NOTES:

My dad liked the book but gave me his critique that Frank doesn't address the elephant in the room, which is racism. Working-class whites, the victims in Frank's narrative, also have a reputation for being racist (though I can't find a definitive study proving or disproving this stereotype). This may not be new: FDR was not progressive on race, and that probably helped his popularity. But again, I'd want to see actual studies before making any conclusions.

The more indisputable part of my dad's critique concerns Frank's silence on how workers' unions have over time become corrupt and no longer serve the interests of workers, as explained in this review: https://www.currentaffairs.org/2016/08/review-listen-liberal

lots of veggies great for gut health

microfasting (i.e. not eating late at night)

frequent movement throughout the day better than one long workout

HIIT can be done in few-minute bursts anywhere: jumping jacks or burpees in the house, a short sprint while out on a walk, etc.

NOTES:

I used to like Jordan Peterson years ago when he was a little less obviously right-wing, and when I was a lot less grown up. I wish I'd had this video back then.

NOTES:

Among fans of active/immersive Greek, this book is not as popular as Athenaze, Alexandros, and Thrasymachus. I can see why: it's terrible at providing a beginner-friendly gradual progression with lots of repetition. Even so, I like it better than all the others because instead of tedious stories about daily life on the farm or retellings of the same old myths, it tells stories set in ancient Athens, strongly rooted in history or literature, and often quite funny.

NOTES:

Other books on this topic that I've tried are huge downers and hard to stomach. This book, though it duly gives a historical overview chock full of baddies, sets itself apart in how much space it devotes to possible solutions (nearly half the book!). The audiobook narrator is very lively as well, one of the best I've heard in nonfiction.

NOTES:

In my first read-through this was a revelation, as if I'd never known what programming means. I didn't get as much out of it on subsequent re-reads.

Single Responsibility Principle (Responsibility-Driven Design)

call accessors, do NOT use data directly; also hide data structures

single responsibility for methods too! this avoids the need for comments

dependency injection (move dependencies outside of classes, e.g. external class names), or if constrained then isolate dependencies in initialize

also encapsulate external messages in separate wrapper methods

use keyword arguments w/ defaults (can be messages to self), or if constrained then wrap (external) positional methods in a factory (module)

think about direction of dependency: depend on abstractions/interfaces or classes w/ few dependents & not likely to change

use sequence diagrams (UML) to form an intention about a program, to define public interfaces (message-based design), before writing first test, before writing classes

shift as much as possible into private interfaces (the kitchen vs. the menu); in public interfaces focus on the "what" not the "how"; this way, make each class's context small; classes shouldn't even know what their dependents do, but should just ask them to do their part

do not define public/private, just name methods in private interface like _some_private_method

to solve Demeter violations, decouple code by improving public interfaces (don't chain because it increases knowledge and overspecifies the context), not just by delegation with wrappers

recognize hidden ducks: case statements that switch on class, kind_of?/is_a?, responds_to?

when creating a superclass, start blank and promote abstractions (don't start w/ existing class and demote concretions)

template method pattern: def initialize(**opts); @tire_size = opts

:tire_size ¦¦ default_tire_size

but supply an implementation for every message a class sends, like this: def default_tire_size; raise NotImplementedError, "#{self.class} should have implemented #{__method__}"; end

set up hooks in the superclass for subclasses to override (don't force subclasses to send super at the end of overrides) e.g. post_initialize() and local_spares()

composition is more flexible than inheritance/modules, with fewer dependenies (see recumbent_config)

ruthlessly delete unused code

when testing involves roles, use stubs/doubles (fake/idealized objects in a role)

prove command messages with mocks

to test duck types (roles), include test modules (…InterfaceTest)

test inherited code (…InterfaceTest and …SubclassTest)

NOTES:

Just as good as the book.

NOTES:

Shows how deeply not just Trump but the GOP itself is a threat to democracy, because even now out of self-preservation they haven't as a whole repudiated Trump. Also shows by how slender a thread the rule of law prevailed: Pence was indecisive about whether he would validate the electoral college votes on Jan. 6, and who knows what would've happened if he had decided otherwise.

