"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."
