Naturalism versus Supernaturalism
Naturalism has the priority over supernaturalism, not because it is the more economical of two explanations, but because it is the only framework in which explanation is possible.... [T]he contest between naturalism and supernaturalism is not a battle between two rival modes of explanation, in which naturalism is selected because it is a better or more economical mode of explanation. Rather, naturalism is selected because it is the only possible method of explanation. Naturalism is the only context in which the concept of explanation has meaning. Once the theist removes himself from the framework of natural causality and the general principles or "laws" by which man comprehends the universe, he forfeits his epistemological right to the concept of explanation and precludes the possibility of explaining anything. --George H. Smith, Atheism: The Case Against God , 1974
