This book is an attempt at a restatement of the traditional view of the relation of God to man. In opposition to humanism which proposes a religion of pure humanity, and to the theology of crisis which, so to speak, teaches a religion of pure Deity, it maintains a view of religion and theology which holds that the notions of humanity and Deity can not be separated without making them unintelligible. This view makes religion not merely a matter of faith and emotion but of reason as well. The development of this thesis involves looking again at the relation of dogmatic to rational theology and reinterpreting the latter. An examination of the historic proofs for the existence of God and an axiological interpretation of the entire theistic argument constitute the heart of the book. In pursuance of this programme the book includes a study of such topics as language, myth, symbolism, logic, intuition and creed. Finally, after taking up the problems of religious knowledge, it discusses religion and science in contemporary thought, and the relation of religion to the humanities.
