Foundationalism is the view that philosophical propositions are of two kinds, those which need supporting evidence, and those which in themselves provide the evidence which renders them irrefutable. This book, originally published 1988, describes the battle between foundationalism, which places belief in God in the first category, and various other approaches to the problem of faith - 'Reformed Epistemology', hermeneutics; and sociological analysis. In the concluding section of the book, an examination of concept formation in religious belief is used to reinterpret the gap between the expressive power of language and the reality of God.
