When asked whether or not we are Marxists, our position is the same as that of a physicist, when asked if he is a ‘Newtonian’ or of a biologist when asked if he is a ‘Pasteurian’. There are truths so evident, that it is now useless to debate them. One should be a ‘Marxist’ with the same naturalness with which one is a ‘Newtonian’ in physics.
