Like the Bourbons, Mary Midgley appears to have learnt nothing and forgotten nothing since her review of Richard Dawkins 'The Selfish Gene' in the journal 'Philosophy', 54, 1979. There is no logical link whatever between evolutionary biology/ psychology and what Bishop Butler called 'the selfish theory of human nature' to be found (he claimed) in Thomas Hobbes. Hobbes matters because Midgley credits (or discredits) evolutionary biologists for propounding a Hobbesian theory of human nature. Betwixt Hobbes and Dawkins (her main target of attack), however, a great gulf is fixed. Perhaps there is occasional, minor slippage in Dawkins' use of 'selfish' but he does not believe or claim in any serious, significant way that the selfish gene produces selfish human behaviour. Indeed, the needs of the selfish gene may be best served by the development of morality and co-operation among human beings; i.e. human beings who exhibit morality and co-operation are more likely to survive as a group and hence to transmit their genes. All in all this is a half-way interesting book about the limitations of interpreting human motivation in purely or predominantly 'selfish' terms. As a critique of evolutionary biology/ psychology it is, for all the author's evident sincerity, a caricature : and a gross caricature at that. Mary Midgley has done good work in moral pyschology. Unfortunately this book is no part of it.
