British philosopher Stephen R.L Clark, well-known for his arguments for Neoplatonism, delivered the Gifford Lectures at the University of Glasgow in 1981. The series of lectures aims to offer a philosophical and rational response to Christian belief. Beginning with an outline of possible responses to the doubts raised by philosophy, which might include a kind of worldly cynicism or relativism, Clark offers a new way forward. Arguing instead that faith and reason are closely interlinked, Clark goes on to argue for the value of truth in lecture three.
