I guess can see how it would work. For all his vaunted empiricism (despite being really bad at empiricism, but whatever), Dawkins mostly seems interested in recreating the Cartesian God at a material level, in the sense of constructing capital-S Science as an epistemological guarantor for that which he's already convinced himself that he knows, and what he knows is an unreconstructed bourgeois liberalism.
Is that anything close to what you were getting at? (I get the feeling that I'm missing something- I'm afraid what I've read of/on Nietzsche has mostly been about his critiques of reason, conciousness, morality, etc.; basically the proto-existentialist stuff. Not really read much on the ubermensch/last man stuff.)
Well, I guess to explain my reasoning, I should explain my take on the God is Dead bit.
So, I understand that not to be a declarative statement by Nietzsche, but a recognition of an existant fact: That Christianity no longer inspires confidence as a worldview in the west, despite the large number of people who cling to it out of tradition. No one anywhere would be motivated to do something because god wills it.
However, in keeping with the article you linked to. Nietzsche recognized that destroying the philosophical and intellectual basis of the west was a big fracking deal. While he certainly was
glad that Christianity was going away, he recognized that nobody was working on anything really to replace it. Hence his need to create a morality system independent of God, or any other absolute arbiter.
He warned that if we didn't do this, we'd fall into Nihilism. The death of god leads to a loss of universal perspective, and reason for anything. Dawkins seems to be the exact thing he's talking about.
He talks about materialism, but isn't very good at it, and doesn't seem to have any profound faith in it. He muddles about with some idealism, and vaguely looks to some capital-S-science to guarantee what he knows, which as you say, is unreformed bourgeois liberalism, complete with unconscious inclusions of the Christian morality Nietzsche disliked so much. He putters along with no meaningful worldview. He is a social commentator with no real social goal. He simply accepts his Bourgeois Liberal world because he lacks the courage to believe in anything else.
