It is difficult to comprehend what was lost when our experience of the world became psychologized. The very possibility of revelation is banished. All traffic between the world of the senses and the eternal world comes to a halt. Nullifying thousands of years of mystical experience, Kant declares the thing-in-itself radically unknowable, and in so doing imposes the limit of rational inquiry as the limit of all knowledge. This is the moment the modern world is born.
