Presence, objecthood, and the phenomenology of predictive perception.

Can perceptual presence be explained by counterfactually-rich predictive models linking perception and action? Considering an unusually rich range of responses to this idea has led me to (1) re-emphasize the core conceptual commitment of "predictive processing of sensorimotor contingencies" (PPSMC) to predictive model-based perception, (2) reconsider the relationship between presence and objecthood, and (3) refine the phenomenological target by differentiating between perceptual presence and the phenomenology of absence-of-presence, or "phenomenal unreality." It turns out that this requires blue-sky thinking.
