A thing may not "know" itself without recursion. Thus, some unknowns, contrary to popular logic, are still unknowns. We don't know how magnets work and it may be that our brains use how they do work in a specific way to do what they do. On the other hand, they may not. It's the concept of holding both of these "facts" as eventual truths (irrationally resolved in the future) in one's mind at the same time that leads to dissonance. That's a good excuse for the scientific process, if there ever was one.
