The acclaimed scholars contributing to this volume place under scrutiny a fascinating alternative proposal for a pathway to religious tolerance – that serious consideration of religious diversity tends to reveal the weakness of support many have for their religious commitments, and the humility produced tends to result in religious tolerance. The authors illuminate the debate within philosophy about the way beliefs are supported, the controversy between internalism and externalism, and disagreement about how humility and tolerance are related. Critical and supportive views are represented so that the main lines of agreement and disagreement rise to the surface and are mapped out for the first time. The collection honours Philip Quinn who advocated the pathway so rigorously that the special attention given to his views focuses and deepens the critical discussion. Original essays by some of the most respected contemporary intellectuals in this field make this collection especially attractive.
