I meant the ones that I quoted in the article I was responding to
(maxtal = John MAX Skaller):

To me, an abstract class is a class without any actual objects of that class,
so the idea of an "abstract object" seems to be an oxymoron. Similarly, the
idea that an object can have "state" that is not stored in its "storage" seems
to make a mockery of the whole idea of "storage".

I can understand the opposing view, but it seems to me that we are just
starting from different axioms. Anyhow, this discussion does not seem to be
very fruitful.
