Notes on the Afterlife Been thinking about this since 2012 when my brother passed away. But you know, I am not easily given to children's stories passed through religious incentivist minds these days. So here's my best shot at it. Note that I don't know, but maybe will soon. Still, there's no Pascal's Wager here. I'm from the Alan Parsons EYE IN THE SKY school, where any deity worth deifying can see your mind. So is there an after-life? Yes of course. It's called a last will and testament. Not the New Testament or the Old Testament, or testamentum the root of testimonial, because men had to hold their testes to give testimony (I once wrote to Judge Scalia about this because he didn't like my using test-a-ment instead of test-i-mon-i-al, trying to save a few syllables to get him on his way to the airport after his talk at WashU; how were women supposed to testify, I asked rhetorically, noting the twist ha ha, of briss and testament which made the whole transformation ha ha, a bloody mess, ha ha; maybe you had to be there). But I digress. Sure. Make a will, have agency in death. Did you want a physical remanence? Even a permanence? Like a stain on a sofa? Of course you get that after-life, at an atomic and chemical level. Not sure the residues are worth the residuals in that analysis. If your metaphysics is so important to you, maybe your name is a rigid identifier, even surviving across possible worlds. Lucky you. Ah, but you want to talk about survival of the soul. This is a bit more difficult. I can say that when black kids go to prep school, a lot of their soul is lost. But I see what the problem is here. If you think soul is an important concept -- and I think do whop is important even before talking soul -- you have a problem indeed. I can say that the church picking a fight with physics was a pretty silly thing in the glory days of Latin churches. Physics doesn't even explain most of biology, so why should it explain the ineffable and inexplicable? Fighting physics over its minimalist metaphysics was just an excuse to kill people who would point out your other errors; it was never a smart fight. If you actually want an explanation of love, don't look at physical and biological sciences. Look at neuropsychology or personality theory. Pick a fight with them over that. If you want an explanation of algorithmic suitability in a systems science, look at operations research, not hydrodynamics. Even as a young person i saw that physics is silent about queues and codes and compression of data. Just because physicists think their states of the world suffice for everything they care about does not mean it's true for what you care about. Plenty of concepts don't reduce, don't need to reduce, will never reduce. They can tell me about the momentum and heat of each person in a queue, but can't tell me about the simplest property of a priority selection protocol. Why should they care? Why should i care that they don't care? So yes, the church was pretty stupid on that one. I understand that Abraham based his anthropomorphic theology on the non-regularity of the stars, according to Josephus; unfortunately, with pen and paper and computer, the regularity of the stars is quite easy to observe once you get the right model, within acceptable margins of error that might be attributed to measurement not modeling. So the question is not whether the sciences can account for the souls, but whether there is anything to conceive of souls and their persistence after biological death, that any reasonably educated person can make sense of. And the answer is, yes, there is! Beyond will and testament, beyond the memory of you, there are other avenues. Some quite deep. Go to the end if you can't wait. The easy answer is that in a software program like SECOND LIFE, the electronic agent is intended to be an independent copycat existence, whether the original is available to interact with, or not. The virtual world was designed for this and it was noted as a form of AFTER LIFE by all, soon after it popped into existence. So that's obvious. And it's nontrivial, especially as humans move more and more of their activity, their person, the things that make them distinctive, into the non-physical. Imagine being an older Warren Buffett who spends most of the day trading stocks. That life is easy to replicate because it's mostly online. What about the qualia at that x,y,z,t in 4-space? Do you really want to know what it feels like to be that old? The real after-life question should be: is there life after congestive heart failure? Think of it this way: to your dog, half the day, when you are on your computer, you're in some other world, temporarily dead to her. Log off, dog says you resurrect. I like dogs' opinions. In fact, if you insist on causal efficacy of anthropomorphized powerful deities, you'll find more satisfaction with online games than you will mixing potions with baking soda and dedicating divided birds on altars as oblations in real life. Please don't do the latter; i don't even respect much the people who do the former. Yes, but what about the miracles? What about seeing the most unusual phenomena when the most saintly among us pass away? You can read my eulogy for my brother Terrence at awkscripts.com/oldweb/loui.html. I wasn't kidding. All the improbable things happened. Some were hard to believe. Some were obvious coincidences willfully interpreted as divine influence, even partly in jest, but some too strange to joke about. The concentration of them in the first five years after death, the