A while back I mentioned that I no longer support the intelligent design theory (ID). Most of my reasons are simply philosophical (though there are scientific errors within the theory, scientific errors can always be fixed whereas philosophical errors can sometimes require the ejection of an entire system of thinking). One of the biggest ones, however, is that ID is unwittingly problematic when it comes to the problem of evil.
Contrary to most straw-men arguments, ID theorists accept many premises within evolution, but simply deny that natural selection works as an explanation for everything. They believe that across time God has intervened in order to direct evolution or to create irreducibly complex organisms. But by stating that God has directly interjected within creation along the process of evolution means that God has done some pretty nasty things. It would mean that God, not natural selection (which can be attributed to the Fall, even prior to humans) caused multiple natural evils. Even once humans were sentient and in His image, it would mean that He, not natural selection, caused death and suffering in order to help the species evolve as a whole.
Overall, if God interjected along the evolutionary track then He necessarily had to cause evil and take part in evil. Furthermore, it would mean that God’s creation wasn’t up to His standards when it was originally created. Now, one who believes that God sustains creation could easily argue that God allowed creation to exist in a fallen state in preparation of the Fall, but that His standard remained perfect. In fact, this is what William Dembski essentially argues in the previously linked book. But a problem exists when God acts in order to cause an evil rather than simply allowing the evil to occur. Hence, ID poses a serious problem when it comes to the problem of evil. Along with many other reasons, I can no longer consider it a tenable theory for Christians (or theists) to rely upon.
