This comprehensive collection of essays offers a unique overview of this seminal thinker’s work, showing the development of his thought: from his groundbreaking research on contemporary African politics and social change, to his study of the modern world-system, to his current essays on the new structures of knowledge emerging from the crisis of the capitalist world-economy. His singular focus on the way in which change in one part of the globe affects the whole is all the more relevant as the world grows increasingly interdependent.
