"私が今までに知り合った中で最も賢い人は、読むことも書くこともできませんでした。"

Simplified Meaning:

Sometimes, people who can't read or write still have a lot of valuable knowledge and wisdom. This can come from their life experiences and their observations of the world around them. For example, think of a farmer who has worked the land for many years. He might not be able to read books about farming, but he understands the weather, the soil, and the best times to plant and harvest. His knowledge is practical, learned from doing the work every day. This idea teaches us to recognize different types of intelligence beyond just academic skills. It reminds us to listen and learn from everyone's experiences because wisdom doesn’t only come from formal education. So, when faced with a problem, seek advice from those who have lived through similar situations, even if they haven't studied it in school. This way, we can gain a deeper understanding of the world around us.
