"But while anarchism is a broad river, it is possible to discern a number of distinctive currents. What principally divides the family of anarchists is their different views of human nature, strategy and organisation. The mainstream is occupied by the social anarchists, but the individualists form an important part of the flow. Amongst the social anarchists, there are mutualists, collectivists, communists, and syndicalists, who differ mainly on the issue of economic organization. Some may be grouped according to their strategies, like pacifist anarchists. The social anarchists and individualists often work together but bear differing emphases. The individualists see the danger of obligatory cooperation and are worried that a collectivist society will lead to the tyranny of the group. On the other hand, the social anarchists are concerned that a society of individualists might become atomistic and that the spirit of competition could destroy mutual aid and general solidarity. Such differences do not prevent both wings coming together in the notion of communal individuality, which attempts to achieve a maxim um degree of personal freedom without destroying the community." Peter Marshall, 'Demanding the Impossible', page 6 "In the absence of a professional police force, communites are quite capable of maintaining public security for themselves and have done so for centuries." Peter Marshall, 'Demanding the Impossible', p645 Anarcho-capitalists are against the State simply because they are capitalists first and foremost. Their critique of the State ultimately rests on a liberal interpretation of liberty as the inviolable rights to and of private property. They are not concerned with the social consequences of capitalism for the weak, powerless and ignorant. Their claim that all would benefit from a free exchange in the market is by no means certain; any unfettered market system would most likely sponsor a reversion to an unequal society with defence associations perpetuating exploitation and privilege. If anything, anarcho-capitalism is merely a free-for-all in which only the rich and cunning would benefit. It is tailor-made for 'rugged individualists' who do not care about the damage to others or to the environment which they leave in their wake. The forces of the market cannot provide genuine conditions for freedom any more than the powers of the State. The victims of both are equally enslaved, alienated and oppressed." Peter Marshall in "Demanding the Impossible: A History of Anarchism"
