 Austin is sometimes read as seeking to defend this view of performatives. However, four features of his presentation suggest that his view is not so straightforward. First, Austin presents the issue as concerning the classification by use of utterances of types of sentence, and we have already seen that he is in general sceptical about alleged associations between sentences and their occasional uses. Second, Austin fails here, and elsewhere, to offer serious arguments for his assertion that none of the cited utterances is either true or false. Third, Austin’s assertion is made using the apparently performative form, “I assert … ”—a form that appears, moreover, to falsify the generalisation that performatives lack truth-values. Finally, Austin issues the following warning in a footnote, two pages earlier: “Everything said in these sections is provisional, and subject to revision in the light of later sections” (1962b: 4 fn.1).
