"Dom Illtyd Trethowan takes up the challenge both from the skeptical philosopher who would deny certainty of any sort, and from the over-rigid Thomist who would make faith an act ordered by the will in what seems an obscurant sense. This involves a most radical probing of both modern and traditional epistemology." - publisher.
