Full Idea
Realists feel that the one-place predication 'a is F' leaves something unexplained, yet all that is offered is a two-place predication (a relational statement). There is an equal problem about 'a having F-ness'.
Gist of Idea
Realism doesn't explain 'a is F' any further by saying it is 'a has F-ness'

A Reaction
I think this is a key argument on the nominalist side - the denial that the theory of universals actually makes any progress at all in giving an explanation of what is going on around here. Platonist have the problem of 'partaking'.

8503 | The particular/universal distinction is unhelpful clutter; we should accept 'a is F' as basic [Devitt] |
