The fact that there are attractions and repulsions lead us to postulate that
there are two kinds of charge.  Why they attract and repel is no more known
than why two objects attract each other gravitationally.  They just do and
gravity is the name we give this phenomenon.  Electricity is the name we give
to the phenomenon related to forces by charges.  We don't know what it IS, but
we know pretty well what it DOES.