NOTES:

The first few chapters provide a great history lesson. The last few are a depressing look at how most churches have failed gay people, but also an inspiring look at how some churches are doing better.

NOTES:

Lots of good ideas for self-examination and putting out emotional fires, e.g. morning + evening review of the day, looking at a present emotional disturbance from the standpoint of ten years in the future.

The first of Marcus's ten thinking strategies against anger really hit me: that we are naturally social beings designed to help one another, so we should seek fellowship with those around us even if it's a bother. "He adds, 'Nor can I be angry with my kinsman nor hate him for we have come into being for co-operation,' and that to obstruct one another by feeling resentment or turning our back on others goes against our rational and social nature. Indeed, he says that the good for a rational creature lies, partly, in having an attitude of fellowship toward others. Marcus also goes so far as to claim that ignoring our fellowship with others is a form of injustice, a vice, and an impiety because it goes against Nature." (cf. Meditations 2.1, 5.16, 9.1)

NOTES:

This is an amazing way of understanding why the Bible has warts. Essentially, it's for the same reasons that God chose to be incarnated in Jesus, a carpenter's son who was crucified as a criminal.

I'm not sure the excursion into Barth was necessary, seeing as how a book like this should be as accessible as possible to normal people who are not theology nerds but who are turned off by the Bible's imperfections.

Boyd suggests that the OT Israelites were led by demons at some points when they thought they were hearing God: "The fact that Paul instructs us to reject any Gospel other than the cross-centered Gospel he preached, even if it be delivered by “an angel from heaven” (Gal 1:8). provides further reason for us to conclude that Moses was mistaken when he thought he heard Yahweh instruct him to have the Israelites mercilessly slaughter “anything that breathes” in certain regions of Canaan (Deut 20:16)." and "Although Elijah is generally depicted as a hero of the faith in Scripture, and although the fire that fell from the sky was clearly supernatural, Jesus rebuked his disciples for wanting to follow Elijah’s example. Some early manuscripts add that Jesus suggested that James and John were of a “different spirit” than he. If this reading is accepted, as I’m inclined to think it should be, Jesus was suggesting that Elijah’s destructive miracle had a demonic quality to it."

Postscript "Beautiful Scars": putting together a broken vase with the Japanese restorative art of Kintsugi: "Moreover, this lady came to see how her masterpiece told a particular unique story of hope rising out of hopelessness and beauty rising out of brokenness. In fact, she shared that these cracks greatly increased her personal connection to her vase because they now had something in common: a story of brokenness and restoration. In fact, for her, those beautiful cracks became a symbol of her own brokenness and of her need to always trust that God is working in her to “turn her ashes into beauty,” as one of her favorite worship songs put it. But to appreciate this, my friend had to be willing to let go of her previous dream of getting as much of her pre-broken vase back as possible."

NOTES:

Ch. 8: "In Romans 2:1, “Passing judgment on another” is the sin that is equated with the licentiousness, greed, and lust portrayed in 1:18-32. The posture of judgmentalism entails essentially the same sin described in the previous chapter. But this only raises the further question: What does out-of-control lust have in common with judgmentalism? In both cases, what Paul seems to have in mind is the attempt to advance one’s own honor, status, and will at the expense of others. This interpretation is confirmed by a second piece of evidence found a bit later in the passage, in Romans 2:8, where Paul characterizes those who are subject to divine judgment as “those who are self-seeking and who obey not the truth but wickedness.” The Greek word translated here as “self-seeking” (eritheia) is an uncommon word and somewhat difficult to translate. But most interpreters follow the lexicon’s suggestion of “selfishness” — or, even better, “selfish ambition.” What is at stake here is the thirst for honor, status, and prestige that is so prevalent in the ancient world.3 Hence, as Paul sees it, what lustful pagans have in common with self-righteous judgmental Christians is that both are driven by the thirst for their own agenda — their own way, their own status, their own honor — while ignoring the concerns of everyone around them, particularly those of the living God. At the root of all sin is the will to power that resists the posture of humble gratitude and trust that marks human life as God intends it. Indeed, as Robert Jewett has argued in his recent magisterial commentary on Romans, this is the discovery that marked Paul’s own conversion: the realization that his zeal for the law was in reality selfishly driven by his own longing for status and honor. In commenting on Romans 7:7 (“I would not have known what it is to covet if the law had not said, ‘You shall not covet’”), Jewett defines the core problem driving covetousness as “the sin of asserting oneself and one’s group at the expense of others.”"

