The mind is vast and while we are on earth corresponds to the structure the physical brain. With trillions of connections, we can assume the brain is organized. With any complex structure you need a hierarchy, some type of organization that sorts the general from the specific. Thus we can assume that the mind has its hierarchy, the fundamental beliefs are at the top and details are near the bottom.
There are different hierarchies. For example, Maslow's Hierarchy provides a context of what is important, ranging from dealing with danger to the highest levels of creativity. Another hierarchy is the depth of conversation that may range from "elevator talk" to deep abstractive conversation.
