Single Idea 6464

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

Full Idea

The sense-datum is an external object of which in sensation the subject is aware; it is true that the sense-datum is in many cases in the subject's body, but the subject's body is as distinct from the subject as tables and chairs are.

Gist of Idea

Sense-data are usually objects within the body, but are not part of the subject

Source

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

Book Ref

Russell,Bertrand: 'Mysticism and Logic' [Unwin 1989], p.146

A Reaction

This is probably Russell's clearest statement of the nature of sense-data, which are objects within the subjects body, but are not part of the mind. So once again we come up against the question of their ontology. Are they made of neurons?

The 18 ideas from 'The Relation of Sense-Data to Physics'

6483 Russell held that we are aware of states of our own brain [Russell, by Robinson,H]
8244 Sense-data are qualities devoid of subjectivity, which are the basis of science [Russell, by Deleuze/Guattari]
6459 We do not know whether sense-data exist as objects when they are not data [Russell]

6468 There is 'private space', and there is also the 'space of perspectives' [Russell]
6469 Sense-data may be subjective, if closing our eyes can change them [Russell]
6471 The assumption by physicists of permanent substance is not metaphysically legitimate [Russell]
6472 Continuity is a sufficient criterion for the identity of a rock, but not for part of a smooth fluid [Russell]
6473 Physical things are series of appearances whose matter obeys physical laws [Russell]
