“It is clearly the result, not of carelessness but of matured judgement of our age, which will no longer rest satisfied with the mere appearance of knowledge. It is, at the same time, a powerful appeal to reason to undertake anew the most difficult of its tasks, namely that of self-knowledge, and to institute a court of appeal which should protect reason in its rightful claims, but dismiss all groundless pretensions, and to do this not by the means of despotic decrees but according to the eternal and unalterable laws of reason. This court of appeal is no other than the critique of pure reason itself.”
