Factive and nonfactive mental state attribution

Factive mental states, such as knowing or being aware, can only link an agent to the truth; by contrast, nonfactive states, such as believing or thinking, can link an agent to either truths or falsehoods. Researchers of mental state attribution often draw a sharp line between the capacity to attribute accurate states of mind and the capacity to attribute inaccurate or “reality-incongruent” states of mind, such as false belief. This article argues that the contrast that really matters for mental state attribution does not divide accurate from inaccurate states, but factive from nonfactive ones

On the Nature of Presupposition: A Normative Speech Act Account

In this paper I provide a new account of linguistic presuppositions, on which they are ancillary speech acts defined by constitutive norms. After providing an initial intuitive characterization of the phenomenon, I present a normative speech act account of presupposition in parallel with Williamson's analogous account of assertion. I explain how it deals well with the problem of informative presuppositions, and how it relates to accounts for the Triggering and Projection Problems for presuppositions. I conclude with a brief discussion of the consequences of the proposal for the adequacy of Williamson's account of assertion
