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.
Martin Knutzen
It was Knutzen who introduced Kant to the scientific literature of the era and especially the works of Isaac Newton, who had such a powerful influence on the development of Kant's own philosophy. Knutzen, however, did not consider Kant to be one of his best students, and favoured (1722–1786) or Johann Friedrich Weitenkampf (1726–1758). Moreover, the name of Kant never appeared in the profuse correspondence between Knutzen and Leonhard Euler, which is evidence of in what little esteem Knutzen held Kant.
