The brain function of abstraction is one of the cognitive functions are believed to work in conjunction with many other neural processes to create your belief systems (among other things). Abstraction acts as a doorway between direct perception and consciousness, for humans depend on concepts, labels, and words to shape their awareness. This is problematic when it comes to spiritual matters, which, by definition, refer to realms that have no physical reality. Newberg points out that young children can form categories for concrete objects, but they have enormous difficulties with abstract concepts such as freedom, fairness, right and wrong, or God. The brain transforms reality into abstract categories and labels, and these labels are intangible beliefs, assumptions about a world that cannot be directly perceived. In this sense, labels, beliefs, and reality are one and the same. If an ability to abstract is lost, the individual likely will end up living in a state of perpetual confusion, unable to navigate in the world, and unable to form beliefs.
