Substitution VII 29
Substitutability/substitution/QuineVsLeibniz: the strength of this requirement varies with the richness of the language -we need both single- and multi-digit predicates, truth functions (not, and, or, etc.), classes, classes of classes, descriptions, singular term - this language is then extensional: any two predicates that match extensionally (are true for the same object) are substitutable salva veritate - but that does not secure cognitive synonymy.

Replace/substitution/Quine: if in a statement that has been substituted for "Fx" free variables other than "x" occurr, then they may not be such that fall under the scope of quantifiers that occur in the scheme in which the substitution was made.