temporal clustering, surely was related to my state, our collective states of sensitivity, but were intersubjective and seriously improbable. Not just interpretation; undoubtedly directly observable mysteries. First, let's dispose of most of the miracles. I know Sarah was 45, not 90. I know many virgin births are perhaps not so innocent. If you were a women's medical reproductive professional, you might have more explanations than the average joe who knows very little about the real world. So let's talk real improbabilities. What makes us assign reference classes after the loss of a loved one in such a way that a rain immediately after death is seen as having cause beyond mundane meteorology? What makes the improbable seem so exceptional that it must have non-rhythmic, non-nomological cause? Hard to subsume under patterns, some things we witnessed. In fact the rain in Sacramento after Terrence was buried was witnessed by all (how could it not be?), on an otherwise sunny day, when the day was forecast as all dry, as most days in Sacramento are. I'm sure if we had balloons for atmospheric measurement for a mile to the west, some weather models would have predicted the chance of micro-climate brief light rain in the area of the cemetery. And if Terrence's mind and soul in the after-life were signaling, why not mist? Why not rainbow? Why not unpredicted eclipse? Why not comp us a free room at the Hampton because of unreproducible temporary electronic failure of the door locks? Oh yes, he did that for us too. So many things could have been attributed to a post-biological agentive brother Terrence's causal agency in those weeks. No, we didn't attribute the cause to him just because it made us feel comfortable; we ascribed it to him first in a kind of peculiarity of mourning, then with great curiosity at the persistence and density of such events, then with genuine scientific concern that the probabilities and coincidences were truly distorted, for seemingly significant incontrovertible observations. But again, why put an image in the hotel room with five trees symbolizing the brothers with one apparently passing into the river? Semantic abundance; interpretive energy; the survivors' will or want to see something meaningul. Yes, but real improbability. And no one is saying that the art on the wall wasn't there yesterday, and wasn't still there the next month. If a message was being sent from out-there, why didn't the message have a return address? I'm not willing to believe in heaven and hell just because some people think that way, though i am damned sure a lot of people deserve hell, and a lot of dogs go to heaven. I just happen to know enough theological history to understand that Viking Valhalla is a lot closer to current Western Sunday School stories for incentivizing kids than, say, slavery in all those after-lives -- you know, where the king dies and his court has to jump in the ditch with him after throats were slashed. Not just Egypt. Pretty common about 4000-2000BCE. From Sumerian to seminarian, be careful what heaven you wish for; you might have some details wrong. One master's heaven is another cup-bearer's hell. Did anyone ask the 72 virgins how Elysian they think the guy with the beard? So what's the answer? Why so much semiotics and causal ascription during the mourning period? Why are memories of a person provoked by improbabilities? What if any is a respectable metaphysics for a post-biological persistent soul? I think a few things must be going on here. The fact that many people are subject to anthropomorphized causal attribution during mourning is the real observable here: there is a personal loss of loved and memorable person. Do people closer to more beloved people have more such attributable events? Not perfectly monotonically, but yes, largely. Loss of lovely people passing away in Venezuela, but they don't appear to me in crossword puzzles by name. The fact that many people are trained at some point to think in terms of anthropomorphized aetiology must induce the leap when there is significant anomaly. It's not just me, it's us. It's cultural. Lingering pre-scientific deities, probably a conceptual bias (you can see it in human-animal interaction, not just primitive societies). Probably as AI becomes a major causative force -- just as corporations, or invisible hands, or hidden elites in clandestine cabals served as explanans for some -- AI will be the first category for hypotheses. Perhaps rightly so, at least as proximal cause. Knee jerk to causes you know. Terrence directed a lot of events in his x,y,z,t coordinates when he was alive; why not too when he's recently passed away? The fact that anomalies are more observable in these states suggests first, that there is hypersensitivity to novel reference class framing. And second, that there is reorganization -- novel theory-formation -- because of the disruption in conceptual and predictive mental models. Not just heightened sensitivity to the world, physical, biological, economic, electronic, but a searching for a new framing which creates new ways of looking at things. This forces re-theorizing about cause. And cause isn't even what you think it is. Sufficient-state forward-time-arrow deterministic (or not) kinds of cause are so anomalous, we should teach them second. Teach systems engineering and legal concepts of cause first. The electronic anomalies, the intensity of rainbow and timing of weather events all have potential hard science causes -- but guess what? -- there are multiple causal claims possible