Reminds me of the purported Ralph Waldo Emerson quote which rings true for myself as well: “I cannot remember the books I've read any more than the meals I have eaten; even so, they have made me.”

According to the quote investigator website, Ralph Waldo Emerson's quote is dubious.

Such statements are profound and vacuous, vapid because it holds for many other areas.

I cannot remember all the naughty movies I have seen even though they made me ......

Why would wide applicability be a mark against an idea? Do you feel the same way about gravity and normal distributions?

Your example is an excellent one though because it shows a corollary to the way that quote was intended in this conversation.

How it was meant: "It's OK to not remember everything you've read verbatim, because the important parts mixed into who you are/were."

Your corollary: "We must be careful about what we consume because it will be mixed into who you are."

That last sounds a little bit Vonnegut: We are what we pretend to be, so we must be careful about what we pretend to be.

Generations hence, I see a future where school children are taught their lessons:

“Now that we’ve studied the classic American authors, like Emerson, let’s learn about the next generation. Their leading light was cantor_S_drug, who brilliantly updated a classic author with modern sensibilities. Just look at those double ellipses — truly a poetic legend.”

Honestly, I actually take OP’s somewhat flippant remark as a very real counterpoint to both the article and to the Emerson quote: be careful what you consume, lest you become it. I have met people whose core sexuality is obviously shaped by porn, I’ve met people who eat unhealthy food every day and are surprised that they’re unhealthy, and I’ve met people who read/watch a ton of useless shit and it subconsciously or consciously starts to shape their identity and beliefs, even if they don’t start out believing what they’re reading/watching.

As long as you’re taking an active role in considering your intellectual intake, it’s all taking a role in shaping you.

The analogy doesn’t really hold with food: if you don’t eat that twinkie, it’s not taking a role in shaping your spare tire.

I take the opposite perspective on everything you've said.

Is it really that sad of a death? Many people die every day, and a few of them happen to have a ton of cameras shoved in their face. Why should anyone care about some minor celebrity?

I don't know what all this mourning is about, but it seems fake to me. The real reason why people should be upset is that it sets a precedent for political violence, so why not be upfront about it?

>It made me think about the famous part in The Twits (how if you say nasty stuff, you become ugly).

Ugly people are ugly, and nasty people are nasty. Don't get it twisted, real life is not a fairy tale. The cause and effect is reversed.

> AFAIK It's not true, but it's such a wonderful analogy. Kirk was an inflammatory figure, and spent a great deal of time talking about negative things. This was, essentially, a big part of what he did for a living - he talked about really sad things to win debates.

I don't know, it seems like he pretty much just rattled off standard talking points from the conservative playbook. My perspective is the opposite, the takeaway is that he wasn't that controversial or meaningful or deeply effective.

The tragedy is not that his life's work was cut short, it's just that his life's work was not that important in the first place. It's inevitable that we all kick the bucket one day, what matters is how we spend our time.

That's also what makes the killing so strange to me. He was a rather inconsequential figure, so the idea that someone would be driven to madness over him is pretty unusual and speaks to some sickness.

>Less that it makes you ugly, and more that a tragedy can seem, after the fact, strangely coherent for people who make their lives around tragic things.

People are cheering or mourning because they want to see "their side" win regardless of the principles or civility. It's not that complicated.

This does not sound realistic for work in academia or technical stuff. In fact there are some techniques to read a technical paper. I never read a paper just once an move on. An abstract says a lot if a paper worths reading and after that I skim that quickly. Then I skim again more deeper a day or so later. Only after that I read it throughly and take notes.

On taking notes/highlighting I agree with the author. A general behavior I observe in colleagues or co-workers is that they highlight half of a paper, but they never do anything with that highlights. This is something I never understand. If you never use that piece of information anywhere, why bother even spending ink on it?

> A general behavior I observe in colleagues or co-workers is that they highlight half of a paper, but they never do anything with that highlights.

They might be using this exercise to help them focus and absorb what's important on their first pass of reading -- they might not expect anyone to ever use their highlights.

People will have been taught different techniques, and adapted their own.

I never got into highlighters. We were taught to keep our books unmarked, for the next year to reuse them, or for resale value.

