It seems "representing" is a abstraction that is a bridge too far for you mental ability, and that might be the same problem with "Truth", since there is a abstract nature to what Truth is, as Truth can exist without having anything to actually sense to make it occur. That your mind can't handle abstractions would explain a lot of your problems.
