Full Idea
Russell says one won't find the present King of France on the list of bald things, nor on the list of things that are not bald. It would seem that this gives rise to a violation of the law of excluded middle.
Gist of Idea
If the King of France is not bald, and not not-bald, this violates excluded middle

A Reaction
It's a bit hard to accuse the poor old King of violating a law when he doesn't exist.
