Substitution: in a formula, a symbol can be substituted for another symbol under certain conditions. E.g. If a constant is substituted for a variable, a propositional function becomes a statement. See also Substitutability, Generality, Validity, Statements, Propositional functions, Fine-grained/coarse-grained._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

W.V.O. Quine on Substitution - Dictionary of Arguments
VII (b) 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 terms. >Classes, >Descriptions, >Truth functions, >Predicates, >Richness, >Expressiveness, >Singular terms. 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. >Extensionality, >Extension. --- VII (c) 56 Substitutability/Quine: question salvo quo? Something is always changed. --- IX 9 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._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
