In response to the claim that ID is just creationism (a slippery enough term as it is that can range from mere theism all the way to those who think Genesis 1 is a science textbook), I've been saying that ID is perfectly consistent with a closed universe of evolution, as long as the natural causes involved are not merely natural causes but are purposive, intelligent causes, and as long as those causes are detectable as intelligent causes. Most theistic evolutionists do not say that and therefore do not accept ID arguments. But someone who does should be welcome under the ID umbrella.
I looked at William Dembski's statements on this in my last post on the subject. I now turn to Phillip Johnson. Since this interview is one common place anti-ID folk have pointed to in order to argue that Johnson holds the opposite view, I've decided to use that as my source. Here is the first major quote relevant to this issue:
Theistic evolution is the same thing as atheistic evolution with a certain amount of God-talk. They don’t see any merit whatsoever in alleging that God left us some fingerprints on the evidence.
I think what's often going on is that ID opponents see him distancing himself from theistic evolution, and they then wrongly conclude that he's ruling out the sort of view with theistic evolution and signs of intelligent design together. But look closely about what he says about theistic evolution. He's not complaining about the view that everything was designed in such a way that evolution would happen but would reveal the signs of intelligent design. He's talking about the view that everything happened the way atheistic evolutionists say it did, i.e. God's fingerprints aren't on creation in order to have something to base an ID argument on. So he's not disagreeing with theistic evolution per se. He's disagreeing with theistic evolution as it's normally held. The usual theistic evolutionist does have a view that contradicts ID. The theistic evolutionist who insists that God left fingerprints that we can detect and then use as a basis for an ID argument is, of course, not inconsistent with ID, because it's the presence of those footprints that's all that the ID argument insists on.
