Dawkins on Intelligent Design

I have no beef with Intelligent Design one way or the other, although Edward Feser has gone a long way to convincing me it is more harmful than helpful. But Richard Dawkins sure doesn't make it easy to write off the ID folks.

In his book The God Delusion, Dawkins discusses creationism in his chapter "Why There Almost Certainly is No God." Arguing against the ID notion of "irreducible complexity", he casts it as a fallacy in the form of The Argument from Personal Incredulity: If I can't imagine how something came about, then it couldn't have come about naturally and must have been the creation of special design. Dawkins says there are many examples where this isn't true, and cites a reference in support of his argument:
In his book Seven Clues to the Origin of Life, the Scottish chemist A.G. Cairns-Smith makes an additional point, using the analogy of an arch. A free-standing arch of rough-hewn stones and no mortar can be a stable structure, but it is irreducibly complex: it collapses if any one stone is removed. How, then, was it built in the first place? One way is to pile a solid heap of stones, then carefully remove stones one by one. More generally, there are many structures that are irreducible in the sense that they cannot survive the subtraction of any part, but which were build with the aid of scaffolding that was subsequently subtracted and is no longer visible.  Once the structure is completed, the scaffolding can be removed safely and the structure remains standing. In evolution, too, the organ or structure you are looking at may have had scaffolding in an ancestor which has since been removed.
Does Dawkins realize he just gave a powerful argument for intelligent design? Yes, arches are typically built by piling stones supported by a structure, then removing the structure. This is how the Romans - intelligent agents - did it. Dawkins carefully abstracts from the agent ("one way is to pile a solid heap of stones...") as though describing an intelligent process without the agent somehow magically removes the agent. This isn't the first time I've seen this kind of thing happen (citing an example of intelligent design in support of an evolutionary process); I wonder if Dawkins knows what he is doing or is simply blind to it.

I really enjoy posts like this one since it shows the blind spots of so many contmeporary thinkers. I read this article this morning:

http://online.wsj.com/article/SB10001424052702304388004577531270272951132.html?mod=WSJ_article_comments#articleTabs%3Darticle


In the last paragraph the writer concludes:

"The origin of our tendency to confirmation bias is fairly obvious. Our brains were not built to find the truth but to make pragmatic judgments, check them cheaply and win arguments, whether we are in the right or in the wrong."

I want to ask the writer how can he possibly know this Truth based on his views that our brains are not wired for the truth?

My belief is that many of our contemporary thinkers in the media(newspapers, popular blogs, media) really don't care for the Truth and are more interested in selling books and being considered "smart" and/or "cutting edge". This is no different then Greece circa 500 BC.

That's right... and the mention of ancient Greece is appropriate. Socrates gave the one and only way to deal with the possibility of our cognitive fallability, and that is through dialectics. There is no silver bullet to keep yourself from error, only the subjective commitment to explore your own thinking (and to subject it to scrutiny through dialectic) to root out the things you think you know, but don't.

Amen. Keep up the good work.

I doubt whether Dawkins and his like have much interest in truth. The problem religion poses for them is that it leads us to question the activities of those who seek to act like God.
