Abstract

There is a paradox, or self-defeating supposition in the core of constructionism, for it would appear that any attempt to resolve a dispute in historical interpretation within a convention of self-contained criteria of confirmation by appealing to justificatory criteria outside the convention -to wit, the theory of constructionism -is self-defeating. Through the theoretical consideration of historians isolated in a vat, following Hilary Putnam's metaphor, it becomes clear that the vat language of the historians does not have the possibility of referring, intrinsically or extrinsically, to anything external. The implications of the vat metaphor for an understanding of historical inquiry are: 1) we need to recognize and insist upon different levels of abstraction both in historical writing and in the justification of its claims; 2) applied to history, the set paradox reveals the need to recognize that at the most abstract level of consideration we encounter inescapable incoherence; and 3) we need to recognize that in some important sense reference must be completed in the world, regardless of the problems in characterizing this sense philosophically
