Spelling checkers are not useful unless you already know how to spell. But rather than lecture, we provide an example. The following passage passed the spelling checkers in two word-processing programs.
In a weigh, science might be descried as paranoid thinning applied too mature: we are cooking four nocturnal conspiracies, fore collections among apparently desperate data. Hour objection is two obstruct from Nature (rite-hemisphere thinning), but many proposed pat-turns do knot in fact correspond to the date. Thus awl proposed pat-turns must be subjected two the sleeve off critical analyst (loft-hemisphere thinning). The search fore pat-turns without critical analysis, and ridged skepticism without a search four pat-turns, ore the antidotes of incomplete seance. The affective pursuit of knowledge requires both funk-shuns.
Calculus, Newtonian physicals and geometrical up-ticks was awl derived by fundamentally diametrical argue-mints and are today taut an demonstrated largely bye analytical argue-mints: creating mathematics and physics is more of a rite-hemisphere funk-shun then reaching it. . . . The creation act has mayor rite-hemisphere components. Butt argue-mints on the avidity of the result ere largely left-atmosphere funk-shuns.
This passage is a corrupted version of the fine writing by Carl Sagan in The Dragons of Eden, Random House, New York, 1977, p. 183.
