  Kant's views on psychology are intimately bound up with his more general position in the philosophy of mind. (See the separate entry on this topic.) Still, one can take note of the fact that Kant distinguishes between rational and empirical psychology and, in the Critique of Pure Reason's Paralogisms, denies that rational psychology contains arguments that could justify any substantive principles (especially concerning our immortality). Thus, only empirical psychology, it seems, could be possible as a science. However, if Kant continues to maintain that science requires a pure part, and denies that rational psychology contains any substantive knowledge that might constitute the pure part of psychology, then it follows that empirical psychology cannot qualify as science proper either.
