Summary
This quote is suggesting that a person who is unable to read relies solely on the information and knowledge that is passed down to them by others. Without the ability to read, they lack the autonomy to seek out different perspectives, facts, or ideas for themselves. Their understanding of the world is limited to the interpretations and biases of those around them, potentially leading to a narrow understanding of the truth. Reading expands one's horizons and enables independent learning, helping individuals form their own opinions and make informed decisions.
