Boy-Girl fallacy/Geach: shift of the quantifier: from "someone" to "there is a ..".
>Quantification.
"The Third Man" argument/Parmenides/Plato: there is an excellent man to whom we all owe our existence - so we all owe a certain man our existence.
"Some girl"/Geach: one might think that here there is no specific reference.
>Reference.
GeachVs: there can be no "reference to an undefined girl" - there is no such creature.
One must have a certain girl in mind, to use "a" -> "someone", cf. >Objects of thought, >Objects of belief, >Individuation, >Identification, >Mental objects.},
