Re: [ontolog-forum] The "qua-entities" paradigm

Pat:

re Matthew's statement that 

<<<Each grain of sand exists in the real world and has identity ...>>>

re Pat's comment, I do not agree that Matthew clearly meant the exact opposite of what Rich thought he meant. What is clear is that to say that something "in the real world ... has identity" is not clear. 

On an epistemological interpretation, it would seem to mean something like "can be identified", where it is some kind of conscious agent who could do the identifying. With Rich, I have no problem with this interpretation.

On an ontological interpretation, having identity is mysterious. Does a grain of sand "have" an identity in the same sense that it has size and weight? Or in the same sense that it has a location in space and time? If not, what does "has identity" mean? 

Perhaps you can clear up the mystery?

The best case I could make for an ontological interpretation would be that Matthew (and you?) are, whether consciously or not, expressing your agreement with Leibniz's principle of the identity of indiscernibles. That is indeed an ontological claim, not just an epistemological one. But it doesn't involve claiming that there is a property/attribute/quality called "identity" that physical things have.

So is Leibniz's principle what Matthew (and you) mean? If so, it certainly wasn't clear to me, at least, from Matthew's statement. 

If that isn't what you mean, but what you do mean is not what I called the "epistemological interpretation" above (approximately Rich's position, I think), then what is it that Matthew meant, and that is apparently clear to you?

Another avenue of response for you is some variant of saying that, by just using "good old common sense", what Matthew means is indeed clear, and that what I've suggested here is just philosophical hair-splitting which only obscures otherwise plain and clear meanings. But, as we are all ontologists, and if, as John Sowa's work makes completely clear (8>), classical ontology and ontology engineering are both about "ontology" in much the same sense, then I would hope that you don't propose some variant of this response.

Regards,

Tom

He said that the identity of each grain of sand is IN THE REAL WORLD, WHETHER OR NOT YOU ARE INTERESTED IN IT. He did not say that it depends upon your perspective. You and your perspective could cease to exist, and the grains of sand would still be real, in the real world, with their identities intact. The identities of things in the real world do not depend upon your or anyone else's perspectives upon them. They are, you see, REAL.

I was not trying to convince you of anything, nor expressing "my take". I was making the point that you had completely misquoted, or misunderstood, what Matthew actually SAID. Whether you agree with what he said is another question altogether, and one I am not particularly interested in; but unless you actually understand what others are saying, there is little point in debating with them.
