Based on Kant's critical philosophy, he put forward that man is an end rather than a means, liberating man from the bondage of simple causal inevitability, and completing the transformation from classical philosophy of law to modern philosophy of law and revolutionary changes in the history of development.

At the same time, Kant deeply discussed the realization and maintenance of human freedom and rights, private law and public law and other legal philosophy issues, and formed a wealth of legal philosophy thoughts, which had a great impact on the development of legal philosophy in later generations.

Kant attached religion to practical reason and established religion and theology from the moral point of view. His religious problems stem from moral problems and the concept of supreme goodness. This is a belief based on rational essence, which determines the inevitability of belief from the moral standpoint, and moral obligation is also the command of God.

By the critical period, Kant's religious thought had been basically perfected. His practical reason also belongs to the system of pure reason in essence, and the problem of belief is an extra disk left by pure reason. Purposeful thinking unifies morality and belief, as well as religion and aesthetics.
