If you are wrong about numbers, symbols, formulas, etc. in mathematics, you cannot solve math problems properly. Likewise, if you are wrong about the definitions or the information of facts or things in human life, you cannot properly solve the problems that exist in your life.
Humans are having deep deep dreams, trapped in a shroud of ignorance. They are too indifferent to whether the knowledge they have is right or wrong or whether their understanding of the reality is right or wrong. Ignorance, the cause of evil, will eventually bring enormous misfortunes to themselves and their society.
