That is pretty much the end of materialism, empiricism and positivism as valid theories...
Materialism and empiricism (2 cornerstones of neodarwinism) have been refuted many times over. Here is a refutation from C.S. Lewis:
"...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 eplained evertything else in the whole universe but which made it impossible to believe that our thinking was valid wold be utterly out of court. For that theory wold itself have been reached by thinking, and if thinking is not valid, that theory would, of course, be itself demolished. It would have proved that no argument was sound..."
"...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 univere but which made it impossible to believe that our thinging was valid would be utterly out of court. For that theory would itself have been reached by thinking, and if thinking is not valid, that theory would, of course, be itself demolished. It would have proved that no argument was sound -- a proof that there are no such things as proofs -- which is nonsense."