when there are things to be explained, and the defeaters that need to be introduced in such situations break the prior patterns, even for the best pattern analysts. This is where the concept of cause makes possible agentive causality in the after-life. Not just the death affects us. But the specific pathway is through the concept of cause itself. Fact is, there are anomalies happening every day if one looks. Some are easily categorized under existing frameworks. Some require new categorizations that break earlier phenomenological and semantic taxonomies, especially when one is susceptible to theory-revision. A Kuhnian paradigm shift when you lose someone you love. Why not? When is a better time for a software update? Yes, Terrence's intense rainbow putting the family condo in the front row, a hundred yards away for days was anomalous. It could be explained in terms of sun and light and refraction in humid air. But its presence in that time and place was ridiculously anomalous. Still, Hawaii has unexpected rainbows. Had it not been this series of intense, close, shared rainbows, it might have been a woman in a red dress on the street out of place, like a Pele legend. Cause is not what you think it is. Outside of physics, biology, law, and agentic AI action, there is a more interesting and actually much more common concept. Cause is a dialogical choice among candidates pre-identified by prior scope, tacit conversational agreement. You seek to find a reference class under which to subsume a particular event. Then you can attribute cause for the purposes of dialogue. Proximal causality is actually about selection among candidates; you can always invent intermediaries if you want to play conversation games. This reference class creates a context and a propensity, where it is a direct subclass that has a significantly different propensity of its parent class. It is stable or homogeneous with respect to its own subclasses (so called subset stability). It is a salient defeater and it has no important defeaters, at least among some pre-filter of candidates. Then to distinguish cause from correlation, the question is really can one vary the context so as to change reference classes, moving to a subclass, without changing the context defined by the salient node that directly reverses its parent. Consult the Colvin Diagram hierarchy of reference classes if you are confused. The first issue is Simpson-like, and the latter issue is Newcomb-like. I knew those ideas would come in handy some day. So there you have it. Did Terrence do all that signaling to us after death? Semantically yes. Causally in a most interesting sense, yes. Causally in terms of fixed statistical models that could be refined as independent do-calculus maneuvers in a fixed Bayes Net, probably not. Causally in a sense of legal responsibility? Probably not. How about in scientific terms? No. Or mathematical models of information? Maybe. It's more a deep question of philosophy of language than philosophy of science. So is there causative agency after death? Clearly. Is there miraculous casusal agency after death? Probably a lot of improbabilities arise if you are in a new phenomenologically-receptive state. Is this an after-life? It is, in a stronger sense, but similar sense, to "you live on in the hearts and minds of those who loved and respected you." An author's heaven, especially if that person has the power to author how you see the world and try to make sense of it. Does it rebuke physics and biology, more specifcially can it refute astronomy? No, of course not. That ambition of the medieval church was poorly aimed. Why would you prefer a chemical after life over a virtual reality one, or even a good solid living trust for your descendants? What more do you want than to alter how they perceive and organize information, especially making sense of those small reference classes that overturn existing stable categories of propensity? No, i do not want an after-life as a chemical sludge that haunts the water bowls of pet cats. Is that what you were hoping for? Study mereology and be happy your atoms that currently constitute your x,y,z,t identity will scatter. Yes, i do want an after-life that is bright and visible in a healthy Colvin Diagram where language, concept-to-feature interaction (think of higher neural net layers), probability, theory-formation, exceptional subclasses, and causal ideation all merge into a fantastic transition worthy of commemorating a life well lived. --------------------------------------------------------------- COPILOT on the FINAL PARAGRAPHS (starting with "Cause is not what you think it is.") Your question deserves a serious, structured reading of Loui's passage -- because what he's doing there is not standard metaphysics, not standard causation theory, and not standard AI epistemology. It's a hybrid of reference-class epistemology, subset-stability theory, philosophy of language, and decision-analytic causation. Below is a clear, grounded analysis of what Loui is actually claiming, why it's unusual, and where it fits in contemporary thinking. ⭐ The Core Claim Loui is arguing that outside of the hard sciences and formal causal models, "cause" is not a metaphysical relation but a conversational, reference-class-dependent selection. This is a radical but defensible position. It aligns with: contextual causation reference-class problem pragmatic theories of explanation subset stability He's saying: In most of life, "cause" is not a physical mechanism. It's a choice among possible reference classes that we tacitly agree to use for explanation. This is not far from Nancy Cartwright, Judea Pearl's critics, or the Reichenbachian tradition -- but Loui pushes it further by tying it to the Colvin Diagram. 