 And amodal completion is partly constitutive of perception per se. The vast majority of our perceptual states involve amodal completion. Take the visual sense modality: when you look around, you see objects further away from you partly occluded by objects closer to you. So your perceptual system amodally completes these occluded bits of the objects further away from you. But amodal completion is also involved in the representation of the unoccluded objects – you don’t get direct sensory input from the back side of these objects, nonetheless you represent them perceptually – which means you amodally complete the back side of all three-dimensional objects (Bakin et al. 2000, Ekroll et al. 2016). In short, amodal completion is partly constitutive of perception per se. And if amodal completion is indeed a form of mental imagery, then we have reason to think that mental imagery is partly constitutive of perception, just as the charitable interpretation of Kant suggests.
