Full Idea
Russell rejected Frege's sense/reference distinction, on the grounds that, if reference is mediated by sense, we lose the idea of direct acquaintance and succumb to Descriptivism.
Gist of Idea
Russell rejected sense/reference, because it made direct acquaintance with things impossible
Source
report of Bertrand Russell (On Denoting [1905]) by François Recanati - Mental Files 1.1
Book Reference
Recanati,François: 'Mental Files' [OUP 2012], p.5
A Reaction
[15,000th IDEA in the DB!! 23/3/2013, Weymouth] Recanati claims Russell made a mistake, because you can retain the sense/reference distinction, and still keep direct acquaintance (by means of 'non-descriptive senses').