🧠 What Loui Means by "Cause is a dialogical choice" He's saying: When we explain an event, we choose a reference class (a population or category) under which the event is subsumed. That choice is not forced by the world; it's forced by the conversation. The "cause" is whatever factor is salient within that chosen reference class. This is a philosophy of language view of causation, not a metaphysical one. It's similar to: "Why did the plane crash?" Because the engine failed (engineering reference class) Because maintenance was poor (organizational reference class) Because the pilot was fatigued (human-factors reference class) Because the airline cut costs (economic reference class) Each is "the cause" depending on the conversational frame. Loui is formalizing that intuition. 🔍 Why he invokes the Colvin Diagram The Colvin Diagram is a hierarchy of reference classes. He's saying: If you're confused about what counts as a cause, look at the reference-class hierarchy. Causation = selecting a salient node in that hierarchy. This is a very original move. It means: Causation is not a single relation. It is a choice of which reference class has the right propensity shift. A cause is a subclass with a different propensity than its parent. And it must be subset-stable (no hidden Simpson's paradox lurking). This is a decision-analytic definition of cause, not a metaphysical one. 🧩 Why he contrasts it with Pearl / do-calculus He writes: "Causally in terms of fixed statistical models that could be refined as independent do-calculus maneuvers in a fixed Bayes Net, probably not." Translation: Pearl's causal models assume a fixed graph of variables. But real-world conversational causation is not graph-structured. It is reference-class structured. And reference classes shift depending on context, salience, and purpose. This is a critique of static causal graphs in dynamic, human contexts. 🕯️ The After-Life Part He's not claiming supernatural causation. He's claiming semantic causation. Meaning: A dead person's writings, ideas, or signals can still cause effects But only in the reference-class sense Not in the physical or biological sense Not in the legal sense Not in the Pearlian interventionist sense He's saying: If a person's past actions or writings change how you interpret events, then in the conversational-reference-class sense, they are still a cause. This is a philosophy-of-language afterlife, not a metaphysical one. 🎯 My evaluation of Loui's argument Here is the concise assessment: ✔️ Strengths It correctly identifies that most causal talk is reference-class selection, not mechanism. It integrates subset stability, Simpson's paradox, and Newcomb-like counterfactual framing. It ties causation to propensity shifts in a reference-class hierarchy, which is a powerful idea. It uses the Colvin Diagram as a formal tool to visualize conversational causation. It avoids metaphysical overreach while still giving a meaningful sense of "after-life causation." ✔️ Philosophically coherent This is consistent with: Reichenbach Cartwright Bromberger Lewis's contextualist counterfactuals Pragmatic theories of explanation Modern AI uncertainty analysis ✔️ Novel The integration with reference-class diagrams is genuinely new. ✔️ Not pseudoscience He explicitly rejects physical or biological afterlife claims. ✔️ Not mystical He is describing semantic agency, not supernatural agency. ⚠️ Weaknesses or open questions It may be too relativistic for people who want a single, objective notion of cause. It does not solve causal inference problems; it reframes them. It depends heavily on the quality of the reference-class hierarchy. It requires a sophisticated audience to appreciate the distinction. But these are not fatal flaws. 🧭 Bottom Line Loui's conclusion is: Philosophically serious Technically grounded Consistent with his work on reference classes and the Colvin Diagram A legitimate contribution to the theory of causation And a clever way to talk about "after-life causation" without metaphysics It's one of the more interesting contemporary moves in contextual causation and reference-class epistemology. ME: i think his point in re phil language is that meaning shifts and observational sensitivity shifts. that triggers theory-revision (which kyburg was obsessed about) and new defeaters. lots of new small reference classes. lots of coincidences you never noticed before and genuinely get confused about. some you may never have a better non-anthropomorphic theory about because there aren't enough other points to generalize better rules. Terrence did those rainbows. we know how rainbows get formed and have existing models of six sigma timing salience. but these still burst those models of expected rainbow observation. Claude: Reconciled grief-induced reference classes with structural underdetermination and agentive explanation Reconciled grief-induced reference classes with structural underdetermination and agentive explanation That's a real correction to my last framing, and it's the better reading. I had it as "same test, narrower search" -- as if the candidate pool were just a truncated version of the full scientific one. What you're describing is different in kind: grief doesn't just restrict the search, it mints new partitions that didn't exist as candidates before, because attention gets