Quotes

Aphorisms (1765-1799)

Notebook A (1765-1770)

 * One might call habit a moral friction: something that prevents the mind from gliding over things but connects it with them and makes it hard for it to free itself from them.
 * A 10


 * It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people's attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.
 * A 11


 * Food probably has a very great influence on the condition of men. Wine exercises a more visible influence, food does it more slowly but perhaps just as surely. Who knows if a well-prepared soup was not responsible for the pneumatic pump or a poor one for a war?
 * A 14


 * It is we who are the measure of what is strange and miraculous: if we sought a universal measure the strange and miraculous would not occur and all things would be equal.
 * A 26


 * Cautiousness in judgment is nowadays to be recommended to each and every one: if we gained only one incontestable truth every ten years from each of our philosophical writers the harvest we reaped would be sufficient. … To grow wiser means to learn to know better and better the faults to which this instrument with which we feel and judge can be subject.
 * A 38


 * Prejudices are so to speak the mechanical instincts of men: through their prejudices they do without any effort many things they would find too difficult to think through to the point of resolving to do them.
 * A 58

Notebook B (1768-1771)



 * We can see nothing whatever of the soul unless it is visible in the expression of the countenance; one might call the faces at a large assembly of people a history of the human soul written in a kind of Chinese ideograms.
 * B 11


 * Every man has his moral backside which he refrains from showing unless he has to and keeps covered as long as possible with the trousers of decorum.

 * As quoted in Der Witz und seine Beziehung zum Unbewussten [Jokes and Their Relation to the Unconscious] (1905) by Sigmund Freud, as translated by James Strachey (1960), p. 100


 * There are two ways of extending life: firstly by moving the two points "born" and "died" farther away from one another... The other method is to go more slowly and leave the two points wherever God wills they should be, and this method is for the philosophers.
 * B 22


 * I have written a good number of drafts and small reflections. They are not waiting for the last touch but for the sunlight to wake them up.

 * As the few adepts in such things well know, universal morality is to be found in little everyday penny-events just as much as in great ones. There is so much goodness and ingenuity in a raindrop that an apothecary wouldn't let it go for less than half-a-crown.
 * B 33


 * Here take back the stuff that I am, nature, knead it back into the dough of being, make of me a bush, a cloud, whatever you will, even a man, only no longer make me me.
 * B 37 "Speech of a suicide composed shortly before the act."


 * People often become scholars for the same reason they become soldiers: simply because they are unfit for any other station. Their right hand has to earn them a livelihood; one might say they lie down like bears in winter and seek sustenance from their paws.
 * B 41


 * If an angel were ever to tell us anything of his philosophy I believe many propositions would sound like 2 times 2 equals 13.
 * B 44


 * We often have need of a profound philosophy to restore to our feelings their original state of innocence, to find our way out of the rubble of things alien to us, to begin to feel for ourselves and to speak ourselves, and I might almost say to exist ourselves. Even if my philosophy does not extend to discovering anything new, it does nevertheless possess the courage to regard as questionable what has long been thought true.
 * B 49


 * What concerns me alone I only think, what concerns my friends I tell them, what can be of interest to only a limited public I write, and what the world ought to know is printed...
 * B 52

 * C 23


 * Erudition can produce foliage without bearing fruit.
 * C 26


 * Even truth needs to be clad in new garments if it is to appeal to a new age.
 * C 33


 * Once the good man was dead, one wore his hat and another his sword as he had worn them, a third had himself barbered as he had, a fourth walked as he did, but the honest man that he was — nobody any longer wanted to be that.
 * C 36


 * The pleasures of the imagination are as it were only drawings and models which are played with by poor people who cannot afford the real thing.
 * C 38


 * If people should ever start to do only what is necessary millions would die of hunger.

Notebook E (1775 - 1776)

 * A book is a mirror: if an ape looks into it an apostle is hardly likely to look out. We have no words for speaking of wisdom to the stupid. He who understands the wise is wise already.
 * E 49
 * Variant translations of first portion: A book is a mirror: If an ape peers into it, you can't expect an apostle to look out.
 * A book is a mirror: If an ass peers into it, you can't expect an apostle to look out. — this has actually been the most commonly cited form, but it is based on either a loose non-literal translation or a mistranslation of the German original: Ein Buch ist Spiegel, aus dem kein Apostel herausgucken kann, wenn ein Affe hineinguckt.


 * As I take up my pen I feel myself so full, so equal to my subject, and see my book so clearly before me in embryo, I would almost like to try to say it all in a single word.

 * The great rule: If the little bit you have is nothing special in itself, at least find a way of saying it that is a little bit special.
 * E 55

 * E 59
 * Variant translation: There are people who think that everything one does with a serious face is sensible...


 * Do we write books so that they shall merely be read? Don't we also write them for employment in the household? For one that is read from start to finish, thousands are leafed through, other thousands lie motionless, others are jammed against mouseholes, thrown at rats, others are stood on, sat on, drummed on, have gingerbread baked on them or are used to light pipes.
 * E 65


 * Good taste is either that which agrees with my taste or that which subjects itself to the rule of reason. From this we can see how useful it is to employ reason in seeking out the laws of taste.

