“The whole problem with the world is that fools and fanatics are always so certain of themselves.”
— Bertrand Russell
Simplified Meaning:
Sometimes, people who don't know much or are extreme in their beliefs act like they know everything. They speak loudly and confidently, often thinking they're right no matter what. For example, imagine someone who argues very strongly about a topic they don't fully understand, like a person insisting they know how to fix a car without ever having fixed one before. This kind of behavior can cause problems because their strong opinions can mislead others or create conflicts. On the other hand, knowledgeable and thoughtful people might doubt themselves and think carefully before speaking, so their voices are not heard as much. Learning to listen more to thoughtful people and questioning confident but uninformed statements can help avoid mistakes and misunderstandings.
