"Critique of the Doctrines of Kant and Schopenhauer" (Kritik der Lehren Kant's und Schopenhauer's) is the title of the long appendix to Philipp Mainländer's Die Philosophie der Erlösung (The Philosophy of Redemption). In this appendix, Mainländer offers a criticism of the philosophy of Arthur Schopenhauer. Mainländer saw the purification of Schopenhauer's philosophy as the primary task of his life. The criticism affected Nietzsche's philosophical development.
