All very interesting I'm sure.

However

I've been thinking about Arveds question

"I don't know what more you think object-oriented is, at the basic level"

One of the key ideas behind OO is the concept of information hiding. We 
hide the state of an Object and restrict the available interactions on 
that state by publishing a contract. Simply put, the contract is the set 
of methods that clients can call. I see this as absolutely fundamental 
to the idea of an Object. My C code did not exhibit this property, 
anyone can directly manipulate the state (the pointer to pointer to 
struct node) bypassing the published interface of push() pop() and 
top(). My example does however meet the following criteria

"... to collect behaviors into types with attributes, and operate on 
objects of those types.

To write OO code I need an OO language. Of course that's not to say that 
just because you use an OO language your code is OO and that you can't 
approximate OO in a non OO language ... of course ultimately you may 
argue that everything that can be done can be done in assembler, well 
OK, you write your next business system in assembler, I'll use Java. 
Would you like to bet who would finish first

If I want to write a heap manager I'll use AT&T GAS, if I want to write 
a device driver I'll use C, if I want to write OO I'll use Java.

The bottom line is that an Object Oriented language like Java provides 
me with the tools to write code that exhibits the three main properties 
desirable of Object Oriented Software

Encapsulation (supported by information hiding), inheritance and 
polymorphism.

Anything that doesn't exhibit these properties isn't OO IMHO

That is why I believe that the statement

"Object oriented means to collect behaviors into types with attributes, 
and operate on objects of those types"

doesn't even begin to cover what "Object oriented means"

Incidentally, Philosophically I believe that OO is a state of mind, but 
that's another story.
