[catalogued under 12. Knowledge Sources / B. Perception / 4. Sense Data / b. Nature of sense-data]

Full Idea

It is hard to individuate sense-data, saying where one ends and the next begins, and hard to say whether they can change; are they substances, qualities, events, or what?

Gist of Idea

Where do sense-data begin or end? Can they change? What sort of thing are they?

A Reaction

The problem is not that these questions are unanswerable. The answer seems to be either that they are physical and external, or that they are mental and internal, and that there is no ontological space for them between the two.
