On the one hand we have man's obstinate faith in the existence of God - a faith so powerful that, as Voltaire said, If God did not exist, it would be necessary to invent him.
Against this stands the evidence of modern science - physics, biology, cosmology - explaining in its own terms the universe and the presence within it of life. With their observations on human thinking and behaviour, psychology and philosophy frequently confirm the findings of science.
In this volume Alan Isaacs reviews the opposing cases. For many he sees religious faith as a private necessity: for society as a whole, even in the nuclear age, he acknowledges that the concept of God may serve a useful function in the enforcement of moral codes. And if his conclusion is a frank, I don't know, his path to it follows the profoundest issue of this, or any, age through the whole spectrum of twentieth-century thought.
Discusses the origin of and effects of religion in the context of human evolution in a very clear and concise manner. While bits and pieces of the book (written in the sixties) are possibly somewhat outdated I still feel that I gained a lot of insight and clarity from reading it. It certainly provides a useful way of thinking about the problem, and summarises scientific findings from various disciplines on the subject.
