Michel de Certeau liest Jules Vernenot refer to models but only to provability within the system reads as follows: a deductive system is (.) . iff for every formula ., formulated in the language of the system, with no free variables either . or ~ . is provable in the system (see “Predicate logic” §5.2.1). This entry deals with semantic completeness.

Consistency,re exists an underivable formula. To prove the equivalence, assume that . is underivable and . is abritrary. If both . and ~ . were derivable then . would be derivable as well using modus ponens from the propositional tautology (Duns Scotus law): ~ . ⊃ (.⊃ .).
