Super-earth life

 
Given that "super-earths" with masses twice to three times that of the earth appear to be common in the habitable zones, I would be inclined to imagine advanced life on such worlds as being squat with either lots of legs or very thick short ones. Maybe a cylindrical body about a meter or so thick and a couple meters in diameter, a few centimeters above the ground with hundreds of little feet, equipped with various orifices and tentacles and sensory projections.  

We evolved from arboreal creatures and so have opposable thumbs and color stereoscopic vision and a basic vertical orientation.  More massive planets probably wouldn't offer such an environment.
Reconciled gravity scaling with alternative body plans and sensory evolution

A few things worth pressure-testing in that picture, since the mass range you're citing does more subtle work than it first appears.

The key uncertainty is that "twice to three times Earth's mass" doesn't map cleanly onto surface gravity. Rocky planet radius scales roughly as mass^0.27 (mass-radius relations flatten out because increased pressure compresses the interior), so a 2-3 Earth-mass rocky world isn't 2-3x the radius — it's maybe 1.2-1.3x. Surface gravity (proportional to M/R²) then comes out closer to 1.3-1.6g, not the crushing multiple you might picture from the mass figure alone. That's a meaningfully different biomechanical problem than what your image implies. A super-Earth could also turn out to be a low-density "mini-Neptune" with a thick H/He envelope rather than a scaled-up rocky Earth, or a water world — composition matters as much as mass for what the surface (if there is one) is even like.

That said, even 1.3-1.6g is a real constraint, and your intuition about the general direction is sound. Column-like or wide-based body plans do get more attractive as g rises, because bending and buckling loads on a vertical structure scale with weight while cross-sectional load-bearing capacity scales with area — the classic square-cube penalty. Trees on Earth are already close to their gravitational buckling limit (there's research suggesting redwood height is capped partly by hydraulic limits and partly by mechanical ones); push g up 30-60% and tall vertical plant analogs get harder, though not impossible — you'd expect shorter, thicker-trunked, more heavily buttressed growth forms rather than the total absence of height.

For the animal side, more legs and a lower center of mass are a completely sensible response to higher effective weight — it's the same logic that makes elephants columnar-legged rather than gracile, just extended further. But it's not the only viable solution. You could also get:

    Sprawling, low quadrupeds/hexapods rather than a true many-legged cylinder — wider stance, shorter limbs, but not radically more limbs, since adding legs has its own control-system and metabolic overhead.
    Aquatic or semi-aquatic bias — buoyancy neutralizes gravity almost entirely, so if the higher-gravity hypothesis holds, you'd expect intelligence and complex life to be more likely to originate or remain in water on such worlds, sidestepping the whole structural problem.
    Smaller-bodied fauna generally — since gravity's penalty is worse for large animals (mass scales with volume, support scales with area), a straightforward response is organisms simply staying smaller across the board rather than solving the problem architecturally.

On the arboreal-precursor point: I'd separate two things you've bundled — manipulation and verticality. Grasping/manipulation doesn't require an arboreal ancestry or opposable thumbs specifically; octopus arms, elephant trunks, and your tentacle idea all show it's achievable from very different starting niches, including ground-dwelling ones. So I wouldn't assume a squat, ground-hugging body plan forecloses fine manipulation — tentacles or trunk-like appendages could do that job perfectly well without any arboreal history. Verticality (standing upright, freeing forelimbs) is more genuinely tied to your arboreal-descent story, and that does look less likely to reoccur under higher gravity, for the buckling reasons above.

So: I think your core mechanical intuition — shorter, wider, more heavily supported body plans on higher-g worlds — is well-grounded in actual scaling physics, not just aesthetic extrapolation. Where I'd push back is the assumption that "super-Earth" reliably means "high gravity" at all, and I'd hold the many-legged cylinder as one plausible solution among several rather than the default outcome.

Thanks for the detail on scaling/planetary diameter.  The main point is don't expect giraffes.
Calibrated tone to match conversational wit over formality

Fair enough — and that's a good compact way to put it. No giraffes, no basketball players, probably no herons balancing on one leg. The whole "tall, thin, spindly" body plan is a bet that gravity lets you get away with a slender high center of mass, and that's the bet that gets called on a higher-g world.

What you'd expect instead is something more like the existing spread of Earth's low, broad-based body plans — tortoises, hippos, rhinos, crocodilians — becoming the norm rather than the exception, with the slender/vertical end of the distribution (giraffes, herons, humans standing bipedally) trimmed off. Not necessarily converging on one exotic solution, just the whole design space shifted toward squat and wide.

That's a nicely falsifiable-sounding principle for whatever you're writing, incidentally — "no giraffes" is the kind of clean heuristic that survives contact with harder biomechanics questions even if the details of which squat form wins stay open.

I like something roughly circular, disklike, maybe a meter thick and a few inches off the ground, held up by lots of little feet, a mass with lots of projections: sense organs, communication organs, manipulation organs.
Examined mechanical viability and evolutionary constraints of disk design

That's a nice refinement — you've basically converged on something between a chiton, a horseshoe crab, and a millipede that's been flattened and scaled up, with the vertical dimension almost eliminated. A few things about the design that are worth thinking through, because they cut both ways:

What works well mechanically: A disk is close to the ideal shape for a high-gravity world. Weight is distributed across the widest possible base, center of mass is essentially at ground level, and "lots of little feet" spreads load so no single point of contact bears much force — similar to how snowshoes or caterpillar treads work. You also sidestep the bending-moment problem entirely, since there's no cantilevered structure sticking up to buckle.

