Are You Saying That Science Can't Dilute Our Morals?

Christopher Hitchens, Richard Dawkins and Sam Harris have been regarded as almost evangelical fundamentalist in your humanism. How would you respond to that? I think it's ultimately very unsatisfactory because it's impossible for science not to look at everything. Steve Gould didn't seem to grasp that you could have a morality that did not depend on religion. He kind of gave religion the franchise for morality. But he missed out on the whole enlightenment thing that you can justify morality in terms of utilitarian grounds.
