When I use the name "Frodo" I am referring to the hobbit, not to the word "Frodo" or my idea of Frodo. Realism is not required for words to refer to more than just our words and our ideas.

Hobbits are fictional characters. Being fictional characters, they exist only as ideas in the imaginations of humans. So any true proposition that refers to hobbits, say "hobbits are short", is necessarily reffering human ideas of hobbits. If one wants to claim that hobbits can refer to things outside the realm of human imagination, such as the proposition " the dude that lives next door is hobbit", I would have to insist that they are just mistaken.

Oh , also, is this yaha? If not, I'm really confused.
