Incidentally, as Mr Molluscan keeps asking me why I think I'm better than Popper, Newton and Einstein, perhaps I should ask him now whether he thinks he's better than Professor Dawkins, who, er, knows a fair bit more about evolutionary biology than yer average man-in-the-street, to slightly understate the case. Yeah, yeah, appeal to authority an' all that, but what's a chap to do? Anyway, I won't ask him, so it don't count!
