"As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value than a much smaller amount if you have not thought it over for yourself"

This quote indicates that having a big quantity of knowledge is not as important as having a smaller sized quantity that you have actually personally understood and arranged. It is very important to think critically about the information you have and organize it in a significant method, instead of just accumulating a lot of info without fully comprehending it. A smaller quantity of well-organized understanding will be better than a larger quantity of disorganized details.
