It is quite usual for us to gather pieces of information from various sources, thinking in this way to increase our knowledge. Actually, following this way we end up not knowing anything at all... Instead of gathering knowledge, you should clear your mind. If your mind is clear, true knowledge is already yours.

IF you remember every word in this book, your memory will have recorded about two million pieces of information: the order in your brain will have increased by about two million units. However, while you have been reading the book, you will have converted at least a thousand calories of ordered energy, in the form of food, into disordered energy, in the form of heat that you lose to the air around you by convection and sweat. This will increase the disorder of the universe by about twenty million million million million units - or about ten million million million times the increase in order in your brain - and that's if you remember everything in this book.

Science can be divided into an infinite number of disciplines, and the amount of knowledge that can be pursued in each discipline is limitless. The most critical piece of knowledge, then, is the knowledge of what is essential to learn and what isn’t.

A huge amount of knowledge is accumulated at present. Soon our abilities will be too weak, and our lives too short, to study this knowledge. We have vast treasures of knowledge at our disposal but after we study them, we often do not use them at all. It would be better not to have this burden, this unnecessary knowledge, which we do not really need.

And what good has all your reading done you? Out of all the things you have read, how much has really stayed in your soul, what roots have grown there that will, in a good time, bring forth fruit? Examine your heart carefully. If you compare the whole of what you know with what you don’t know, you will find that your knowledge is like a small stream dried up in the summer heat compared to the ocean of your ignorance. And even granted that you do know a lot, what difference does it make?

Order is not enough. You can’t just be stable, and secure, and unchanging, because there are still vital and important new things to be learned. Nonetheless, chaos can be too much. You can’t long tolerate being swamped and overwhelmed beyond your capacity to cope while you are learning what you still need to know. Thus, you need to place one foot in what you have mastered and understood and the other in what you are currently exploring and mastering. Then you have positioned yourself where the terror of existence is under control and you are secure, but where you are also alert and engaged. That is where there is something new to master and some way that you can be improved. That is where meaning is to be found.

Even if all knowledge could be found in books, where it is mixed in with so many useless things and confusingly heaped in such large volumes, it would take longer to read those books than we have to live in this life and more effort to select the useful things than to find them oneself

"Knowledge is fundamental to all human achievements and progress. It is both the key and the quest that advances mankind. The search for knowledge is what brought men to the moon; but it took knowledge already acquired to make it possible to get there.

How we use the knowledge we gain determines our progress on earth, in space or on the moon. Your library is a storehouse for mind and spirit. Use it well."

[<i>Letters of Note</i>; Troy (MI, USA) Public Library, 1971]

When a man’s knowledge is not in order, the more of it he has, the greater will be his confusion.

What's the point of having great knowledge and keeping them all to yourself?

What's the point of having a library full of books you've already read?

Get your knowledge quickly and then use it. If you can use it you will retain it.

The first was never to accept anything as true that I did not plainly know to be such; that is to say, carefully to avoid hasty judgment and prejudice; and to include nothing more in my judgments than what presented itself to my mind so clearly and so distinctly that I had no occasion to call it in doubt. The second, to divide each of the difficulties I would examine into as many parts as possible and as was required in order better to resolve them. The third, to conduct my thoughts in an orderly fashion, by commencing with those objects that are simplest and easiest to know, in order to ascend little by little, as by degrees, to the knowledge of the most composite things, and by supposing an order even among those things that do not [19] naturally precede one another. And the last, everywhere to make enumerations so complete and reviews so general that I was assured of having omitted nothing.

The richest person in the world - in fact, all the riches in the world - couldn't provide you with anything like the endless, incredible loot available in your local library. You can measure the awareness, the breadth and the wisdom of a civilization, a nation, a people by the priority given to preserving these repositories of all that we are, all that we were, or will be. Our libraries are being eroded alarmingly by inflation. It behooves us - all of us - to stop the rot by the application of that prime preserver - money.

The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.
