German philosophy
Neo-Kantianism refers broadly to the revival of the type of philosophy explained by Immanuel Kant and of the interpretations of Kant provided by post-Kantian philosophers such as Schopenhauer, Jakob Friedrich Fries and Johann Friedrich Herbart. Major figures in the neo-Kantian movement, which began around the 1860s, include Friedrich Albert Lange and Hermann Cohen.
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.
