We see now that infringement of freedom is necessary with regard to the opponents of the revolution. At a time of revolution we cannot allow freedom for the enemies of the people and of the revolution. That is a surely clear, irrefutable conclusion.
Programme of the World Revolution (1918), Ch. VII
