Communism is a society without money, without a state, without property and without social classes. People come together to carry out a project or to respond to some need of the human community but without the possibility of their collective activity taking the form of an enterprise that involves wages and the exchange of its products. The circulation of goods is not accomplished by means of exchange: quite the contrary, the by-word for this society is "from each according to their abilities, to each according to their needs". With communism the government of people gives way to the administration of things. Contrary to the illusion produced by the present society the state and its institutions are not the inevitable result of the growth and complexities of societies, but the opposite, the result of the frantic socialisation of the species without community. The necessity for distinct organs of administration, repression and assistance has its cause in the maintenance of class society. The state is the defender of the dominant class which is increasingly integrated into it. It is forced to alleviate destitution which is increased by a social life where man becomes a predator for man. With communism the oppositional but complementary relationship between the political and economic spheres disappears, i.e. between the citizen supposedly governing society in freedom and equality, and the producer as a slave to material necessity, hierarchy and the despotism of the factory. Communist theory and struggle are a critique of economy and politics.
