I am with you on b), but I hesitate to agree on a). It depends on what you mean by “removing theism from science”. Some great scientists like Newton used to believe in a version of God-of-the-gaps, which was later proven false by Laplace. Incidents like these suggest that it is not good for theism if we based its arguments on current gaps in our scientific knowledge. I think the gradual adaptation of strict methodological naturalism is a natural outcome of what scientists have discovered to work best.
To take a more personal example: I am working on an experiment that tries to find a reason for why there is more matter than antimatter in the universe. I could simply give up like Newton and say that God created the universe to have initial conditions of having more matter, and by His providence, prevented the washing out of the asymmetry throughout the evolution of the universe. But then I would no longer have motivation to do a PhD…
Yes, I see the same thing happening in an FB group about theistic evolution that I participate in sometimes. The pendulum has swung too much to the other side, in too easily dismissing the theology in favor of science. The dismissal of the scientific viability of a de novo A&E that @swamidass likes to bring up is a great example of this.
I think dismissing it out of hand just because it came from a philosopher is uncalled for. But you have to understand why scientists can be easily offended if someone else tries to define their discipline for them. This is like a Western anthropologist defining Balinese culture and a Balinese person finding that definition to be utterly alien from his own experience. Perhaps the anthropologist, being an outsider, is able to point out some things which are missed. But I think the Balinese man has a right to be given the chance to define it himself.
By “theology or philosophy”, do you mean something like a Thomistic account of divine action? (I noticed some posts related to Thomism on your blog.)
