"Wilson presses hard on the lack of any basis for morality in Hitchens' atheistic worldview. His accusation is not that Hitchens is himself overtly immoral but that Hitchens has no basis for morality. Thus Hitchens, in strenuously claiming certainty, precisely about ethical matters, is borrowing Christian concepts while denying the Christian framework which validates those concepts."
It bothers me that none of the media-savvy public intellectuals recently making the case for atheism seem to be familiar with Marc Hauser's work or the immense amount of research and interest lately into the neuroscientific basis of morality. Nevermind how offensive it is to non-Christians and indeed all nonbelievers to assert that morality owes its origin to Christian teaching, there is a burgeoning, active, exciting field of research into how elementary morality is "hard-wired" into our brains the same way language is, which is to say that it has an evolutionary basis and rationale. Robert Trivers is another researcher who has contributed hugely to the scientific examination of these phenomena. Check out Hauser's book "Moral Minds" for a mind-blowing, illuminating read.
Also thanks for your review! Very much looking forward to seeing this film.
