What is a beautiful concept or idea that continues to blow your mind?

For me it is Cellular Automata, and more precisely the Game of Life.

Imagine a giant Excel spreadsheet where the cells are randomly chosen to be either “alive” or “dead”. Each cell then follows a handful of simple rules.

For example, if a cell is “alive” but has less than 2 “alive” neighbors it “dies” by under-population. If the cell is “alive” and has more than three “alive” neighbors it “dies” from over-population, etc.

Then you sit back and just watch things play out. It turns out that these basic rules at the individual level lead to incredibly complex behaviors at the community level when you zoom out.

It kinda, sorta, maybe resembles… life.

There is colonization, reproduction, evolution, and sometimes even space flight!

I was kinda oblivious to the world of FOSS until simultaneously switching to Lemmy and also resuscitating an old computer by installing Linux. It took a long time for me to wrap my head around the fact that people are just cranking out parts of OS’s, or pw managers, or file zip utilities for shits and giggles in their free time, and not even charging for it. A game or two as a passion project I could understand, but who sits down after work and plods through a zip utility?

After years and years of “if the service is free, you’re the product” it really takes some time to rewire my brain. It’s almost enough to make me wish I went into software instead of mechanical, so I could pitch in on something.

Symbiosis in nature….it always brings up feelings of awe and wonder for me. Especially in forests. The “wood-wide web” or “mycorrhizal network” being my latest obsession . The fact that the fungi joins the trees together through the roots to allow for exchange of nutrients, water, and chemical signals between plants. And then there’s the forest canopy, and the role it plays in keeping the forest healthy.

Trees are awesome.

Black holes and the uncertainty of what lies behind the event horizon. The possibility that inside a black hole, a whole new universe could exist without us ever knowing. When tripping through life taught me one thing, it is that many things can be seen as part of a huge fractal, and that view fits right into the interpretation that black holes are nothing else than universes in universes. After all, our big bang might just be another ordinary black hole, reaching critical mass.

Of course I can not prove it, but I love thinking about it.

Anyone able to ELI5 why wormholes and dimensional pockets are prevailing theories on black holes?

Like, I’ve got a lot of sci-fi under my belt and I need to figure out the sci part of it.

Hazzia,

I can’t remember if it was a youtube video or a paper or an article or what, but I saw something explaining that, based on one interpretation of Einsteins equations, past the point of singularity, space and time invert. This would mean that the longer the black hole exists around in “our” universe (in absolute terms), the larger it becomes on the inside, and the larger it gets on the outside, the longer the inside universe would persist. I feel like you would have liked it, if only I could remember what it was. :(

The thing I saw postulated both that the universe would reuse the matter the black hole absorbed, and that there would be infinite branching universes since each would develop their own black holes, but then you have an issue with regards to running out of matter at some point. Though I guess that could be solved if you assume every black hole must converge at the end of their containing universe’s lifespan, and all matter would be reused in whatever blackhole absorbs the blackhole containing that parent universe? Oh hey, we’re back to fractals again!

Personally I’m a fan of the idea of black holes as topological stars that fall in line with string theory, but there have been so many hypothetical frameworks coming out in recent years that are just fascinating to think about.

I think the only reason those specifically are most well known, is because they capture popular imagination.

Basically, because it’s impossible to see inside black holes to know what’s going on, there’s very few ways to validate ideas. Therefore, outside of a select number of external observational techniques (like radio signals and gravitational waves) to place some limitations, ideas about what happens beyons the event horizon are in the realm of pure math, which people don’t care about unless it either A. Verifiable, or B. Just sounds really cool.

Black Hole hypotheses therefore tend to go one of a few ways:

Scenario 1

Scientist A: Hey if you use this math, black holes can do this thing

Scientist B: That requires this other thing which isn’t true, to be true, and/or breaks this fundamental law

Scientist A: This hypothesis is my precious brain baby and if you talk shit about it I will shatter your knees

Scenario 2

Scientist A: Hey if you use this math, black holes can do this thing

Scientist B: That requires an assumption we can’t, or have yet to, verify is true (almost always somehow related to string theory)

Scientist A: This hypothesis is my precious brain baby and if you talk shit about it I will shatter your knees

Scenario 3:

Scientist A: Hey if you use this math, black holes can do this thing

Scientist B: Okay the math checks out as one of X number of possibilities with that same math, but there’s know way to tell which, if any of these would be true (equations with multiple valid solutions, almost always related to spacetime topology)

Scientist A: Heehee numbers do funni

ETA: The specific subcategories of hypotheses you mentioned also have an inherent advantage of not having to deal with singularities. Why that’s good: Einstein’s theories say infinite density impossible. With singularity, can’t connect quantum theory to relativity theory. No quantum gravity make math bb’s big sad. Solution? Instead of squoosh matter really tiny, just send it somewhere else! They aren’t the only frameworks that avoid singularities, but definitely the coolest sounding and least complicated

Thank you! I love this breakdown. I had a suspicion it was like this all along but lack the astrophysics background.

