These lectures, entitled the "Addresses to the German Nation", coincided with a period of reform in the Prussian government, under the chancellorship of Baron vom Stein. The "Addresses" display Fichte's interest during that period in language and culture as vehicles of human spiritual development. Fichte built upon earlier ideas of Johann Gottfried Herder and attempted to unite them with his approach. The aim of the German nation, according to Fichte, was to "found an empire of spirit and reason, and to annihilate completely the crude physical force that rules of the world." Like Herder's German nationalism, Fichte's was cultural, and grounded in the aesthetic, literary, and moral.
