Gertler's acquaintance approach to introspective knowledge and internalist requirements for reasons

Abstract

ABSTRACT Gertler argues that, in some introspective judgments about experience, phenomenal reality intersects with one's grasp of that reality to the effect that one can have knowledge by acquaintance. This new version of the acquaintance theory depends on the idea that some introspective judgments about experience can be justified by the fact that the phenomenal property of an experience is a component of the introspective judgment about the experience. The goal of this paper is to show that even this most promising version of the acquaintance theory is not successful. For this goal, in particular, I argue that even if we grant that, in the relevant cases, the phenomenal property of an experience is a component of an introspective judgment, this fact can hardly play the epistemic role that Gertler envisions. I establish this on the basis of two internalist requirements for reasons, namely, the evaluability condition and the endorsement condition. On the former condition, a reason for justifying a judgment must be the kind of thing that can be evaluated as correct or incorrect. And on the latter condition, having a reason for justifying a judgment requires that the subject endorse the reason as correct.
