A few thoughts on Braiding Sweetgrass



Abundance ahead?

When I was asked to write down one word that comes to mind as I read the book, my first word was "Native" after only a brief foray into the book. But after more time with it, I land on "gift". The book is a gift to me in a time when I feel at sea with respect to what to do about human caused climate change and climate recklessness. In some sense, the world doesn't need us. It has lived long before us and will live long after us. If we cannot live in harmony with it, perhaps we are a failed experiment as a species. 

In the past, I believed the way out of this situation was a combination of science, abundance and homeostasis. Engineering problems seem to emerge just in time, right when we need them. See for example Abundance: The Future Is Better Than You Think by Peter H. Diamandis and Steven Kotler. 
Predictions about the future of the “Great Horse Manure Crisis” were grim. One commentator predicted that by 1930 horse manure would reach the level of Manhattan’s third-story windows. 
The problem seemed insurmountable. 
And it wasn’t limited to New York. In England, The Times newspaper predicted in 1894 that, “In 50 years, every street in London will be buried under nine feet of manure.” 
Then, in the early years of the 20th century, hope began to glimmer. A new form of technology, the automobile, began to make its presence felt. Silent, swift, and, most importantly, clean, these machines promised a solution to the problem that had plagued the city for decades.
Recently, however, I have felt less secure about the abundance ahead. The research for Diamandis and Kotler's book, for example, did not unearth the fact that the problem of horse manure piling up in New York City was an urban legend.

Reading Kimmerer's chapter Old-Growth Children, 
Opportunistic or Pioneer species have adaptations to survive after disturbance...Their goal is to grow and reproduce as quickly as possible...The key to success is to get more of everything than your neighbor. 
Later, in a chapter titled Windigo Footprints, Kimmerer explores the diseases of excess and self-destructive practices such such as alcohol and drug addiction, gambling, technology through the lens of the story of the Windigo, "a human whose selfishness has overpowered their self-control to the point that satisfaction is no longer possible." 

Multinational corporations have spawned a new breed of Windigo that insatiable devours the earth's resources not for need but for greed. Extractive capitalism thrives in a mindset of scarcity. However, other books by Rutger Bregman such as Humankind and Utopia for Realists and Stephen Pinker's Enlightment Now and The Better Angels of Our Nature: Why Violence Has Declined help me sleep better and restore my faith in humanity. 

I think there is some benefit in viewing these problems through Stephen Wolfram's lens of computational irreducibility. This concept, if applicable here, would suggest that the predictions that we make about the futures for sufficiently complex systems (e.g. human behavior, technology, climate change, forever weather) are necessarily incomplete. So, for these systems, our only option is to make short term forecasts and if we want to know the outcome, we have to be willing to see the entire experiment through since "no shortcut" (prediction or simulation) can exist, in principle. 

Interestingly, the universe, itself, may abide by this principle on a quantum scale (for more: read about the mathematical success of the path integral formulation—aka "summing over histories"—and the possible connections to Hugh Everett's Many Worlds view). Though you need not commit yourself to Many Worlds to enjoy Feynman's mathematical program. See, for example, Feynman's QED for a great read on how quantum calculations can be done on some beautiful applied problems like how white light reflects as a rainbow, due to the pitting on compact disc surfaces, can be understood with a quantum calculation. To read some more about the Many Worlds view, I would recommend either Brian Greene's Hidden Reality or Max Tegmark's Our Mathematical Universe.

Other things I liked about the book

  1. The Thanksgiving Prayer (PDF)
  2. The idea of verbs like: "to be a bay", "to be a hill", "to be a Saturday"
  3. The lesson of the berry: "All flourishing is mutual"
  4. A giveaway economy. What happens when there is a break in at a giveaway. This is what she says is happening via extractive capitalism 
  5. "Ceremony is a way to remember"
  6. "When Allied Chemical was a gleam in the eye of a smokestack."
  7. As a vegan, I began The Honorable Harvest chapter (PDF) with trepidation. After reading it I remain a vegan. And, Kimmerer's point is not about diet but about living according to an ethic. I did really appreciate the entire chapter. Below is a list of principles that Kimmerer identified in case you don't have the time to read the whole chapter:
    1. Know the ways of the ones who take care of you, so that you may take care of them.
    2. Introduce yourself. Be accountable as the one who comes asking for life.
    3. Ask permission before taking. Abide by the answer.
    4. Never take the first. Never take the last.
    5. Take only what you need.
    6. Take only that which is given.
    7. Never take more than half. Leave some for others.
    8. Harvest in a way that minimizes harm.
    9. Use it respectfully. Never waste what you have taken.
    10. Share.
    11. Give thanks for what you have been given.
    12. Give a gift, in reciprocity for what you have taken.
    13. Sustain the ones who sustain you and the earth will last forever.

