If science really is permanently committed to methodological naturalism – the philosophical position that restricts all explanations in science to naturalistic explanations – 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.

“Even if all the data point to an intelligent designer, such an hypothesis is excluded from science because it is not naturalistic”
