This is a book with a positive message for a negative world. It is about the spiritual dimension of human experience. In it a precise thinker examines the ways in which we come to know; through science, religion, spirituality, philosophy, through faith, imagination and direct experience. This book examines the various pathways to spiritual understanding, provides sound and convincing arguments for any believer who also respects science, and explains why it is possible for various religions to co-exist peacefully. This is a hopeful, encouraging, and above all mature book, with timely news for a world convinced of its growing sophistication yet constantly displaying its deep anxiety and essential banality. This is a work with a beginning, middle and an end by a practical man of deep faith and unshaken conviction.
