I2. Erudition without bullshit, intellect without cowardice, courage without imprudence,
mathematics without nerdiness, scholarship without academia, intelligence without shrewdness,
religiosity without intolerance, elegance without softness, sociality without dependence,
enjoyment without addiction, religion without tolerance, and, above all, nothing without skin in
the game.
I 1. People are much less interested in what you are trying to show them than in what you
are trying to hide.
II 3. A government stating, “We will not stand idle in front of atrocities committed by
[foreign dictator XYZ]” is typically trying to mitigate the guilt for standing idle in front of more
atrocities committed by said XYZ.
II 4. Almost all those caught making a logical fallacy interpret it as a “disagreement.”3
II 5. France took Algeria hoping for a country to eat cassoulet, and instead France is now

wrong.
II 7. If someone is making an effort to ignore you, he is not ignoring you.
II 8. In your prayers substitute “Protect us from evil” with “Protect us from those who
improve things for a salary.”
II 9. Most mistakes get worse when you try to correct them.
II 10. Much of the difference between what is work and what is leisure is branding.
II 11. Never read a book review written by an author whose books you wouldn’t read.
II 12. One of life’s machinations is to make some people both rich and unhappy, that is,
jointly fragile and deprived of hope.
II 13. People don’t like it when you ask them for help; they also feel left out when you
don’t ask them for help.

actually more intelligent than they are.
III 23. Automation makes otherwise pleasant activities turn into “work.”
III 24. For life to be really fun, what you fear should line up with what you desire.

means that you are human.
III 26. It is not possible to have fun when you try.
III 27. Life is about execution rather than purpose.
III 28. The good life—the vita beata—is like reading a Russian novel: It takes two
hundred pages of struggling with the characters before one can start enjoying things. Then the
agitation starts to make sense.
III 29. The ultimate freedom lies in not having to explain why you did something.
III 30. Thinking that all individuals pursue “selfish” interests is equivalent to assuming
that all random variables have zero covariance.
III 31. We need to feel a little bit lost somewhere, physically or intellectually, at least
once a day.5
IV 32. Atheists are just modern versions of religious fundamentalists: both take religion
too literally.
IV 33. Religion isn’t so much about telling man that there is one God as about preventing
man from thinking that he is God.
IV 34. Paganism is decentralized theology.
IV 35. The ancient Mediterranean: before monotheism, people changed and exchanged
rites and gods as we do ethnic foods.
IV 36a. The fewer the Gods the greater the dogma and theological intolerance. So n=0
(“modern” atheists), n= 1 (Sunni purists), n=1-2 (Monophysites), n=3-12 (Greek Orthodoxy), n
flex (Ancient Mediterranean Paganism).

sides.

eats, at no point in time show the pictures of your vacation in Provence or anything that hints at
the differential in means.
V 40. Did you notice that collecting art is to hobby-painting as watching pornography is

V 42. I wonder how many people would seek excessive wealth if it did not carry a
measure of status with it.
V 43. In the days of Suetonius, 60 percent of prominent educators (grammarians) were
slaves. Today the ratio is 97.1 percent, and growing.
V 44. It is good to not feel envy; but better to neither envy nor be envied.
V 45. Success in all endeavors requires the absence of specific qualities. 1) To succeed in
crime requires absence of empathy, 2) To succeed in banking you need absence of shame at
hiding risks, 3) To succeed in school requires absence of common sense, 4) To succeed in
economics requires absence of understanding of probability, risk, second-order effects, or about
anything, 5) To succeed in journalism requires an inability to think about matters that have even
an infinitesimally small chance of being relevant next January, 6) But to succeed in life requires
a total inability to do anything that makes you uncomfortable when you look at yourself in the
mirror.
V 46. The alpha person at a gathering of “high status” persons is often, detectably, the
waiter.
V 47. The natural benefit of cellphones, laptops, and other indispensable modern items is
the joy one gets finding the object after losing it. Lose your wallet full of credit cards and you
will have a chance to have a great day.
V 48. There is no clearer sign of failure than a middle-aged man boasting of his
performance in college.
V 49. What we commonly call “success” (rewards, status, recognition, some new metric)
is a consolation prize for those who are both unhappy and not good at what they do.7
V 50. You can tell how poor someone feels by the number of times he references
“money” in his conversation.
V 51. You will never know for sure if someone is an asshole until he becomes rich.
V 52. Studying the work and intellectual habits of a “genius” to learn from him is like
studying the garb of a chef to emulate his cooking.
V 53. To figure out how well you will do ten years from now relative to someone else,
count your enemies, count his, and square the ratio.

those who have never pondered.
VI 57. Never get into a business partnership with a retired lawyer unless he has another
hobby.
VI 58. Never show a risk number, even if it is right.
VI 59. People tend to whisper when they say the truth and raise their voice when they lie.
VI 60. The problem with academics is that they really think nonacademics find them
more intelligent than themselves.
VI 61. The rational heuristic is to avoid any market commentary from anyone who has to
work for a living. [DUPL?]

