When one looks at the contextually sensitive expressions in natural language, those whose context independent meanings are sufficient by themselves to secure semantic values in context are very much in the minority. Kaplan called such expressions pure indexicals and ‘I’ and ‘yesterday’ may be the only ones (and I worry about ‘yesterday’). Even candidates like ‘here’, ‘now’, and ‘today’ don’t seem to be pure indexicals since e.g. the temporal extent of the semantic value of ‘now’ varies from context to context (‘Let’s leave the party now’ vs. ‘People now watch more content on their computers as opposed to their televisions than they used to’). Similar remarks apply to ‘here’ and ‘today’ (and perhaps ‘yesterday’).
