Full Idea
We cannot assume that every meaningful predicate necessarily expresses a property that some entity could possess. The predicate 'is non-self-exemplifying' is meaningful, yet it would be contradictory for there to be any such property.
Clarification
The predicate comes from Russell's Paradox (Ideas 6407 and 7701)
Gist of Idea
Not all predicates can be properties - 'is non-self-exemplifying', for example

A Reaction
This clinches what I would take to be a foregone conclusion - that you can't know what the world contains just by examining the predicates of the English language. However, I suppose predicates are needed to know properties.
