Naming/Denotation/Two-Name Theory/ZNT/GeachVsAristoteles: Incorrect approximation of predication and naming: as if predicates were (complex) names : "on the mat" - E.g. ((s) "The man stabbing Caesar to death stabbed the one stabbed by Brutus.") Additionally, Geach would use a link - Two-name theory: "Socrates is a philosopher" should be true because the thing is named - Vs: "Philosopher" (general term) is not a name for "all (or every) philosopher".
Intentionality/naming/Parmenides/Geach: one cannot name anything that does not exist. (Geach pro) - ((s) existence introduction is not arbitrary, not without premise) - E.g. Geach dreamed of a girl and wants to call it "Pauline" - on the other hand, acquaintance is sufficient - present is not necessary. - Problem: is the girl even more imaginary, if he has not dreamed of her? - Geach: that is a sure sign that this is all nonsense. - Geach with Parmenides: "There is only that what exists." - GeachVsParmenides: However, one can talk about non-existent objects. - E.g. talking about absent friends without knowing that he is dead, changes the truth value, but not the fact that these are sentences. - Imaginary girls are not competing for identification in the dream. - If it is true of no identifiable girl that I dreamed of her, then I have not dreamed of any girl. - Solution: "I dreamed of a girl, but it is not true of a certain girl that I dreamed of her" - Similar to: it is not true of a certain stamp that I want it.
Predication/Geach: can be done without naming: in an if-that-sentence or in an or-sentence, a term P can be predicated of a thing without naming the thing "P". - E.g.: "If that what the policeman said is true, then he drove faster than 60". This does not call the policeman's sentence true. - (> Conditional) - predication/naming: centuries-old error: that the predicate is uttered by the thing. - Frege: Difference assertion/Predication: to name a thing "P", a sentence must be asserted! But a property is also predicted in a non-assertive sub-clause (subset). - Therefore, naming by predication must be explained, not vice versa.
