What Makes Us Moral?: Crossing the Boundaries of Biology

Is our motivation to be moral determined totally by our genes, or are there other factors at work? This is the only book to examine the field in its entirety, starting with Darwin and moving on to explore how morality could have evolved, and what we can learn from the discovery of so-called genes for human behaviour. In a powerful conclusion, Levy argues that while our moral motives are products of evolution, so are our immoral ones. We are only truly human when we rise above our ‘selfish genes’.
