If science really is permanently committed to methodological naturalism, it follows that the aim of science is not generating true theories. Instead, the aim of science would be something like: generating the best theories that can be formulated subject to the restriction that the theories are naturalistic. More and more evidence could come in suggesting that a supernatural being exists, but scientific theories wouldn’t be allowed to acknowledge that possibility. Imagine what might happen in my pulsar message scenario – long after overwhelming evidence has convinced everyone that supernatural causation is occurring, scientists would still be searching for naturalistic causes. The scientists themselves may agree that the causes are supernatural, but, because they are subject to the constraint of methodological naturalism, they are not allowed to postulate such causes while doing science. Science would rightfully be marginalized – what is the point of spending all these resources investigating naturalistic causes, long after it is evident that the causes are supernatural? I’m not saying that society would want to completely stop investigating the possibility of natural causes, but by failing to countenance the possibility of supernatural hypotheses in the pulsar scenario, scientists would be missing out on a potential revolution in our understanding of the world.
