Other people will ask how I can possibly claim to know. Isn't belief-that-there-is-not-a-god as irrational, arrogant, etc., as belief-that-there-is-a-god? To which I say no for several reasons. First of all I do not believe-that-there-is-not-a-god. I don't see what belief has got to do with it. I believe or don't believe my four-year-old daughter when she tells me that she didn't make that mess on the floor. I believe in justice and fair play (though I don't know exactly how we achieve them, other than by continually trying against all possible odds of success). I also believe that England should enter the European Monetary Union. I am not remotely enough of an economist to argue the issue vigorously with someone who is, but what little I do know, reinforced with a hefty dollop of gut feeling, strongly suggests to me that it's the right course. I could very easily turn out to be wrong, and I know that. These seem to me to be legitimate uses for the word believe. As a carapace for the protection of irrational notions from legitimate questions, however, I think that the word has a lot of mischief to answer for. So, I do not believe-that-there-is-no-god.
