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 furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.

For most people read not with their minds, but with their emotions and prejudices. They read into or read out of a piece of writing what they want to. And when they disagree, it is usually not with what the writer says, but with what they imagine he said... People filter what they read through the fine strainer of their feelings and preconceptions, their prejudices and fears.

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.

Lesen ist ein bloßes Surrogat des eigenen Denkens. Man läßt dabei seine Gedanken von dem Andern am Gängelbande führen. [...] Lesen soll man nur dann, wann auch die Quelle der eigenen Gedanken stockt; was auch beim besten Kopfe oft genug der Fall seyn wird. Hingegen die eigenen, urkräftigen Gedanken verscheuchen, um ein Buch zur Hand zu nehmen, ist Sünde wider den heiligen Geist. Man gleicht alsdann Dem, der aus der freien Natur flieht, um ein Herbarium zu besehn, oder um schöne Gegenden im Kupferstiche zu betrachten.

Wann wir lesen, denkt ein Anderer für uns: wir wiederholen bloß den mentalen Prozeß. Es ist damit, wie wenn beim Schreibenlernen der Schüler die vom Lehrer mit Bleistift geschriebenen Züge mit der Feder nachzieht. Demnach ist beim Lesen die Arbeit des Denkens un zum großen Theile abgenommen. Daher die fühlbare Erleichterung, wenn wir von der Beschäftigung mit unseren eigenen Gedanken zum Lesen übergehn. Eben daher kommt es auch, daß wer sehr viel und fast den ganzen Tag liest, dazwischen aber sich in gedankenlosem Zeitvertreibe erholt, die Fähigkeit, selbst zu denken, allmälig verliert, - wie Einer, der immer reitet, zuletzt das Gehn verlernt. Solches aber ist der Fall sehr vieler Gelehrten: sie haben sich dumm gelesen. Denn beständiges, in jedem freien Augenblicke sogleich wieder aufgenommenes Lesen ist noch geisteslähmender, als beständige Handarbeit; da man bei dieser doch den eigenen Gedanken nachhängen kann. Aber wie eine Springfeder durch den anhaltenden Druck eines fremden Körpers ihre Elasticität endlich einbüßt; so der Geist die seine, durch fortwährendes Aufdringen fremder Gedanken. Und wie man durch zu viele Nahrung den Magen verdirbt und dadurch dem ganzen Leibe schadet; so kann man auch durch zu viele Geistesnahrung den Geist überfüllen und ersticken. Denn selbst das Gelesene eignet man sich erst durch späteres Nachdenken darüber an, durch Rumination. Liest man hingegen immerfort, ohne späterhin weiter daran zu denken; so faßt es nic

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

I must confess that I dedicate no inconsiderable portion of my time to other people's thoughts. I dream away my life in others' speculations. I love to lose myself in other men's minds. When I am not walking, I am reading. I cannot sit and think. Books think for me.

Other men are lenses through which we read our own minds.

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

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.

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

I don't see the use of reading the same thing over and over again,' said Phillip. 'That's only a laborious form of idleness.'
But are you under the impression that you have so great a mind that you can understand the most profound writer at a first reading?'
I don't want to understand him, I'm not a critic. I'm not interested in him for his sake but for mine.'
Why do you read then?'
Partly for pleasure, because it's a habit and I'm just as uncomfortable if I don't read as if I don't smoke, and partly to know myself. When I read a book I seem to read it with my eyes only, but now and then I come across a passage, perhaps only a phrase, which has a meaning for me, and it becomes part of me; I've got out of the book all that's any use to me and I can't get anythning more if I read it a dozen times. ...
