  Indexical beliefs are sometimes called self-locating beliefs (Perry 1977), because the beliefs that one has when one knows who one is, where one is, and when one is, are often expressed by uttering sentences containing ‘I’, ‘here’, ‘now’, and other indexicals. Indexical beliefs that can be expressed with ‘I’ are sometimes (following Lewis 1979) called ‘de se beliefs’. (‘De se’ is Latin for ‘of oneself’.) Those expressed with ‘now’ are sometimes called ‘de nunc beliefs’. (‘De nunc’ is Latin for ‘of now’.) Some philosophers hold that indexical beliefs are de re beliefs, which are beliefs of objects. (‘De re’ is Latin for of objects.) For example, some would say that the belief that Mary expresses by uttering ‘You are a philosopher’ to Bill is a de re belief concerning Bill.
