The basic principles of anarchism— self-organization, voluntary association, mutual aid— referred to forms of human behavior they assumed to have been around about as long as humanity.
The same goes for the rejection of the state and of all forms of structural violence, inequality, or domination, even the assumption that all these forms are somehow related and reinforce each other. None of it was presented as some startling new doctrine. And in fact it was not: one can find records of people making similar arguments throughout history, despite the fact there is every reason to believe that in most times and places, such opinions were the ones least likely to be written down. We are talking less about a body of theory, then, than about an attitude, or perhaps one might even say a faith: the rejection of certain types of social relations, the confidence that certain others would be much better ones on which to build a livable society, the belief that such a society could actually exist.