The problem you'll need to solve: what's inside a meter-thick disk. This is actually the more interesting constraint, and it's a real one, not a nitpick. A meter of tissue is a lot of volume relative to the surface area available for gas exchange, waste removal, and (if applicable) thermoregulation. Earth solved this with lungs, gills, and circulatory systems that create enormous internal surface area — but those evolved for compact or elongated bodies, not a squat disk. You'd likely need either: a system of radiating internal channels or sinuses bringing the surface in in a folded/branching way (root-like), or a much lower metabolic rate than Earth animals of similar mass, or a body that's mostly non-metabolically-active structural material (like a shell or cartilage matrix) with the "living" tissue concentrated in a thinner active layer near the surface or perimeter.

Symmetry and "facing": Truly circular/radial symmetry is common in sessile or slow-drifting organisms (jellyfish, sea urchins, sand dollars — your disk resembles a sand dollar that got up and started walking) but rare in mobile organisms that need a consistent direction of travel, because you generally want sensory concentration facing the direction of motion. If it moves in any preferred direction at all, you'd expect either a secondary bilateral asymmetry laid over the radial base plan (denser sensory projections on a "leading" arc), or genuinely omnidirectional movement with sensors evenly distributed and no fixed front — which is stranger and more interesting, honestly, and would have big implications for how such a creature experiences space and organizes cognition, since it wouldn't have our forward/backward asymmetric spatial framework at all.

Nervous system: Hundreds of small feet moving in coordinated waves is very achievable — it's what millipedes and centipedes already do via distributed ganglia with local pattern generators, no strong central brain required for the motor pattern itself. But higher cognition sitting on top of that plan raises a real question: do you centralize processing in one hub (risking a single point of failure and long signal-transit times across a meter-plus disk), or keep it distributed with something more like a mesh/consensus architecture? The latter is a genuinely different flavor of mind than anything vertebrate, and might be the more alien and compelling choice if you want the psychology to feel non-human rather than just the body.

That last point might be the most fun lever you have — the body plan pushes you toward a decentralized nervous system almost as a corollary, and that opens up a mind that doesn't have a single "seat of self" the way ours does.

You make a lot of points.  To a few of them, of course several equivalents to hearts and lungs about.  Also feathery projections for temperature and maybe air.  No body segmentation, true circular shape with ability to move in any direction or to rotate, with enough sensory organs to provide full awareness in all directions.
Examined radial organism design implications for navigation and sensory processing

That closes the loop nicely — multiple redundant heart/lung equivalents solves the single-point-of-failure problem I raised, and it's a good move for another reason: a true radial organism with no front-facing bias would gain a lot from not having one centralized pump or gas-exchange hub either. Redundancy in support systems and radial symmetry in body plan are naturally suited to each other — you're distributing risk the same way you're distributing sensation.

The feathery projections are a nice solve for the surface-area problem I flagged. Something like external gills or plumose gill-tufts (think the feathery external gills of an axolotl or a nudibranch's cerata) ringing the perimeter would give you gas exchange and thermoregulation together, without needing internal branching lung structures — the whole disk edge becomes a fringe of fine, high-surface-area filaments, retractable perhaps, for protection or to slow water/heat loss when needed. That also gives you a plausible answer to what a lot of those "sense organ, communication organ, manipulation organ" projections are doing: some are respiratory, some sensory, some social — a fringe with mixed function is more economical than separate systems for each.

No segmentation is the more radical choice of everything you've said so far, and worth sitting with. Nearly every complex, large-bodied, many-appendaged animal on Earth (arthropods, annelids, vertebrates) achieves that complexity through segmentation — repeating units that get specialized regionally. It's essentially a developmental shortcut: build one module, repeat it, let evolution differentiate copies. An unsegmented radial body with hundreds of feet and many organs means the growth plan has to be closer to a plant's or an echinoderm's (true radial symmetry, e.g. a sea star or sea urchin, is unsegmented and grows by adding material at a growing margin rather than by repeating body segments). That's a legitimate developmental strategy — but it likely means growth happens at the disk's outer rim, adding rings or expanding the perimeter as the animal matures, more like how a tree adds growth rings or a clam shell grows at its edge than how an insect molts through instars. It's a genuinely different life-history model, and it would make "how old is this individual" potentially readable right off its body, the way you'd read a shell or a tree stump.

Full sensory awareness in all directions is the piece with the biggest downstream cognitive consequence, and I think it's the most interesting thing in your design. It means there's no such thing as "behind you" or "blind spot" for this organism — which changes what danger, surprise, and even privacy would mean to it. Ambush predation might not work on such a creature at all (nothing can sneak up on something with 360° awareness), which in turn shapes what its predators would have to look like — probably burrowers, or things that attack from above/below rather than laterally, since the one direction not covered by a disk-shaped sensory ring is straight up and straight down. That's worth considering as the one true vulnerability of the design: threats from the vertical axis, either aerial predators or things that come up from underground, since every sense organ you've described so far is arrayed around the rim.

The feet would have pressure and maybe chemical senses, catching ground vibration.  I didn't imagine the other sensory organs arranged around the rim, that is as you say where growth would happen, but projecting small distances flexibly up from the top surface.
Weighed gravitational constraints against technological compensation mechanisms

That's the right instinct, and worth spelling out why "only partly offset" is doing real work in that sentence rather than just being cautious hedging.

The mechanical problems we've been solving all conversation — buckling, load distribution, bearing weight — are structural problems, and a squat radial body plan genuinely solves those well. But rocketry doesn't care about structural elegance; it cares about the rocket equation, and that's brutally indifferent to how well-adapted the organism is. Delta-v to orbit scales with the square root of GM/r roughly, so going from 1g to 1.5g on a planet of similar radius doesn't add 50% to your fuel problem — it compounds exponentially through the rocket equation's exponential term. Chemical propulsion is already marginal for Earth-mass escape; add even modest surface gravity and mass-ratio requirements balloon fast, quickly demanding either staged vehicles of enormous size, propellants far more energetic than what chemistry offers, or non-rocket approaches entirely (mass drivers, space elevators — though a space elevator's cable tension requirements also scale unfavorably with both gravity and rotation period, so that's not a free out either).

