 Roughly, the "Anscombe myth" arose, in part, from an actual encounter C. S. Lewis had at his Socratic Club with Catholic philosopher G. E. M. Anscombe over the soundness of the theistic argument he presents in his book "Miracles".It has been alleged that Elizabeth Anscombe, in her presentation of the perceived problematic areas in Lewis's argument, had so thoroughly discredited his argument that Lewis sank into apologetic and theological obscurity.It has also been suggested that this friendly encounter led Lewis to not only reject the Argument from Reason, but also significantly question the validity of Christianity altogether.
