Karl Marx was the greatest champion of the labor theory of value. The logical problems of this theory have, however, split scholars of Marx into two factions: those who regard it as an indivisible component of Marxism, and those who wish to continue the spirit of analysis begun by Marx without the labor theory of value. In the debate between these two camps, the former has attempted to draw support from Marx's concepts of value, while the latter has ignored them, taking instead as their starting point the truism that production generates a surplus. Nevertheless, a careful examination of the development of Marx's logic uncovers the profound irony that, after a chance rereading of Hegel, Marx made a crucial advance which should have led him to replace the labor theory of value with the theory that commodities in general are the source of surplus. Marx's value analysis is thus consistent, not with those who would defend the labor theory of value, but with those who would transcend it.
