@Eorl,
Quote:If a god (this author seems to have a specific one in min) exists in some form scattered evenly throughout the universe, then it's existence must be detectable in some form, like the background radiation "wrinkles in time". For example, if people pray for a good outcome, then the effects can be tested and measured. If said god influences animals and matter then that too is testable.
But, with all due respect, this is the whole problem in this dialog. 'God' - and I use the square quotes intentionally - is not anything. There is no such thing, search high or low. This is the meaning of 'transcendent'. It means 'beyond'. What is a transcendent being beyond? Beyond existence, beyond the universe, and naturally beyond anything we can detect, imagine or test for.
Here's an analogy. Say I get a report from some villagers on an island in Java, some new mammal. I find some spores, some footprints. How do I get a specimen? Set up an infra-red camera in the forest and wait patiently. Sooner or later if I am lucky I will get photographic evidence.
Now 'spiritual beings' are not like that. How, traditionally, have spiritual beings been sought out? The answer is, through meditation, austerity, mental purification, and so on. That is what monks spend their lives doing. And they report (and have reported, since about the beginnning of written history) that through these practices, through mental purification and concentration, that transcendent dimensions of being are disclosed.
In fact, philosophically speaking, and leaving aside that it may be culturally taboo in an industrial/scientific society, what is wrong with the idea that there are particular forms of knowledge that are only available in the first person, to a suitably prepared mind?
Now I am not asking you to believe this, or believe anything. But there is abundant literature from all over the world, and all throughout history, provided by anthropological and cultural historians, of this kind of understanding.
But it needs to be clear that Dawkins has no idea of this kind of 'first person knowledge of transcendent states'. Nor, I would suggest, will he ever have any idea, because of his starting point. Having formed a complete misconception of the subject matter of religion, I predict he will spend the rest of his life loudly barking up the wrong tree.
And aside from everything else, the nature of the material universe, it may be recalled, is once again a very mysterious question. At time of writing, we can't account for 95% of its mass, so I would not be overconfident about what science can or can't detect.