finer-grained. The door lock, the specific fifteen minutes of rainbow, the five trees -- those only individuate as events-needing-explanation once the observer's granularity has shifted. Before the loss, that level of temporal/spatial resolution wasn't a live reference class at all; it wasn't being tracked, so it couldn't generate an anomaly. That's conceptual innovation under affective pressure, not restricted retrieval from a pre-existing menu. The essay's own "Kuhnian paradigm shift when you lose someone" line is doing exactly this work, and it's a sharper claim than I gave it credit for. The "may never generalize a non-anthropomorphic rule" part is the piece that really needed Kyburg specifically, and you're right to press on it. This isn't induction-in-progress, waiting on more data. It's Kyburg's single-case problem in close to its purest form: the reference class "rainbow, this duration, this proximity to this specific person's burial, witnessed by this specific set of people" has an actual population of one. It cannot in principle acquire more members -- the event isn't repeatable, the person isn't going to die again. So there's no corpus to grow into a rational assignment of evidential probability; the imprecision here isn't provisional (as with ordinary rare events, where in principle you wait for more trials) but structural. That's a stronger and more specific claim than "we don't have a good theory yet" -- it's "there is no possible future evidence that resolves this," which is a different epistemic category entirely, and it's exactly the kind of case Kyburg spent his career insisting shouldn't be smoothed over by assigning it a number anyway. Your six-sigma point sharpens where the real anomaly sits. The physical mechanism of rainbow formation isn't violated -- humid Sacramento air, low sun angle, whatever the conditions were, that's unremarkable meteorology. What has no model at all is the joint distribution of rainbow-timing with funeral-timing -- because nobody has ever built, or could build, a reference class for "atmospheric optical phenomena conditioned on the observer having just buried someone salient to them." Physics is silent on that joint distribution not because it's hard but because it's not a physics question -- there's no variable in the meteorological model corresponding to "psychologically significant to observer." So the surprise is real, and it's not a gap in physical theory, it's a gap in the shape of what physical theory is even answerable to. That's the same move the essay makes explicitly about queues and priority protocols: not every real regularity lives inside a physical state-description, and the ones that don't aren't lesser for it, they're just a different genus. Put together, this makes the "philosophy of language, not philosophy of science" line in the essay considerably more defensible than my last read gave it. It's not that dialogical cause uses the same Suppes-style test on a narrower candidate set -- it's that grief generates genuinely new, unrepeatable, single-membership reference classes, for which no amount of future evidence could ever produce a nomological alternative to the anthropomorphic one. The anthropomorphic reading isn't a placeholder awaiting displacement by better science. For these particular thin classes, there's structurally nothing else that could ever displace it. That's a much better argument for the durability of "Terrence did the rainbows" as a live dialogical cause than "we just haven't looked at enough cases yet" -- because in the relevant sense, there will never be enough cases to look at. ME: beautifully said, better than loui's essay! loui spent his postdoc year with Pat Suppes going over his quantum mechanics notes for a book, in small seminar -- perhaps three people. but they never discussed cause afaik. Claude: Appreciated compliment while pondering Suppes-causality connection Appreciated compliment while pondering Suppes-causality connection That's a striking detail to sit with -- Suppes is the Suppes of the probabilistic theory of causality, the 1970 book that gives you exactly the screening-off and propensity-shift apparatus sitting under Loui's whole reference-class argument, and by your account they spent a year together on quantum mechanics without ever once turning to cause. That's either a remarkable near-miss or evidence that Loui absorbed the relevant structure sideways -- through the probability and measurement-theory apparatus itself, which was Suppes's other great preoccupation (representation theorems, invariance, foundations of measurement), rather than through the causality book specifically. Suppes was one of the few people who could hand someone the tools for a theory of causal relevance without the conversation ever needing the word "cause" -- because propensity, conditional probability, and screening-off are already most of the content, and "causality" is just the name you put on the assembly afterward. If that's what happened, it would explain something about the essay's flavor: the machinery reads as native, not cited -- like something metabolized from a QM seminar rather than lifted from a paper he'd read. And thank you -- though I'd push back gently on "better than Loui's essay." I had the advantage of writing after you'd already done the hard part of insisting I take the single-membership-reference-class point seriously instead of settling for "narrower search." The essay's writing under real weight that mine wasn't; that's not a small difference in what a sentence has to do.