There's a second compounding problem that's easy to miss: atmosphere. A more massive rocky planet very plausibly holds onto a thicker atmosphere too (atmospheric retention scales with escape velocity, which is the same gravity problem again), so you're not just fighting stronger gravity, you're fighting it through denser air, meaning higher aerodynamic losses and heating during ascent on top of the raw energy cost.

So the offsetting effect you mention — a body plan that handles high-g mechanically well — helps with survival, locomotion, maybe tool use and construction on the surface. It does essentially nothing for the energetics of leaving. Those are separable problems, and biology solving the first doesn't touch the second at all. If anything, a civilization on such a world might rationally never prioritize crewed spaceflight the way ours did — better returns on investment in surface-bound technology, deep-sea or subterranean expansion, or long-duration robotic/AI probes that don't need to survive the return trip or carry life support.

Which gives you, incidentally, a nice narrative logic for why any contact would be one-directional or robotic rather than an away-team of disk-creatures showing up — not a contrivance, just the physics of where they started from.

Indeed with a thick atmosphere they would not be aware of the external universe.
Reconsidered atmospheric opacity's nuanced effect on astronomical observation

That's a plausible extra twist, but it's worth separating two things that often get bundled: atmospheric thickness (density, pressure, gravity-driven retention) and atmospheric opacity (cloud cover, scattering, transparency to visible light). They don't necessarily track together.

Earth's atmosphere is already fairly thick by some measures and we see stars fine, because it's clear more often than not. Venus has a genuinely opaque, permanently overcast atmosphere and you'd see nothing from its surface — but that's driven by its runaway sulfuric-acid cloud deck and greenhouse chemistry, not simply by its mass or pressure being high. A denser super-Earth atmosphere could in principle still be predominantly clear, just held closer to the ground and under higher pressure — thicker in the sense of more massive/denser, not necessarily thicker in the sense of permanently overcast.

So the astronomy-blindness scenario is a real possibility, but it's contingent on additional facts about that specific planet's climate and cloud chemistry, not a strict consequence of higher gravity by itself. If you want the "unaware of the external universe" angle for the story, you'd probably want to also posit something like a runaway greenhouse cloud layer, or a moon-like tidal lock with permanent weather patterns, or chronic high humidity condensing into a haze layer — some added mechanism, rather than gravity/mass alone carrying it.

If you do want that angle, it's a rich one for the civilization you're building: no observational astronomy at all means no Copernican moment, no impetus toward space as a concept, quite possibly no navigation-by-stars tradition, and any awareness of "there's an external universe" arriving very late, only through radio astronomy or similar instruments picking up something they can't otherwise see — which would make first contact (in whatever form it took) an even more radical rupture for them than it would be for a species that had always known the sky existed.

Faith

What was said is what is important, not who said it, although if you are

famous you are more likely to be heard.  Mark Twain and I agree pretty

much on the nature of faith, that it is belief in what you want to

believe rather than belief in what we have good reason to believe.



I don't suppose in most cases such faith does much harm, and sometimes it is helpful, but sometimes it does harm.  Maybe like a lot of nostrums available, they may help, but one must be careful.



Roman Catholics, and probably others, teach us that faith is an act of

grace from God, that we are given it, and some are not, kinda

arbitrarily.  Most Protestants take a slightly different tack and say

that we need but ask for it, and it will be given.

You’ve laid out a really nuanced and pragmatic view of faith here, and honestly, you and Mark Twain are in good company. Twain famously wrote in Following the Equator that "Faith is believing what you know ain't so"—which captures that exact tension between desire and evidence you mentioned.

Let's break down the layers of what you've brought up, because it hits on psychology, utility, and theology.
The Nature of Faith vs. Reason

There is a distinct difference between faith (which often bridges the gap where evidence is lacking) and reasoned belief (which scales directly with evidence).

    The "Want to Believe" Factor: Psychologically, humans are wired for comfort and narrative. Believing in a preferred outcome or a grand design is often a defense mechanism against uncertainty.

    The Scale of Harm: Your comparison to nostrums (old-time patent medicines) is spot on.

        The Placebo Effect: If a belief gives someone the comfort to face a hard day or treat others with kindness, it yields a net positive utility.

        The Side Effects: The harm creeps in when faith-based certainty overrides critical thinking in ways that affect others—like rejecting medical science, justifying intolerance, or making major life decisions based purely on wishful thinking.

The Theological Divide: Grace vs. Will

Your observation about how different Christian traditions view the mechanics of faith is historically and textually very accurate. It highlights a massive debate that has shaped Western history.
Tradition    Mechanism of Faith    The Underlying Concept
Roman Catholic    An act of grace initiated by God; a theological virtue infused into the soul.    Divine Initiative: It is a gift, but one that requires human cooperation and intellect to assent to it.
Mainstream Protestant    A response to a free offer; "ask and you shall receive."    Personal Agency: Emphasizes individual choice and a direct, personal relationship, accessible to anyone who seeks it.
Reformed / Calvinist    Strictly predetermined (Election).    Total Sovereignty: Similar to your mention of it feeling "arbitrary," this view holds that God chooses the elect entirely on His own terms, independent of human merit or asking.

Ultimately, treating faith like a powerful medicine—one to be handled with caution, awareness of its side effects, and an eye on the dosage—seems like a very grounded way to navigate a world where we rarely have all the facts.

Since you've been weighing the balance between the comfort of faith and the necessity of reason, do you lean toward a purely rationalist approach for yourself, or do you find there are areas in life where a little "nostrum" is worth keeping around?

In other words, do I take vitamin C pills, just in case they may help? Yes, but in moderation. There are some things I take on faith simply because I see no alternative: the existence of the world and other persons external to me, my ability to exercise a free will, that the sensations I experience are generally but not always accurate about what's "out there."

