Richard Dawkins – The Selfish Gene (30th Anniv. Ed., 2006)
One of the dominant messages of The Selfish Gene (reinforced by the title essay of A Devil’s Chaplain) is that we should not derive our values from Darwinism, unless it is with a negative sign. Our brains have evolved to the point where we are capable of rebelling against our selfish genes. The fact that we can do so is made obvious by our use of contraceptives. The same principle can and should work on a wider scale.
