Fanaticism is always a sign of repressed doubt.
fanaticismquotes
It is not growing fanaticism, but growing democracy, that causes my troubles. Did you ever read the life of Averroes? He was protected by kings, but hated by the mob, which was fanatical. In the end, the mob won. Free thought has always been a perquisite of aristocracy.

This false epistemology, however, has also led to disastrous consequences. The theory that truth is manifest—that it is there for everyone to see, if only he wants to see it — this theory is the basis of almost every kind of fanaticism. For only the most depraved wickedness can refuse to see the manifest truth; only those who have reason to fear truth conspire to suppress it.
