Reason and the clash of worldviews
Once new knowledge and spiritual truth get into our heads, however it is that it happens, reason is now available to do its work. Even though reason works well within both the spiritual and physical dimensions in the confines of the same wordview and knowledge set, I believe it cannot work well across different knowledge sets and worldviews. Reason is inexplicably tied to it’s bearer’s presuppositions and set of knowledge – removed from them it has no context and therefore no effectiveness, like a hammer without a person.
It seems that for people of differing worldviews to criticize each others beliefs using reason, they are jumping the gun. They must instead start by examining each other’s worldviews that reasonably lead to their beliefs before progressing to the beliefs themselves. Both parties are to a lesser or greater degree reasonable according to their presuppositional framework, so the frameworks are the only things that people of opposing worldview can argue about. For reason to work across frameworks, the parts of the frameworks that are agreed upon must be the knowledge that it works off of. In the case of the deist and the atheist, the common denominator would be a belief that the existence of empirical evidence is required for something to be true.
