" He who thinks that the working class can be assured, prosperity and freedom by organizing economic life on a militaristic basis is wrong. No less erroneous is it to strive for a dictatorship for the purpose of crushing the enemy and establishing the working class in a privileged position in the state and society while reducing the rest of the population to the position of pariahs as a means of ultimately establishing socialist equality for all. But most objectionable of all would be to attempt to build a regime of humanity upon the basis of brutality, seeing that without the former no true Socialist commonwealth can exist. For this commonwealth must represent the realization of the slogan of the French Revolution, which was “Liberty, Equality, Fraternity. "
