“Why does the truth now lead to hatred...”
Why does the truth now lead to hatred, causing people to become enemies of those who share it? A happy life is cherished, and that happiness comes from embracing the truth. Perhaps it's because people love the truth only when it aligns with what they already cherish. They want to believe they are right and resist being shown otherwise. This is why they hate the truth—it threatens what they love more than the truth itself. They appreciate the truth when it enlightens them but despise it when it points out their faults. They want to avoid being deceived, yet they often deceive themselves. They love the truth when it reveals something positive, but they hate it when it exposes their flaws.
— St. Augustine, Confessions, Book X, Chapter XXIII