Not sure why astrophysicists are so quick to pull a Tonya Harding, though.

Hazzia,

They hate to admit it, and it’s definitely less in-your-face most of the time because of the expected formality of the scientific community, but physicists, and specifically those trying to make advancements like we see around black holes, are SUPER arrogant. For the first 2 scenarios listed, they usually only make a formal paper out of the discovery to later defend the drawback as something they can “work around”. Either by “oh we’ll definitely eventually figure out how to emperically verify this haha. Look how well it works, you’d be crazy not to believe in this”, or the more extreme “This obviously constitutes a whole rewrite of our understanding of physics because my solution is so elegant except for the parts where it literally doesn’t work”

That last one is less prone to arrogance because topology is working with an insane amount of unverifiable possibilities already, so they don’t really tend to get too attached to any given solution.

On the subject of Conway’s Game of Life, one of the YouTube videos that I always have to go back to now and then is a narrated video of the game being built from the ground up in APL. It’s so wild to see the guy start with a simple expression and the algorithm taking shape as he adds to it step by step. By the end it looks like some magical incantation lol

Conway’s Game Of Life blew my mind when I first saw it live. The fact that it is Turing Complete is crazy too.

DRUMS_,

Alan Watts contextualizes our daily lives as the outer, “fine spray” at the edge of the big bang --still exploding. Planets “people-ing” and your daily schedule, relationships, accuisition of goods, etc. is just the complex late stage of the big bang explosion. The explosion is chaos but as time goes by order slips in and creates “complexity”. This is all still an explosion.

claycle,
@claycle@lemmy.world avatar

I am focusing on the “blow my mind” part, rather than the “beautiful” part of your question, but I am certain many philosophically-minded people would consider the following “beautiful”.

Peter Singer’s argument in “Famine, Affluence, and Morality (1972)” that you and most everyone you know are probably immoral or evil and you don’t even realize it. It really affected my ideas of how to strive to live.

Here is a good video explaining the idea in detail, worth 30m of your time.

Peter Singer - ordinary people are evil

hairyfeet,

The presenter focuses on argument 1 because he says the other points are “obviously correct” and therefore moral. Imo that’s flawed.

  1. Hunger disease etc are part of a natural cycle which controls population and ecosystem balance.
  2. Luxuries are of no significance is not obviously true. Our economic system means that purchasing items of “no moral significance” feeds into a system which supports livelihoods and, in a functional government, provides welfare and health care to populations.
  3. There are multiple areas where money could be focused instead of Oxfam etc which could be seen as moral- R&D, luxuries as per 3

(It might just be that I don’t like philosophy)

AgentOrangesicle,
@AgentOrangesicle@lemmy.world avatar

I’m also no philosopher, but I’ve a penchant for ethics.

I feel like the message is diluted a bit given how much he talks about charity in our capitalist society. The question is larger, and it takes some effort to step back and view a collectivist society as it could be.

absGeekNZ,
@absGeekNZ@lemmy.nz avatar

Focusing on your points:

  1. Controlling population - this is flawed completely, the lowest birth rates in the world are in the most affluent countries. In a lot of places it is below the replacement level of 2.1 births/woman. I think it is fine to accept the premise that hunger, disease etc are very bad things.
  2. This is think is much more open to attack than point 2. Luxuries are of no moral significance, in my opinion is a flawed premise because it is both a “Straw Man” and a “Rhetorical Definition”.
  • It is a Straw Man argument because: it is weakening any counter point by hand waving away any possible refutation by using “Luxuries” in a pejorative way (in my opinion).
  • It is a Rhetorical Definition because it is using Luxuries in an emotionally charged way (again in my opinion); it is equating that you as a person, indulging in “Luxuries” are taking a moral stand. Luxuries are not required for life and thus are immoral, when those same resources could be used to save others lives.
  • My refutation: Happy people are generally more productive, having access to some luxuries increases happiness, therefore having access to luxuries increases productivity.
  • This leads to: a more productive society generates more tax revenue that can be used to help others. Thus paying your fair share of tax is a moral good.
  • Counterpoints: Some people will become hedonistic and focus too much on luxuries. Some people will hoard wealth and forgo their moral obligation to pay their fair share of tax.
  • Supporting case: We could look for a real word example…ignoring the situation that lead to it, lets examine the productivity of North vs South Korea, the amount that each country gives to international aid etc…SK gives approx $37USD/citizen, I could not find any data on how much NK gives, we can probably assume it is very low.
  1. What you say here is basically a “rising tide lifts all boats” argument. This is a very valid argument, again using the North/South Korea example, SK has invested heavily in R&D and as an indirect consequence, their ability to help has vastly outstripped that of the North.
  • There is another point here, it seems to me that Singer is providing a “False Dilemma”; essentially saying that there are only two choices here, we either help or don’t help. One choice is good the other evil.
  • I posit that there is a middle ground, we can strive for the ability to enjoy some luxuries without devolving into hedonism, whilst still helping those in need.

