Abstract

The recent literature has seriously challenged, and in my view defeated, the traditional representationalist interpretation of Descartes. One contributor to it, John Yolton, has recently extended its arguments to argue that the traditional representationalist interpretation of Locke must be relinquished as well, that Locke, following the Cartesian path of Arnauld, held a semiotic theory of ideas which “de-ontologized” them and construed them as signs or cues in the direct perception of physical objects. The Cartesian support for this view, especially in La Dioptrique, has been questioned by R.F. McRae, who argues that “if Locke accepts Descartes' theory of vision, then Descartes' conception of sensations as signs provides no support for the direct realist interpretation of Locke.” My aim here is not to resolve the representationalism issue, but to show the irrelevance to it of the kinds of questions the Yolton-McRae exchange raises concerning sense perception. I shall try to show that there stems from Descartes a single account of those questions the essentials of which are embedded in theories falling on both sides of the representationalism issue. That single account involves a theory of judgment and vision, especially of distance, which in the case of Malebranche and Berkeley, even involves the same confusions.
