Fiction/Existence/Ontology/E.g. Chesterton "The Missing Mr Glass": hearing impairment: "I missed a glass" - Geach: then the question is no longer whether predicates may be attributed - intentional verbs such as "adore" "dream of", "seek" are not well understood - if descriptions are replaced, the truth value may change or may not change - how do you find out if two worship the same God?.
