When was Kantian philosophy developed?
Immanuel Kant
Kant also credited David Hume with awakening him from a "dogmatic slumber".[56] Hume had stated that experience consists only of sequences of feelings, images or sounds. Ideas such as "cause", goodness, or objects were not evident in experience, so why do we believe in the reality of these? Kant felt that reason could remove this skepticism, and he set himself to solving these problems. He did not publish any work in philosophy for the next 11 years.
