IX—Unmistaken: Imaginative Perception and Illusion

Abstract Sometimes what we perceive appears other than it is. The term ‘illusion’ is often used to capture the broad variety of cases in which this occurs. But some of these cases are better described as cases of imaginative perception—cases in which what we perceive appears as we imagine it to be. I argue that imaginative perception is to be sharply contrasted with illusions variously conceived as cases of misleading appearance and cases of perceptual error. By removing the blanket term ‘illusion’ from our description of such cases, we can better see the underlying complex of cognitive processes they involve.
