Michael Shermer on Placeholders for Mysteries"Science and Religion: Incompatible?" at The Blog at Huffington Post (March 7, 2012).
Science operates in the natural, not the supernatural. In fact, I go so far as to state that there is no such thing as the supernatural or the paranormal. There is just the natural, the normal, and mysteries we have yet to explain by natural causes. Invoking such words as “supernatural” and “paranormal” just provides a linguistic place-holder until we find natural and normal causes, or we do not find them and discontinue the search out of lack of interest. ¶ This is what normally happens in science. Mysteries once thought to be supernatural or paranormal happenings — such as astronomical or meteorological events — are incorporated into science once their causes are understood. For example, when cosmologists reference “dark energy” and “dark matter” in reference to the so-called “missing mass” needed to explain the structure and motion of galaxies and galaxy clusters along with the expansion of the universe, they do not intend these descriptors to be causal explanations. Dark energy and dark matter are merely cognitive conveniences until the actual sources of the energy and matter are discovered. When religious believers invoke miracles and acts of creation ex nihilo, that is the end of the search for them, whereas for scientists the identification of such mysteries is only the beginning. Science picks up where theology leaves off.
