Truth 1: Reality and the Truth Are Separate.
The truth is not reality nor a reflection of reality. Reality is not the truth nor a reflection of the truth.
Reality is how we perceive the world. It is guided by personal beliefs and the dominant social systems. No two people will agree upon reality in all aspects, but social systems ascribe rules onto reality that we submit ourselves to.
One such rule is that the truth can be found from studying reality. Imagine a person sees a ghost, and concludes ghosts must exist. Someone who is in the same room as them may not see the ghost, and thus concludes ghosts do not exist. The very fact that two people can disagree on the existence of something means our senses cannot be trusted to know what is real. The dominant social system demands that something is true if it can be measured by most people who have the correct equipment. Yet, to the person who sees the ghost, the ghost is real.
The truth is independent from reality. It stands without reference to and often in spite of social systems. It cannot be determined from reality as reality is biased by our senses and beliefs. The truth has roots in the physical and the psychic. The physical can be measured. The psychic cannot. The truth will always be true regardless of reality, although social systems may insist that the truth are lies.
The world is not flawed, only our senses and beliefs are flawed, and as such we should design our belief systems around the truth and not reality.
