  • Kevin S. Lynch asks, Q: Is identity a consequence temporal continuity? One of the main motivations of ISO 15926 seems to be a desire to ascribe an unchanging identity to an entity/object that changes substantially over time, e.g. the plastic cup. Philosophers happen to love this problem, and so we can also draw on the Ship of Theseus problem (Plutarch, Plato, Hobbes), the Lump of Wax problem from Descartes, the brain in the vat problem, etc. Testing this conundrum in ISO 15926, how would one properly model the temple of the Golden Pavilion in Kyoto, for example? The temple has undergone total destruction and reconstruction several times through its history, and yet it retains its identity as The Golden Pavilion (i.e. it is temporally discontinuous, and yet we don’t automatically say that it is a “different” temple). Also, less catastrophically, the building has had substantial repairs and replacements to the extent that over a 100-year period the material parts of the structure have all been replaced, and it is no longer the “same” building. Is this the sort of “difficult case” that the standard was intended to address? In the language of ISO 15926, the definition for <stream> seems to argue that only continuous existence can serve as a basis for identity: “A <stream> is a <physical_object> that is material or energy moving along a path, where the path is the basis of identity and may be constrained…” Can there be identity when there is no <stream>? While it may be convenient to exhibit objects in a 4D spacio-temporal grid, this is not equivalent to establishing an ontological identity.    (K4G)
  • The ISO 15926 definition for <class> declares: “The identity of a <class> is ultimately defined by its members. No two classes have the same membership.” ...Q: Can the identity of a <class> be assured by the stable continuity of its members? (Plato is lurking in here somewhere — in the insistence that classes should belong to the intelligible world of unchanging forms while our sensory perceptions are hopelessly constrained to the Heraclitean world of temporal changes and appearances.) Does the totality of membership constitute the essence of what is meant by a <class>, or do classes express something else? When we talk about types, universals, kinds, categories, etc., I think it is a mistake to assert that the identity of a class can be inferred from its members. For instance, the class of all dead things in a 4D Ontology would contain essentially all entities (i.e., everything has been dead, will be dead, or is dead). It is very stable in that it is always constituted by the same membership (everything), but there is no “identity” to be inferred from a class that contains all things.    (K90)
