"This is an extremely valuable volume. It gathers in one place material from various sources and makes it accessible to the serious student. The scholarly apparatus--bibliography, short biographies, and introductory essays--makes it especially useful both for the general reader and for teachers in the field. It should make a useful contribution in our struggle for human freedom." --Dennis Brutus, South African poet and revolutionary activist "The power of this book lies in Le Blanc's excellent selection and presentation of some of the most fundamental ideas of Marx, Engels, Lenin, Luxemburg, Trotsky, and Gramsci. His choice of references and the framework for his selection rest on the premise that the central pivot of Marxism is 'proletarian revolutionary practice.'" --Gill Hubbard, International Socialism "The best available tool for revitalizing the consideration of socialist practice in our study groups and classrooms." --Alan Wald, Radical Teacher "A most welcome and needed introduction to Marxist politics from a revolutionary viewpoint .

for students and activists." --Michael Löwy, Monthly Review.
