The integration problem for naive realism

This paper makes explicit the basic problem perfect hallucinations pose for perceptual naive realists, more fundamental than the well-trodden Screening-off Problem. The deeper problem offers the basis for an overarching classification of the available naive- realist-friendly approaches to perfect hallucinations. In the course of laying out the challenges to the different types of response, the paper makes a case for the superiority of a particular approach to perfect hallucinations, on which they would be understood as a special kind of perceptual anomaly—arising from a secondary mode of perceptual processing.
