Book review: The Finders, by Jeffery A Martin.

This book is about the states of mind that Martin labels Fundamental Wellbeing.

These seem to be what people seek through meditation, but Martin carefully avoids focusing on Buddhism, and says that other spiritual approaches produce similar states of mind.

Martin approaches the subject as if he were an anthropologist. I expect that’s about as rigorous as we should hope for on many of the phenomena that he studies.

The most important change associated with Fundamental Wellbeing involves the weakening or disappearance of the Narrative-Self (i.e. the voice that seems to be the center of attention in most human minds).

I’ve experienced a weak version of that. Through a combination of meditation and CFAR ideas (and maybe The Mating Mind, which helped me think of the Narrative-Self as more of a press secretary than as a leader), I’ve substantially reduced the importance that my brain attaches to my Narrative-Self, and that has significantly reduced how much I’m bothered by negative stimuli.

Some more “advanced” versions of Fundamental Wellbeing also involve a loss of “self” – something along the lines of being one with the universe, or having no central locus or vantage point from which to observe the world. I don’t understand this very well. Martin suggests an analogy which describes this feeling as “zoomed-out”, i.e. the opposite extreme from Hyperfocus or a state of Flow. I guess that gives me enough hints to say that I haven’t experienced anything that’s very close to it.

I’m tempted to rephrase this as turning off what Dennett calls the Cartesian Theater. Many of the people that Martin studied seem to have discarded this illusion.

Alas, the book says little about how to achieve Fundamental Wellbeing. The people who he studied tend to have achieved it via some spiritual path, but it sounds like there was typically a good deal of luck involved. Martin has developed an allegedly more reliable path, available at, but that requires a rather inflexible commitment to a time-consuming schedule, and a fair amount of money.

Should I want to experience Fundamental Wellbeing?

Most people who experience it show a clear preference for remaining in that state. That’s a clear medium strength reason to suspect that I should want it, and it’s hard to see any counter to that argument.

The weak version of Fundamental Wellbeing that I’ve experienced tends to confirm that conclusion, although I see signs that some aspects require continuing attention to maintain, and the time required to do so sometimes seems large compared to the benefits.

Martin briefly discusses people who experienced Fundamental Wellbeing, and then rejected it. It reminds me of my reaction to an SSRI – it felt like I got a nice vacation, but vacation wasn’t what I wanted, since it conflicted with some of my goals for achieving life satisfaction. Those who reject Fundamental Wellbeing disliked the lack of agency and emotion (I think this refers only to some of the harder-to-achieve versions of Fundamental Wellbeing). That sounds like it overlaps a fair amount with what I experienced on the SSRI.

Martin reports that some of the people he studied have unusual reactions to pain, feeling bliss under circumstances that appear to involve lots of pain. I can sort of see how this is a plausible extreme of the effects that I understand, but it still sounds pretty odd.

Will the world be better if more people achieve Fundamental Wellbeing?

The world would probably be somewhat better. Some people become more willing and able to help others when they reduce their own suffering. But that’s partly offset by people with Fundamental Wellbeing feeling less need to improve themselves, and feeling less bothered by the suffering of others. So the net effect is likely just a minor benefit.

I expect that even in the absence of people treating each other better, the reduced suffering that’s associated with Fundamental Wellbeing would mean that the world is a better place.

However, it’s tricky to determine how important that is. Martin mentions a clear case of a person who said he felt no stress, but exhibited many physical signs of being highly stressed. Is that better or worse than being conscious of stress? I think my answer is very context-dependent.

If it’s so great, why doesn’t everyone learn how to do it?

  • Achieving Fundamental Wellbeing often causes people to have diminished interest in interacting with other people. Only a modest fraction of people who experience it attempt to get others to do so.
  • I presume it has been somewhat hard to understand how to achieve Fundamental Wellbeing, and why we should think it’s valuable.
  • The benefits are somewhat difficult to observe, and there are sometimes visible drawbacks. E.g. one anecdote of a manager who became more generous with his company’s resources – that was likely good for some people, but likely at some cost to the company and/or his career.


The ideas in this book deserve to be more widely known.

I’m unsure whether that means lots of people should read this book. Maybe it’s more important just to repeat simple summaries of the book, and to practice more meditation.

Book review: The Longevity Diet: Discover the New Science Behind Stem Cell Activation and Regeneration to Slow Aging, Fight Disease, and Optimize Weight, by Valter Longo.

