Gilson on Descartes: "indisciplinatus"

From Ivo Coelho, RORTY’S ANTI-FOUNDATIONALISM AND FIDES ET RATIO :

There should be no difficulty, I think, in agreeing with Rorty’s attack on Cartesian subjectivity. Again, there should be no difficulty in agreeing with Rorty’s attack on the Cartesian search for apodicticity. Rorty quotes Dewey and Wittgenstein to the effect that a natural quest for understanding has been run together, by modern philosophers, with an unnatural quest for certainty. Even more interesting however is Rorty quoting Gilson on Descartes’ unwarranted extension of an excessive ideal of certitude to all spheres: “From the point of view of medieval philosophy, Descartes plays the role of the indisciplinatus – someone who takes pride in insisting, no matter what discipline is in question, on the same degree of certainty, no matter how inappropriate. In a word, Descartes no longer recognizes an intermediary between the true and the false; his philosophy is the radical elimination of the notion of the ‘probable.’”
