Describes the notion of warrant as that which distinguishes knowledge from true belief. This volume examines warrant's role in theistic belief, tackling the questions of whether it is rational, reasonable, justifiable, and warranted to accept Christian belief and whether there is something epistemically unacceptable in doing so. The book is full of philosophical and theological interest and is an exciting book to read... Throughout the book the writing is clear and entertaining, parts of it written with a controlled passion and enthusiasm, and with hafts of sarcasm, self-deprecation and other assorted humour. Plantinga has command of a vast range of philosophical and theological material.
