 This kind of work is philosophically interesting in its own right. But it is also worthwhile because theorizing about perception commonly aims to address general questions about perception, rather than concerns specific to vision. Hope for a comprehensive and general understanding of perception rests upon extending and testing claims, arguments, and theories beyond vision. One might view work on non-visual modalities as filling out the particulars required for a thoroughly detailed account of perceiving that applies not just to vision but across the modalities. At least three approaches might be adopted, with potential for increasingly revisionist outcomes.
