Abstract

The expressions “now,” “today,” “tomorrow,” “yesterday,” “last month,” “a year ago,” “past,” “future,” “present,” and others like them are temporal indexicals. Temporal indexicals and dates are both quite different from names. Temporal indexicals often play an important part in philosophical arguments about time. An example is this claim of McTaggart's in his famous essay about the unreality of time. Role‐linking is the key to understanding why temporal indexicals are useful. The system of temporal indexicals and system of dates correspond to two different but interconnecting ways people think about things – role‐based and descriptive. Both contrast with a third way, via detached notions. McTaggart's argument for the unreality of time has two sides. According to McTaggart, these two essential properties of time cannot be combined; people's concept of time is incoherent; there is not and could not be anything that fits the conception; time is unreal.
