Why did the originators of object orientation rename "structures" to
"objects"
and "procedures" to "methods"? Hubris and arrogance, in my opinion.

This simply says that the writer has not really understood the essential
differences. I read the full article and he/she does a good job of listing
the differences, but identifying differences and actually understanding
the
implications of those differences are two different things.

The comment above implies that the commentator sees no difference between
a
"structure" and an "object", yet anyone who has worked with these things
in
the real world would understand the essential difference. This is the
difference between Acadaemia and Reality.

H'm! Structure, in procedural, is accessed through a pointer.
Object, in object-based, is accessed through a reference.
Object, in object-oriented, is accessed through a reference;
but also holds a "vtable" to accommodate inheritance and
polymorphism.

The essential difference seems to be the extension of the
structure to add the "vtable" making the object a bigger
structure.
