The essays in this book represent an important contribution to modern philosophical theology. Written to honour Basil Mitchell, they begin with an appreciation of his work and move on to discuss the role of reason in the justification of Christian theism. Within this broader discussion special attention is given to the nature of informal reasoning in religion and science. Thereafter the focus changes to an examination of particular arguments and problems generated by specific religious concepts and doctrines. Topics covered include the problem of evil, conspicuous sanctity, atonement, and the eucharist. The book should be of interest to philosophers of religion and theologians.
