Quote by Bertrand Russell
The fundamental cause of trouble in the world is that the stupid are cocksure while the intelligent are full of doubt.
Summary
This quote implies that ignorance breeds overconfidence, while intelligence prompts self-doubt. It suggests that the lack of knowledge or critical thinking can lead people to be unwaveringly assertive in their beliefs and actions. Meanwhile, those who possess a higher level of intelligence or understanding are more likely to question their own knowledge, resulting in a more cautious and reflective approach. By highlighting this contrast, the quote indirectly suggests that the arrogance and certainty of the ignorant often contribute to the problems and conflicts seen in the world.
