1, Kant was the last great philosopher in the Enlightenment period and a representative figure in German ideological circles. He reconciled rene descartes's rationalism with Bacon's empiricism, and is regarded as one of the most influential thinkers in the West after Socrates, Plato and Aristotle.

2. A basic starting point of Kant's philosophical theory is that rationality (i.e. category) that transforms experience into knowledge is innate, without which we can't understand the world. His theory combines British empiricism and European rationalism, which has a far-reaching influence on German classical philosophy and romanticism. Kant's moral philosophy theory is also famous.
