I'd already read quite a lot of research that said that people claim to be happier and healthier if they're religious. There's also a lot of new evidence now that people are more co-operative and altruistic, even if only to the in group. And, finally, the overwhelming evidence is that religious people have more children - and not in just one religion, or just one country or just one age, but all over the place.
So, I've made a shift from saying that religions are viruses of the mind to saying that religion is costly and damaging - no question! - and untruthful but it works. The cost is worth paying from the gene's point of view. So, we have a situation in which untruthful ideas are thriving, and will go on thriving, because they have all these positive effects on people. I find that extremely uncomfortable.
I wish that some Christians or Muslims or whatever would be a bit more honest and say: 'Given that the idea of God doesn't make sense' - I mean, we got here by evolution and we have no ultimate purpose - 'what else is available?' Why don't you join those of us who are atheists who would love to develop a spirituality without spirit: something that encourages us to try to understand the world in ways that are not purely materialist and self-centred but take one beyond oneself, a way of growing as human beings in empathy and compassion and openness and awareness and self-awareness which doesn't need to involve ludicrous ideas such as that God created us for a purpose. We have these spiritual yearnings, but I think religion holds us back.
Dawkins talks about the harm the fundamentalists do, but I agree with Sam Harris3 that nice, liberal religious people are as much of a problem, because they are saying that faith (which means believing in something even if there isn't any evidence for it) is a good thing. Of course, even as a scientist you've got to have faith - for example, that the basic laws of physics are not going to change tomorrow. But I think that's very different from the faith you get in religion, which says almost 'It's good to believe something without evidence.' But I think that most of my anger comes from the wickedness and cruelty promulgated by religion - particularly by Catholicism at the moment.
