If reason were all, reasonwould not exist—the willto reason accounts for it;it's not reason that choosesto live; the seed doesn't swellin its husk by reason, but lovesitself, obeys light which isits own thought and argues the leafin secret; love articulatesthe choice of life in fact; lifechooses life because it isalive; what lives didn't begin dead,nor sun's fire commence in ember.
- Wendell Berry
But towards the end, Dawkins rallied, and described how he wanted a post-religion ethics worked out without reference to tradition, authority or revelation. Uninfluenced by these things, people could get together and discuss from first principles what sort of morals were needed to ensure a good society.
This idea is of course completely impossible. It has never happened in history. It could never happen and it never will. Everyone grows up inside some tradition, under some authority and given some revelation – those are three things that every parent provides for their children, and which children will always find, even if they have to create it. When a rationalist tell his daughter not to trust authority, she believes him because he's her father and she loves him.
And if we make believe a little more, and imagine that there should ever be a community of adults all in their separate ways entirely liberated from tradition, authority and revelation, how could they possibly reason together about morality? What stories would they have in common? What language would they have?
Of course Dawkins's idea is attractive; of course we know what it means so long as we don't stop to think about it. But it is not actually true. It is an imaginary story whose truth is assumed because it seems to make morality possible. In the hard and narrow sense of myth, it is a myth just like Adam and Eve. We can play with it, and make use of it. But it is quite as "religious" as the rival stories it is meant to displace. That is inevitable. Religion is not something imposed on us by priests any more than economics is imposed on us by bankers. Both grow out of the nature of human societies.
It is an attractive idea at first glance, probably because there's usually a large, question-begging assumption accompanying it; namely, that "reason" is synonymous with our personal rationalizations. Reason is fantastic for figuring out the most effective way for you to get from point A to point B; its track record isn't quite as good when it comes to analyzing the foundation underneath points A and B or discovering why you even want to move between them to begin with.
