The great good fortune that reason enjoys by means of mathematics leads entirely naturally to the expectation that, if not mathematics itself, then at least its method will also succeed outside of the field of magnitudes, since brings all its concepts to intuitions that can give a priori and by means of which, so to speak, it becomes master over na ture; while pure philosophy, on the contrary, fumbles around in nature with discursive a priori concepts without being able to make their real ity intuitive a priori and by that means confirm it.
