- The technical sense of "having semantics", is to be possessed of an
- interpretation, either extensional (truth functional) or intensional
- (propositional). Thus accepting your point is tantamount to accepting
- a choice between ruling that meta-ZFC discourse is necessarily
- meaningless, or that your understanding of its intended interpretation
- is wrong.

- Partial expression is enough for my purposes. In any case, the

- inscrutability of reference.
