Review by Judith Shulevitz (author of "The Sabbath World: Glimpses of a Different Order of Time"): Wade asserts "the God gene" & its evolutionary function - "to bind human beings into cooperative groups," making altruism, group (over self-) interest & solidarity a matter of conscience (with the gods as enforcers). Shulevitz's criticism is "that he has under-ambitiously portrayed religion as less encompassing and consequential than it is."
