This is Augustine Shutte's defense of the argument from reason

This requires JSTOR to open. The author, at the time he wrote this, was unaware that Lewis has revised his argument. It references another defense of Lewis against Anscombe by Eric Mascall in Christian Theology and Natural Science (Longmans, 1957), which appeared 3 years before Lewis's revision was published.

I think the Mascall-Shutte reformulation is open to the objections to Skeptical Threat arguments. But it is interesting.
