The Weapon of Organization is a crucial introduction to Tronti, presenting a variety of never-before-translated texts—personal letters, public talks, published articles. With an incisive and provocative introduction that situates Tronti and highlights his relevance to contemporary political struggle, Anastasi translates and restores key writing from the birth of Italian operaismo—days of street fighting and theorizing for a renewed age of revolution. Tronti’s goal, Anastasi writes, was not to become a revered thinker but to participate in the destruction of capitalist society.
