Classical

Classical Marxism denotes the collection of socio-eco-political theories expounded by Karl Marx and Friedrich Engels. As Ernest Mandel remarked, "Marxism is always open, always critical, always self-critical." Classical Marxism distinguishes Marxism as broadly perceived from "what Marx believed." In 1883, Marx wrote to his son-in-law Paul Lafargue and French labour leader Jules Guesde —both of whom claimed to represent Marxist principles—accusing them of "revolutionary phrase-mongering" and denying the value of reformist struggle. From Marx's letter derives Marx's famous remark that, if their politics represented Marxism, ' ce qu'il y a de certain c'est que moi, je ne suis pas Marxiste ' ('what is certain is that I myself am not a Marxist')."