Notebook J (1789)



 * A schoolteacher or professor cannot educate individuals, he educates only species.
 * J 10


 * A great speech is easy to learn by heart and a great poem even easier. How hard it would be to memorize as many words linked together senselessly, or a speech in a foreign tongue! Sense and understanding thus come to the aid of memory. Sense is order and order is in the last resort conformity with our nature. When we speak rationally we are only speaking in accordance with the nature of our being. That is why we devise genera and species in the case of plants and animals. The hypotheses we make belong here too: we are obliged to have them because otherwise we would unable to retain things... The question is, however, whether everything is legible to us. Certainly experiment and reflection enable us to introduce a significance into what is not legible, either to us or at all: thus we see faces or landscapes in the sand, though they are certainly not there. The introducion of symmetries belongs here too, silhouettes in inkblots, etc. Likewise the gradation we establish in the order of creatures: all this is not in the things but in us. In general we cannot remember too often that when we observe nature, and especially the ordering of nature, it is always ourselves alone we are observing.
 * J 65

 * One cannot demand of a scholar that he show himself a scholar everywhere in society, but the whole tenor of his behavior must none the less betray the thinker, he must always be instructive, his way of judging a thing must even in the smallest matters be such that people can see what it will amount to when, quietly and self-collected, he puts this power to scholarly use.
 * J 85


 * The most perfect ape cannot draw an ape; only man can do that; but, likewise, only man regards the ability to do this as a sign of superiority.
 * J 115


 * It is a question whether, when we break a murderer on the wheel, we do not fall into the error a child makes when it hits the chair it has bumped into.

 * It is said that truth comes from the mouths of fools and children: I wish every good mind which feels an inclination for satire would reflect that the finest satirist always has something of both in him.

 * K 39
 * Variant translation: Before we blame we should first see whether we cannot excuse.

 * K 48


 * One is rarely an impulsive innovator after the age of sixty, but one can still be a very fine orderly and inventive thinker. One rarely procreates children at that age, but one is all the more skilled at educating those who have already been procreated, and education is procreation of another kind.
 * K 51

 * K 52


 * First we have to believe, and then we believe.

 * K 72

Notebook L (1793-1796)

 * If this is philosophy it is at any rate a philosophy that is not in its right mind.
 * L 23


 * Those who have racked their brains to discover new proofs have perhaps been induced to do so by a compulsion they could not quite explain to themselves. Instead of giving us their new proofs they should have explained to us the motivation that constrained them to search for them.
 * L24


 * The "second sight" possessed by the Highlanders in Scotland is actually a foreknowledge of future events. I believe they possess this gift because they don't wear trousers... That is also why in all countries women are more prone to utter prophecies.

Quotes about Lichtenberg

 * Sorted alphabetically by author or source




 * Perhaps he was even more remarkable as a psychologist than as a physicist.
 * Sigmund Freud, in an open letter to Albert Einstein, "Why War" (1933), as translated in Classical Readings in Culture and Civilization (1998) edited by Stephen Mennell and John F. Rundell


 * We may use Lichtenberg’s writings as the most wonderful dowsing rod: wherever he makes a joke, there a problem lies hidden.
 * Johann Wolfgang von Goethe, as quoted in Lives of the Mind: The Use and Abuse of Intelligence from Hegel to Wodehouse (2002), p. 316


 * God created man in His own image, and in requital man created God in his, says Lichtenberg, and it is true that a man’s conception of God is essentially determined by the kind of man he is. So it is that I conceive of God as one who approves in a calculated vigilance, I believe that he approves of intrigues, and what I have read in the sacred books of the Old Testament is not of a sort to dishearten me. The Old Testament furnishes examples abundantly of a shrewdness which is nevertheless well pleasing to God, and that at a later period Christ said to His disciples, “These things I said not unto you from the beginning … I have yet many things to say unto you, but ye cannot bear them now” – so here is a teleological suspension of the ethical rule of telling the whole truth.
 * Soren Kierkegaard, in Quidam’s Diary from Stages on Life’s Way (1845), Lowrie translation (1967), p. 217-218


 * He is not a household name. He is something rarer: a name savored by household names. Goethe, who corresponded with Lichtenberg, admired him greatly (even though Lichtenberg disputed his theory of color).
 * Roger Kimball, in Lives of the Mind: The Use and Abuse of Intelligence from Hegel to Wodehouse (2002), p. 316


 * Lichtenberg digs deeper than anyone... but he does not come up again. Only he hears him who digs deep himself.

 * Variant translations:
 * Lichtenberg goes deeper than any other, but he does not come up again. He speaks under the Earth. He is only heard by those who themselves dig deep.
 * As quoted in The Last Days of Mankind : Karl Kraus and his Vienna (1967) by Frank Field, p. 196
 * Lichtenberg digs deeper than anyone... He speaks from the subterranean depths. Only he who himself digs deep hears him.
 * As quoted in Lives of the Mind: The Use and Abuse of Intelligence from Hegel to Wodehouse (2002) by Roger Kimball, p. 316
