One of the sidebar debates in the intelligent design controversy is the clash between IDers and theistic evolutionists. Both agree that the world is intentionally designed but IDers believe that the evidence of this design can be detected in the world whereas TEers don't. TEers argue that natural forces and laws have produced the world as we see it (at least the living world) but that these laws and forces were the product of a Divine mind. Thus, TEers maintain, even though God is the primary cause of the world, we can know this only by faith not by any discovery of science.
According to TE the world appears just as it would were natural forces and laws solely responsible for it. IDers argue that, on the contrary, the world shows immense evidence of an underlying intelligence. The intelligence may not be that of the God of the Bible (though most IDers personally believe it is), but it's an intelligence all the same.
It seems like a small difference to be so exercised over but the theistic evolutionists, at least, are adamant, and sometimes even angry, in their opposition to ID, especially their opposition to treating ID as science.
A good introduction to the difference between the two positions is a debate that took place about a year ago between William Lane Craig and Francisco Ayala who addressed the question: Is Intelligent Design Viable? Craig argued for the affirmative and, as usual, pretty much dominated the event, which is interesting because Craig is a philosopher (not even a philosopher of science) and Ayala is a biologist.
Anyway, if you'd like to hear the audio you can listen to it here. There's also video of Craig's opening presentation here. The comments at the first site are also worth checking.