In conclusion. You were correct to take issue with the presenter blindly accepting premises 2, 3 & 4. The way you tried to refute point 2 however was not great. Especially since point 2 is the only premise that we can say “is self evident”.

My points are more temporally distant then those of Singer, he is stating that helping now is better than building the ability to help much much more in the future.

raresbears,

I didn’t actually watch the video, but I have read the original essay and I thought I’d offer a few thoughts (and criticisms) of it.

An interesting consequence of his strict utilitarianism is that it follows from it that it’s actually immoral to do anything to help issues close to home in pretty much any way if you live in the West, and maybe even in other countries as well, regardless of whether that may be by donating, volunteering, or anything else of the sort.

if it is in our power to prevent something bad from happening, without thereby sacrificing anything of comparable moral importance, we ought, morally, to do it.

Because of wealth disparities between countries, your money will almost always go further somewhere else. If you live in the West, this difference can be extreme, and as a result any money sent there will be able to accomplish far more than it will for people in your own area. Since your donation to help out nearby is a donation not being made elsewhere where it can do more good, it is then to be considered immoral. A similar logic can be applied to volunteering. If when you’re volunteering you are not working to make money which you could donate to much poorer countries, it’s immoral, because your personal work to do good will never be able to equal what your money could do. In fact, your life should essentially be, to the greatest extent that doesn’t reduce the amount you can make by the harm it does to you, you constantly working. He even admits as much:

Given the present conditions in many parts of the world, however, it does follow from my argument that we ought, morally, to be working full time to relieve great suffering of the sort that occurs as a result of famine or other disasters.

He even goes as far as to say the following:

we ought to give until we reach the level of marginal utility —that is, the level at which, by giving more, I would cause as much suffering to myself or my dependents as I would relieve by my gift. This would mean, of course, that one would reduce oneself to very near the material circumstances of a Bengali refugee.

If this is the case, it has important implications for political action in its many manifestations as well. Should I be campaigning for the government to adopt policies which reduce suffering as much as possible? If implemented their effect could be massively beneficial, but I don’t think this works with the arguments he makes. My individual contribution to a political movement will never be the difference between its success and its failure, so it would seem the moral decision is for me to remain effectively apolitical.

This however strikes me as being in contradiction with this later statements:

I agree, too, that giving privately is not enough, and that we ought to be campaigning actively for entirely new standards for both public and private contributions to famine relief.

I would sympathize with someone who thought that campaigning was more important than giving oneself

Ultimately, I am led to the conclusion that following his arguments, the only moral thing to do is in fact to relentlessly pursue financial gain, as donating the money one earns is far and away the most effective use of one’s time and effort to do moral good. The engineer who could have worked for Lockheed Martin designing weapons for the US military is in fact more moral than the one who turns down the job for one that pays substantially less, since it is practically certain that whoever would take the job otherwise would not donate as generously as they do. Applied to capitalists (the class of people, not the supporters of capitalism), it seems that since giving money is the moral thing to do, and giving more money does more good, making more money is the moral thing to do, as it increases one’s capacity to do good. This seems to be borne out by his statements concerning foreign aid, which indicate that it’s not just about giving what you can in the present moment, but also considering how your actions impact your future ability to continue to do so:

Yet looking at the matter purely from the point of view of overseas aid, there must be a limit to the extent to which we should deliberately slow down our economy; for it might be the case that if we gave away, say, 40 percent of our Gross National Product, we would slow down the economy so much that in absolute terms we would be giving less than if we gave 25 percent of the much larger GNP that we would have if we limited our contribution to this smaller percentage.

