 According to A. D. Smith (2002), perception requires the possibility of achieving different perspectives on perceptible objects through self-movement. This comes with the existence of perceptual constancies (see Burge 2010 for the importance of perceptual constancies). However, unlike other perceptual objects, the body cannot be felt from different perspectives. Smith thus claims that bodily sensations are mere sensations; they do not count as perceptual. Likewise, Matthen (forthcoming) distinguishes within the sense of touch the tactual sensation on one’s skin and the haptic perception of the object. These are two distinct types of experiences and only haptic experiences are truly spatial, and thus truly perceptual. On the contrary, Martin (1992) claims that there is no reason to draw a distinction within tactile experiences: one can simply shift one’s attention from the bodily side to the exteroceptive side of the same perceptual experience (see also O’Shaughnessy 1989). Nonetheless, according to Martin (1992), touch differs from vision insofar as it has no unified tactile field equivalent to the visual field (see also Richardson 2013; Hopkins 2011).
