Is nature all there is? John Haught examines this question and in doing so addresses a fundamental issue in the dialogue of science with religion. The belief that nature is all there is and that no overall purpose exists in the universe is known broadly as 'naturalism'. Naturalism, in this context, denies the existence of any realities distinct from the natural world and human culture. Since the rise of science in the modern world has had so much influence on naturalism's intellectual acceptance, the author focuses on 'scientific' naturalism and the way in which its defenders are now attempting to put a distance between contemporary thought and humanity's religious traditions. Haught seeks to provide a reasonable, scientifically informed alternative to naturalism. His approach will provide the basis for lively discussion among students, scholars, scientists, theologians and intellectually curious people in general.
