Assertion

Assertion is here approached as a social practice developed through cultural evolution. This perspective will facilitate inquiry into questions concerning what role assertion plays in communicative life, what norms it is subject to, and whether every viable linguistic community must have a practice of assertion. The author’s evolutionary perspective will further enable us to ask how assertion relates to other communicative practices such as conversational implicature, indirect speech acts, presupposition, and, more broadly, the kinematics of conversation. It will also motivate a resolution of debates between conventionalist and intentionalist approaches to this speech act by explaining how those who make assertions can embody their intentions to perform an act of a certain kind. The chapter closes with a discussion of how assertoric practice can be compromised by patterns of malfeasance on the part of a speaker and by injustice within her milieu.