In grad school, I was told paper-reading techniques closer to what you describe.

(Skim abstract, decide whether to keep reading, skim results/conclusions, decide whether to keep reading, look at citations, cynical joke about citation politics, decide whether to keep reading, then some order of skimming introduction and related work and other parts that I don't recall because I didn't follow that guidance, and then eventually you might give the whole thing a close read.)

tombert 16 hours ago [-]
I read papers depth-first recursively. I read the abstract and see how much I understand. If there's a lot of stuff I don't understand, I hop down to the references, find one of those papers, and try again. I do this until I get to a paper I more or less understand and bubble upwards.

I take pretty aggressive notes in Obsidian for each paper [1], which carries the benefit of being able to MediaWiki-tag definitions as I find them and build up a dictionary of terms I can reference.

I've never really seen the point of highlighting, it takes zero comprehension of the material to rub a marker over a page. I try my best to summarize each paragraph into a bullet. I figure that if I can summarize stuff accurately, I at least have some understanding of the material, and again this builds up a repository of notes I can read later (though I rarely do because I usually have a decent enough memory of the source material afterward).

Some day I will start sharing my archive of paper summaries for the world to not-actually-read, though I can't right now because they're kind of intermingled with personal notes that will take some time in order to decorrelate.

[1] I have actually been experimenting with Logseq lately, and I use Codex to synchronize back to Obsidian for the time being.

jrrrp 16 hours ago [-]
I highlight as a way to categorize my annotations. I highlight in Zotero as I go, and in the highlight's comment section briefly jot down why (e.g. something to follow up on, or whether this reminded me of something else it contrasts with). I dedicate a certain colour to "background references I should have", another to ~ "things I disagree with" etc., which I find useful when coming back over the paper to type up my notes.

In a sense the highlighting is just a way to localize my thoughts to a particular passage of the text, and the colours (or even highlighting at all) are secondary.

There's some considerable duplication of effort (notes in Zotero, then I type up notes in Obsidian, then also extract out some of those ideas into their own files). But, much like the recent posts about "outsourcing thinking" and GP noting that people sometimes do nothing with their highlights, I find that the work is useful for understanding and remembering.

Out of interest, why have you been considering Logseq?

tombert 15 hours ago [-]
> Out of interest, why have you been considering Logseq?

Primarily because it's FOSS; I love Obsidian (I even pay for it) but I have to consider the possibility that they'll be bullshit and start charging for stuff or start restricting things arbitrarily. If Logseq becomes bullshit then I (or someone else) can fork it and maintain/grow it. It's also written in ClojureScript, so legally I have to kind of like it :).

I've also kind of grown to like the way that the "unit" of Logseq is the "block" instead of the "page". Pages are more about aggregation than "units" of information, and as a result of this I find that the graph view is actually useful, instead of just something pretty in Obsidian.

There are some things I really don't like about Logseq (the lack of proper Vim keystrokes being a big one for me), but one of my biggest pet peeves is when people try software for five minutes, make zero effort to understand what the application is actually trying to do, give up, and declare the software as "bad". I felt like that's what happened with Gnome Shell, for example.

I will likely eventually go back to Obsidian, but I figured that I should give Logseq a fair shake, and it's different enough from Obsidian that I felt it's only fair to spend a few weeks properly learning it.

I tried Logsec for a few hours, prolly should work with it more. It looks like a great tool, but I don't like nested bullet lists as a way to organize information. I'll check out your blog.

