Summary
This quote suggests that the most dangerous aspect of a fanatic is not their passion or obsession, but rather their unwavering belief in their cause. While sincerity is generally considered a virtue, it can become a vice when it blinds individuals to reason and neutrality, leading them to be intolerant and closed-minded. Fanatics are often willing to act on their beliefs without question or consideration for others, making them capable of great harm in the pursuit of their convictions. This quote serves as a warning against the potentially destructive power of unquestioned sincerity.