Longo is a moderately competent researcher whose ideas about nutrition and fasting are mostly heading in the right general direction, but many of his details look suspicious.

He convinced me to become more serious about occasional, longer fasts, but I probably won’t use his products.

Book review: Tripping over the Truth: the Return of the Metabolic Theory of Cancer Illuminates a New and Hopeful Path to a Cure, by Travis Christofferson.

This book is mostly a history of cancer research, focusing on competing grand theories, and the treatments suggested by the author’s preferred theory. That’s a simple theory where the prime cause of cancer is a switch to fermentation (known as the metabolic theory, or the Warburg hypothesis).

He describes in detail two promising treatments that were inspired by this theory: a drug based on 3-bromopyruvate (3BP), and a ketogenic diet.

Book(?) review: Microbial Burden: A Major Cause Of Aging And Age-Related Disease, by Michael Lustgarten.

This minibook has highly variable quality.

Lustgarten demonstrates clear associations between microbes and aging. That’s hardly newsworthy.

He’s much less clear when he switches to talking about causality. He says microbes are the root cause of aging, and occasionally provides weak evidence to support that.

I still have plenty of reason to suspect that much of those associations are due to frailty and declining immune systems, which let microbes take over more. Lustgarten doesn’t make the kind of argument that would convince me that the microbe –> senility causal path is more important than the senility –> microbe causal path.

He has a decent amount of practical advice that is likely to be quite healthy even if he’s wrong about the root cause of aging, including: eat lots of leaves, green peppers, mushrooms, and use low pH soap.

One confusing recommendation is to limit our protein intake to moderate levels.

He provides a nice graph of mortality as a function of BUN (see here for more evidence about BUN), which hints that we should reduce BUN by reducing protein intake.

He also notes that methionine restriction has significant evidence behind it, and methionine restriction requires restricting protein, especially animal proteins.

Yet I see some suggestions that protein (methionine) restriction is likely only helpful in people with kidney disease.

My impression is that high BUN mostly indicates poor health when it’s caused by kidney problems, and doesn’t provide much reason for reducing protein consumption, and least in people with healthy kidneys.

Lustgarten has since blogged about evidence (see the 7/11/2018 update) that higher protein intake helps reduce his homocysteine.

I have also noticed a (noisy) negative correlation between my protein consumption and my homocysteine levels. But that might be due to riboflavin – when I reduce my protein intake, I also reduce my riboflavin intake, since crickets are an important source of riboflavin for me. So I want to do more research into dietary protein before deciding to reduce it.

The book is too quick to dive into technical references, with limited descriptions of why they’re relevant. In many cases, I decided they provided only marginal support to his important points.

Read his blog before deciding whether to read the minibook. The blog focuses more on quantified-self-style reporting, and less on promoting a grand theory.

Book review: Principles: Life and Work, by Ray Dalio.

Most popular books get that way by having an engaging style. Yet this book’s style is mundane, almost forgetable.

Some books become bestsellers by being controversial. Others become bestsellers by manipulating reader’s emotions, e.g. by being fun to read, or by getting the reader to overestimate how profound the book is. Principles definitely doesn’t fit those patterns.

Some books become bestsellers because the author became famous for reasons other than his writings (e.g. Stephen Hawking, Donald Trump, and Bill Gates). Principles fits this pattern somewhat well: if an obscure person had published it, nothing about it would have triggered a pattern of readers enthusiastically urging their friends to read it. I suspect the average book in this category is rather pathetic, but I also expect there’s a very large variance in the quality of books in this category.

Principles contains an unusual amount of wisdom. But it’s unclear whether that’s enough to make it a good book, because it’s unclear whether it will convince readers to follow the advice. Much of the advice sounds like ideas that most of us agree with already. The wisdom comes more in selecting the most underutilized ideas, without being particularly novel. The main benefit is likely to be that people who were already on the verge of adopting the book’s advice will get one more nudge from an authority, providing the social reassurance they need.


Some of why I trust the book’s advice is that it overlaps a good deal with other sources from which I’ve gotten value, e.g. CFAR.

Key ideas include:

  • be honest with yourself
  • be open-minded
  • focus on identifying and fixing your most important weaknesses

Book review: Time Biases: A Theory of Rational Planning and Personal Persistence, by Meghan Sullivan.

I was very unsure about whether this book would be worth reading, as it could easily have been focused on complaints about behavior that experts have long known are mistaken.

