This extraordinary book by Elisabeth Tamedly, as scholarly as it is passionate, argues that socialism, despite its internationalist aspirations, is not capable of accomplishing stable international peace and order. If we postulate a true democracy, society is to be built not on centralization, but on federalism and decentralized decision making much as Proudhon had outlined it a century ago. But it is impossible to realize this political order without its economic counterpart: a free market economy based on competition. It was first published in 1969 but has long been unavailable.