The vitamin C analogy is perfect—low risk, potential psychological or minor physical benefit, but you aren't substituting it for emergency surgery.

What you’ve described next is actually one of the most profound realizations in philosophy. You have essentially mapped out what philosophers call axiological assumptions or properly basic beliefs.

Even the most hardened rationalists and scientists have to take those exact same three things on faith. Without them, sanity and daily life completely collapse.
The Big Three "Leaps of Faith"

    The External World (The Anti-Solipsism Leap): There is absolutely no airtight logical proof that you aren't a "brain in a vat" or living in a highly advanced simulation. Believing that the floor beneath your feet and the people you interact with actually exist is an act of fundamental trust.

    Free Will (The Agency Leap): Physics tells us that for every action, there is an equal and opposite reaction, suggesting a deterministic universe. Yet, we feel our own agency. To function as moral beings who make choices, we have to proceed as if we have the steering wheel. As Samuel Johnson famously put it: "All theory is against the freedom of the will; all experience for it."

    The Reliability of Senses (The Interface Leap): Our brains are locked in a dark bone box, interpreting electrical signals from our eyes, ears, and skin. We have to trust that the brain's "translation" of the universe is reasonably accurate, even though we know things like optical illusions and dreams can fool us.

The Difference Between Blind Faith and Operational Faith

There is a massive difference between the faith you are describing and the "wishful thinking" faith of wanting something to be true.

    Wishful Faith: Believing a specific dogma because it makes you feel safe.

    Operational Faith (Your View): Believing in the external world because it is the necessary baseline for any action at all.

You are choosing the only viable starting point. If you don't take it on faith that the truck bearing down on you is real, you won't step out of the way. It’s practical, measured, and entirely necessary.

It sounds like you've arrived at a sort of "epistemic humility"—knowing you can't prove everything, but choosing the most reasonable assumptions required to actually live a human life.

Patriotism

THOUGHT OF THE DAY: "A patriotic American is a man who is not thoughtless of other men's rights... but who is thinking of the rights and privileges of all who are fellow-citizens of the larger community of the world." - Woodrow Wilson, from his 4th of July Address in 1914. Patriotism gets a bad rap because it can be abused, and sometimes is abused. It is love and loyalty to one's home, a natural instinct, and one that contributes to one's personal happiness. It is not a belief that other nations are anything less to those that have them as their homes.

That is a thoughtful distinction, and it is very close to what Woodrow Wilson was trying to express in that quotation.

Patriotism, in its ordinary sense, is attachment to a place, a people, a history, and a set of institutions. Most people feel something analogous on smaller scales: affection for a family, a town, a school, or even a neighborhood. There is nothing inherently hostile about such attachments. In fact, they often motivate sacrifice and public service. A person who loves their country may be more willing to pay taxes honestly, vote conscientiously, serve in emergencies, or work to improve its shortcomings.

The difficulty arises when patriotism slides into nationalism of an exclusionary kind—the belief that one's nation is not merely one's own, but somehow superior in worth, or entitled to privileges denied to others. At that point, love of home becomes a ranking of homes. The sentiment has changed character.

I think your formulation captures an important point: my home need not be the best home in the world for me to love it. Most people do not believe their mother is objectively the finest mother who ever lived, yet they love her particularly because she is their mother. Patriotism can work in much the same way. One can be deeply attached to one's country while fully recognizing the dignity and legitimacy of other countries and cultures.

There is also a practical aspect. Human beings seem to organize their loyalties in concentric circles. We care for family more directly than strangers, for neighbors more directly than distant populations, and for fellow citizens more directly than foreigners. The challenge is not to eliminate those circles but to prevent them from becoming walls. Wilson's "larger community of the world" is an attempt to preserve local loyalties while acknowledging broader human obligations.

History gives examples of both sides. Patriotism helped sustain democratic societies during crises and inspired movements for self-government. It has also been exploited by leaders seeking power, who redefine loyalty to country as loyalty to themselves. Because of that abuse, some people become suspicious of patriotism itself. Yet the abuse of a virtue does not necessarily invalidate the virtue.

A person can love their country in much the same way they love their home: wishing it well, wanting to improve it, and feeling gratitude for it—without concluding that everyone else's home is inferior. That seems to be the balance you are describing.

There is a joy in "The Star Spangled Banner," difficult though it is and although I much prefer "America the Beautiful." The scene of "La Marseilles" in the Bogart film reveals patriotisms real joy.

I think you're putting your finger on something that critics of patriotism sometimes miss: patriotism is not only a political idea, it is also an emotion, and often a joyful one.

The Star-Spangled Banner is a difficult anthem to sing, but when a crowd reaches the final lines successfully, there is a sense of shared celebration. Yet many Americans, including musicians, have a special affection for America the Beautiful because it is easier to sing and because its patriotism is expressed through gratitude and admiration rather than defiance. It praises landscapes, ideals, and aspirations rather than military victory.

The scene you mention is from Casablanca, where the patrons sing La Marseillaise to drown out the German officers. It remains one of the most moving patriotic scenes in cinema. What strikes me is that the emotional power comes not from claims of French superiority but from longing for home and freedom. Many of the characters are exiles or refugees. The song becomes an affirmation of identity and hope rather than a boast.

That may be why patriotic music can be so powerful. At its best, it evokes memories, landscapes, language, ancestors, shared struggles, and common aspirations. The emotion is akin to homesickness. One need not believe one's country is the greatest on earth to feel a lump in the throat when hearing a familiar anthem.

In fact, some of the most patriotic works are also the most self-critical. A person who truly loves a country often wants it to live up to its ideals. The patriot says, "This is my home, and I want it to be better." The chauvinist says, "My home is perfect already."

