了整个伦理学系统的基础。人是唯一具有理性的动物,理性决定了人之为人和人的道德价值,理性以自身为目的,而人作为理性存在者,本身就构成了自身的目的,但是康德并没有完全否定人作为手段的一方面,他用意志自律来达到了两者的统一。人的意志自律,也就是自由,自由是人的本质,人有了自由才使道德成为可能。 “Man is the purpose ” is an important proposition of Kant’s ethics, which forms the basis of the whole ethics system. Man is the only animal with rationality, rationality determines the moral value of human beings and human beings, and rationality regards himself as his purpose.

Human will self-discipline, that is, freedom, freedom is the essence of human beings, freedom has made moral possible.
