A very thought provoking book about two perspectives on war - Christianity and Darwinism. Ruse calls on a vast array of scientists, philosophers and theologians from the 1800's to the present. This is a challenging and detailed book but very worth the effort. The author speaks of his Quaker heritage but also references a vast group of Protestant, Catholic and Fundamentalist Christian thinkers. St Augustine is a major source. In science, of course it starts with Darwin but also delves into a wide variety of scientists over the years to the present. Wonderful research. ( )
