A crucially important adequacy test of any theory of speech acts is its ability to handle performatives. This paper provides a theory of performatives as a test case for our rationally based theory of illocutionary acts. We show why "I request y o u . . . " is a request, and "I lie to you that p" is self-defeating. The analysis supports and extends earlier work of theorists such as Bach and Harnish [1] and takes issue with recent claims by Searle [10] that such performative-as-declarative analyses are doomed to failure. . | Performatives in a Rationally Based Speech Act Theory Philip R.

How and when is this possible Not all verbs can be uttered in the first-person present tense and thereby make the sentence true. In general the successful verbs seem to correspond to those naming illocutionary acts but not to perlocutionary ones such as frighten. But even some illocutionary verbs cannot be used performatively . I lie to you that I didn t steal your watch is self-defeating 12 . So which verbs can be use performatively and in Searle s words 10 how do performatives work Any theory of .
