I think this muddies things. You're relying on the common understanding of "attempted speech act", but that's an emergent concept some way removed from the relevant rules. Meanwhile you're trying to establish a very basic aspect of the interpretation of statements. It's an abstraction inversion. How about: A statement that the speaker is performing an action by means of a public message can be true or false as for any other kind of statement, and in particular it is false if the speaker does not thereby successfully perform the action described. -zefram
