“The art of writing books is not yet invented. But it is at the point of being invented.”

Fragment No. 114
Blüthenstaub (1798)
Context: The art of writing books is not yet invented. But it is at the point of being invented. Fragments of this nature are literary seeds. There may be many an infertile grain among them: nevertheless, if only some come up!

“A book must be the axe for the frozen sea within us.”

Variant translations:
If the book we are reading does not wake us, as with a fist hammering on our skulls, then why do we read it? Good God, we also would be happy if we had no books and such books that make us happy we could, if need be, write ourselves. What we must have are those books that come on us like ill fortune, like the death of one we love better than ourselves, like suicide. A book must be an ice axe to break the sea frozen inside us.
What we need are books that hit us like a most painful misfortune, like the death of someone we loved more than we love ourselves, that make us feel as though we had been banished to the woods, far from any human presence, like a suicide. A book must be the ax for the frozen sea within us.
A book should be an ice-axe to break the frozen sea within us.
A book must be an ice-axe to break the seas frozen inside our soul.
A book should serve as the ax for the frozen sea within us.
Variant: A book must be the axe for the frozen sea inside us.
Context: I think we ought to read only the kind of books that wound and stab us. If the book we are reading doesn't wake us up with a blow on the head, what are we reading it for?... we need the books that affect us like a disaster, that grieve us deeply, like the death of someone we loved more than ourselves, like being banished into forests far from everyone, like a suicide. A book must be the axe for the frozen sea inside us.

“Books are fatal: they are the curse of the human race. Nine- tenths of existing books are nonsense, and the clever books are the refutation of that nonsense. The greatest misfortune that ever befell man was the invention of printing.”

Benjamin Disraeli (1804–1881) British Conservative politician, writer, aristocrat and Prime Minister

“It is not in the books of the Philosophers, but in the religious symbolism of the Ancients, that we must look for the footprints of Science, and re-discover the Mysteries of Knowledge.”

Source: Morals and Dogma of the Ancient and Accepted Scottish Rite of Freemasonry (1871), Ch. XXXII : Sublime Prince of the Royal Secret
Context: Science has its nights and its dawns, because it gives the intellectual world a life which has its regulated movements and its progressive phases. It is with Truths, as with the luminous rays: nothing of what is concealed is lost; but also, nothing of what is discovered is absolutely new. God has been pleased to give to Science, which is the reflection of His Glory, the Seal of His Eternity.
It is not in the books of the Philosophers, but in the religious symbolism of the Ancients, that we must look for the footprints of Science, and re-discover the Mysteries of Knowledge.

“Saying the Bible is not a book about science is like saying a cookbook is not a book about chemistry.”

Pursuance of truth requires consideration of a creator. If you define science to exclude the possibility of a creator, it isn’t a pursuance of truth.
The universe as accepted by science in terms of size and age is not big enough or old enough to explain evolution.

“They were doing their best to live like people invented in story books.”

Breakfast of Champions (1973)
Context: I thought Beatrice Keedsler had joined hands with other old-fashioned storytellers to make people believe that life had leading characters, minor characters, significant details, insignificant details, that it had lessons to be learned, tests to be passed, and a beginning, a middle, and an end.
As I approached my fiftieth birthday, I had become more and more enraged and mystified by the idiot decisions made by my countrymen. And then I had come suddenly to pity them, for I understood how innocent and natural it was for them to behave so abominably, and with such abominable results: They were doing their best to live like people invented in story books. This was the reason Americans shot each other so often: It was a convenient literary device for ending short stories and books.
Why were so many Americans treated by their government as though their lives were as disposable as paper facial tissues? Because that was the way authors customarily treated bit-part players in their madeup tales.
And so on.
Once I understood what was making America such a dangerous, unhappy nation of people who had nothing to do with real life, I resolved to shun storytelling. I would write about life. Every person would be exactly as important as any other. All facts would also be given equal weightiness. Nothing would be left out. Let others bring order to chaos. I would bring chaos to order, instead, which I think I have done.
If all writers would do that, then perhaps citizens not in the literary trades will understand that there is no order in the world around us, that we must adapt ourselves to the requirements of chaos instead.
It is hard to adapt to chaos, but it can be done. I am living proof of that: It can be done.
