from Critical Essays in Marxism
Quite often Marx's language lacks precision, for he does his utmost to embrace the totality of the historical movement all at once, and to consider it in all its complexity. The rigid limits of scientific definitions are not well suited for the expression of a multiform thought which professes to correspond to the infinity of human actions. The Marxists have written much maintaining that the mode of production determines the mode of distribution and exchange. The words which Marx used to express the analogy between the economy and nature certainly have contributed in large measure to developing the fatalist illusion, above all through the use of the term "necessary". Idealism and determinism produce a fictitious and deceptive continuity. Marx teaches us to seek historical continuity in what is truly real— that is, in men furnished with the means to act upon nature.
