Summary
This quote suggests that it is only possible for someone to demonstrate the reasons and evidence that led them to form a particular opinion. It implies that individuals are limited in their ability to convince others to adopt their viewpoint since they can only provide explanations for their own beliefs, not force others to adopt those same beliefs. The quote emphasizes the importance of personal experience, logical reasoning, and acquiring knowledge to support and justify one's opinion, rather than expecting others to accept it without proper explanation.
