146 Hardegree, Symbolic Logic Definition: If F is a formula of sentential logic, then a substitution instance of F is any formula F* obtained from F by substituting formulas for letters in F. Note carefully: it is understood here that if a formula replaces a given letter in one place, then the formula replaces the letter in every place.
