"The new society cannot get out of the involucrum of the old society, except by smashing it to pieces; two conceptions, two classes, two worlds will contend for primacy, and only force will compel the weaker to disappear. For this reason, we socialists of the first school, Marxist and catastrophic, if you wish, explain to ourselves the partial violence of to-day and the violence of to-morrow… Do not call us prophets of massacre if we present the possibility that the socialist revolution will have insurrectional episodes. It is puerile to think that such a radical displacement of interests, such a profound transformation of habits can be accomplished without violent conflicts."
