Of course, I was thinking about the same names except Joyner who I still don't know.

But terrible at systems architecture and information management.

And he still lives in the file procesing age (the stone age).

But let's see how Kim Bruce defines some of the OO terms in "Foundations of Oject-Oriented Languages".

Object:

Objects encapsulate both state and behavior. In particular they consist of a collection of instance variables, representing the state of the object, and a collection of methods, representing the behavior that the object is capable of performing. The methods are routines that are capable of accessing and manipulating the values of the instance variables of the object...
As is the case in Java and Smalltalk, we wil assume that all objects are implicit references...

Class:

Classes are extensible templates for creating objects, providing initial values for instance variables and the bodies for methods. All objects generated from the same class share the same methods, but contain separate copies of the instance variables. New objects can be created from a class by applying the new operator to the name of the class.

I have not found any definition for instance variable, and the sloppiness and contradictions are evident.
