What is meant by this title? Critique is not precisely a criticism, but a critical analysis; Kant is not attacking “pure reason,” except, at the end, to show its limitations; rather he hopes to show its possibility, and to exalt it above the impure knowledge which comes to us through the distorting channels of sense. For “pure” reason is to mean knowledge that does not come through our senses, but is independent of all sense experience; knowledge belonging to us by the inherent nature and structure of the mind.
