 Let’s start with (1)–(3). Austin 1950a is ostensibly responding to a proposal in Strawson 1949 according to which the function of the predicate “is true” is to facilitate the performance of acts of affirmation or agreement, and not to describe things—e.g., statements—as possessing the property of truth. For short, Strawson claimed that “is true” has a performative rather than a descriptive function. And he accused his opponents of committing the descriptive fallacy: the alleged fallacy of treating expressions, or aspects of the use of expressions, that really serve performative purposes as having (only) a descriptive  purpose.[4]  One of Austin’s aims was to defend the view that the predicate “is true” has a descriptive function (perhaps in addition to its having one or more performative functions). In pursuing that aim, Austin also made a number of distinctive proposals about the descriptive function of the truth  predicate.[5]
