- I thought this etymology was delightful, and, as with most
- things delightful, I sought it out in the dictionary. What I
- found was, to say the least, distressing (pay special
- attention to definition 4!):

- THEOREM \'the-e-rem, 'thi(-e)r-em\ n [LL theorema, fr. Gk.
- theorema, fr. theorein to look at, fr. theoros spectator, fr.
- thea act of seeing -- more at THEATER](1551) 1: a formula,
- proposition, or statement in mathematics or logic deduced or
- to be deduced from other formulas or propositions 2: an idea
- accepted or proposed as a demonstrable truth often as a part
- of a general theory : PROPOSITION <the ~ that the best defense
- is offense> 3: STENCIL 4: a painting produced esp. on velvet
- by the use of stencils for each color -- theorematic
- \the-e-re-'mat-ic, thi(-e)r-e-\ adj.

- I can only imagine endless Elvis theorems, or perhaps maybe a
- bullfighter or some buxom raven-haired beauty theorem. It's
- enough to make you not want to admit to having done anything
- like a theorem, never mind how you've achieved it (i.e., by
- proving OR showing).
-
- I'm afraid to look up LEMMA now, for fear that it'll include
- cheap art glued to a plaque of wood and lacquered heavily.
- Footprints in the sand, indeed! Or, the poker-playing dogs.
