Single Idea 6459

[filed under theme 12. Knowledge Sources / B. Perception / 4. Sense Data / c. Unperceived sense-data ]

Full Idea

We do not know, except by means of more or less precarious inferences, whether the objects which are at one time sense-data continue to exist at times when they are not data.

Gist of Idea

We do not know whether sense-data exist as objects when they are not data

Source

Bertrand Russell (The Relation of Sense-Data to Physics [1914], §II)

Book Ref

A Reaction

Note that he actually refers to sense-data as 'objects'. It shows how thoroughly reified they are in his theory if they have the possibility of independent existence. This invites the question 'what are they made of?'

We do not know whether sense-data exist as objects when they are not data [Russell]
'Sensibilia' are identical to sense-data, without actually being data for any mind [Russell]
Ungiven sense-data can no more exist than unmarried husbands [Russell]
