Spinestein's definition of science is obviously a closed box. Science must never be a closed box.
Science is a closed box to the supernatural. That's part of the foundation of science and part of it's fundamental philosophy. Science seeks naturalistic explanations, not supernatural ones. Science has no business probing the supernatural or philosophical. It can't do it. Just like religious dogma has no place in science. Religion is biased and is choked full of preconceptions and superstitions.
That's why the Dover case is important. The defense seeks to CHANGE the definition and practice of science to include the possibility of supernatural intervention. At that point, it ceases being science because 'goddidit' becomes an acceptable explanation that serves to generate no new knowledge.
