“After all, if there is no class stratification in a society, it follows that there is no state, because the state arose as an instrument to be used by a particular class to control the rest of society in its own interests.”

"The Criminality of the State" in American Mercury (March 1939) http://alumnus.caltech.edu/~ckank/FultonsLair/013/nock/criminality.html
Context: The State's criminality is nothing new and nothing to be wondered at. It began when the first predatory group of men clustered together and formed the State, and it will continue as long as the State exists in the world, because the State is fundamentally an anti-social institution, fundamentally criminal. The idea that the State originated to serve any kind of social purpose is completely unhistorical. It originated in conquest and confiscation—that is to say, in crime. It originated for the purpose of maintaining the division of society into an owning-and-exploiting class and a propertyless dependent class — that is, for a criminal purpose.
No State known to history originated in any other manner, or for any other purpose. Like all predatory or parasitic institutions, its first instinct is that of self-preservation. All its enterprises are directed first towards preserving its own life, and, second, towards increasing its own power and enlarging the scope of its own activity. For the sake of this it will, and regularly does, commit any crime which circumstances make expedient.

On Practice (1937)

L'éducation est une monstruosité lorsqu'elle est inégale, lorsqu'elle est le patrimoine exclusif d'une portion de l'association; puisqu'alors elle devient la main de cette portion, un amas de machines, une provisions d'armes de toutes sortes, à l'aide desquelles cette première portion combat l'autre qui est désarmé.

The Book of the New Moral World (1836-1844)
Context: It is the interest of the individual and of all society, that he should be made, at the earliest period, to understand his own construction, the proper use of its parts, and how to keep them at all times in a state of health; and especially that he should be taught to observe the varied effects of different kinds of food, and different quantities, upon his own constitution. He should be taught the general and individual laws of health, thus early, that he may know how to prevent the approach of disease. And the knowledge of the particular diet best suited to his constitution, is one of the most essential laws of health.

Anarchism And Other Impediments To Anarchy (1985)
Context: Every organization has more in common with every other organization than it does with any of the unorganized. The anarchist critique of the state, if only the anarchists understood it, is but a special case of the critique of organization. And, at some level, even anarchist organizations sense this.
Anti-anarchists may well conclude that if there is to be hierarchy and coercion, let it be out in the open, clearly labeled as such. Unlike these pundits (the right-wing "libertarians", the minarchists, for instance) I stubbornly persist in my opposition to the state. But not because, as anarchists so often thoughtlessly declaim, the state is not "necessary". Ordinary people dismiss this anarchist assertion as ludicrous, and so they should. Obviously, in an industrialized class society like ours, the state is necessary. The point is that the state has created the conditions in which it is indeed necessary, by stripping individuals and face-to-face voluntary associations of their powers. More fundamentally, the state's underpinnings (work, moralism, industrial technology, hierarchic organizations) are not necessary but rather antithetical to the satisfactions of real needs and desires. Unfortunately, most brands of anarchism endorse all these premises yet balk at their logical conclusion: the state.
If there were no anarchists, the state would have had to invent them. We know that on several occasions it has done just that. We need anarchists unencumbered by anarchism. Then, and only then, we can begin to get serious about fomenting anarchy.

What is Art? (1897)
Context: In the upper, rich, more educated classes of European society doubt arose as to the truth of that understanding of life which was expressed by Church Christianity. When, after the Crusades and the maximum development of papal power and its abuses, people of the rich classes became acquainted with the wisdom of the classics and saw, on the one hand, the reasonable lucidity of the teachings of the ancient sages, and on the other hand, the incompatibility of the Church doctrine with the teaching of Christ, they found it impossible to continue to believe the Church teaching.
