School largely teaches children to regurgitate information from text books, but very rarely, if ever, does the teacher encourage pupils to question the information in those text books.
Is it any wonder, then, that those same children who grow up to be adults never question what they are told by the government and mainstream media and merely regurgitate what they are told on the previous nights' news?
The government and media, like the teachers in school, are deemed the ultimate arbiters of truth because most adults have been conditioned, through years and years of obedience training at school, to take authority as truth rather than truth as authority.
"They must find it difficult, those who have taken authority as truth, rather than truth as authority." - Gerald Massey
