At once polemical, insightful and thought-provoking, Conceiving God is essential reading for all those interested in the origins of religious thought, and the respective roles of science and religion in contemporary society. Building on the insights and discoveries of his two earlier books, The Mind in the Cave and Inside the Neolithic Mind, cognitive archaeologist David Lewis-Williams explores how science developed within the cocoon of religion and then shows how the natural functioning of the human brain creates experiences that can lead to belief in the supernatural realm.
