A surge of interest in the evolutionary basis for religion has resulted in some fine works. Few, however, approach the careful analysis and depth of insight offered by Atran's excellent book. Asking the question, "Why do humans put so many resources into a counterintuitive supernatural world?", he responds that the answers fall easily into an evolutionary framework. He goes on to explain, in ten easy steps[!] how this circumstance has come about. The core of the presentation is what practices we follow are derived from normal, everyday behaviour traits. These traits are human cognitive ones, which makes their biological roots distant but traceable. The human mind, derived from the sudden expansion of cognitive abilities about fifty thousand years ago, put us in a unique position in the animal kingdom. Religion is the price we pay for being "special".
The "ten easy steps" are not. The astute reader may jump to the Conclusion for an outline of Atran's thesis. There he explains that religion is not an "entity", even though we publicly commit resources to it. Since it's not an entity, religion itself cannot be an evolutionary adaptation. However, it does fit into an "evolutionary landscape". That landscape he describes in a metaphor of hills and valleys, with certain behaviours following the path of least resistance. The supernatural, Atran contends, arises from a "cultural manipulation" of habits derived from the Pleistocene - fear of predators, death and the quest for nourishment. Since humans live in groups, the interactions of individuals within the group reinforces these habits. When natural phenomena are transformed into the supernatural conformity results. Once completing the outline, readers will find enlightening and reasoned arguments supporting the thesis that the foundations for religious behaviour have well-established roots.
Atran discusses the distinction between pathological and mystical mental states. While these are useful, his analysis of the sociobiological and "group selection" theses make truly compelling reading. Sociobiology has sought the roots of many human behaviour traits in the actions of other creatures. While that works for some behaviours, Atran sees no justification for applying it to religion. Religion is too human specific, he argues. Nor, he contends, does the notion that "group selection" - which claims religion is a "superorganism" - has any basis. He further dismisses the notion that "memes" - a form of replicable and transmitted idea, cannot account for the persistence of religious ideas. Memes, he finds, require a fidelity of transmission that isn't reflected in reality. Religion, being highly variable across many environments, isn't supportive of such rigid definition.
As a final topic, Atran addresses the dichotomy between religion and science. The underlying distinction between these two social forces is that science recognises that humans are incidental elements in the universe, while religion places them at the centre. Religion fares poorly in knowledge, while science lacks a strong moral element. It's a fitting conclusion to a book closely examining how science has addressed the phenomenon of human belief in the supernatural.
Although Atran's prose style is a bit stiff, the information he conveys is too significant and well thought out to make that objection important. His command of the sources is indicated in the bibliography and carefully shown as presented in the text. He acknowledges in his first note that Pascal Boyer's "Religion Explained" was published as this book was going to press. Any student of causes for human religion will need to carefully study both books. They are a major contributions in understanding why humans engage in such seemingly bizarre practices as religion.
