Full Idea
A fact may be an object and an extension (Quine's view), or a property and a set of properties, or an object and a property; the view I favour is the third one, which seems the most natural.
Clarification
The 'extension' is the set of objects which qualify
Gist of Idea
Facts are object-plus-extension, or property-plus-set-of-properties, or object-plus-property

A Reaction
Personally I tend to use the word 'fact' in a realist and non-linguistic way. There must be innumerable inexpressible facts, such as the single pattern made by all the particles of the universe. McGinn seems to be talking of 'atomic facts'. See Idea 6111.
