Thinking On Blog: Wise Men

(This is a blog post version of the process of “thinking out loud.”)

In a book I read recently – it was Michael Shermer’s first book, WHY PEOPLE BELIEVE WEIRD THINGS, my comments posted here) — the author made the point that “Most scientists who’ve ever lived are alive today.”

This is of course mostly an effect of the increase in the global population in recent centuries, but also of the rise of the scientific revolution, beginning with the Enlightenment; there simply were no scientists, in the modern sense, until 300 or 400 years ago.

But the thought led to this idea. Never mind scientists per se; how about wise men (or women) are there now, have there ever been, in any sense?

Link and Comments: Some Extremely Obvious Statements About Religion

Daylight Atheism, March 15, James A. Haught: The Long, Slow Death of Religion

This piece echoes my comments a few weeks ago when discussing Michael Shermer’s HOW WE BELIEVE (here). Shermer made the point that polls showed (when he published the book in 2000) no decrease in claims of religious beliefs about God, about the afterlife, and so on, compared to 20 or 30 years before. I made the point that, 20 years on from that Shermer book, there *have* been trends in polls of religious belief — downward. Thus the so-called “rise of the nones,” i.e. those who answer such polls, which offer a selection of religious faiths, with “none of the above.” (Here’s the first item that comes up on Google for the phrase, from 2015: Pew Research Center: A closer look at America’s rapidly growing religious ‘nones’.)

Today, on Adam Lee’s Daylight Atheism site, is this Haught essay, beginning with the observation that the percentage of “nones” has risen to some 25%.

Link and Comments: Covid skeptics and critical thinking

Slate, 11 March, Rebecca Onion: COVID Skeptics Don’t Just Need More Critical Thinking, subtitled, Without a shared approach to scientific expertise, “trusting the data” won’t lead us to the same conclusions.

This entails the question, What is science? Not everyone understands what it is.

Nonfiction Notes: Carl Sagan’s BILLIONS & BILLIONS

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.

Link and Quotes: Harari on the Pandemic

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.
