As scholarly interest in the experience of French Maoism has been undergoing something of a renaissance, it is unsurprising that the Maoist practice of investigations has elicited varying degrees of attention in recent years. But this attention has tended to be subsumed within, if not overshadowed by, much broader historical and exegetical undertakings. This paper seeks to redress this limitation in the literature by focusing on the lengthiest and most detailed summary of Maoist investigations among peasants in the French countryside,The (...) Book of Poor Peasants, published by Alain Badiou’s Group for the Foundation of the Union of Communists of France Marxist-Leninist in 1976. This book vividly demonstrates the difficulties and limitations associated with the practice of investigations. It thus affords a more critical appreciation of this practice. The book also casts Badiou’s shift toward a ‘politics without party’ in a new light. (shrink)
