How does the brain recognize that it should have this feeling?&quot;<p>If we take the idea seriously that the universe is unified and all knowledge is unified, then it would be safe to treat the universe as a single entity.  AKA everything is related to everything else in a whole host of mundane and non mundane ways that human beings are not aware of given the limits on the human brain&#x2F;body and the time and energy required to process that information.  AKA all the truth is there (the universes structure and its relationships).
