For a new generation of activists, these are classic revolutionary writings by four famous rebels, including The Communist Manifesto by Karl Marx and Friedrich Engels; Reform or Revolution by Rosa Luxemburg; and Che Guevara's Socialism and Man in Cuba. Includes an introduction by Cuban Marxist intellectual Armando Hart and a preface by US radical poet Adrienne Rich. The essays in this book, Manifesto, were written by three relatively young people - Karl Marx when he was 30, Rosa Luxemburg at 27, Che Guevara at the age of 37. Born into different historical moments and different generations, they shared an energy of hope, an engagement with history, a belief that critical thinking must inform action, and a passion for the world and its human possibilities. Here are urgent conversations from the past that are still being carried on, among new voices, throughout the world.
