139 ;;Quote: indiscernibility of identicals--identicals may be substituted in any true statement
139+;;Quote: substitutivity fails for Giorgione = Barbarelli in "Giorgione was so-called because of his size"
144 ;;Quote: 'Necessarily' and 'Possibly' are referentially opaque; depends on wording; e.g., "number of planets = 9" and "9 is necessarily greater than 7"
145 ;;Quote: existential generalization does not apply to irreferential terms; e.g., can not infer that (.thereExists.x)(there is no such thing as x)
148 ;;Quote: can not apply quantifiers to a referentially opaque context; e.g., (.thereExists.x)('six' contains 'x')
156 ;;Quote: with strict modality, quantification does not make sense, nor does modal logic; necessity becomes a synonym for analytic
159 ;;Quote: unrestricted quantification is only useful for truth functions; e.g., mathematics
