I don't think anyone thinks that remission is the result of some "mystical" or other-worldly occurence. Clearly there is something physically going on that we simply cannot yet explain because we don't yet have a grasp on the basic science of the condition(s). What that something(s) is has yet to be determined with any degree of certainty. Remember, we could be talking about more than one cause that could lead to a very similar set of symptoms. Certainly some treatments seem to produce undeniable benefit for some people. But until someone does a double-blind, placebo-controlled study of the treatment on the right subset of subjects and the results repeated in subsequent studies, no one can be 100% certain that the treatment in question in fact lead to the results. In the meantime, we are left to our own devices to experiment and hold on to hope. Wouldn't it be great if science caught up with all of the speculation and we finally knew which treatment would work for which people? In the meantime, we have to be open-minded to all the possibilities, including the chance that in the end we may all be wrong.
