At first sight, Karl Marx and Ludwig Wittgenstein may well seem to be as different from each other as it is possible for the ideas of two major intellectuals to be. Despite this standard conception, however, a small number of scholars have long suggested that there are deeper philosophical commonalities between Marx and Wittgenstein. They have argued that, once grasped, these commonalities can radically change and enrich understanding both of Marxism and of Wittgensteinian philosophy. This book develops and extends this unorthodox view, emphasizing the mutual enrichment that comes from bringing Marx’s and Wittgenstein’s ideas into dialogue with one another.
