In a certain picture of cooperative conversation, ‘silence gives assent’. However, in adversarial contexts, structured by power dynamics, silence may be a powerful expression of dissent. To reconcile these opposite interpretations, I propose an analysis of silence as the expression of a default attitude. Given pragmatic cues, participants infer the cooperativeness of conversational settings. Depending on cooperativeness, they assign a default attitude (of assent, of suspension of judgment, of dissent) to other participants, that they take intentional silence to express. This analysis takes the main effect of speech acts to be proposals to update the conversational Common Ground, and highlights the necessity of assent in conversational updates.

A speaker can express the same thought, true under the same conditions, while using different expressions and grammatical constructions. According to Frege, these are differences in colourings. Colourings may convey additional contents; in that, they resemble Gricean conventional implicatures. Sander (2019) argues that Gricean implicatures do not subsume the category of colourings, as some colourings do not communicate their content. I show that this argument relies on a notion of communication focused on the speaker's intentions. But a notion of communicative intentions where a speaker is responsible for the intentions her audience ascribes her possible. Under this notion, since so-called non-communicative colourings trigger specific inferences, a speaker who uses them communicates these inferences. Therefore, I vindicate the communicative role of colourings with content.
