Q: Passage: Several German socialists of this period also exhibited anarchist tendencies. The young Wilhelm Weitling, influenced by both Proudhon and Louis Auguste Blanqui, once wrote that "a perfect society has no government, but only an administration, no laws, but only obligations, no punishment, but means of correction." Moses Hess was also an anarchist until around 1844, disseminating Proudhon's theories in Germany, but would go on to write the anti-anarchist pamphlet Die letzte Philosophie. Karl Grün, well known for his role in the disputes between Marx and Proudhon, held a view Nettlau would liken to communist anarchism while still living in Cologne and then left for Paris, where he became a disciple of Proudhon. Wilhelm Marr, born in Hamburg but primarily active in the Young Germany clubs in Switzerland, edited several antiauthoritarian periodicals. In his book on anarchism Anarchie oder Autorität, he comes to the conclusion that liberty is found only in anarchy.
