1) If God does not exist objective moral values and duties do not exist
2) Objective moral values and duties do exist
3) Therefore God exists
This is a surprisingly powerful little argument
Take point 1. Very few people can really live without belief in objective moral values. Atheists like Sam Harris, Daniel Dennett and Richard Dawkins certainly can’t. All are very stubborn moralists. So while Dawkins says that ‘there is at bottom no design no purpose no evil no good nothing but pointless indifference … we are machines for propagating DNA … it is every living object’s sole reason for being’, he still takes many moral stances. For example:
– He was mortified that Jeff Skilling of Enron took The Selfish Gene as inspiration for Social Darwinianism, justifying rampant greed and selfish behaviour
– He calls compassion and generosity ‘noble emotions’
– He judges the doctrine of Original Sin ‘morally obnoxious’
– He is morally offended by the religious indoctrination of children
– He even writes his own 10 commandments for guiding moral behaviour in The God Delusion
Such statements need objective ‘real’ moral values to underpin them and this of course stands in direct conflict with atheism for under naturalism animals are not moral agents. In other words, Craig argues, Dawkins has affirmed the first two premises of the moral argument and is, on pain or irrationality, unwillingly faced with the third.
Craig’s point: trying to construct morality without God is actually not possible.
