Book excerpt: “The Evolution of Religion” is exactly what the title suggests, and beyond. It traces religion's origins back to the first instincts of morality, through the archaic blossoming of polytheism, to the modern branching of creeds from the agnostic East to the monotheistic West. It also conducts an in-depth analysis of religion's organic and synthetic qualities. The organic aspect is demonstrated through consistencies between biology and theology, ranging from similarities in their 'tree-of-life' diagrams to specific phylogenetic characteristics. The synthetic facet is showcased through coinciding patterns with such manmade conventions as government, culture, economics, and technology. What isn't clearly revealed is a supernatural quality, prompting us to delve into the psychology behind worship and why many of us are “addicted to faith”.
