Logic for 'Flakey' Constants Karen, John, Flakey,
Hall, Kurt, f1, o1, o2 Predicates R binary S
binary Functions F unary Proper Axioms ?x,y
R(x,y) ? F(x)F(y)

Semantics Example I
Domain 'Flakey' Objects D Karen Meyers, John
Bear, Flakey, Hall, Kurt Konolidge, the file,
office-1, office-2 Relations has (Karen
Meyers, the file) office (John Bear,
office-1), (Karen Meyers,
office-2) Functions f ? f(Karen