I find that this ends up being quite problematic, because the ability to grow one’s own wealth is functionally unlimited. It might seem that that’s not a problem if you’re giving away all your wealth, but for it to grow so you can give more, that can’t be the case, because you need to be reinvesting it. As a result you end up with this contradiction, where your are morally obligated to increase your wealth so you can do more good, but at the same time this obligation prevents you from actually putting that wealth into doing good. You could say that the not doing good with the money means that it’s no longer moral so you have to give at some point, but the problem with that is that it’s impossible to define that point. It still remains that at any given point in time the moral thing to do is to reinvest it so that if you give it next time, more will be given. Ironically, this endless pursuit of ever greater wealth is the very same thing that creates so much suffering in the world, even if its justification is usually different, so this argumentation seems to just end up reinforcing the same ills that it hopes to address.

I do like his conclusion though, directed towards other philosophers, reminiscent of a Marx quote that I’ve always been quite fond of: “The philosophers have only interpreted the world, in various ways; the point is to change it.”

TitanLaGrange,

Does Singer explore how the limits of one’s knowledge about the impacts of their actions might play into the decisions?

Like, I could send $5 to some overseas charity, but I don’t have a good way to know how that money is being used. Conversely, I could use it locally myself to reduce suffering in a way I can verify.

It seems to me that morally I should prioritize actions I know will reduce suffering over actions that may reduce suffering but that I cannot verify. Verification is important because immoral actors exist, so I can’t just assume that moral actions that I delegate to other actors will be carried out. Since it’s easier to have good knowledge about local actions (in particular those I execute personally), this would tend to favor local actions.

raresbears,

Does Singer explore how the limits of one’s knowledge about the impacts of their actions might play into the decisions?

Only very briefly, and not in a way that I think really addresses your specific example:

Admittedly, it is possible that we are in a better position to judge what needs to be done to help a person near to us than one far away, and perhaps also to provide the assistance we judge to be necessary. If this were the case, it would be a reason for helping those near to us first. This may once have been a justification for being more concerned with the poor in one’s town than with famine victims in India. Unfortunately for those who like to keep their moral responsibilities limited, instant communication and swift transportation have changed the situation. From the moral point of view, the development of the world into a “global village” has made an important, though still unrecognized, difference to our moral situation. Expert observers and supervisors, sent out by famine relief organizations or permanently stationed in famine-prone areas, can direct our aid to a refugee in Bengal almost as effectively as we could get it to someone in our own block. There would seem, therefore, to be no possible justification for discriminating on geographical grounds.

simon574,

I’ve watched like 10 minutes and I hate it. Peter Singer is a very controversial figure as it is, on top of that the guy in the video comes off as super condescending to me and I can’t stand watching him for longer. Me personally, I don’t think it’s “immoral” to not give money to charity. And terms like immoral or evil are usually defined by the society you live in and not some random philosopher. And I bet there are good reasons his radical ideas in “Famine, Affluence, and Morality” did not get embedded in our society yet.

PowerCrazy,

I’d say that charity as it exists in a capitalist society is in itself evil, and contributing to it is no better then buying indulgences.

HenriVolney,

Charity is a way to confirm and reinforce the capitalistic oppresion of the poor by the rich. That’s why it is widely promoted by churches whose interest has always been aligned with that of the wealthy and powerful. It’s a magct trick that makes rich people look generous to the public while giving them an occasion to pretend that they are good people in a taught world

claycle,
@claycle@lemmy.world avatar

I do not take issue with anything you said (your opinion is as valid as mine) - up until your last sentence, which piqued my interest.

You seem to be implying that Mr Singer’s “radical ideas” are weak, invalid, or beneath consideration because our society hasn’t embedded them yet. I would like to respond that I think the value of a radical idea cannot, and probably should not, be measured by how well society accepts it. For example, there are a some pretty famous, radical ideas from this rabbi a couple thousand years ago that have totally failed to be embedded in our society, yet his radical ideas arguably still have significant merit. I am thinking specifically of the radical idea of kindness and peace expressed in “turning the other cheek”, an idea we, as a society, have for all intents and purposes rejected.

Otherwise, I would also like to remind you that the OP just asked for ideas that blew our minds. Mr Singer’s idea, when I heard it for the first time, blew mine and I thought it fit the brief.

prole,

That’s an incredibly pessimistic way to view the world… I think it’s more accurate to say that people have the capacity for both good and evil. I’m not sure that you can say that “most everyone you know” are immoral or evil. That’s quite the claim.

Though we would also have to explore what “immoral,” and “evil” actually mean. Am I immoral for purchasing and using a cell phone made with materials that were obtained through means that destroy lives and damage ecosystems?

