In this work I argue that Descartes was not a trialist by showing that the main tenets of trialist interpretations of Descartes's theory of substance are either not supported by the text or are not sufficient for establishing the trialist interpretation.

This paper defends an interpretation of Descartes according to which he sees us as having normative (and not merely psychological) certainty of all clear and distinct ideas during the period in which they are apprehended clearly and distinctly. However, on this view, a retrospective doubt about clear and distinct ideas is possible. This interpretation allows Descartes to avoid the Cartesian Circle in an effective way and also shows that Descartes is surprisingly, in some respects, an epistemological externalist. The paper goes (...) on to defend this interpretation against some powerful philosophical objections by Margaret Wilson and others by showing how Descartes' doctrine of the creation of the eternal truths can be brought in to support his epistemology. This doctrine and other analogous positions in Descartes can also reveal that Descartes, again surprisingly, takes important steps toward doing epistemology without direct appeal to God and God's veracity.

Michel Henry wishes to salvage Descartes’s first principle ‘I think, I am’ by claiming that there is no need to appeal to the world or others to make sense of the self. One of his main targets is Edmund Husserl, who claims that thought is necessarily intentional and thus necessarily about something that is other to thought. To show that this is not so, Henry draws on passages from Descartes’s texts which emphasize that we should not equate the cogito with (...) thinking but with sensation and imagination. This allows Henry to explore the notion that the self has its own form of manifestation. This paper questions Henry’s reading of Descartes and his critique of Husserl on two fronts. First, the passages Henry draws upon, if anything only confirm, rather than question Husserl’s claim that consciousness is intentional. Second, Henry believes that he can show that the life of the self is infinitely rich without having to appeal to other persons or, indeed, to the world. Yet, I wish to contend that Henry is mistaken: as Husserl has shown convincingly, a life without others and the world is not only impoverished and bereft of meaning, but remains entirely indeterminate. The self only manifests itself with respect to others and the world. (shrink)

This paper considers Anselm’s Proslogion argument against a background of historical events that include philosophical disputes between Christian and Jewish polemicists. I argue that the Proslogion argument was addressed, in part, to non-Christian theists and that it offered a response to Jewish polemicists who had argued that the Christian conception of God as an instantiated unity was irrational. Anselm is not trying to convince atheists that there really is a God. He is arguing that the Christian conception of God is (...) logically coherent. (shrink)

The late 19th-century Ignorabimus controversy over the limits of scientific knowledge has often been characterized as proclaiming the end of intellectual progress, and by implication, as plunging Germany into a crisis of pessimism from which Liberalism never recovered. My research supports the opposite interpretation. The initiator of the Ignorabimus controversy, Emil du Bois-Reymond, was a physiologist who worked his whole life against the forces of obscurantism, whether they came from the Catholic and Conservative Right or the scientistic and millenarian Left. (...) Du Bois-Reymond’s doubt that scientists would ever elucidate consciousness must therefore be seen as an endorsement, and not a rejection, of his faith in reason. (shrink)