I was pleasantly surprised when it quickly got to some of the really hard questions, and was thoughtful about what questions deserved attention. I disagree with enough of Sullivan’s premises that I have significant disagreements with her conclusions. Yet her reasoning is usually good enough that I’m unsure what to make of our disagreements – they’re typically due to differences of intuition that she admits are controversial.

I had hoped for some discussion of ethics (e.g. what discount rate to use in evaluating climate change), whereas the book focuses purely on prudential rationality (i.e. what’s rational for a self-interested person). Still, the discussion of prudential rationality covers most of the issues that make the ethical choices hard.

Personal identity

A key issue is the nature of personal identity – does one’s identity change over time?

Book review: Artificial Intelligence Safety and Security, by Roman V. Yampolskiy.

This is a collection of papers, with highly varying topics, quality, and importance.

Many of the papers focus on risks that are specific to superintelligence, some assuming that a single AI will take over the world, and some assuming that there will be many AIs of roughly equal power. Others focus on problems that are associated with current AI programs.

I’ve tried to arrange my comments on individual papers in roughly descending order of how important the papers look for addressing the largest AI-related risks, while also sometimes putting similar topics in one group. The result feels a little more organized than the book, but I worry that the papers are too dissimilar to be usefully grouped. I’ve ignored some of the less important papers.

The book’s attempt at organizing the papers consists of dividing them into “Concerns of Luminaries” and “Responses of Scholars”. Alas, I see few signs that many of the authors are even aware of what the other authors have written, much less that the later papers are attempts at responding to the earlier papers. It looks like the papers are mainly arranged in order of when they were written. There’s a modest cluster of authors who agree enough with Bostrom to constitute a single scientific paradigm, but half the papers demonstrate about as much of a consensus on what topic they’re discussing as I would expect to get from asking medieval peasants about airplane safety.

Book(?) review: The Great Stagnation: How America Ate All The Low-Hanging Fruit of Modern History, Got Sick, and Will (Eventually) Feel Better, by Tyler Cowen.

Tyler Cowen wrote what looks like a couple of blog posts, and published them in book form.

The problem: US economic growth slowed in the early 1970s, and hasn’t recovered much. Median family income would be 50% higher if the growth of 1945-1970 had continued.

Book review: Where Is My Flying Car? A Memoir of Future Past, by J. Storrs Hall (aka Josh).

If you only read the first 3 chapters, you might imagine that this is the history of just one industry (or the mysterious lack of an industry).

But this book attributes the absence of that industry to a broad set of problems that are keeping us poor. He looks at the post-1970 slowdown in innovation that Cowen describes in The Great Stagnation[1]. The two books agree on many symptoms, but describe the causes differently: where Cowen says we ate the low hanging fruit, Josh says it’s due to someone “spraying paraquat on the low-hanging fruit”.

The book is full of mostly good insights. It significantly changed my opinion of the Great Stagnation.

The book jumps back and forth between polemics about the Great Strangulation (with a bit too much outrage porn), and nerdy descriptions of engineering and piloting problems. I found those large shifts in tone to be somewhat disorienting – it’s like the author can’t decide whether he’s an autistic youth who is eagerly describing his latest obsession, or an angry old man complaining about how the world is going to hell (I’ve met the author at Foresight conferences, and got similar but milder impressions there).

Josh’s main explanation for the Great Strangulation is the rise of Green fundamentalism[2], but he also describes other cultural / political factors that seem related. But before looking at those, I’ll look in some depth at three industries that exemplify the Great Strangulation.

Book review: Capital in the Twenty-First Century, by Thomas Piketty.

Capital in the Twenty-First Century is decent at history, mediocre at economics, unimpressive at forecasting, and gives policy advice that is thoughtfully adapted to his somewhat controversial goals. His goals involve a rather different set of priorities than I endorse, but the book mostly doesn’t try to persuade us to adopt his goals, so I won’t say much here about why I have different priorities.

That qualifies as a good deal less dumbed-down-for-popularity than I expected from a bestseller.

Even when he makes mistakes, he is often sufficiently thoughtful and clear to be somewhat entertaining.

Piketty provides a comprehensive view of changes in financial inequality since the start of the industrial revolution.

Piketty’s main story is that we’ve experienced moderately steady increases in inequality, as long as conditions remained somewhat normal. There was a big break in that trend associated with WW1, WW2, and to lesser extents the Great Depression and baby boom. Those equalizing forces (mainly decreases in wealth) seem unlikely to repeat. We’re back on a trend of increasing inequality, with no end in sight.