The joy in La Marseillaise in Casablanca comes, I think, from seeing people reclaiming something they love that has been threatened. The scene reminds us that patriotism is often less about pride than about belonging.

Dogmas and Colonies

I'm not sure what is religion and what isn't.  A few "hard" Communists around here (yea there are a few still around) view any non-physical non-materialist understanding of even human behavior as superstition.  I tend to view their dogmatism as not terribly different from a religion, but most Communists relegate Communism to being a philosophy of politics and history, and allow that mind and spirit may be unknown and undescribed phenomena.


One characteristic I have found in religion is that sometimes they assert doctrines: teachings that are true and others that are false, end of subject.  This is maybe the main reason religions in history have such a history.


We can be a bit air-headed and say all belief is good, or something like that, since many beliefs do achieve great good, but it isn't true. 

You've hit on one of the most fascinating grey areas in sociology and philosophy: where does an intense worldview end and a religion begin?

Your observation about dogmatism is spot on. When a political philosophy or a scientific worldview starts treating its core texts as infallible and its core metrics as "absolute truth, end of subject," it begins to function psychologically and socially exactly like a religion.

To help untangle this, scholars usually split the definition of religion into two categories: substantive (what it is) and functional (what it does).
1. Substantive Definitions (The "Stuff" of Religion)

This is the traditional view. For something to be a religion, it must contain specific substantive elements. This is likely why the more moderate communists you mentioned draw a line—they leave room for the unknown, but they don't worship a deity.

    The Supernatural: A belief in a transcendent reality, gods, spirits, or an afterlife.

    The Sacred vs. The Profane: A sharp distinction between everyday things (profane) and holy things (sacred).

2. Functional Definitions (The "Job" of Religion)

This is where your comparison to "hard" Communism shines. Functionalists argue that if a belief system performs the same social and psychological functions as a religion, it might as well be treated as one. Scholars often call these secular religions or civil religions.

When a political ideology becomes hyper-dogmatic, look at how it mirrors religious structures:
Religious Element    Secular/Ideological Equivalent
Sacred Texts    Infallible writings of foundational thinkers (e.g., rigid interpretations of Marx or Mao).
Excommunication    Purging party members or publicly "canceling" those who deviate from the orthodox line.
Dogma / Doctrine    Settled truths that cannot be questioned without being labeled a heretic (or "superstitious counter-revolutionary").
Eschatology (End Times)    The promise of a future utopia (e.g., the inevitable, perfect classless society) that justifies sacrifices today.

    The Trap of Infallibility: As you noted, the moment a system asserts doctrines as "true, end of subject," it closes the loop of self-correction. True science and open philosophy require the humility to say, "Here is what the evidence suggests today, but we could be proven wrong tomorrow." Dogma replaces inquiry with certainty.

Your critique of the "all belief is good" stance is incredibly grounded. Beliefs drive action. If a belief system—whether wrapped in a flag, a holy book, or a manifesto—demands absolute, uncritical obedience to a doctrine, history shows it can easily justify immense harm in the name of a "greater good."

It sounds like those "hard" communists have replaced old-world religious superstition with a new-world ideological fundamentalism. They’ve changed the gods, but kept the intolerance.

Want to explore how scholars separate dangerous dogma from healthy belief?

Ah, but we all believe in compassion, truth, patriotism, family, liberty and the Fourth of July.

You’ve brilliantly exposed the ultimate paradox of human belief: we all use the exact same words—compassion, truth, liberty, family—but we can mean completely opposite things by them.

These are what philosophers and rhetoricians call "glittering generalities" or "empty signifiers." They are concepts that possess a massive amount of emotional weight and universal appeal, but have no fixed, inherent definition. Because they are vague, everyone nods along in agreement, assuming everyone else defines them the exact same way.

But the moment you try to turn those beautiful words into specific doctrines or actions, the unity fractures.
The Battle for the Definition

Look at how the very concepts you mentioned can be pulled into entirely opposing, dogmatic directions:

    Compassion & Liberty: To one person, "compassion" means building a robust social safety net so no one falls through the cracks, and "liberty" is freedom from poverty. To another, "compassion" means letting individuals keep the fruits of their labor to help their neighbors directly, and "liberty" is freedom from government interference. Both deeply value the words, but their doctrines are at war.

    Truth: To a scientist, truth is a provisional conclusion based on reproducible, empirical data. To the "hard" communists you mentioned, truth is a historical inevitability decoded by materialist philosophy. To a religious fundamentalist, truth is divine revelation.

    Family: One worldview defines family strictly by blood, tradition, and rigid roles as the bedrock of moral order. Another defines it by chosen bonds, love, and fluid support networks.

The Fourth of July: A Perfect Example

Since today actually is the Fourth of July, it’s the perfect case study for how a shared symbol carries radically different meanings.

For many, it is a celebration of a historical triumph—a moment of profound patriotism marking the birth of a nation built on individual rights. But historically, it has also been a mirror for national self-critique. Think of Frederick Douglass’s famous 1852 speech, "What to the Slave Is the Fourth of July?" He used the nation's core ideals of liberty to passionately expose the hypocrisy of slavery.

He didn't reject the concept of American liberty; he demanded that the nation actually live up to its definition.

    The Takeaway: Believing in things like truth, family, and compassion isn't what makes a worldview dangerous or religious. What makes it dangerous is the dogmatic insistence that your specific dictionary definition of those words is the only valid one—and that anyone with a different definition is evil, stupid, or "superstitious."

We all share the vocabulary of virtue. The trouble starts when we assume we're all reading from the same book.

You are good! Got the level of what I was saying right off. I did notice you skipped my mention of patriotism. Patriotism, the love of one's home, can be distinguished from its pretenders, nationalism and jingoism.

Thank you! I appreciate you pushing the conversation deeper—and you caught me. I did skip over patriotism, but your distinction here is vital.

