Perfect! May it be a vague, wandering walk, so you can enjoy the
   scenery smile emoticon

   x (algebra) is metaphorical. People often don't realize, in this
   days of the Glorification of all things Mathematics,that numbers
   themselves are metaphors - stand-ins for another concept. Yet we
   treat them as-if they have substance of their own, but they
   don't, except as a system when in use. But I must express my
   bias here. I made a book that nobody will buy because it's a
   mess. While everybody is looking to improve the specificity of
   things, I look to see what things have in common; INTENTIONALLY
   exposing their vagueness and metaphorical value.

   Over a weekend once a few years ago, I took the largest
   available English thesaurus used by linguists and such, and
   cross-referenced all of it to itself, to see what happened. I
   found a pattern. What is the meaning of this pattern? I don't
   know, except that in SOME WAY, each of the words in the 5 ...
   categories I guess that emerged, have _something_ in common with
   each other.
