‘Scepticism, Relativism, and Religious Knowledge’ shows where responses to scepticism and relativism by Karl Barth and Reformed epistemology have led to impasses, and reconstructs their insights in a robust response that does not depend on making excessive claims about our epistemic capacities. This response is based on a nuanced conception of the relationship between trust, doubt, faith, and reason, and a Kierkegaardian perspective on religious knowledge that stresses the role of the will and the intellectual and theological virtues. This book will appeal to those with an interest in the deep, and often difficult, questions of religion and philosophy, particularly regarding matters of truth, doubt and belief.
