But how do European railways manage without them? How do they continue to convey millions of travellers and mountains of luggage across a continent? If companies owning railways have been able to agree, why should railway workers, who would take possession of railways, not agree likewise? And if the Petersburg-Warsaw Company and that of Paris-Belfort can act in harmony, without giving themselves the luxury of a common commander, why, in the midst of our societies, consisting of groups of free workers, should we need a Government?

Anarchy, when it works to destroy authority in all its aspects, when it demands the abrogation of laws and the abolition of the mechanism that serves to impose them, when it refuses all hierarchical organization and preaches free agreement - at the same time strives to maintain and enlarge the precious kernel of social customs without which no human or animal society can exist. Only, instead of demanding that those social customs should be maintained through the authority of a few, it demands it from the continued action of all.
