(I am taking a break from original posts due to the holidays and because of travel after that. Until I return, here are some old posts, updated and edited, for those who might have missed them the first time around. New posts should appear starting Monday, January 14, 2008.)

In an interview, Douglas Adams, author of The Hitchhiker’s Guide to the Galaxy, who called himself a “radical atheist,” explains why he uses that term (thanks to onegoodmove):

I think I use the term radical rather loosely, just for emphasis. If you describe yourself as “Atheist,” some people will say, “Don’t you mean ‘Agnostic’?” I have to reply that I really do mean Atheist. I really do not believe that there is a god – in fact I am convinced that there is not a god (a subtle difference). I see not a shred of evidence to suggest that there is one. It’s easier to say that I am a radical Atheist, just to signal that I really mean it, have thought about it a great deal, and that it’s an opinion I hold seriously…

People will then often say “But surely it’s better to remain an Agnostic just in case?” This, to me, suggests such a level of silliness and muddle that I usually edge out of the conversation rather than get sucked into it. (If it turns out that I’ve been wrong all along, and there is in fact a god, and if it further turned out that this kind of legalistic, cross-your-fingers-behind-your-back, Clintonian hair-splitting impressed him, then I think I would chose not to worship him anyway.) . . .

And making the move from Agnosticism to Atheism takes, I think, much more commitment to intellectual effort than most people are ready to put in. (italics in original)

I think Adams is exactly right. When I tell people that I am an atheist, they also tend to suggest that surely I must really mean that I am an agnostic. (See here for an earlier discussion of the distinction between the two terms.) After all, how can I be sure that there is no god? In that purely logical sense they are right, of course. You cannot prove a negative so there is always the chance that not only that a god exists but, if you take radical clerics Pat Robertson and Jerry Falwell seriously, has a petty, spiteful, vengeful, and cruel personality.

When I say that I am atheist, I am not making that assertion based on logical or evidentiary proofs of non-existence. It is that I have been convinced that the case for no god is far stronger than the case for god. It is the same reasoning that makes me convinced that quantum mechanics is the theory to use for understanding sub-atomic phenomena or natural selection is the theory to be preferred for understanding the diversity of life. There is always the possibility that these theories are ‘wrong’ in some sense and will be superceded by other theories, but those theories will have to have convincing evidence in their favor.

If, on the other hand, I ask myself what evidence there is for the existence of a god, I come up empty. All I have are the assurances of clergy and assertions in certain books. I have no personal experience of it and there is no scientific evidence for it.

Of course, as long time readers of this blog are aware, I used to be quite religious for most of my life, even an ordained lay preacher of the Methodist Church. How could I have switched? It turns out that my experience is remarkably similar to that of Adams, who describes why he switched from Christianity to atheism.

As a teenager I was a committed Christian. It was in my background. I used to work for the school chapel in fact. Then one day when I was about eighteen I was walking down the street when I heard a street evangelist and, dutifully, stopped to listen. As I listened it began to be borne in on me that he was talking complete nonsense, and that I had better have a bit of a think about it.

I’ve put that a bit glibly. When I say I realized he was talking nonsense, what I mean is this. In the years I’d spent learning History, Physics, Latin, Math, I’d learnt (the hard way) something about standards of argument, standards of proof, standards of logic, etc. In fact we had just been learning how to spot the different types of logical fallacy, and it suddenly became apparent to me that these standards simply didn’t seem to apply in religious matters. In religious education we were asked to listen respectfully to arguments which, if they had been put forward in support of a view of, say, why the Corn Laws came to be abolished when they were, would have been laughed at as silly and childish and – in terms of logic and proof -just plain wrong. Why was this?
. . .
I was already familiar with and (I’m afraid) accepting of, the view that you couldn’t apply the logic of physics to religion, that they were dealing with different types of ‘truth’. (I now think this is baloney, but to continue…) What astonished me, however, was the realization that the arguments in favor of religious ideas were so feeble and silly next to the robust arguments of something as interpretative and opinionated as history. In fact they were embarrassingly childish. They were never subject to the kind of outright challenge which was the normal stock in trade of any other area of intellectual endeavor whatsoever. Why not? Because they wouldn’t stand up to it.
. . .
Sometime around my early thirties I stumbled upon evolutionary biology, particularly in the form of Richard Dawkins’s books The Selfish Gene and then The Blind Watchmaker and suddenly (on, I think the second reading of The Selfish Gene) it all fell into place. It was a concept of such stunning simplicity, but it gave rise, naturally, to all of the infinite and baffling complexity of life. The awe it inspired in me made the awe that people talk about in respect of religious experience seem, frankly, silly beside it. I’d take the awe of understanding over the awe of ignorance any day.

What Adams is describing is the conversion experience that I described earlier when, suddenly switching your perspective seems to make everything fall into place and make sense.

For me, like Adams, I realized that I was applying completely different standards for religious beliefs than I was for every other aspect of my life. And I could not explain why I should do so. Once I jettisoned the need for that kind of distinction, atheism just naturally emerged as the preferred explanation. Belief in a god required much more explaining away of inconvenient facts than not believing in a god.

POST SCRIPT: The Noah’s Ark horror

One of the great triumphs of Judeo-Christian propaganda is getting their followers to overlook the fact that the Biblical Noah story, which many of them believe to be true, would be the worst act of genocide ever, and committed by god to boot. Hellbound Alleee tries to correct this.