VI 63. Universities have been progressing from providing scholarship for a small fee into
selling degrees at a large cost.

money.
VI 65. The fact that people in countries with cold weather tend to be harder working,
richer, less relaxed, less amicable, less tolerant of idleness, more (over)organized and more
harried than those in hotter climates should make us wonder whether wealth is mere
indemnification, and motivation is just overcompensation for not having a real life.
VII 66. A good book gets better on the second reading. A great book on the third. Any
book not worth rereading isn’t worth reading.
VII 67. A heuristic on whether you have control of your life: can you take naps?
VII 68. Fasting: every human should learn to read, write, respect the weak, take risks in
voicing disrespect for the powerful when warranted, and fast.
VII 69b. In summary, modernity replaced process by result and the relational by the
transactional.
VII 69. High Modernity: routine in place of physical effort, physical effort in place of
mental expenditure, and mental expenditure in place of mental clarity.
VII 70. In real life exams, someone gives you an answer and you have to find the best
corresponding questions.
VII 71. It used to take seven years to figure out if a book is a book or journalism between
covers. Now all one needs is wait two years. Soon, a few months.
VII 72. Life is about early detection of the reversal point beyond which your own
belongings (say, a house, country house, car, or business) start owning you.9
VII 73. One of the shortest books I’ve ever read had 745 pages.
VII 74. Real life (vita beata) is when your choices correspond to your duties.
VII 75. Some ideas are born as you write then down, others become dead.
VII 76. The longest book I’ve ever read was 205 pages. [MOVE TO AFTER VII 73]

on balance.
VII 78. I fail to see the difference between extreme wealth and overdose.
VII 79. It is a curse to have ideas that people understand only when it is too late.
VII 80. The most important aspect of fasting is that you feel deep, undirected gratitude
when you break the fast.
VIII 81. A risk you run when you write a book calling journalists BS vendors is that all
your reviewers will be BS vendors.
VIII 82. A writer told me, “I didn’t get anything done today.” Answer: try to do nothing.
The best way to have only good days is to not aim at getting anything done. Actually almost

smaller than that of the previous one.
VIII 84. I want to write books that only those who read them claim they did.
VIII 85. I was told to write medium-sized books. Yet of the two most successful French
novels in history, one is very short (Le Petit Prince, 80 pages), other extra long (Proust’s
Recherche, 3,200 pages), following the statistical arcsine law.10
VIII 86. I wonder why newssuckers don’t realize that if news had the slightest predictive
and nonanecdotal value journalists would be monstrously rich. And if journalists were really not
interested in money they would be writing literary essays.
VIII 87. If the professor is not capable of giving a class without preparation, don’t attend.
People should only teach what they have learned organically, through experience and curiosity . .

is anecdote.

illusion.

fiercely motivated actors.

life.

we can control), not equality in outcome.
X 100. Just as statisticians understand the risks of roulette sequences better than
carpenters, probabilists understand systemic ecological risks better than biologists.

slickness in form make absence of substance nauseating.
XI 102. Studying neurobiology to understand humans is like studying ink to understand
literature.

also are about the only animal with a sense of cruelty.

trouble.

number of pre-rich and an almost as large one of post-rich.
XII 114. I am rather fed up with those who tell me to be nice and try to convince
charlatans. The FBI didn’t “try to convince” the Mafia to abandon its activities.
XII 115. It is a great compliment for an honest person to be mistaken for a crook by a
crook.

