Here I am once again a touch chastened. There may have been some ready, fire, aim in my assertion in the previous entry that we need to relentlessly ferret out error in out thinking. Well, of course we need to find error and get rid of it, but an excellent Journal article by L. Ivimy Gwalter, "What It Means To Be A Christian Scientist" (June 1970), makes some useful and perhaps corrective (for me) and refining points. The article focuses in part on the need for watching and shows that Mrs. Eddy very often couples prayer with watching as one way to meet and overcome error, false belief. One needs to go no farther than page one, paragraph one, of Science and Health for a QED of Mrs. Gwalter's observation.
On the other hand, no where that I can recall does Mrs. Eddy admonish us to unite as a band of Chestnut Hill Irregulars, don our Holmesian deerstalkers, and set out (mentally, of course) to find a demon's spoor and drive a wooden stake in its evil heart when it is located (to mash together a couple of metaphors). As Pogo famously stated: "We has met the enemy, and it is us." If we watch our thinking faithfully, aggressive mental suggestion will show up soon enough (by definition), like the Blob. There are doubtless days for many of us when we may be up to our necks in mortal mind's malignant and nefarious blob of suggestions. Mrs. Eddy wastes no time in Science and Health telling us what we can do to take these serpents by the tail, snake by snake, and start our own collection of sturdy staffs upon which we can lean in the future.
