Is belief necessary because the world is not real? Believing-in would not be necessary if it was.
Humanity has taken a necessary component of participating in the illusion and made it a dogma—rewarding the creature with promises for correct belief (there are none) Such belief is even considered more important than correct action.
So, why so much attitude when all beliefs have contradictory behaviors as bed-mates?
If you believe our ontology rests in biological evolution and the right mix of minerals creates intelligence, that natural selection leads to the fittest for survival, how can one simultaneously believe that humans are destructive viruses and the world should be changed—that the world would be a better place if humans never existed? We are simply results in a petri of selfish genes—
You are the result of billions of years of imperfect, immutable, unguided change with the best chance of survival. If you believe this, nothing that has ever happened is in error, so why fight it? Why fight anything? There are no mistakes in nature, yet one thinks he can outsmart his own organism. Thats funny!
If you believe that the universe is a self governing organism, that everything that happens happens to “itself” (god) then you must believe things are exactly as they can be, or should be (or you want it to be) so why the division if all this variety is simply an interesting drama?
If you believe there is a an all-wise, all-knowing creator that is in complete control (even ordains our elected officials since “before the world was”) that he will make you a heaven if you simply believe, why all the gun collecting, racism, and nationalism? Why postulate a god and then immediately make it a meaningless assertion? Is he is really in control? Why do you have no faith in your faith? Why choose to believe something that has no bearing on the outcome of anything?
I could go on, but why the fighting when every religion, philosophy, or science, ultimately shows that there is nothing that can be done that is a mistake, or perfectly natural?
If science really believes natural selection is true, religion is a perfectly natural progression of evolution. Science then would be right about their science but wrong to fight religion. If evolution is true, why fight it?
And finally, why is belief so prevalent around the world? Is it because it isn’t real? There is nothing to hold on to. Is it possible the ground of being is strictly illusory? If not, why the need to believe in everything? Why the world of beliefs if there is such a thing as reality?
Beliefs are so important that they are protected by law—is like protecting a spirit with proper documentation.

The world must be believed to be seen…”Belief makes one fight. Fighting makes one strong—the selfish gene is in control after all”