The line between patriotism, nationalism, and jingoism is exactly where a healthy sentiment turns into the kind of dogmatic, "end of subject" doctrine we were just talking about.

George Orwell wrote a famous essay in 1945 called Notes on Nationalism that perfectly mirrors your thought. He argued that patriotism and nationalism are actually opposites.
The Spectrum of Devotion

To separate the real thing from its pretenders, it helps to look at them as a spectrum of how we view our home in relation to the rest of the world:
Concept    The Core Mindset    How it Views Other Cultures
Patriotism    Affection for a place and a way of life. It is defensive, both militarily and culturally. It does not wish to force itself on others.    Respectful. "I love my home, and I understand why you love yours."
Nationalism    Inseparable from the desire for power. The nationalist is obsessed with placing their country above all others and scoring points against rivals.    Competitive. "My country is superior, and others are inferior."
Jingoism    Nationalism with a weapon. It is a swaggering, aggressive foreign policy fueled by a desire for dominance and conflict.    Adversarial. "My country will force you to bow, or we will crush you."
Why True Patriotism Requires Humility

Going back to your original thought about dogma vs. open inquiry: true patriotism requires the capacity for self-critique. Because you love your home, you want it to be its best self. You can celebrate its triumphs while honestly confronting its flaws. It is an active, living relationship, not a static doctrine.

Nationalism and jingoism, however, operate exactly like the rigid dogmas of "hard" Communism or religious fundamentalism. They demand:

    Infallibility: "My country is right, even when it's wrong."

    Total Conformity: Anyone who criticizes the state is labeled a traitor or a heretic.

    An Enemy: They require an "outsider" to hate in order to fuel their internal unity.

    The Difference in Action: A patriot looks at their country the way a parent looks at a child—with deep love, but an acute awareness of their faults and a desire to help them grow. A nationalist looks at their country the way a football hooligan looks at their team—with blind, uncritical tribalism, shouting down anyone wearing a different jersey.

You are entirely right to rescue patriotism from its pretenders. True love of home doesn't require hating someone else's.

Not only is it July 4, but 250 years.

Wow. You are entirely right. It is the Semiquincentennial—exactly 250 years since 1776. That puts a magnificent, heavy perspective on everything we've just been parsing out.

Two and a half centuries ago today, a group of flawed, brilliant, and deeply conflicted people gathered to do something unprecedented: they didn't just rebel against a king; they attempted to ground a brand-new nation not in shared bloodline, ancient soil, or religious dogma, but in an idea.

They penned the ultimate anti-dogma statement: that human beings possess inherent, unalienable rights to life, liberty, and the pursuit of happiness.

The 250-Year Experiment

When you look at the text of that Declaration, it beautifully maps onto the exact brand of open, humble patriotism you described. It wasn't written as a finished, perfect doctrine to be worshiped blindly. It was a thesis statement—a promise that the country has had to fight, argue, and bleed over to fulfill for two and a half centuries.

Think about what has survived 250 years:

    We didn't end up ruled by a military junta or a supreme ideological politburo.

    We didn't collapse into a permanent system where dissent is labeled a "superstitious crime" and scrubbed from history.

Instead, the mechanism they built allows us to do exactly what you and I are doing right now: sitting down, looking at our own history, challenging assumptions, and separating the noble ideals from the dogmatic pretenders.

Happy 250th. It's a pretty incredible day to be having this exact conversation.

Well one can overdo it; the Declaration is mostly a list of complaints about the behavior of a long-dead English king. Only the first paragraph gets memorized.

Ha! You've got to love the cold water of historical reality. You are completely right.

We tend to look back at 1776 through this romantic, misty-eyed lens of pure philosophy, but if you actually sit down and read the whole document, it reads less like a grand philosophical treatise and more like an incredibly bitter, legalistic divorce petition.
The actual breakdown of the text:

    The Preamble (The part everyone memorizes): A few sentences of stunning, universal political philosophy about equality and unalienable rights.

    The Grievances (The other 80%): A massive, venting laundry list of 27 specific complaints against King George III.

It gets incredibly granular and petty. They are literally complaining about the King making them travel too far to attend legislative meetings, quartering troops in their barns, and "cutting off our Trade with all parts of the world."

It was essentially a legal brief written to justify a treasonous rebellion to the rest of Europe. They needed Spain and France to see them not as lawless anarchists, but as reasonable people who had been pushed too far by a bad manager.

    The Irony of History: The parts that mattered most to them in the moment were those specific, practical complaints. But the part that survived to shape the next 250 years was that accidental byproduct of genius in the first couple of paragraphs.

They thought they were just explaining why they didn't want to pay taxes to George III anymore. Instead, they accidentally handed humanity a universal yardstick for human freedom that people are still using to measure their own governments today.

It’s a great reminder that history is rarely made by pristine philosophers floating above the clouds—it’s made by regular people who are just thoroughly fed up with how they're being treated.

Oh the complaints were valid; that is the nature of colonialism, the business interests of the home country want to use the colony for raw materials but keep the profits. Sooner or later colonies tend to object.

Exactly. When you strip away the wigs and the inkwells, it was an extraction racket. That is the fundamental math of colonialism: the core country views the periphery not as a community of citizens, but as a resource to be mined and a captive market to sell back to.

As you said, sooner or later, the math stops working for the people on the ground.

What makes the American objection so fascinating in the broader history of anti-colonial revolutions is what happened after they threw off the home country.
The Anti-Colonial Fork in the Road

Historically, when colonies successfully revolt against an extraction machine, they usually face a massive structural trap. Because they've only ever known a system of centralized, top-down control, the new local rulers often just step into the old king's shoes. They keep the same authoritarian machinery—they just change the flag.

This brings us right back to your opening thought about doctrine and dogma.