Junot Diaz 100 Books a Year Challenge (Major Update)

14 years ago I set the goal of reading 100 books in a year. (spoiler alert: I failed to achieve this goal but I did read a lot more than I would have had I not set the goal)

A few years later, I read this great post visualizing our life in weeks (from Tim Urban at Waitbutwhy).


Then in 2024, Dino Ambrosi came to my school to launch Project Reboot (here is a TEDx talk he gave making great use of this graph and helping our faculty and students understand how it can be a useful tool to think about how we use and fail to safeguard our time).


After his talk, whenever I thought about possibly consuming media, I remembered to think to myself about the ratio of time it took to produce the content compared with the time it would take me to consume it: if the ratio was high enough and I had the time and inclination, I would try to consume it. This led me to try reading a lot more books and long form content and try to read a lot less news. 

As I watched my behavior, I realized that my habits were getting in the way. I would have an itch to pull out my phone and read the news and I realized that I was not mindful enough yet to resist it. So, in 2024, I bought myself and my wife two Kindle eReaders, and I connected to the Libby App. Whenever the itch arose to read the news, I would rewire my brain, pulling out the kindle instead. The following timeline represents the raw data of my borrowings since that December 1.5 years ago:


Going through it with a finer tooth come (removing duplicates and books I didn't finish), I have the following books read (or listened to) over that 1.5 year period:

This summer, I plan to reach for my kindle (or pull out my earbuds much more often). I want to focus on reading because I believe it has enriched my life significantly. The posts that follow will represent some of my thoughts, book by book, one book at a time.

A couple of good reads

I recently read and enjoyed three excellent books:

  • George Saunders' The tenth of December - The best fiction I have read in a long time. I was drawn to this book by a wonderful article in the NY Times article (George Saunders has written the best book you'll read this year). The book completely lives up to the hype. I couldn't put it down. I am currently reading another of his books (CivilWarLand in bad decline). Check out two of his excerpted short stories from tenth of December and you'll see what I mean (1 and 2).
  • Jim Holt Why does the world exist?: an existential detective story - A wonderful read on why there is something and not nothing. This book goes well with two others I've read in recent years (Brian Greene The hidden reality and Lawrence Krauss A universe from nothing). Holt's approach is more philosophical, and he does a wonderful job framing the problem from this perspective. I was surprised that he even provides his own ontological justification for why there is something rather than nothing and why we could rationally expect that something to be utterly mediocre.
  • Julian Barnes The sense of an ending - Barnes' engaging (meta-)commentary on the narrative impulse. The book's self-referential title says it all. We need crave the sense of an ending just as we crave the sense of a reason in an unreasonable world. This is all succinctly put by Barnes when he has a character quote: "History is that certainty produced at the point where the imperfections of memory meet the inadequacies of documentation."

 Currently reading


  • Oliver Sacks Hallucinations - excellent book that resonates with two questions that I can't shake: what is the physical basis of the subjective (first-person) experience and how different can it become. If you haven't read Sacks' Altered States in the New Yorker you really must.

Updates on The Junot Diaz Challenge and a new book club!

On September 29, 2011, I set the goal of reading 100 books in a year. The goal was a large one and pushed me to do a lot of reading that I definitely would not have done otherwise! However, in case you are wondering, I totally failed at this goal by pretty much any measure, despite my best intentions:
In case you are counting, you will notice that I am a bit behind my pace: we are one month down and I have read 5 books (off my 6 books a month pace while teaching). Not to worry, I am still working hard on this project and will be back on top of my rate in no time. Stay tuned!
Over the course of the year, I have occasionally posted about my readings, but recently, I have been kind of radio-silent! This is the long overdue post to update you on my progress.

In November, I encountered what would become a major flaw in the 100 books in a year ideal and subsequently my inability to set a new goal: the very real time restraints imposed by my teaching schedule combined with a rather arbitrary restriction (that I read a book); and what is a book? Certainly not a chapter, article, blog post. Do short books count equally as well as long books? So we are penalizing longer books with this system? What about podcasts, do these count not at all?

Basically, I reset my goal to find interesting questions to consider and just do that with my free time as much as possible (limiting time spent doing things that distracted me from this goal).

I have had a wonderful time with the challenge I set for myself and over the course of the year I learned about a lot of really cool stuff!

Here is a partial list of things I thought about, learned and read:

Non-Fiction






Comedy



Philosophy



Fiction













Blogs/Articles (noteworthy)







Good source of books off copyright





Excellent PDF about the creativity needed to do real mathematics

I have started an Evidenced-based education group at St. Andrew's and am looking forward to reading a couple good books (Sahlberg and Perkins) on the subject as well as studies.
