It’s rather like, if you think back in terms of animal evolution, an animal that’s grown an incredible carapace around it, such as a tortoise—that’s a great survival strategy because nothing can get through it; or maybe like a poisonous fish that nothing will come close to, which therefore thrives by keeping away any challenges to what it is. In the case of an idea, if we think, “Here is an idea that is protected by holiness or sanctity,” what does it mean? Why should it be that it’s perfectly legitimate to support the Labour Party or the Conservative Party, Republicans or Democrats, this model of economics versus that, Macintosh instead of Windows, but to have an opinion about how the universe began, about who created the universe, no, that’s holy? What does that mean? Why do we ring-fence that for any other reason other than that we’ve just got used to doing so? There’s no other reason at all, it’s just one of those things that crept into being, and once that loop gets going, it’s very, very powerful. So we are used to not challenging religious ideas, but it’s very interesting how much of a furor Richard creates when he does it! Everybody gets absolutely frantic about it because you’re not allowed to say these things. Yet when you look at it rationally, there is no reason why those ideas shouldn’t be as open to debate as any other, except that we have agreed somehow between us that they shouldn’t be.