in the case of, say, medication, wouldn’t contingently use.13
XII 121. Never call someone an imbecile (or a fucking idiot) unless he causes harm to
others/system; there must be a moral dimension to insults.
XII 122. Never take an advice from a salesman, or any advice that benefits the advice
giver.
XII 123. People reveal much more about themselves while lying than when they tell the
truth.
XII 124. Something shoddy: citizenship of convenience, holding the passport of a country
for ease of travel/tax without committing to its community.
XII 125. Supposedly, if you are uncompromising or intolerant with BS you lose friends.
But you will also make friends, better friends.
XII 126. The bottom half has typically been screwed by the middle class. That’s the
entire story of Rome.
XII 127. Trust those who are greedy for money a thousand times more than those who are
greedy for credentials.
XII 128. Trust those who trust you and distrust those who are suspicious of others.
XII 129. Virtue is when the income you wish to show the tax agency exceeds what you
wish to show your neighbor.
XII 130. Distributive justice isn’t taking from a risk taker who earned honorably, it is
keeping his probability of losing it very high.
XII 131. Soldiers are more loyal to their comrades (and willing to die for them) than to
their country. Academics are more loyal to their peers than to truth.

for simplicity.
XIII142. For a free person, the optimal—most opportunistic—route between two points
should never be the shortest one.
XIV 143. I recently had a meal in a fancy restaurant with complicated dishes with fancy
names ($125 per person), then enjoyed a pizza afterward, straight out of the oven, $7.95. I
wonder why the pizza isn’t twenty times the price of the complicated dish, since I’d rather have
the former—at any price—over the latter.15
XIV 144. Just as eating cow meat doesn’t turn you into a cow, studying philosophy
doesn’t make you wiser.
XIV 145. Mistakes detected by copy editors are not likely to be noticed by readers, and

transported by trucks.

standing outside all hierarchies.

XIX 152. If you are only bad-mouthed by people who prefer your company over those of

need more men in academic philosophy.
XIX 157. The first, and hardest, step to wisdom: avert the standard assumption that
people know what they want.
XIX 158. To be a person of virtue you need to be boringly virtuous in every single small
action. To be a person of honor all you need is to be honorable in a few important things (risk
your life or career or reputation for a just cause, say, or live up to your word when nobody else
has the guts to do so).
XIX 159. Virtue is sequence of small acts of omission. Honor and grandeur can be a
single gutsy, momentous, and self-sacrificial act of commission.

people and the smallest number of academics to attend my funeral
XIX 161. When you cite some old wisdom-style quote and add “important truth,” “to
remember,” or “something to live by,” you are not doing so because it is good, only because it is
inapplicable. Had it been both good and applicable you would not have had to cite it. Wisdom
that is hard to execute isn’t really wisdom.

from people you wouldn’t hire.

XIX 164. Magnificence is defined by the intersection of reluctant praise by your enemies

XV 167. In a conflict, the middle ground is least likely to be correct.
XV 168. In the medical and social domains, treatment should never be equivalent to
silencing symptoms.
XV 169. Those who violate a rule in a logically self-consistent system can only do well if
they violate at least one additional logical rule.
XVII 170. It is perplexing but amusing to observe people getting extremely excited about
things you don’t care about; it is sinister to watch them ignore things you believe are
fundamental.

it.

that are bankrupt and hide it, those that are bankrupt and don’t know it.
XVIII 188. A trader listened to the firm’s “chief” economist’s predictions about gold,
then lost a bundle. The trader was asked to leave the firm. He then angrily asked the boss who
was firing him, “Why do you fire me alone, not the economist? He too is responsible for the
loss.” The boss: “You idiot, we are not firing you for losing money—we are firing you for
listening to the economist.”
XVIII 189. Economics is about making simple things more complicated, mathematics
about making complicated things simpler.

XX 196. A happier world is one in which everyone realizes that 1) it is not what you tell
people, it is how you say it that makes them feel bad; 2) it is not what you do to them but how
you make them look that gets them angry; 3) they should be the ones putting themselves in a
specific category.
XX 197. Complaints don’t deliver complaints, they mostly reveal your weakness.
XX 198.a Knowing stuff others don't know is most effective when others don't know you

your beard is white, skip the why, just say what should be done.20

otherwise.

self-owned.

who never had real world experience.

you.21
XXI 211. Used skillfully, a compliment will be much more offensive than any
disparagement.
XXI 212. What counts is not what people say about you, it is how much energy they
spend in saying it.
XXI 213. When people call you intelligent it is almost always because they agree with
you. Otherwise they just call you arrogant.
XXI214. We often benefit from harm done to us by others, almost never from selfinflicted injuries.
XXII 215. The only problem with the last laugh is that the winner has to laugh alone.
