Experiences of all kinds have a distinctive character, which marks them out as intrinsically different from states of consciousness such as thinking.

For example, in seeing, grasping and tasting an apple, the subject may be aware of a red and green spherical shape, a certain feeling of smoothness to touch, and a sweet sensation. Such phenomenal qualities are also immediately present in hallucinations. According to the sense-data theory, phenomenal qualities belong to items called “sense-data.” In having a perceptual experience the subject is directly aware of, or acquainted with, a sense-datum, even if the experience is illusory or hallucinatory. The sense-datum is an object immediately present in experience. It has the qualities it appears to have.
A controversial issue is whether sense-data have real, concrete existence. Depending upon the version of the sense-data theory adopted, sense-data may or may not be identical with aspects of external physical objects; they may or may not be entities that exist privately in the subject’s mind. Usually, however, sense-data are interpreted to be distinct from the external physical objects we perceive. The leading view, in so far as the notion is appealed to in current philosophy, is that an awareness of (or acquaintance with) sense-data somehow mediates the subject’s perception of mind-independent physical objects. The sense-datum is the bearer of the phenomenal qualities that the subject is immediately aware of.
Knowledge of sense-data has often been taken to be the foundation upon which all oth
