An Axiom
An axiom is a statement or premise that is thought to be self-evident or universally true, meaning it does not need to be proven or questioned. Once people have accepted a thought system, they rarely question the basic assumption upon which it is based. They accept it as universally true, and that is why they are so absolutely convinced that their thought system is the only right one and has ultimate authority.
Once an axiom defined, it is claimed to be an absolute truth. Then a thought system upon that “truth” is built or around it. As long as you do not question the basic axiom, you will be absolutely convinced that your system is superior to any other. You will have the perfect excuse for ignoring conflicting views. You might even feel justified in seeking to destroy such ideas or the people who promote them. The excuse is, of course, that since your thought system is based on an infallible truth, any opposing views must – per definition – be false.
Fundamentalist Christianity
Fundamentalist Christianity is based on an axiom which states that the Bible is the infallible word of God, meaning that it has the highest possible authority. Anything conflicting or going beyond the Bible must be false. Another axiom is that the Bible should be “interpreted” literally (of course, the words “literal” and “interpretation” are contradictory), meaning that a fundamentalist church will claim that its particular “literal” interpretation of the Bible is the only true one. All conflicting interpretations must therefore be of the devil, which means fundamentalists have the perfect excuse for ignoring them. Of course, they fail to see that they are using the exact same logic that the scribes and Pharisees used against Jesus Christ when he challenged their thought system and "truth", axiom it is based on.
Materialistic philosophy
It holds as an axiom that science – for example through the theory of evolution – has proven that there is nothing beyond the material universe, thus there is no God. Again, such people have the perfect excuse for ignoring any contradictory evidence – even when produced by science itself – since it is just superstition or the subjectivity of the mind.
Political thought systems
Marxist belief that the driving force in society is the struggle between the ruling class and the workers. Again, any conflicting system must be false, and this leads to the struggle between capitalism and communism. Of course, capitalism is also a thought system based on the axiom that capitalism represents free enterprise, as opposed to a communist system with state ownership and control. Obviously, capitalism is simply another elitist system (as is communism) and thus has nothing whatsoever to do with freedom.
Conclusion
All of these systems cause people to accept the underlying axiom as something that should never be questioned. This means that the systems form closed boxes, and once people accept the underlying axiom, they can remain trapped indefinitely—unless they dare to question the unquestionable.
Any thought system has the perfect way to prevent people from questioning its axioms. That way is to engage people in the struggle against the enemies of the system. This can keep people’s minds so preoccupied that they never actually get around to questioning the underlying assumption of their own system.
Any thought system in this world is based on an axiom, an assumption, a mental image. Such a system may still help you make progress by expanding your understanding, as many spiritual based thought systems can do. Yet any such system sets limits for how far you can go in your quest for ultimate truth—for in order to remain within the system, you cannot question its basic axioms. You will not go beyond those limits until you are willing to question the basic assumptions upon which the system is built. This is the difference between a religious person – who never questions the basic tenets of his or her religion – and a mystic who accepts no mental box thought system.
Most people tend to believe that if there is a conflict between two belief systems, one must be right and the other wrong. The reality is that people on both sides of a dualistic debate are out of touch with reality. Because axiom is always false by definition, you need it because you are not experiencing factual reality, you are speculating, imagining, thinking what reality is like.
As long as people’s conscious selves cannot see through the dualistic logic, they are stuck in playing the ego game of seeking to prove that their side is right, constantly being challenged by those in the other polarity who, although they are obviously "wrong", still insist that they are right.
What often makes it even more harder to get out of this mental prison is that such a belief system can indeed have correct elements that closer in describing reality or state some fact of life. For example.
Marxism claims it's workers right to have equal pay and treatment and that worker must have certain inalienable rights. This is universally true and has nothing to do with ideology of Marxism. Political ideology can claim that all people have a right to vote, this is also universally true despite any political system. Ideology of scientific materialism can claim universe had a beginning, this is again been true despite been discovered or not and accepted by scientists. Christianity may claim existence of a soul, again this is simply points to existence of a mind and psychology and this is irrelevant for what religion person follows.
