I fully agree that inheritance is necessary to classification. But you
implicitely take it for granted that objects are necessarily organized
into classes.
I argue that you can create good objects, as abstractions of objects of
the real world, with proper encapsulation, without classification.
Classification is a way of organizing objects, but not the only one.
