How Do I Verify That the Earth Existed Before I Was Born?

There's a reason why I believe that Lincoln existed, even though I never met him and it could all be faked. We are all beholden to a much larger discursive projects, a discourses system.

So it sort of gets at the central propositions within what Lakota is called the research program or central proposition within one of Coons' paradigms or something.
