Kant's Three Criticism

Kant's most famous works are his three criticisms-criticism of pure reason, criticism of practical reason and criticism of judgment, which constitute the core content of his whole philosophical system. His theory deeply influenced modern western philosophy and opened many schools such as German idealism and Kantism.

"There are two things. The deeper and longer I think about them, the more amazing and awe they arouse in my mind. This is the starry sky above my head and the moral law in my heart. " This famous saying comes from the last chapter of Kant's Critique of Practical Reason and is also engraved on Kant's tombstone.

Kant's philosophy focuses on the discussion of human nature, and the main theoretical achievements are in three aspects:

(1) Critique of Pure Reason: It is a discussion about people's cognitive ability, laying a foundation for scientific knowledge and solving epistemological problems, that is, knowledge problems (theoretical rationality).

(2) Criticism of practical reason: the discussion of people's desire ability, the study of people's moral principles and their basic free will, that is, the significance of solving moral philosophy problems (practical reason).

(3) Critique of Judgment (the link between theoretical rationality and practical rationality): The discussion of human emotional ability is embodied in aesthetics and teleology, that is, emotional topics and emotions.

Kant once said that all his philosophical research is ultimately to solve "what is man?" This problem consists of three sub-problems. The above-mentioned "three criticisms" are a philosophical panorama around this universal problem.

① "What can we know?" A critique of pure reason to solve.

② "What should we do?" A "practical rational criticism" to solve.

③ "What do we hope to do?" A "judgment criticism" to solve.
