Not true -- unless you consider data encapsulation and multiple objects
of the same abstract type as "minor" (I certainly don't).  Ada and
Modula provide the former, but few languages provide the latter.  In
any event, these are orthogonal to (and as important as) inheritance.

For the record: Peter Wegner presented a paper at OOPSLA 87 which gave
a taxonomy of various forms of "objectness".  Worth a read, as it
does try to provide consistent terminology.  May be quickly dated, however,
given the current interest in OOP, OOD, OODBMS, and all the other OO
thingys around.