Lots of other memorable bits. Maybe I'll add them here when I re-read.

NOTES:

A good follow-up is The Bible and Sexuality by the same author

Ch. 5 (What Is Ethical? Interpreting the Bible like Jesus): Two biblical examples of reinterpreting biblical commands for the sake of ethics: (1) lighter rules for slaves in Deut. 15:12-18 than in Ex. 21:2-11, (2) exceptions on divorce by Paul (1 Cor. 7:12-15) and Matthew (19:9) not given by Jesus (Mark 10:11-12). In the second example, Jesus' command was reinterpreted despite being grounded in a creation ordinance. Also, other examples of handling laws with discernment of human need: David eating the tabernacle bread (Matt. 12:3-4), Jesus telling his accusers that it's OK to help people in need on the Sabbath (and Sabbath is another creation ordinance!).

"Even though Jesus honored the Sabbath, he was accused of violating it. In response to his accusers, he took their objections at face value and taught *the fundamental reason* for God’s law, namely, God’s law is made for humankind, not humankind for God’s law (Mark 2:27). In other words, God’s ordinances are always *on behalf of* people and not for the arbitrary appeasement of God’s sensibilities. For that reason, even a creation ordinance requires discernment to be properly interpreted and applied. Lest we think such interpretative work was only for the inspired biblical authors, Jesus indicates otherwise. His instructions for interpreting the Bible were given to ordinary religious leaders of his day (i.e., the faith community). He confronted them for failing to adequately engage the deliberative process. In other words, the interpretive practices we see Jesus and the biblical authors employ are examples given for us to follow. Jesus wanted his accusers to learn how to be better readers and appliers of Scripture."

Paul too advised discernment about applying Sabbath laws in Col. 2: "do not let anyone judge you with respect to food or drink, or in the matter of a feast, new moon, or Sabbath days—these are only the shadow of the things to come"—a point reiterated in Heb. 10:1 "The law possesses a shadow of the good things to come."

Ch. 6: The PCA has engaged in casuistry (development of case law) to add another exception to Jesus' prohibition of divorce, in cases of domestic violence.

Ch. 7: Augustine believed intersex people were not a product of the fall: "For God is the Creator of all things: He Himself knows where and when anything should be, or should have been, created; and He knows how to weave the beauty of the whole out of the similarity and diversity of its parts. The man who cannot view the whole is offended by what he takes to be the deformity of a part; but this is because he does not know how it is to be adapted or related to the whole. … God forbid, however, that someone who does not know why the Creator has done what He has done should be foolish enough to suppose that God has in such cases erred."

NOTES:

It was a huge relief to learn that it's OK to write only system specs and model specs, it's OK if I'm not mocking and stubbing, and it's OK if I'm not always doing TDD. Most other testing guides that I've read are depressing because of the unattainable purity of their approach or because of the overwhelming amount of terminology and tools. But this is a breath of fresh air.

Here's a summary: https://books.google.com/books?id=G0e4DwAAQBAJ&pg=PA103

I found this when I was pondering the significance of death in the Christian story vs. the material history of the universe. Christians who accept science must admit that death and decay are built into the universe and so were there from the beginning, contra the traditional story of the fall. For most, this means God intended for death to be a natural part of the world. But to me this is unsatisfying, both on a gut level and also in how central to Christianity it is to view death as a bad thing.

