CS Lewis Critique of Naturalism/Physicalism/Materialism and Determinism
“No account of the universe can be true unless that account leaves it possible for our thinking to be a real insight. A theory which explained everything else in the whole universe but which made it impossible to believe that our thinking was valid, would be utterly out of court. For that theory would itself have been reached by thinking, and if thinking is not valid, the theory would, of course, be itself demolished.”
Miracles, p. 26
