Perceptual warrant and internal access

Abstract

Perceptual beliefs that categorize objects can be justified by demonstrating basic properties (eg shapes) of the objects. In these justifications, perceptual justifiers have different contents to the beliefs they justify. I argue that the justifications are not inferential. Subjects are unlikely to have bodies of beliefs adequate to inferentially justify the beliefs they actually form on the strength of their object recognition abilities, especially when recognition depends on stimulus-dependent retrieval of visual memories. Instead, I argue, the justifications exploit a partial awareness that subjects have of states and processes involved in object recognition. As such, they show that subjects have a degree of internal access to the principles of externalistic perceptual warrant, and to the features of perceptual states that give them justificatory force on externalistic accounts. The justifications themselves are evidential, but in order for them to have any justificatory force, they have to be placed in an externalistic framework for perceptual justification. I conclude that this form of justification shows that subjects have a degree of insight into why their perceptual experiences justify their beliefs.
