If science were capable of testing methodological naturalism to see whether it is in accord with objective reality then we might know whether this viewpoint will yield knowledge in accord with the same. Regardless, methodological naturalism is capable of recognizing intelligent design. It may have difficulty ascertaining the disposition or personal nature of an intelligent designer, but it has little difficulty in ascertaining the presence of organized matter performing specific functions - a hallmark of intelligent design.
"If science were capable of testing methodological naturalism to see whether it is in accord with objective reality then we might know whether this viewpoint will yield knowledge in accord with the same."
It can't be tested since it is a practical philosophical contention science has taken to ensure objectivity.
"Regardless, methodological naturalism is capable of recognizing intelligent design. It may have difficulty ascertaining the disposition or personal nature of an intelligent designer, but it has little difficulty in ascertaining the presence of organized matter performing specific functions - a hallmark of intelligent design."
Actually, it can't. If the proposed Designer is a priori proposed to be supernatural, then by definition, it contradicts methodological naturalism.
