‘Rule theory’, or the claim that a simple rule is sufficient to give the meaning of I, is a myth. Theorists have not shown that it is even possible to say what this rule is, what it means, what it determines, or what functions as its context. No such rule could be sufficient to give the meaning of I because there are areas which it does not cover, there are areas in which it applies but is insufficient, there are occasions on which it should not be applied, and there are occasions on which it cannot be applied.
