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.
Lumières
In Germany, Emmanuel Kant (like Rousseau, defining himself among the Lumières) heavily criticised the limitations of pure reason in his work "Critique of Pure Reason" (), but also that of English empiricism in "Critique of Practical Reason" (). Compared with the rather subjective metaphysics of Descartes, Kant developed a more objective viewpoint in this branch of philosophy.
