"Zwei gave his wisdom and wisdom a new life, and his morality also gave me."

"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 is one of the most magnificent maxims in the history of human thought. The last chapter of Kant's Critique of Practical Reason is engraved on Kant's tombstone.
