Will MAGA panic subside with an old white man back in the presidency? How American political parties have disintegrated in the past, and the Republican party may now be doing. How Britain has become the dumbest society in the world, because of changes that parallel those in the US.
Carl Sagan: BILLIONS & BILLIONS: Thoughts on Life and Death at the Brink of the Millennium (1996, Random House)
This was Carl Sagan’s final book, it says, published in 1997 not long after his premature death in 1996 at age 62. Actually, there was one further book, The Varieties of Scientific Experience, published in 2006, based on a series of 1985 lectures, belatedly assembled by his widow Ann Druyan. (Post about it here.)
This book is a collection of essays on various topics, many, the author acknowledges, based on shorter essays written for Parade magazine. This is an interesting point for a couple reasons. Parade is a Sunday supplement magazine that’s been distributed to newspapers in the US for decades, and so its topics have always been light. Also because these days, as I see it inside the San Francisco Chronicle, it’s very thin, mostly full of ads and clickbait-like lists of recipes or celebrity factoids (and a quarter page single Q&A by Marilyn Vos Savant), with no essays even approaching a 10th the length of Sagan’s essays in this book. Parade in the 1980s and ‘90s, when most of these essays were first published, must have been quite different.

Financial Times: Yuval Noah Harari on Lessons from a year of Covid, Feb 25th.
How can we summarise the Covid year from a broad historical perspective? Many people believe that the terrible toll coronavirus has taken demonstrates humanity’s helplessness in the face of nature’s might. In fact, 2020 has shown that humanity is far from helpless. Epidemics are no longer uncontrollable forces of nature. Science has turned them into a manageable challenge.
Like the hierarchy of morality (discussed here), this one is not mine. It’s an idea first proposed by psychologist Abraham Maslow in 1943. Wikipedia has this entry about it. It runs like this, from the most basic:
NYT, 3 March, Nicholas Kistoff: How to Reach People Who Are Wrong, subtitled, In the post-Trump era, research suggests the best ways to win people over.
A fine essay, that keys off Adam Grant’s new book THINK AGAIN, which I have sitting here in my to-be-read-soon stack.
The main points of this essay (and apparently of Grant’s book) are familiar from some of my recent provisional conclusions. It’s about intellectual humility, and how the world is not black and white.
This is the fifth of Heinlein’s so-called “juveniles,” what would be called YA (young adult) books today, that Heinlein published from the late 1940s to the early 1960s. I posted about the second of them, SPACE CADET, here last year, but have been negligent about the others. It wasn’t until rereading these books (there are 13 or 14 of them) in chronological order in recent months that I noticed they proceed in outward progression from Earth. The first half are set on Earth and the Moon, then in interplanetary space, then Mars, then Jupiter’s moon Ganymede, and then, with this book, Earth, a large space station orbiting Earth, Venus (for most of the book), and finally Mars. The latter books are mostly set in interstellar space, i.e. planets in other solar system, except for the last one, PODKYANE OF MARS, as the title indicates.

Here is a middle-period book by the Oxford scientist whose writing mostly focuses on evolution; this one is an exception. Its topic is the beauty of science, how science addresses the “appetite for wonder,” and how people who don’t understand science pursue delusions in search of that same sense. It’s a very good book if somewhat uneven; some chapters are crystal clear and insightful; others get bogged down in very specific examples of biological systems that the author is no doubt familiar with but are difficult for layman (at least for me) to follow.
Half-way through Dawkins quotes Carl Sagan, with a passage the represents the key theme of the book:
How is it that hardly any major religion has looked at science and concluded, ‘This is better than we thought! The universe is much bigger than our prophets said, grander, more subtle, more elegant? Instead they say, ‘No, no, no! My god is a little god, and I want him to stay that way.’ A religion, old or new, that stressed the magnificence of the Universe as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths.
