In June we published the paper which Fergus Kerr had given at the Upholland Theological Consultation in April, ‘‘The Need for Philosophy in Theology Today” (p. 248—260). In it Father Kerr set out to establish his case by assembling examples of the neo-Cartesian presuppositions which he believes still pervade a lot of Western thinking, and Catholic theology especially, but are largely undiscerned. The paper has evoked many and varied reactions, ranging from enthusiastic praise to severe criticism. One of its critics, Father Illtyd Trethowan, discusses it here, and Father Kerr replies.

The issue of New Blackfriars for June 1984 contains the text of Father Fergus Kerr’s address to ‘the gathering which founded the Catholic Theological Association of Great Britain’ in April 1984. A rough summary of his theme might go as follows. Catholic theology is profoundly imbued with ‘a certain Cartesianism’ from which we need to escape (pp. 248—9). Catholic Scholastic philosophy of 25 years ago, based on Aristotle, presents issues which are the subjects of current philosophical debate (although not of current interest to Catholic theologians) and resistance to Cartesianism would have the added advantage of contact with this philosophical debate (pp. 249—52). Catholic theology since Descartes was a struggle to resist Cartesianism, and Aristotelian Thomism was a weapon in the fight; but the battle was lost because the enemy had infiltrated too deeply (pp. 252—3). Examples of Cartesian influence in Catholic theology today are to be found in ‘mentalism in prayer’, ‘interiorist volitionism in moral theology’, a certain approach to human survival after death, Kiing’s presuppositions and Chirico’s epistemology (pp. 253—7).
