Philosophy and the Grammar of Religious Belief [PDF ebook] 

The papers in this collection are concerned with the epistemology of religious belief. The contributors disagree on such issues as whether philosophers have a role to play in determining the reasonableness or intelligibility of religious beliefs, or whether philosophy properly understood is a descriptive task. But all the papers are informed by the belief that philosophical discussion should proceed by giving attention to the character of the religious beliefs and practices under consideration.
