In 1917, three children in Fatima, Portugal claimed to have seen the Virgin Mary. They promised she would perform a miracle on a certain day in October. Nearly 100,000 pilgrims arrived, hoping to see whatever happened, and nearly all report that the sun turned pale, changed color, and spun around. Many other writers have investigated the children and their visions, but I was fixated on this sun miracle. Despite popular discussion of "mass hallucinations", this is AFAICT the only example of tens thousands of people all saying they witnessed the same impossible thing, at the same time. I got kind of obsessed with this; you can read my preliminary investigations in this, this, and this post. One of the first things I found was that there were many other sun miracles - at least ten! - similar to Fatima. Most were associated with Marian apparitions, but one was at a Buddhist temple. Bigfoot only gets sighted by lone hikers; ghosts are only ever in the corner of your eye; UFOs are just blurs in the sky. Of all the countries and outposts in the vast empire of the unexplained, it's only this one phenomenon - the spinning, multicolored sun - that regularly gets seen by thousands of people at once, in broad daylight. Speaking of "regularly", there's one spot where it continues even today. Fifty years ago, the Virgin Mary appeared to six children in Medjugorje, Bosnia. Now those children are well past middle-age, but she continues to come. Three of them report that she's appeared less frequently as the years go by, but the others still see her every day at 6:40 sharp. Travelers to Medjugorje, especially those passing through around 6:40, report a slew of miracles, including the spinning sun. Certainly this is true of those whose hearts are pure. But even the atheists get lucky sometimes. I was shocked never to have heard about this before. There's a place you can just go, and have a decent chance of seeing a real miracle? People take vacations to the Bahamas for the beaches, when they could go instead to Medjugorje and see the natural law of the universe get violated in real time? Seems crazy! So in early April, I and my extremely-accommodating, long-suffering wife flew to Dubrovnik, rented a car, and drove down a series of windy mountain roads toward the Bosnian border, hoping for a miracle. https://www.astralcodexten.com/p/waiting-for-the-miracle

Finalist #8 in the Book Review Contest This is one of the finalists in the 2026 book review contest, written by an ACX reader who will remain anonymous until after voting is done. I'll be posting about one of these a week for several months. When you've read them all, I'll ask you to vote for a favorite, so remember which ones you liked] [Content warning: Sexual and relationship practices from a thousand years ago, from a time and place with a very different morality than what you probably subscribe to.] The past is an alien civilisation Around the year 1000, the Imperial Court of Japan in Kyoto was a world of opulence, aesthetics, and ambition. Isolated from the lives of regular commoners, every aspect of the lives of the elite were governed by complex etiquette rules, and relationships were thoroughly intertwined with politics and the ambition for power and wealth. High-ranking women and men lived lives so separate that they might have a passionate love affair without properly seeing each other's faces. It was in this world that Murasaki Shikibu, an intelligent and educated lady in Empress Shōshi's court, wrote The Tale of Genji, which is widely considered to be the world's oldest novel. It is an extraordinary masterpiece and a highly questionable soap opera, and I've never read anything like it. https://www.astralcodexten.com/p/your-book-review-the-tale-of-genji
I am Daniel Böttger1. In 2023, my review of On The Marble Cliffs took second in the ACX book review contest, and Scott offered me the right to pitch him more essays. I have worked as a neuroscientist, so in 2024 I pitched a post with my theory of consciousness. Later that year, my connection to neuroscience took an unexpected turn, and I wrote about my experience getting diagnosed with brain cancer. This post is an update on how I'm doing. I'm doing well. Very well, in fact. Suspiciously well. So well that the only other person I've ever heard of doing as well as I am was Jo Cameron, who was profiled on ACX for her rare genetic mutation that makes her incapable of negative emotion. My case can't be a mutation, so it must be related to my brain cancer and subsequent surgery. I write about it here in the hopes of making a novel contribution to the study of low-suffering phenotypes. Content warning: the first part of this review contains medical details that some people might find gruesome; I am bad at judging these things since I can no longer feel disgust or fear myself, and have tried to err on the side of completeness. https://www.astralcodexten.com/p/absurd-adventure-and-amygdalectomy
I. Econblogger Nicholas Decker is not a fan of AI 2040: One of the centerpieces of AI 2040 is the proposal that we pause the development of AI at a high level, use the AI to research alignment, and only then proceed. I am skeptical of this, and not only because it seems impractical to get such cooperation. My first argument is that I do not believe a period of "researching alignment" is meaningful – alignment research is simply capabilities research, patching particular bugs in the system, and we're not going to find anything deep without actually being in contact with the systems […] I envision AI alignment as being like research into aviation safety. There is no grand theory of why airplanes crash, unless you take that to mean gravity. Instead, we patch little problems. The airplane crashed because of metal fatigue in the engine – okay, we mandate inspections of engines, and prevent crashes from occurring by that source. As new problems arise, we iterate. We don't even need for there to be a crash to make improvements – we test proactively, we build in redundancy, and we monitor for deviations which could be a threat. What we are not doing is thinking about how we are going to keep flying saucers from crashing. If flying saucers are invented, then we will work to keep them from crashing, but we will use exactly the same methods. We will test them, see how they perform, and patch particular problems. AI will be the same way […] We should expect alignment to happen by default. My challenge for Nicholas is: would this work on you? https://www.astralcodexten.com/p/nicholas-decker-in-hell

[Original post: Why I'm Staying Out Of The Substack Religion Debate] Ben Smith writes: This post sure reads like participating in the object level debate, not just "writing a post about how I won't participate". I did joke about this at the end, but I also want to defend calling this a post about how I won't participate. This essay presented a kind of hand-wavey heuristic for why I'm not spending lots of time examining the details of every individual argument. This is fine, everyone has to do this or be overwhelmed, but I think it's important to keep hand-wavey heuristics for not participating in arguments, vs. actual participation in arguments, distinct. Little annoys me more than when I spend weeks carefully gathering citations and making a substantive contribution in a domain, and somebody responds with "well that's obviously all bullshit because it vaguely reminds me of something I have negative affect towards". It's not necessarily wrong to deprioritize a topic because it vaguely reminds you of something that you have negative affect toward, but I would prefer these people admit they're dismissing/ignoring it rather than claim to be engaging with it. I'm working on a longer post about this topic. https://www.astralcodexten.com/p/highlights-from-the-comments-on-the-491
