Two cores of Kant's philosophy, first, humility. Second, the humanistic spirit. In the most negative place, he found the most practical enthusiasm for mankind. The success of Kant's philosophy lies in his recognition of his own limitations, and on this basis, he left a place for that infinite and eternal thing. He paid two prices for this, dualism and agnosticism. But what is priceless in this world? What is perfection? Just as our human nature itself is imperfect, Kant's philosophy is a philosophy of human nature in the final analysis. So no matter how inclusive Hegel's system is, how to justify it. Philosophy will lose its soul if it lacks these two things.

Two core questions of Kant's philosophy: Why is human knowledge universal? How is freedom possible (mathematics and natural science)? In particular, his answer to the second question almost established his immortal position in the history of human thought. At the cost of dualism and agnosticism, he once again put freedom and morality above science and value rationality above instrumental rationality. On this basis, he rebuilt human dignity. No matter how postmodern philosophy deconstructs previous philosophy, Kant is a mountain that they can never cross. He predicted the future of mankind before the problem of human modernization was obvious, and made a solution.

Kant is doomed to be immortal. He is the soul of modern western civilization. Especially for us in China, his thoughts are the most enlightening.
