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.
Joseph Green (merchant)
Around 1764 Green met Kant and became a close member of his circle of friends. Kant went often to Green's house outside of Königsberg in Juditten. Green shared with Kant a deep appreciation of the ideas of David Hume and Jean-Jaques Rousseau, in addition, Green could provide as perspective of the outside world that was helpful for Kant. Meeting on a regular basis, Kant discussed his work with him, so every sentence of his "Critique of Pure Reason" prior to the 1781 publication. Kant also entrusted Green with his money.