The modern world is far too complex and interconnected for people to avoid doing things that could be considered immoral or unethical.

HenriVolney,

I guess we can agree on the assumption that everybody is fundamentally egoistic and focused on their personal needs, which is necessary for the survival of the species. The fact that many many people chose to take care of total strangers every day shoes there’s more to us than basic needs satisfaction. We need each other and we need to feel appreciated, which makes us gentle, generous, and caring. “Evil” is a scarecrow for children, “immoral” a tool invented by the bourgeoisie to oppress those that scare them

claycle, (edited )
@claycle@lemmy.world avatar

That’s quite the claim.

Yes, it is, and as explained in the video the original author (and also the person explaining it) admit it is quite a claim, then proceed to demonstrate the veracity of the claim. I suggest you grab a cup of jo, settle in, and watch it. It addresses the points you bring up directly.

[EDIT: Re: Quite a Claim: Yes, and thus fitting the OP’s “mind-blowing” criteria for the thread :-)]

The very short answer to “are you immoral for purchasing a cell phone” is “probably yes”.

The proposition is not an easy one (it accepts it is extreme), but it is hard to deny when you march down the logic.

prole,

Right. And it necessarily follows from that that all humans are therefore immoral. And if that’s the case, there is no longer any utility to the term “immoral.” It becomes a pointless exercise.

claycle,
@claycle@lemmy.world avatar

You’ve committed reductio ad absurdum.

Yes, most people are probably acting immorally and they are not even aware of it.

That doesn’t mean it is a pointless exercise to identify the immoral behavior and strive to reduce or eliminate it, even if it is impossible to completely do so.

prole,

Not most people. Literally every person. Or maybe you could give me an example of a person that wouldn’t be considered immoral by your metric?

claycle,
@claycle@lemmy.world avatar

You are (deliberately?) skipping over the part of awareness.

Take for example a person who is aware that they cannot act morally when making seemingly normal, banal decisions. For example, they may be aware that when they choose to buy a shiny new cell phone when they have an older-but-still-perfectly-working model, they very likely doing something immoral. Because they are aware of the moral implications of their choice, they can choose hold-off buying a new phone for as long as possible (a morally-positive choice) and perhaps - going a step further - even using that money they would have spent on a new phone to help another person in need directly.

Most people probably don’t contemplate the moral implications of the purchase of a new phone, this is true and I accept your position this. But it is clearly not “literally every person” as you have said, since it only takes a single person with awareness to disprove your statement. I am certain at least one such person exists (even if anecdotally), so I rely on the word “most” rather than “literally every”.

prole,

Ok, but buying a cell phone isn’t the only potentially immoral choice made by people regularly, it’s just one example. Modern life is a minefield with this stuff, and I’m incapable of imagining a person in modern society who is capable of avoiding every single one of these pitfalls. Hell, it could probably be argued that even existing on this dying planet could be considered immoral or unethical. Again, maybe I’m wrong and you could think of one. Maybe some ascetic living on the street in India?

Also, I don’t really agree that awareness is even relevant. You can do immoral things without being aware that the thing you’re doing could be considered immoral. The thing itself is still immoral.

Which was kind of my point; that it’s impossible to avoid in a modern, interconnected world. I probably did a dozen immoral things before breakfast this morning.

claycle,

Bergsons theory of mind. I wish i understood it enough to put a tldr, but its complex and has been misunderstood.

Heres another one. Michael behe’s mousetrap. He likens cellular structure as a mousetrap, with every piece forming a necesesary part, and without any one part it ceases to function.

Back when i was a creationist christian and didnt accept evolution as fact, he was a hero. Endogenous retroviral dna put that all to rest. Except maybe not.

The counter arguments were that other structures could form over time to create the minimalist structures we see today, like using scaffolding to construct a self sustaining roman bridge or replacing the wooden base of the mousetrap with the floor. Obviously behe is mistaken.

But he claims not, that he doesnt argue that variants of mousetraps can’t exist. He argues that all exist without scaffolding. We dont see cellular structures with unnecessary parts that can be acted upon by evolution. Everything already is the end product after evolution has selected away the unnecessary parts. So how can evolution be happening the way its described? We just go between different end products. Theres no structures still with scaffolding.

This keeps me up at night. Maybe theres more to evolution that we dont know yet.

It would have to be Gödel’s Incompleteness Theorem. Such a beautiful proof that shakes mathematics to its core.

Second the Gödel Escher Bach recommendation. Don’t really hear about that one these days.
