Book excerpt: 'The Value of Radical Theory' explains Marx's economic theory, providing the reader with a solid foundation of his critique on capitalism, and also offers insights and a framework where anarchists might learn aspects of Marxist theory while remaining anarchists. This erudite primer sidesteps the typical anarchist vs. Marxist debates, presenting Marx's theory as an enduring explanation of contemporary capitalism, one that will aid in the task of overcoming the market and ushering in an era of participatory control of the economy inspired by anarchist ethics.
