Quote from Voltairine de Cleyre

"There are, accordingly, several economic schools among Anarchists; there are Anarchist Individualists, Anarchist Mutualists, Anarchist Communists and Anarchist Socialists. In times past these several schools have bitterly denounced each other and mutually refused to recognize each other as Anarchists at all. The more narrow-minded on both sides still do so; true, they do not consider it narrow-mindedness, but simply a firm and solid grasp of the truth, which does not permit of tolerance towards error. This has been the attitude of the bigot in all ages, and Anarchism no more than any other new doctrine has escaped its bigots. Each of these fanatical adherents of either collectivism or individualism believes that no Anarchism is possible without that particular economic system as its guarantee, and is of course thoroughly justified from his own standpoint. With the extension of what Comrade Brown calls the New Spirit, however, this old narrowness is yielding to the broader, kindlier and far more reasonable idea, that all these economic ideas may be experimented with, and there is nothing un-Anarchistic about any of them until the element of compulsion enters and obliges unwilling persons to remain in a community whose economic arrangements they do not agree to." ~ Voltairine de Cleyre
