Arrington claims that there are only three positions in this debate.
In summary, there are three positions in play here.This isn't correct. I support the 4th position; namely ....
(1) The traditional theist observes the overwhelming appearance of design in living things and is content to conclude that things are they way they appear to be, i.e., that living things appear to be designed for a purpose because they are in fact designed for a purpose.
(2) The atheist admits that the appearance of design in living things is overwhelming but asserts that the appearance of design is an illusion and in reality natural law and random chance combine to produce a result that only appears to be designed.
(3) The Barr-type theistic evolutionist admits that the appearance of design in living things is overwhelming but asserts — like the atheist — that the appearance of design is an illusion and in reality natural law and random chance combine to produce a result that only appears to be designed. The TE then goes one step further by asserting that the explanation of the illusion of design is itself an illusion, because the randomness of evolution is in fact directed.
(4) When you step back and look at the big picture, living things do not appear to be designed and they do not appear to have a purpose. While there may be some features of living things that have been honed by natural selection, they are the exception, not the rule. Even those features with a strong illusion of design look much less designed when you examine them closely.
When I talk about Evolution by Accident I intend that to be an attack on Intelligent Design and also an attack on the Dawkins' view of evolution.