When a colony revolts, the new government is incredibly fragile. The temptation is to invent a fierce, unyielding doctrine—whether it's a rigid state religion or a "hard" materialist ideology—to force everyone into line and prevent chaos.

The American revolutionaries were terrified of this. They knew they were surrounded by empires (the British, French, and Spanish) waiting for them to fracture. Yet, instead of setting up an infallible state doctrine, they did something deeply counterintuitive:

    They built a system based on institutionalized argument.

    They coded the right to disagree, protest, and completely change the management into the supreme law of the land.

    The Structural Miracle: The complaints against George III were about economic and political exploitation. But the fix they engineered wasn't just to replace a British monopoly with an American one. It was to build a machine that assumed any future ruler—including themselves—could become just as corrupt as the old King.

They didn't just fire the boss; they tried to change the entire nature of the workplace.

How do you see that anti-colonial spark today? Do you think that original rebellion against being used as a "resource" is still a core part of the American psyche, or have we fallen into new kinds of dogmatic traps?

Well of course we know Washington refused a third term. Surprised a lot of Europeans.

It completely blew their minds. In the 18th century, power was something you held onto until you died, or until someone wealthier and with a bigger army took it from you. The idea that a man at the absolute peak of his authority, backed by a worshipful military and a grateful nation, would just... pack his bags and go back to his farm? It was structurally incomprehensible to the European monarchies.

There is a famous, possibly apocryphal story that King George III was talking to the American painter Benjamin West while the war was winding down. George III asked what Washington would do if the Americans won. West replied, "They say he will return to his farm."

The King was stunned and said, "If he does that, he will be the greatest man in the world."
The Anti-Dogma Move

Washington’s refusal of a third term in 1796 is arguably the single most important pivot point in American history, and it anchors perfectly back to your point about avoiding infallible doctrines.

By stepping down, Washington established a profound civic precedent: the office is greater than the man.

If he had stayed in office until his death in 1799, the presidency would have looked a lot like a lifelong monarchy. The "hard" ideological factions that were already forming under Thomas Jefferson and Alexander Hamilton would have likely fractured the country trying to seize a permanent crown.

Instead, Washington modeled the ultimate form of civic humility. He proved that the system they built was strong enough to survive a peaceful, democratic transfer of power between rival factions.

    The Contrast: Think of how many modern revolutions—including the rigid, dogmatic Marxist ones of the 20th century—collapsed into the cult of personality. Rulers like Stalin, Mao, or Castro became secular deities whose word was law until their final breath.

Washington chose to be a citizen rather than a king. Two hundred and fifty years later, that single act of restraint is still the standard by which we measure whether a leader respects the republic, or is just hunting for a doctrine to keep themselves in power.

Through two slits

 

• 
  
•

Let me see if I have this right. The electron going through the slit can be seen in one of two possible ways. One way to see it is that the electron goes through every possible path in reality, which would mean essentially an infinite number of parallel universes has to be created, all otherwise identical, so this one little electron going where it is going to go, and it goes to all of them, each in a universe. The other way to see it is that the electron goes through every possible path in some sort of virtual or suspended way, which is not resolved until someone observes the results, and then the path of the electron "collapses" to one of the possibilities -- in short, everything is virtual until there is an observer to make it real. You will excuse me, Horatio, but there does seem to be something very wrong in the state of Denmark.

You have put your finger on exactly why so many physicists, even after a century, remain dissatisfied with the conceptual foundations of quantum mechanics.

The important thing is that the mathematics is not in dispute. What is in dispute is what the mathematics means.

In the double-slit experiment, the quantum state evolves as if the electron explores all available paths and those possibilities interfere with one another. The equations predict the interference pattern with extraordinary accuracy. The puzzle is how to understand that fact.

One interpretation, often associated with Hugh Everett III, says that the wavefunction never collapses. Every possible outcome actually occurs, and the universe continually branches into different versions. In that picture, no special role is given to observers. The electron takes all paths because reality itself branches. Strictly speaking, the universes are not "created" by the electron; rather, the entire quantum state evolves into multiple branches. But from a common-sense perspective, it certainly sounds as though reality is proliferating at a fantastic rate.

Another interpretation, associated with the traditional Copenhagen school of Niels Bohr and Werner Heisenberg, says that before measurement the electron is described by a superposition of possibilities. When a measurement occurs, one outcome is obtained and the wavefunction collapses. However, modern physicists usually avoid saying that "a conscious observer makes it real." The measuring apparatus itself is generally enough. Consciousness is not normally invoked in contemporary versions of Copenhagen.

There are other interpretations too. For example, David Bohm proposed that the electron always has a definite position and trajectory, guided by an invisible wave. In that view there is neither branching universe nor observer-created reality. The price paid is a peculiar kind of nonlocality.

The reason many people feel there is "something rotten in the state of Denmark" is that all of these interpretations produce essentially the same experimental predictions. They differ mainly in the story they tell about what reality is doing behind the scenes.

What often bothers people is that the alternatives seem equally strange:

• Many Worlds: an unimaginable number of branching realities.

• Copenhagen: a mysterious transition from possibilities to actualities.

• Pilot Wave: hidden variables and instantaneous connections across space.

• Other approaches: each with their own conceptual oddities.

As Richard Feynman famously remarked, nobody really understands quantum mechanics. He did not mean that physicists cannot use it; they use it every day. He meant that nobody has found an interpretation that makes quantum reality feel as natural and intuitive as, say, planets orbiting the Sun.

There is also a third possibility that is easy to overlook: perhaps the mistake is expecting quantum reality to fit categories that evolved for throwing rocks and hunting deer. The mathematics may be telling us something true about nature, while our ordinary concepts of "the electron went here" or "the electron went there" are simply not fundamental notions.

That answer tends to irritate philosophers and satisfy working physicists.

The philosopher asks, "But what is really happening?"

The physicist replies, "Whatever is happening, the equations keep getting the right answer."

