Some people read books but claim to learn nothing new from it.
And that’s okay. There’s nothing wrong with that.
Because often more valuable than the knowledge found in books are the changes to our mindset as a result of having read it.
Books allow us to gain insight, gather perspectives and develop opinions. If it can reinforce the knowledge of what we already know — that’s great. Being able to read a book and realize you already know most of what is read is better than not having read it in the first place.
All that said, here’s the catch:
Do you truly understand the book as well as you believe yourself to?
Our way of looking at the world, or at anything is limited by our current understanding of it. We all have different interpretations and as such, is our current interpretation of the book truly sufficient in saying we’ve learned everything there is to learn from it?
Is it possible that there are other interpretations of the book worth pursuing?
A good book is similar to a good movie in the sense that there’s often so much information to be comprehended, it takes more than once to discover all that we’ve missed.
As C.S. Lewis puts it, “If you have only read a great book once, you have not read it at all.”
