In a pure object-oriented design a base class is *more abstract*
(conceptually) than the class derived from it (which is conceptually
more concrete). I suppose it depends on what you mean by it being
"the abstraction".

The abstraction here is synonymous with the abstraction defined in
OOPS concepts?
