The Knower and the Known.

In this paper, I address a dilemma in the theory of knowledge and argue that this dilemma can be overcome by invoking the work of two well known social scientists-Marx (here considered as a sociologist) and Piaget (a psychologist). The dilemma considered is that of the relationship between what are here called "independent" (i.e., non-circular) and "relational" definitions; each form of definition has been the basis of a particular approach to the knowable (the independent definition being the basis of empiricism and the relational definition being the basis of Hegelianism) and each of these approaches can be shown to be unsatisfactory: empiricism, brilliantly successful in practice, runs itself, at the theoretical level, into the circular and the relational; while Hegelianism, although impregnable in logic, gains such impregnability at the cost of any delimitation and, hence of precision and refutability. It is argued that Marx (a follower of Hegel) as adapted by Piaget, can indeed overcome these difficulties and so present us with a theory of knowledge that makes possible an approach that is both successful in practice and reputable in logic.
