A Common Ground?

In class on Wednesday we decided that, although Clark's "pragmatic empiricism" is not a neutral ground for naturalists and supernaturalists, it is a common ground, because everybody has access to "this-world" empirical facts. However, I would have to disagree that everybody has equal access to this kind of knowledge. Not everybody is privileged enough to receive a quality education- or any education at all. We are forced to rely on people- parents, teachers, scientists, etc- to give us information. We trust them to give us empirical facts, but we don't have the same access to this information as they do.

Question: How can we even the playing field for people who don't have direct access to empirical knowledge?
