Reading is to the mind, what exercise is to the body. As by the one, health is preserved, strengthened, and invigorated: by the other, virtue (which is the health of the mind) is kept alive, cherished, and confirmed.

Reading to the mind is what exercise is to the body.

In its silence, a book is a challenge: it can't lull you with surging music or deafen you with screeching laugh tracks or fire gunshots in your living room; you have to listen to it in your head. A book won't move your eyes for you the way images on a screen do. It won't move your mind unless you give it your mind, or your heart unless you put your heart in it ... To read a story well is to follow it, to act it, to feel it, to become it — everything short of writing it, in fact. Reading is not interactive with a set of rules or options, as games are; reading is actual collaboration with the writer's mind. No wonder not everyone is up to it.

..reading a book doesn’t mean just turning the pages. It means thinking about it, identifying parts that you want to go back to, asking how to place it in a broader context, pursuing the ideas. There’s no point in reading a book if you let it pass before your eyes and then forget about it ten minutes later. Reading a book is an intellectual exercise, which stimulates thought, questions, imagination.

Books are to be call’d for, and supplied, on the assumption that the process of reading is nor a half-sleep, but, in highest sense, an exercise, a gymnast’s struggle; that the reader is to do something for himself, must be on the alert, must himself or herself construct indeed the poem, argument, history, metaphysical essay — the text furnishing the hints, the clue, the start or frame-work. Not the book needs so much to be the complete thing, but the reader of the book does. That were to make a nation of supple and athletic minds well-train’d, intuitive, used to depend on themselves, not on a few coteries of writers.

When we read, another person thinks for us: we merely repeat his mental process. In learning to write, the pupil goes over with his pen what the teacher has outlined in pencil: so in reading; the greater part of the work of thought is already done for us. This is why it relieves us to take up a book after being occupied with our own thoughts. And in reading, the mind is, in fact, only the playground of another’s thoughts. So it comes about that if anyone spends almost the whole day in reading, and by way of relaxation devotes the intervals to some thoughtless pastime, he gradually loses the capacity for thinking; just as the man who always rides, at last forgets how to walk. This is the case with many learned persons: they have read themselves stupid.

A mind needs books like a sword needs a whetstone, if it is to keep its edge. That is why I read so much.

Reading is merely a surrogate for thinking for yourself; it means letting someone else direct your thoughts. Many books, moreover, serve merely to show how many ways there are of being wrong, and how far astray you yourself would go if you followed their guidance. You should read only when your own thoughts dry up, which will of course happen frequently enough even to the best heads; but to banish your own thoughts so as to take up a book is a sin against the holy ghost; it is like deserting untrammeled nature to look at a herbarium or engravings of landscapes.

Curiously enough, one cannot read a book: one can only reread it. A good reader, a major reader, an active and creative reader is a rereader. And I shall tell you why. When we read a book for the first time the very process of laboriously moving our eyes from left to right, line after line, page after page, this complicated physical work upon the book, the very process of learning in terms of space and time what the book is about, this stands between us and artistic appreciation. When we look at a painting we do not have to move our eyes in a special way even if, as in a book, the picture contains elements of depth and development. The element of time does not really enter in a first contact with a painting. In reading a book, we must have time to acquaint ourselves with it. We have no physical organ (as we have the eye in regard to a painting) that takes in the whole picture and then can enjoy its details. But at a second, or third, or fourth reading we do, in a sense, behave towards a book as we do towards a painting. However, let us not confuse the physical eye, that monstrous masterpiece of evolution, with the mind, an even more monstrous achievement. A book, no matter what it is — a work of fiction or a work of science (the boundary line between the two is not as clear as is generally believed) — a book of fiction appeals first of all to the mind. The mind, the brain, the top of the tingling spine, is, or should be, the only instrument used upon a book.

Books are not only the arbitrary sum of our dreams, and our memory. They also give us the model of self-transcendence. Some people think of reading only as a kind of escape: an escape from the “real” everyday world to an imaginary world, the world of books. Books are much more. They are a way of being fully human.

"How are you coming with your home library? Do you need some good ammunition on why it's so important to read? The last time I checked the statistics...I think they indicated that only four percent of the adults in this country have bought a book within the past year. That's dangerous. It's extremely important that we keep ourselves in the top five or six percent.
In one of the Monthly Letters from the Royal Bank of Canada it was pointed out that reading good books is not something to be indulged in as a luxury. It is a necessity for anyone who intends to give his life and work a touch of quality. The most real wealth is not what we put into our piggy banks but what we develop in our heads. Books instruct us without anger, threats and harsh discipline. They do not sneer at our ignorance or grumble at our mistakes. They ask only that we spend some time in the company of greatness so that we may absorb some of its attributes.

You do not read a book for the book's sake, but for your own.

You may read because in your high-pressure life, studded with problems and emergencies, you need periods of relief and yet recognize that peace of mind does not mean numbness of mind.

You may read because you never had an opportunity to go to college, and books give you a chance to get something you missed. You may read because your job is routine, and books give you a feeling of depth in life.

You may read because you did go to college.

You may read because you see social, economic and philosophical problems which need solution, and you believe that the best thinking of all past ages may be useful in your age, too.

You may read because you are tired of the shallowness of contemporary life, bored by the current conversational commonplaces, and wearied of shop talk and gossip about people.

Whatever your dominant personal reason, you will find that reading gives knowledge, creative power, satisfaction and relaxation. It cultivates your mind by calling its faculties into exercise.

At the end of the day, some authors will endure and most, including some very good ones, will not. Why do I think reading is important? It is such an effective medium between mind and mind. We think largely in words. A medium made only of words doesn't impose the barrier of any other medium. It is naked and unprotected communication. That's how you get pregnant. May you always be so.

When we read, another person thinks for us: we merely repeat his mental process. It is the same as the pupil, in learning to write, following with his pen the lines that have been pencilled by the teacher. Accordingly, in reading, the work of thinking is, for the greater part, done for us. This is why we are consciously relieved when we turn to reading after being occupied with our own thoughts. But, in reading, our head is, however, really only the arena of some one else's thoughts. And so it happens that the person who reads a great deal — that is to say, almost the whole day, and recreates himself by spending the intervals in thoughtless diversion, gradually loses the ability to think for himself; just as a man who is always riding at last forgets how to walk. Such, however, is the case with many men of learning: they have read themselves stupid. For to read in every spare moment, and to read constantly, is more paralysing to the mind than constant manual work...
