In Latin America we have a saying, “Poner el dedo en la llaga,” a phrase that means to call attention to a delicate or worrisome point. However, llaga means literally an open sore or ulcer. I believe that Cuban socialist and scholar Samuel Farber puts his finger indeed on a significant sore point in revolutionary history with his latest book, The Politics of Che Guevara: Theory and Practice. While recognizing the undeniable determination, egalitarianism, and selflessness of Che Guevara in his fight against imperialism, Farber meticulously exposes the contradictions of Che’s thought and the political, economic, and social detours that Guevara took in his honest quest for a better world.
