Natural languages all contain constructions the interpretation of which depends upon the situation in which they are used. In Language and Context, Jason Stanley presents a series of essays which develop a theory of how the situation in which we speak interacts with the words we use to help produce what we say. The reason we can so smoothly operate with sentences that can be used to express very different items of information, Stanley argues, is that there are linguistically mandated constraints on the effects of the situation on what we say. These linguistically mandated constraints are most evident in the cases of sentences containing explicit pronouns, such as 'She is a mathematician', where interpretation of the information expressed is guided by the use of the pronoun 'she'. But even when such explicit pronouns are lacking, our sentences provide similar cues to allow our interlocutors to determine the information expressed. We are, in the main, confident that our interlocutors
