"The only social system that can possibly meet the diverse needs of society, while still promoting solidarity on the widest scale, is one that allows people to freely associate on the basis of common needs and interests. Federalism emphasizes autonomy and decentralization, fosters solidarity and complements groups’ efforts to be as self-sufficient as possible. Groups can then be expected to cooperate as long as they derive mutual benefit. Contrary to the Capitalist and its contracts, if such benefits are not felt to be mutual in an Anarchist society, any group will have the freedom to dissociate. In this manner a flexible and self-regulating social organism will be created, always ready to meet new needs by new organizations and adjustments. Federalism is not a type of Anarchism, but it is an essential part of Anarchism. It is the joining of groups and peoples for political and economic survival and livelihood."
