Back on topic, I think that (especially in Scotland), more should be made of David Hume as one of the most important philosophers of the Enlightenment. I am in no way an expert, but the little that I have heard and read makes me think that we should have better knowledge of his work and thinkings. For example this extract in Wikipedia:
The design argument
One of the oldest and most popular arguments for the existence of God is the design argument – that all the order and 'purpose' in the world bespeaks a divine origin. A modern manifestation of this belief is creationism. Hume gave the classic criticism of the design argument in Dialogues concerning Natural Religion and An Enquiry concerning Human Understanding. Here are some of his points:
For the design argument to be feasible, it must be true that order and purpose are observed only when they result from design. But order is observed regularly, resulting from presumably mindless processes like snowflake or crystal generation. Design accounts for only a tiny part of our experience with order and "purpose".
Furthermore, the design argument is based on an incomplete analogy: because of our experience with objects, we can recognise human-designed ones, comparing for example a pile of stones and a brick wall. But in order to point to a designed Universe, we would need to have an experience of a range of different universes. As we only experience one, the analogy cannot be applied. We must ask therefore if it is right to why we ought to compare the world to a machine — as in Paley's watchmaker argument — when perhaps it would be better described as a giant inert animal.
Even if the design argument is completely successful, it could not (in and of itself) establish a robust theism; one could easily reach the conclusion that the universe's configuration is the result of some morally ambiguous, possibly unintelligent agent or agents whose method bears only a remote similarity to human design. In this way it could be asked if the designer was God, or further still, who designed the designer?
If a well-ordered natural world requires a special designer, then God's mind (being so well-ordered) also requires a special designer. And then this designer would likewise need a designer, and so on ad infinitum. We could respond by resting content with an inexplicably self-ordered divine mind but then why not rest content with an inexplicably self-ordered natural world?
Often, what appears to be purpose, where it looks like object X has feature F in order to secure some outcome O, is better explained by a filtering process: that is, object X wouldn't be around did it not possess feature F, and outcome O is only interesting to us as a human projection of goals onto nature. This mechanical explanation of teleology anticipated natural selection. (see also Anthropic principle)
The design argument does not explain pain, suffering, and natural disasters.
Now - where have I read this kind of thing recently Mr Dawkins?