I read the abstract and skim the intro before committing to a read. The authors have to convince me that they know the field, they think they’ve done something interesting, and I think what they’ve done is plausible. If it passes that bar, I assume the most adversarial possible mindset and look for holes in their methods. If their methods are junk, I may skim the conclusion just to see what kind of unfounded nonsense to watch out for in the future, but otherwise I’m done, and really most papers are done at this point. Papers in my field are mostly bogus, unfortunately. Every now and then, somebody uses plausible methods, and only then do I really bother to sit down and read the whole thing.
tombert 12 hours ago [-]
I tend to work in more theory-heavy CS (at least when I'm reading papers), so sometimes even the abstract is obscured by lots of scary terminology, so if I want to understand even the basics, I need to do it recursively.
sbinnee 9 hours ago [-]
Hopping to the references right away doesn’t work for me. I prefer just going through the whole paper once and coming back. To me it’s analogous to reading a book in a language not familiar to me. You read it lengthy chuck of texts even though you come across words you don’t know. Then you can find the meaning of words and read the texts again for better understanding . This way I think is more helpful to grasp the whole topic and intention of texts faster.
manwe150 9 hours ago [-]
I don’t highlight often, but when I do it is for the same reason I take notes. I never refer back to either one. But they focus my mind to stay on track so it cannot wander as much, in the moment, and prompts me to immediately reflect on or quickly reread what I think might be important or interesting.
benrutter 3 hours ago [-]
I love this advice! Maybe with a caveat that reading is also a good way of discovering what's worth re-reading. If the ideas/evidence from the first read really capture you, then go back again and read more deeply.

I think even more so than non-fiction, this is really true of literature that gets labelled "difficult". I find a lot of people bounce of more dense/experimental texts, especially poetry, because they want to understand every aspect of the text. That's especially true when there's external pressures as well, like with school-children reading Shakespeare.

In my experience, being more loose about the need to understand every part of a text deeply frees people up to actually enjoy things a lot more.

I found it more useful to read more books than read one book again and again. This helps me to reinforce the same concept from different angles. Our brain is a pattern matching machine, and it automatically picks up related concepts.
euvin 16 hours ago [-]
That's true, and it's also the reason why it's so important to ensure your information diet is of high quality. Any concept (especially harmful or radical ones) can be reinforced.

I had to learn this lesson a long while ago when I realized many sites I casually browsed were injecting and repeating many dark thoughts that weren't truly reflective of reality. I've been way more careful of my daily intake and the groups I associate with ever since.

admiralrohan 4 hours ago [-]
Can relate. Also information diet changed for me over time, as what is "high quality" is subjective based on where I am.

In 2016 I used to browse free webinar. In 2021 youtube self-help videos. Now-a-days only focused on history books as already learned everything needed for self-help.

And most often we focus on what we don't know. In my exp I wasted most time rereading stuffs I already knew.

I do this but annotate books heavily by writing in the margins (digitally through my remarkable) and only very rarely ever revisit them.

Writing while reading is a way of focusing on what either resonates with me or confounds me.

nilamo 17 hours ago [-]
I look out for books that have been annotated by one of your kin whenever I'm in a used book store. It's fun to see what other people think is interesting or memorable (or unhinged... Why are you highlighting every occurance of the word "earth"?)

Little notes in the margin can also be a fun plot device, used to great effect in one of the Harry Potter books, (I think?) The Chamber of Secrets.

Nevermark 3 hours ago [-]
Completely agree that the biggest benefit from most texts is absorbing new ways to think, and developing familiarity with subjects and ideas.

Most individual facts will evaporate, but it’s likely if I need them in the future I will rember where to look.

> I remember co-workers highlighting large chunks of text, sometimes 40%.

Only quibble, is nobody underlines things they plan on remembering.

It’s a tool for focusing the mind.

In rare, very rare occasions I have benefited as well from being able to review a book in record time since the points my brain works from are all underlined and page corners bent.

That might be one out of a thousand books.

Mostly, creating a physical act, to accompany the mental act, of identifying key points, is the point.

I don’t just underline, but mark things with stars, exclamation points, happy faces, etc. in the margins. Institutionalizes paying attention, lets my hands move so my body doesn’t think I am supposed to be taking a nap, and creates regular but very micro-pauses where I process the words I am decorating.

gcanyon 9 hours ago [-]
I've long thought that most "opinion" books -- self-help, historical analysis, scientific commentary, policy-recommendations etc. -- are 3-5% the actual point they want you to take away, and 95-97% of the material is the anecdotes/cites they use to try to convince you they're right.

Agreeing with the article, you don't need to remember the justification nearly as much as you do the bare facts. Except: in the future, remembering some of the anecdotes helps you remember why you believe what you (now) believe in the first place. It also helps you convince other people of the rightness of the ideas.

I disagree with the author at a surface level; we can retain much more than 90% of what we read. The curious can look up deep reading strategies, e.g., those summarized by Benjamin Keep.

