This is getting deep. It is an embarrassing metamathematical fact that
numbers cannot be defined. At least, mathematicians gave up trying a
century ago.

   In mathematics, the essence of counting a set and finding a result n,
   is that it establishes a one to one correspondence (or bijection) of
   the set with the set of numbers {1, 2, ..., n}.

Our ancestors defined the fingers (or digits) as "the set of numbers."
Modern mathematicians have managed to enhance the definition
quantitatively but not qualitatively.
