Johann Gottlieb Fichte and German Idealism.
This is a lithograph of Johann Gottlieb Fichte (1762-1814), a German philosopher born roughly forty years after Kant who was hugely influenced by Kant’s philosophy. Fichte presents one of three philosophers who are usually seen as representatives of a philosophical movement called “German Idealism,” which emerged in the 1780s and 1790s out of Kant’s work. The other two famous German idealists (besides Fichte) were Friedrich Schelling, and Georg Wilhelm Friedrich Hegel. You can find a good introduction to German idealism here.
