It will come as no surprise that I have a different interpretation of the four passages in which, McRae claims, Descartes “definitely includes extension and its modes in what is given through the senses”. In the first, Descartes includes extension, etc., among his ideas of corporeal bodies. This is not to say that he includes them among his adventitious ideas, though. All adventitious ideas are ideas of external bodies. But the converse is not true. Not all ideas of corporeal bodies are ipso facto adventitious ideas, for, as I see it, the idea of the true and immutable nature of body is non-sensible and innate. McRae slides from “all adventitious ideas seem to be ideas of external bodies” to “all ideas of external bodies (including extension) are adventitious”.

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.

In Harris v. McRae, the recent case in which the U.S. Supreme Court upheld the constitutionality of the Hyde Amendment, the Court for the first time was asked to consider whether antiabortion legislation respects the establishment of religion or violates the free exercise thereof. The Court held that the Amendment did not effect an establishment of religion, and found that the plaintiffs lacked standing to raise the free exercise argument.

The writer explores the questions raised, agreeing with the Court's disposal of the establishment argument. He does find considerable.validity in the free exercise challenge, but concludes that the Court as presently constituted is unlikely to accept it. In addition, he believes that the Court, in its treatment of both arguments, either ignored or improperly dis tinguished earlier cases that supported the plaintiffs.