Boyd's is a much more spiritually and poetically fulfilling theory for explaining the suffering "built into" nature. I couldn't help recalling Tolkien's creation account in The Silmarillion, because I think it is an amazingly vivid portrayal of the same theodicy: https://archive.org/details/TheSilmarillionIllustratedJ.R.R.TolkienTedNasmith/page/n25/mode/2up

But the Silmarillion's creation story, unlike Boyd's take, has classical theist overtones in that the gods play the universe into being as a song, and then they play the song back as if they are outside of time.

UPDATE: Originally I gave this a 3, but I'm bumping it up to a 4 after re-reading the first several chapters, and after watching videos by Inspiring Philosophy that brought some of Walton's key points into greater focus: https://inspiringphilosophy.org/evolution-and-genesis/ and https://www.youtube.com/playlist?list=PL1mr9ZTZb3TUeQHe-lZZF2DTxDHA_LFxi.

I *wanted* this to be 4 stars because out of all arguments against Genesis 1 as describing material creation, this book has the most coherent thesis: that Genesis 1 describes functional (not material) origins.

But the book has a number of shortcomings: overly academic language, arcane side-discussions, too much credit given to Intelligent Design.

Genesis 1 as temple dedication ritual is a fascinating idea.

Walton believes that Genesis 1 still refers to a historical 7 days—not when God created everything materially, but when he proclaimed the functions of everything. I think this is unnecessary and it feels a bit awkward to say that God showed up a few billion years after the Big Bang to proclaim all the functions, when the universe had been developing quite nicely without the functions having been proclaimed. But for people who refuse to abandon the historical 7 days, it is an option.

In an email to Dr. Ball, after he recommended this book: Coincidentally I stumbled upon Walton's book just a few weeks ago and I'm almost done reading it now. It is the most convincing explanation of a "non-literal" reading of Genesis 1 because he explains that the most literal (or "face value") reading does not say anything about the material concerns that today's "literal" readings put front and center. While many Christians lament that scientists' views infect people's faith, it's funny that Walton turns the tables and points out that "literalist" readings are themselves imbued with a modern scientific mindset that has no place in understanding what God was saying to the ancient Israelites.

NOTES:

There are many more "intermediate forms" in the fossil record than I thought, and even some existing today such as walking fish. My other main doubt—how complex features could possibly evolve if they aren't useful in an intermediate stage—was also put to rest, because generally these features evolved only if they were useful in a half-formed state: for example, those walking fish have fins that have evolved into legs because in their environment (shallow water) it helps them escape predators by running onto land, or it helps them move from one small body of water to the next. Cf. the famous dictum "Evolution is a tinkerer, not an engineer." Even humans have very imperfect features that nonetheless work well enough, e.g. knees and ankles that are pretty fragile and not great for bipedal locomotion, but they usually work. (An ostrich's legs are much stronger and more resilient.) Similarly, our eyes are not nearly as good as some other types of eyes that have independently evolved, such as octopus eyes.

50,000 or 75,000 years ago there was a serious bottleneck in homo sapiens evolution, estimated anywhere between 40 and a few thousand mating pairs. This is a more severe bottleneck than happens in most species, and for homo sapiens there seem to have been other similarly bad bottlenecks.

The most staggering passage: “The blessing was a mercy. He was offering me the same terms of surrender he had offered my sister. I imagined what a relief it must have been for her, to realize she could trade her reality—the one she shared with me—for his. How grateful she must have felt to pay such a modest price for her betrayal. I could not judge her for her choice, but in that moment I knew I could not choose it for myself. Everything I had worked for, all my years of study, had been to purchase for myself this one privilege: to see and experience more truths than those given to me by my father, and to use those truths to construct my own mind. I had come to believe that the ability to evaluate many ideas, many histories, many points of view, was at the heart of what it means to self-create. If I yielded now, I would lose more than an argument. I would lose custody of my own mind. This was the price I was being asked to pay, I understood that now.

There may be a redivision of the land, but the natural inequality of men soon recreates an inequality of possessions and privileges, and raises to power a new minority with essentially the same instincts as in the old. The only real revolution is in the enlightenment of the mind and the improvement of character, the only real emancipation is individual, and the only real revolutionists are philosophers and saints."

Oh, and now that oil for energy is down, they're ramping up single use plastics even more.
