Do Acquaintance Theorists Have an Attitude Problem?

ABSTRACTThis paper is about the relevance of attitude-ascriptions to debates about singular thought. It examines a methodology reject this methodology, the literature lacks a detailed examination of its implications and the challenges faced by proponents and critics. I isolate an assumption of the methodology, which I call the tracking assumption: that an attitude-ascription which states that s Φ's that P is true iff s has an attitude, of Φ-ing, which is an entertaining of the content P. I argue that the tracking assumption must be rejected, not because it has deflationary consequences, but because it leads to unstable commitments. I also show that there are independent reasons to reject it, because ordinary attitude ascriptions underdetermine even the truth-conditions of the mental-states they ascribe. However, I argue, this does not involve rejecting the claim that attitude-ascriptions express relations between agents and contents. Instead, they state different relations depending on contextual factors other than the nature of the mental-states ascribed.
