"Marx called himself a scientist; but he lacked the solid groundwork of facts on which to operate a scientific method. His theories are dogma, true only because he said so; and any study of them is nearer to theology than to science. Mr. Landauer is particularly anxious to show that Marx, though personally assertive, was not a believer in dictatorship in the Stalinist sense; and this is true. Marxism could develop into German social democracy or into Bolshevism, with a certain amount of perversion in each case; neither was more than implicit in Marx's own writings."
