A Theory of Sense‐Data

Summary

A sense-datum theory of perception is developed and defended. Perceptual experience involves acquaintance with sense-data: private particulars that have all the properties they appear to have, are common to perception and hallucination, constitute phenomenal character, and are analogous to internal pictures. Unlike classic theories, sense-data are neural states presented first-personally, their sensational qualities differ in kind from external objects' sensible qualities, and they are the vehicles of perception rather than its objects. The view is argued to be a live contender in philosophy of perception.

Abstract

ABSTRACT I develop and defend a sense‐datum theory of perception. My theory follows the spirit of classic sense‐datum theories: I argue that what it is to have a perceptual experience is to be acquainted with some sense‐data , where sense‐data are private particulars that have all the properties they appear to have, that are common to both perception and hallucination, that constitute the phenomenal characters of perceptual experiences, and that are analogous to pictures inside one's head. But my theory also diverges from conventional sense‐datum theories in some key respects: on my view, (1) sense‐data are neural states presented first‐personally, (2) the sensational qualities of sense‐data differ in kind from the sensible qualities of external objects, and (3) sense‐data are the vehicles in virtue of which we perceive, rather than the objects that we perceive. I argue that this package of claims is appropriately labeled ‘sense‐datum theory’, and that the resultant view ought to be a live contender in contemporary philosophy of perception.
