The distinguished American philosopher Alvin Plantinga has had a career-long interest in the defense of Christian belief. There hasn't been a major contemporary challenge to such belief that Plantinga has not, in some way, addressed. This book draws together those contributions, highlighting particularly Plantinga's groundbreaking work in the areas of epistemology and the problem of evil. Historical and biographical background information is included to give perspective to Plantinga's work. His theory that both theistic and Christian belief is warranted and basic is explored and critiqued, and an assessment is offered as to the significance of Plantinga's work for apologetic theory and practice.
