"The oldest books are only just out to those who have not read them"

This quote by Samuel Butler is a pointer that knowledge is not limited. Even if a book is old, it can still be brand-new to someone who has not read it. It is a tip that there is constantly something new to learn, no matter how much we believe we understand. It is also a tip that we should never stop learning and exploring. We need to never assume that we know everything, because there is constantly something new to discover. This quote motivates us to keep an open mind and to never ever stop learning. It is a reminder that understanding is unlimited and that we ought to never ever stop seeking it.
