"polarized" terminology

    I'll have to think about the semantics of this one.  I was thinking that
there is a difference between polarizing characters and polarizing
"character states" (which is a special case of "ordering" character states).
     What term would one apply to polarizing (dividing) a character into
just two character states?  Whatever you call that kind of polarization, it
needs to be done before one can perform a cladistic polarization (i.e., in
the strict sense) of the "character states" (i.e. "ordering" sensu lato).
Is Curtis referring to polarizing his characters, or is he just ordering the
character states?
     Don't mean to nitpick, but I've never really pondered the details of
this terminology.  I'll really have to give this some more thought.
