Here are some very eloquent and controversial explanations and observations from Francis Collins. A number are directed against dogmatic atheists and dogmatic GENESIS literalists alike. He shows that you can be an orthodox Christian and know that evolution happened; "theistic evolution" in the loose (non-Hegelian, no implication of "intelligent design") sense he uses the phrase is not an oxymoron. He also shows that you can’t use what we really know about evolution to prove that God is dead. Unfortunately, he’s not quite a Thomist (his book shows his main theological influence to be C.S. Lewis), and few (on either side) are going to agree with his nuanced if finally incorrect view on embryos and research. He only hints at his scientific reason for opposing abortion. Collins is pretty much the most impressive scientist ever to testify bfore the Bioethics Council. He’s amazingly lucid, confident, and appropriately modest about what we can know and likely accomplish (a lot, but far from everything) through scientific research.