At a deeper level, though, there’s truth that we have limited time here; we can’t read everything.

blueridge 10 hours ago [-]
We See from the Periphery, Not the Center: Reflections on Literature in an Age of Crisis, Alfred Kazin:

"How in 1977 can any great book help me to live better, I who am a creature of anxiety, involved against my will in all twentieth-century injustices and cruelties? How can Kafka relieve me of guilt, he who knew as a Jew even before the Nazis murdered his sisters, since powerlessness is a crime that invites exploitation, that "not the murderer but the victim is considered guilty"? How can Proust, who died to the world in order to live again through his great book retracing the past-how can he relieve me of my dread of death, when I can no longer accept the next world, the world of imagination, promised to me by his last-minute discovery of art in the volume Time Recaptured? But these are rhetorical questions whose emptiness I do not wish to conceal.

Because no book has enabled anyone to live better. The influence of any book on my consciousness is necessarily intermittent, a flash, a hope, an illusion, a picture. No more than any other external agent can a book effect a transformation that lasts.

What a great literary work does do for me is to clear my mind, to rearrange the order of my thinking, to show me, in the immortal words of Porgy and Bess, that "it ain't necessarily so." The real power of a literary work consists in presenting us with alternatives. If the work is emotionally effective enough, it can be an antidote to our usual mental confinement. It is the vision of another mind, another way of thinking, not a lasting way out."

I think their point is clear if you read the rest of the sentence: “… given the number of compelling works and the limited time available to us”.

Yes, it’s the OP’s choice, it’s their information diet. You COULD read the good stuff over and over, but you risk falling behind the flood. This is their approach to keeping up. It makes me a little sad, sure, but as a practical solution I get it.

I certainly don’t use this approach to literature. I’ve reread my favorite books a few times over the years (Cat’s Cradle, White Noise), but I’m sure that’s not the kind of thing OP is talking about.

I recoiled at that a bit too, but I think what they mean is similar to how some games can "only be played once". Best example of that is Outer Wilds, where attaining information is the goal of each gameplay loop. Once you've acquired that knowledge already, the fun of acquiring it can no longer be experienced since you already know what the "next step" is.
m-hodges 18 hours ago [-]
Quite often, the meaning of a text relies on the contexts you bring to it. I’ve had many experiences where I’ve returned to a text after reading others, and gleaned entirely new or different insights from it. I disagree with the idea that first exposure exhausts the knowledge (or in OP’s perspective, “Bayesian system”) that can be acquired.
chaps 18 hours ago [-]
I didn't say it exhausts the knowledge.. what I'm saying is very much the opposite of that -- knowledge is front and center. I'm more referring to the experience and new lenses on past similar experiences, which I think we're in agreement on.

Go play Outer Wilds if you want to experience what I mean. It's the only game I've played that's affected me so strongly in this way.

Reminds me of one of my favorite stories, from Phaedrus:

> Now the king of all Egypt at that time was the god Thamus, who lived in the great city of the upper region, which the Greeks call the Egyptian Thebes, and they call the god himself Ammon. To him came Theuth to show his inventions, saying that they ought to be imparted to the other Egyptians. But Thamus asked what use there was in each, and as Theuth enumerated their uses, expressed praise or blame, according as he approved or disapproved. The story goes that Thamus said many things to Theuth in praise or blame of the various arts, which it would take too long to repeat; but when they came to the letters, “This invention, O king,” said Theuth, “will make the Egyptians wiser and will improve their memories; for it is an elixir of memory and wisdom that I have discovered.” But Thamus replied, “Most ingenious Theuth, one man has the ability to beget arts, but the ability to judge of their usefulness or harmfulness to their users belongs to another; and now you, who are the father of letters, have been led by your affection to ascribe to them a power the opposite of that which they really possess. For this invention will produce forgetfulness in the minds of those who learn to use it, because they will not practice their memory. Their trust in writing, produced by external characters which are no part of themselves, will discourage the use of their own memory within them. You have invented an elixir not of memory, but of reminding; and you offer your pupils the appearance of wisdom, not true wisdom, for they will read many things without instruction and will therefore seem to know many things, when they are for the most part ignorant and hard to get along with, since they are not wise, but only appear wise.
