L'anarco-individualista Benjamin Tucker ha definito l'anarchismo come opposizione all'autorità nel seguente modo: «They found that they must turn either to the right or to the left, — follow either the path of Authority or the path of Liberty. Marx went one way; Warren and Proudhon the other. Thus were born State Socialism and Anarchism [...] Authority, takes many shapes, but, broadly speaking, her enemies divide themselves into three classes: first, those who abhor her both as a means and as an end of progress, opposing her openly, avowedly, sincerely, consistently, universally; second, those who profess to believe in her as a means of progress, but who accept her only so far as they think she will subserve their own selfish interests, denying her and her blessings to the rest of the world; third, those who distrust her as a means of progress, believing in her only as an end to be obtained by first trampling upon, violating, and outraging her. These three phases of opposition to Liberty are met in almost every sphere of thought and human activity. Good representatives of the first are seen in the Catholic Church and the Russian autocracy; of the second, in the Protestant Church and the Manchester school of politics and political economy; of the third, in the atheism of Gambetta and the socialism of the socialism off Karl Marg».

«That is why 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».
