  Various theorists classify indexicals into types, depending (roughly) on how their references and contents are determined in a context. Kaplan (1989a), for instance, distinguishes between pure indexicals and true demonstratives. The pure indexicals, he says, include ‘I’, ‘today’, ‘tomorrow’, ‘actual’, ‘present’, ‘here’, and ‘now’. The true demonstratives include ‘he’, ‘she’, ‘his’, ‘her’, and ‘that’. Kaplan claims that the reference and content of a true demonstrative, in a context, depends (roughly) on the speaker’s accompanying demonstrations or intentions. For example, Kaplan says that the reference and content of ‘that’ in a context is determined (in part) by the speaker’s pointing gestures or by the speaker’s intention to refer to a particular object. The reference and content of a pure indexical does not. For example, the reference of ‘I’ in a context is always the speaker, whether or not she points at herself, and the reference of ‘tomorrow’ is always the day after the day of the context, no matter which day the speaker intends to refer to.
