In this article, I have tried to consider and criticize the most important
principle of Kant"s ethical theory. According to his theory of ethics, man as a
moral agent, is autonomous, that is to say, his reason is self-legislative. This
means that man is under no obligation to obey the laws of another, not even
the laws of God. For him, Man"s own cohscience is the highest moral tribunal.
My contention in this paper is that, in spite of this, in some of his writings we
can find some remarks inconsistant with what he officially adheres to.
I will show that in his ethical theory Kant has, in fact, moved from his
early view of self-legislation into a more common view of self-obligation.
