Can any of our thoughts truly be original and unique?

Yes. All thoughts must originate somewhere, so somebody must be having original and unique thoughts somewhere.

jabberwacky: Yes. But it's possible that thoughts from a man would be told by another man.

user: Yes, but some man would have to think the thought before any other man can think it. So, even if our thoughts aren't original, somebody's thoughts are original.

jabberwacky: You think so?

user: Yes I do. If I didn't think that I wouldn't have written it.

jabberwacky: Then you are either philosophically dull and unintentionally arrogant as a result, or just really boring.

user: Actually, I'm all three.
