Nevermind my last comment.

The email threading in OSX Lion made it appear that Graham was asking why we care if Entity is a concept in the model, not whether we care about the general question of whether we can know that two BOBs are characterizations of the same entity.

Apologies,

In the initial draft, I think that the editors intentionally avoided defining the term "entity" as part of the vocabulary. I don't suggest defining that term, but having a means by which one would know that two Bobs are characterizations, possibly different, of the same entity, e.g., using an assertion like "sameEntity(bob1, bob2)".
