Throughout our lives, we impact the world in various ways, we leave footprints on the ground, we cast shadows and show up in mirrors, and form ideas in people's minds, but even though those effects look and act like we do, they aren't truly us, they don't actually experience the world.

There is an equivocation there. The Mark Twain that appears in his book is not the same as the Mark Twain that wrote his books. It's two entities bearing the same name. It's a category error to say the two are the same, it's conflating the idea of a thing with the thing the idea represents.

We do of course both have an idea of Mark Twain the dead author, and Mark Twain the literary character, and that may muddle and be the same idea in our mind, but that idea is not the same entity as Mark Twain the person. Unlike a person, an idea does not have subjectivity, it does not experience.

You can write a book where the character Mark Twain has a conversation with Harry Potter, even though Mark the human could never meet Harry the fictional character. If people and characters the were truly the same thing, wouldn't they be subject to the same constraints and limitations?
