According to Faber, why are books hated so much?

Basically books can reveal all of life's truth's in all its ugliness, people don't like the truth.

"They show the pores in the face of life. The comfortable people want only wax moon faces, poreless, hairless, expressionless. We are living in a time when flowers are trying to live on flowers, instead of growing on good rain and black loam. Even fireworks, for all their prettiness, come from the chemistry of the earth. Yet somehow we think we can grow, feeding on flowers and fireworks, without completing the cycle back to reality."
