The aim of that ＂experiment＂ is to establish ＂an entire revolution＂ in philosophical thinking, which was initiated by the Copernican revolution in cosmology in order to find the secure path, and its possibility application to metaphysics. Kant＇s aim in Critique of Pure Reason is to rescue metaphysics from a ＂blind groping＂ by undertaking a revolution in metaphysics as Copernicus has brought to cosmology. Kant＇s Copernican turn consists in the assertion that the possibility of knowledge requires that ＂the objects must conform to our cognition.＂ From Kant＇s view, we can know only what we ＂construct,＂ ＂make,＂ or ＂produce＂ as a necessary condition of knowledge, but we cannot know the mind--independent external world, i.e., the world which is independent of us. Kant＇s epistemological constructivism is the central point to his Copernican revolution.展开更多
