Millican (1994) "Central to the [Strawsonian tradition] is the distinction between a sentence and what is said by a sentence - Strawson initially called the latter a use of a sentence, and sometimes a proposition, but his most frequent term for what is said, which Wolfram consistently adopts, is the statement expressed." Millican, Peter (1994). "Statements and Modality: Strawson, Quine and Wolfram"(PDF).
