This is that which I think great readers are apt to be mistaken in. Those who have read of every thing are thought to understand every thing too; but it is not always so. Reading furnishes the mind only with materials of knowledge; it is thinking makes what we read ours. We are of the ruminating kind, and it is not enough to cram ourselves with a great load of collections; unless we chew them over again, they will not give us strength and nourishment.

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...

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 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.

reading is equivalent to thinking with someone else's head instead of with ones own

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

All the materials of thinking are derived either from our outward senses or from our inward feelings: all that the mind and will do is to mix and combine these materials.

What counts, in the long run, is not what you read; it is what you sift through your own mind; it is the ideas and impressions that are aroused in you by your reading.

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

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.

The constant steaming in of thoughts of others must suppress and confine our own and indeed in the long run paralyze the power of thought… The inclination of most scholars is a kind of fuga vacui ( latin for vacuum suction )from the poverty of their own mind , which forcibly draws in the thoughts of others… It is dangerous to read about a subject before we have thought about it ourselves… When we read, another person thinks for us; merely repeat his mental process. So it comes about that if anybody spends almost the whole day in reading, he gradually loses the capacity for thinking. Experience of the world may be looked upon as a kind of text, to which reflection and knowledge form the commentary. Where there is a great deal of reflection and intellectual knowledge and very little experience , the result is like those books which have on each page two lines of text to forty lines of commentary

If you only read the books that everyone else is reading, you can only think what everyone else is thinking.

I know people who read interminably, book after book, from page to page, and yet I
should not call them 'well-read people'. Of course they 'know' an immense amount; but
their brain seems incapable of assorting and classifying the material which they have
gathered from books. They have not the faculty of distinguishing between what is
useful and useless in a book; so that they may retain the former in their minds and if
possible skip over the latter while reading it, if that be not possible, then — when once
read — throw it overboard as useless ballast. Reading is not an end in itself, but a means
to an end. Its chief purpose is to help towards filling in the framework which is made
up of the talents and capabilities that each individual possesses. Thus each one procures
for himself the implements and materials necessary for the fulfilment of his calling in
life, no matter whether this be the elementary task of earning one's daily bread or a
calling that responds to higher human aspirations. Such is the first purpose of reading.
And the second purpose is to give a general knowledge of the world in which we live.
In both cases, however, the material which one has acquired through reading must not
be stored up in the memory on a plan that corresponds to the successive chapters of the
book; but each little piece of knowledge thus gained must be treated as if it were a little
stone to be inserted into a mosaic, so that it finds its proper place among all the other
pieces and particles that help to form a general world-picture in the brain of the reader.
Otherwise only a confused jumble of chaotic notions will result from all this reading.
That jumble is not merely useless, but it also tends to make the unfortunate possessor of
it conceited. For he seriously considers himself a well-educated person and thinks that
he understands something of life. He believes that he has acquired knowledge, whereas
the truth is that every increase in such 'knowledge' draws him more and mo

Reading without thinking is as nothing, for a book is less important for what it says than for what it makes you think.
