Full Idea
We cannot ask, 'Can sense-data exist without being given?' for that is like asking, 'Can husbands exist without being married?'
Clarification
'Given' means presented for experience
Gist of Idea
Ungiven sense-data can no more exist than unmarried husbands

A Reaction
This follows hard on Idea 6460, which introduces the idea of 'sensibilia' for things which are like sense-data, but are not 'given'. This is a new distinction in 1914, which he had not made in 1912.
Related Idea
Idea 6460 'Sensibilia' are identical to sense-data, without actually being data for any mind [Russell]
