I like the principle on its face, but what about this example AE
sentence (04)
(forall ((x person)) (exists (y) (and (has x y) (not (part y
EmpireStateBuilding)))))) (05)
True when every person has something that isn't part of the Empire
State Building. The function introduced in the form you suggest would
look pretty contrived -- or at least not so natural as 'fatherOf'. It
seems to me the seemingly "natural" cases arise when we're not talking
about mere existence claims but rather about unique existence claims,
but that's just a guess. (06)