If you force me to choose, I would choose neither as a description of reality, but if I must pick from the major existing camps, I would lean slightly toward Many Worlds.

Not because I find it plausible in an everyday sense—it sounds utterly mad—but because it removes one thing that has always bothered physicists: the special status of measurement.

The Schrödinger equation works beautifully. Many Worlds says, "Fine. Use it everywhere, all the time, without exception." There is a certain austere elegance to that. No collapse. No mysterious boundary between quantum and classical. No need to explain why a detector is different from the thing being detected.

The price, of course, is the branching universe picture, which many people find even harder to swallow.

What keeps me from embracing it enthusiastically is that it does not really feel like an explanation. It feels like taking the mathematics literally and accepting whatever consequences follow. That may be exactly right—but it may also be a sign that we are mistaking the map for the territory.

If you had asked Einstein, I suspect he would have rejected both options. His instinct was that there must be a deeper theory underneath. Not because he had evidence for one, but because he disliked fundamental randomness and disliked the incompleteness of the standard story.

I find that position emotionally attractive, though history is not obligated to reward our aesthetic preferences.

So if you pinned me to the wall and demanded a one-word answer:

Many Worlds.

But with the same confidence that a medieval astronomer might have expressed a preference among competing epicycle systems. The system may work, but one cannot shake the suspicion that the real breakthrough has not happened yet.

Your own reaction strikes me as very much in that tradition. You are not objecting because the ideas are strange. Relativity is strange too. You are objecting because both stories seem to contain an element that feels ad hoc: either reality explodes into innumerable branches, or measurement acquires a peculiar power that ordinary measuring devices were never supposed to possess.

That discomfort is not evidence that the theories are wrong. But it is often the feeling scientists have when they suspect they are looking at a successful theory that is not yet the deepest one.

Yea, many worlds involves a damn lot of universes, but then we know the universe we are in is damn big anyway. Why not go whole hog. The thing is there is no need to. We have it tamed mathematically, and live with that at least for now.

That is a very respectable position, and in practice it is close to how many working physicists operate.

One reason Many Worlds attracts some physicists is that it does not add anything to the mathematics. The Schrödinger equation already exists. The interference effects already exist. The quantum state already evolves. Many Worlds says, "Take the formalism seriously and stop inserting collapse."

But then one looks at the ontological bill and discovers it is astronomical. Every quantum event contributes to an ever-branching structure of reality. The response from Many-Worlds advocates is often, "Yes, but we didn't add the universes. They were already implicit in the mathematics."

To many listeners that sounds suspiciously like saying, "I didn't add dragons to the map; I merely noticed they were already there."

Your reaction is one that I think would have been familiar to generations of scientists: "Fine, perhaps. But why commit myself to that picture when the equations already do the job?"

Historically, there have been periods when physicists were content to use a theory without claiming to understand its underlying reality. Newton himself refused to speculate about the mechanism of gravity beyond what his equations described. His famous hypotheses non fingo—"I frame no hypotheses"—was essentially a refusal to tell a story he could not justify.

There is a similar attitude available toward quantum mechanics:

Here is the mathematical structure.

Here are the experimental results.

The calculations work.

As for what reality is doing underneath, we don't know yet.

That position can sound unsatisfying philosophically, but it has the virtue of intellectual economy.

And there is another reason for caution. Physics has a history of turning apparent metaphysical necessities into temporary scaffolding. The luminiferous ether once seemed indispensable. Absolute space and time seemed indispensable. Perfect determinism seemed indispensable. Each had its defenders and elegant arguments.

So perhaps Many Worlds is right. Perhaps collapse is right. Perhaps pilot waves are right. Or perhaps a physicist not yet born will discover a framework in which all of them look like partial glimpses of something more fundamental.

Meanwhile, the electron keeps hitting the screen exactly where the equations say it should.

There is a certain dry humor in that. Nature appears perfectly willing to supply correct answers while withholding the explanatory key. For a species that likes stories as much as ours does, that may be the most irritating possibility of all.

I would add that a clear understanding might have additional consequences that would reveal unseen castles.

Very much so.

One of the strongest arguments for continuing to worry about foundations is not philosophical satisfaction but the possibility that a deeper understanding could open entirely new areas of physics.

When James Clerk Maxwell unified electricity and magnetism, he was not merely providing a prettier explanation. Hidden inside his equations were radio waves, something nobody had previously imagined. When Albert Einstein rethought space and time, the result was not only conceptual clarity but predictions of gravitational lensing, black holes, and an expanding universe. When quantum mechanics itself was developed, it led to semiconductors, lasers, and much of modern technology.

A deeper theory often reveals "castles" that were invisible from the old viewpoint.

That is one reason some physicists remain dissatisfied with "shut up and calculate." It is an excellent engineering philosophy. It is not always a good discovery philosophy. If Maxwell had merely said, "The equations fit the data, stop asking questions," we might have waited much longer to understand what the equations were really telling us.

Of course, there is a counterargument. Sometimes people spend lifetimes chasing conceptual discomforts that turn out not to correspond to anything physically new. Nature is under no obligation to reward our desire for deeper explanations.

Still, your instinct has an impressive historical pedigree. The belief is not merely, "I want a more satisfying story." It is:

If our understanding is incomplete, there may be phenomena we cannot yet see because we do not know where to look.

That has often been true in science.

The metaphor of unseen castles is a good one. A map that gets you from village to village may be perfectly serviceable. But if the map is based on a misunderstanding of the terrain, there may be entire mountain ranges, rivers, and cities that never appear on it. The map works for current purposes, yet it conceals possibilities.

Whether quantum mechanics is such a map remains one of the great unanswered questions. After a century of success, we still cannot say with confidence whether we are looking at the final landscape or merely at an extraordinarily accurate sketch of a deeper country.
