Sperber’s aim is to present Marx as he actually was—a nineteenth-century thinker engaged with the ideas and events of his time. If you see Marx in this way, many of the disputes that raged around his legacy in the past century will seem unprofitable, even irrelevant. Claiming that Marx was in some way “intellectually responsible” for twentieth-century communism will appear thoroughly misguided; but so will the defense of Marx as a radical democrat, since both views “project back onto the nineteenth century controversies of later times.”
Certainly Marx understood crucial features of capitalism; but they were “those of the capitalism that existed in the early decades of the nineteenth century,” rather than the very different capitalism that exists at the start of the twenty-first century. Again, while he looked ahead to a new kind of human society that would come into being after capitalism had collapsed, Marx had no settled conception of what such a society would be like. Turning to him for a vision of our future, for Sperber, is as misconceived as blaming him for our past.
