C.S. "Lewis is certainly right to suppose that in considering the question of whether miracles exist there is a danger that one will appear to a priori arguments and assumptions. But the solution to this problem is not to decide on naturalism or supernaturalism beforehand. Rather, one must attempt to reject the a priori arguments and instead base one's position on inductive considerations. Lewis has not shown that this is impossible. Thus he has not shown that one must choose between naturalism and supernaturalism before investigating the possibility of miracles."
