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

Reading is to the mind what exercise is to the body and prayer is to the soul. We become the books we read.

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.

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. 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.

Reading is the work of the alert mind, is demanding, and under ideal conditions produces finally a sort of ecstasy.

..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.

To read well, that is, to read true books in a true spirit, is a noble exercise, and one that will tax the reader more than any exercise which the customs of the day esteem. It requires a training such as the athletes underwent, the steady intention almost of the whole life to this object. Books must be read as deliberately and reservedly as they were written.

[T]o read was precisely to enter another world, which was not the reader's own, and come back refreshed, ready to bear with equanimity the injustices and frustrations of this one. Reading was balm, amusement — not incitement.

IMPORTANT Book reading is a solitary and sedentary pursuit, and those who do are cautioned that a book should be used as an integral part of a well-rounded life, including a daily regimen of rigorous physical exercise, rewarding personal relationships, and sensible low-fat diet. A book should not be used a as a substitute or an excuse.

When reading you have the opportunity to pause for thought & spark your imagination. It develops intellect. Nothing more threatening to a politician than a well read working class.

The reader must come armed , in a serious state of intellectual readiness. This is not easy because he comes to the text alone. In reading, one's responses are isolated, one'sintellect thrown back on its own resourses. To be confronted by the cold abstractions of printed sentences is to look upon language bare, without the assistance of either beauty or community. Thus, reading is by its nature a serious business. It is also, of course, an essentially rational activity.

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...

Let us assume that entertainment is the sole end of reading; even so I think you would hold that no mental employment is so broadening to the sympathies or so enlightening to the understanding. Other pursuits belong not to all times, all ages, all conditions; but this gives stimulus to our youth and diversion to our old age; this adds a charm to success, and offers a haven of consolation to failure. Through the night-watches, on all our journeyings, and in our hours of ease, it is our unfailing companion.
