The mechanists’ outlook might be called negative, while the dialecticians ascribed immense importance to philosophy and regarded themselves as specialists. The mechanists, however, had a much better idea of what science was about. The dialecticians were ignoramuses in this sphere and confined themselves to general formulas about the philosophical need to “generalize” and unify the sciences; on the other hand, they knew more than the mechanists about the history of philosophy. (Eventually the party condemned both camps, and created a dialectical synthesis of both forms of ignorance.) (pg. 64)

But we may safely predict that Marx himself will become more and more what he already is: a chapter from a textbook of the history of ideas, a figure that no longer evokes any emotions, simply the author of one the 'great books' of the nineteenth century - one of those books that very few bother to read but whose titles are known to the educated public.
