Why Truth Generates Hatred - St. Augustine

“Why, then, does truth generate hatred, and why does thy servant who preaches the truth come to be an enemy to them who also love the happy life, which is nothing else than joy in the truth—unless it be that truth is loved in such a way that those who love something else besides her wish that to be the truth which they do love. Since they are unwilling to be deceived, they are unwilling to be convinced that they have been deceived. Therefore, they hate the truth for the sake of whatever it is that they love in place of the truth. They love truth when she shines on them; and hate her when she rebukes them.”

St. Augustine of Hippo, Confessions, Book 10, Chapter 23
