But there are three things to distinguish, not just two.  Following
is an excerpt from a previous note I wrote on this thread:    (02)

Category B includes any kind of language or logic.  Category C
includes any theory about the world by ontologists, by scientists,
or by engineers who apply ontology or science to a particular task.    (04)

But we have to recognize that the world A is not identical to
the way B we talk about it or the way C that some scientists,
engineers, or ontologists characterize it.    (05)

Every mapping to the world A from any language B or any theory C
is an *approximation* whose usefulness depends on the application.
When the application changes, we may need to use a different
approximation -- i.e., different theory of ontology or science.    (06)
