A Reason for Everything" is a brilliant & surprising fusion of science & biography. It is a very human book about the Englishness of evolutionary theory & the lives & personalities
- often eccentric & controversial
- of those who made it. The idea of evolution by natural selection was first announced in Britain & it has until recently been defended in Britain more passionately than anywhere else. At the heart of the theory is the notion of adaptation to the environment. When 'adaptationists' look at living creatures they believe that each of their features has a purpose for which it has been shaped by selection. They tend to assume that there is actually a reason for everything. & for scientists after Darwin that has been an extremely productive assumption. A number of thinkers developed this idea to levels of sophistication undreamed of in Darwin's time. The most important were Ronald Aylmer Fisher J.B.S. Haldane John Maynard Smith Bill Hamilton & Richard Dawkins. Kohn writes with great insight about the families & the universities that helped shape these men & about their politics which ranged from the far right to the Communist Party. Fisher was a practising Christian; Dawkins is a famously militant atheist. Some were notoriously difficult & eccentric as people; their feuds often were (and are) stormy. He opens the book with a deft & moving portrait of Alfred Russel Wallace Darwin's contemporary & generous rival. "A Reason for Everything" is about far more than a narrow argument within biology. It is about Britain & natural history butterflies & snails impassioned beliefs & ideological struggles. Kohn writes with quiet humour & sympathy about how each of these individuals responded to a chilling & inspiring vision of nature."
