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.
Kantian ethics
Biographer of Kant, Manfred Kuhn, suggested that the values Kant's parents held, of "hard work, honesty, cleanliness, and independence”, set him an example and influenced him more than their Pietism did. In the "Stanford Encyclopedia of Philosophy", Michael Rohlf suggests that Kant was influenced by his teacher, Martin Knutzen, himself influenced by the work of Christian Wolff and John Locke, and who introduced Kant to the work of English physicist Isaac Newton.
