I have said as much before and still strongly believe that error, animal magnetism, mortal mind, evil--pick the label you prefer--needs to be oppoosed and denied far more energetically and imperatively than many of us seem to. "Press on, press on, ye sons of light,/Untiring in your holy fight,/Still treading each temptation down,/And battling for a brighter crown." (Hymn #290) Christ Jesus saw clearly the need for Satan's eradication and assured his followers that each of them can utilize the talent or talents he has been given. "Behold, I give you power to tread on serpents and scorpions, and over all the power of the enemy". (Luke 10: 19) A good pair of metaphysical hobnail boots will be necessary. This isn't delicate tweezer work, like building a ship in a bottle.
Mary Baker Eddy implied that we live in "a world of sin and sensuality hastening to a greater development of power" (S&H 82: 31-32), and she wrote that over a century ago. Many of us might make greater progress if, instead of tepid, timorous, or torpid opposition to mortal mind, we followed Richard Sherman's (Tom Ewell) advice in "The Seven Year Itch" and came on like gangbusters, not, of course, with Rachmaninoff's "Second Piano Concerto", but with a greater and more vigorous understanding and demonstration of Christian Science. A failure to energetically crush out each temptation as it is encountered may leave the woolgathering treader-down with a discouragingly long--and growing longer--work order. Mrs. Eddy threw down the gauntlet emphatically to her loyal followers on a July 4 a century or so ago (Mis 176-177). How many of them (us?) are still dithering over picking it up and getting on with the challenge she was in fact requiring of them and us.
What worked so well for the Montgolfier brothers over the streets of Paris way back when will not suffice today--not that it ever really did. Satan and his progeny stoke the fires of hell with unrealized good intentions and self-satisfying pronouncements masquerading as heartfelt prayers. "Do not go gentle into that good night,/. . . Rage, rage against the dying of the light." (from "Do not go gentle into that good night" by Dylan Thomas)
Note: Ignes fatui is simply the plural of ignis fatuus, will-o'-the-wisp, something that misleads or deludes; an illusion.
