I've been musing about this interesting 'theory' just lately. Essentially it claims that there are some things about life (in the biological sense) that are just too complicated to have evolved by natural selection, and so instead they must have been designed by some more powerful agent.

It's been claimed that this is just creationism in pseudo-respectable guise, and certainly it's seems to have been treated that way in the Kansas State Board of Education. But I guess we can do the proponents the politeness of taking at face value their claim that the Christian God is not a necessary component.

My interest is in the actual structure of the argument. It's actually very old (Thomas Aquinas I believe put it forward) and so presumably has a lasting appeal, but it seems to me to be impossibly weak. The weakness is that it seems to take the arguer's own paowers of imagination / reasoning as axiomatic of the system. It's saying "I can't imagine how this could have arisen by non-designed means, therefore it can't have." You would think it could automatically be refuted by someone else saying "Well, I can quite easily imagine it, so boo sucks to you." Although a philosopher would probably put that more elegantly.

In the 19th century opponents of Darwinism cited the eye as an example -- saying that part of an eye provided no benefit, therefore natural selection could not have evolved it gradually towards its current form as Darwinists suggested. This was quite easily shot down by showing that just by looking around the animal kingdom of today we can identify a whole spectrum of optical structures which are less complex than our own eyes but which provide benefit to their users.

Today's intelligent design advocates use things like the bombardier beetle, the blood clotting sequence, and the bacterial flagellum as examples of things which only work at all when fully realized. I don't know enough biology to be able to counter these examples, but presumably it can be done?

The more practical question though is about whether ID should be taught in schools. Richard Dawkins has said that this would be equivalent to teaching flat earth theory, and of course Flying Spaghetti Monsterism also has its advocates. However it seems to me that it would be useful if schools gave a bit of perspective on how science arose and the intellectual battles it had to fight, rather than just handing it down on stone tablets. The Victorians were presented with Darwinism as an alternative to the prevailing creationist theory, and they were intelligent enough to (mostly) see that Darwinism was more likely to be right. Won't our children understand natural selection better if they work out for themselves why it's superior to what came before, rather than just being told that it's right because the syllabus says so?

There was a very fine New scientist all about ID recently....

1) US poll - if I can remember the figures right
55% Americans believe God intervened in their evolution
30% believed humans were created directly
15% believed Man evolved without intervention(whether a creator started the world/universe or not).

I find these figures scary.

2) ID proponents use the term "theory" in its layman sense to give equal weight to the scientifically-termed theory of evolution - as in a testable, evidence based system of reasoning to explain how things are.

3) ID proponents are willing to concede evolution on the small short-term scale (eg drug resistance, colour of moths,...) but the big scale which isn't observable is somehow intrinsically different.... and fossils conveniently don't show enough detail to prove every single point of change

4) ID requires a director, who, when they let their guard down is invariably the Christian God.


I am a confirmed agnostic. Should it ever be proved to me that there is a creator, I will be much more impressed by one that just set the universe going, and we emerged from it, than either total determinism or "god the meddler".....

If ID is to be taught, it should be taught only as part of religious education as a belief framework. Pretending it has equal weight to science and logic damages education.

I'm not suggesting that it should be taught, but that it should be taught about -- and I think (in the absence of epistemology lessons...) science lessons are the appropriate context for that, because as those statistics show, ID is an increasingly important part of the socio-cultural background in which science is practised.

The biggest problem with ID is that it IS taught, as a statement of fact, and taught to have as much validity as evolution. Provided your belief system doesn't mean you stone schoolchildren, confine people in concentration camps, summarily torture and execute them or blow us up, then your belief should be pretty much up to you. If held honestly, I may even respect you for it, despite my disagreeement (and a slight feeling that you may be self-deluded).

School is different. People should be taught to think (contrary to much religion), to question, and not to trust or follow charletans, bigots and liars. ID says "for the big questions, take it on faith, and my say-so. It's too difficult to think of something different". No.
