Critique of the Kantian philosophy
"Critique of the Kantian philosophy" is a criticism Arthur Schopenhauer appended to the first volume of his "The World as Will and Representation" (1818). He wanted to show Immanuel Kant's errors so that Kant's merits would be appreciated and his achievements furthered.
Józef Kalasanty Szaniawski
Szaniawski especially urged the study of Kant; but, having accepted the fundamental points of the critical theory of knowledge, he still hesitated between Kant's metaphysical agnosticism and the new metaphysics of Idealism. He owed a particular debt to Schelling. Thus this one man introduced to Poland both the anti-metaphysical Kant and the post-Kantian metaphysics.
