    Huge thanks to Neil deGrasse Tyson and everyone at StarTalk!
    It seems easy to know things. The basics of epistemology haven’t changed much since Plato’s time, and we navigate every minute of our lives using a system of justified true belief. If we’re justified in thinking something, that thing is true, and we believe it, then it’s knowledge.
    But as Gettier Problems show us, sometimes that justified true belief model just doesn’t work. We can satisfy every condition of JTB and still not know something.
    So if that system isn’t reliable, then how can we really know anything at all? It’s a philosophical problem so big that we need Neil deGrasse Tyson to sort it out.
    Neil deGrasse Tyson of StarTalk sets the record straight on what knowledge really is. Science, he says, is filled with things we can truly know with confidence. Sometimes they’re things we can count; other times we just hit a limit on how useful knowledge is to humanity.
    The way we view knowledge in our collaborative endeavors sets the tone for how we go about life itself -- and puts us in the best possible position to know more and progress with math, science, and humanity.
    ... and we FINALLY find out whether a hot dog is a sandwich.

      A hot dog clearly isn't a sandwich: It uses only one piece of bread, rather than two, and it isn't sliced bread. Both of those would already, individually, disqualify it. (also, who calls hot dog sausages hot dogs? It's not a hot dog, if it doesn't have a bun. The sausage is either a Wiener or Frankfurter)

      The way i see it, truth is only capital t True when all details and relationships are fully and perfectly explained: anything less than the entire universe, 1:1, is only a part of the truth. Being limited creatures, we can only ever understand small parts of the world, and even then mostly in abstract terms. The incomplete pictures we paint individually, even if we were all perfect reasoners, could still seem to conflict with one another just because of missing information.

      It's the danger between confirmation bias vs. the scientific method. In the scientific method, people try to prove a hypothesis wrong with clear, conclusive tests and do their best to admit the flaws of their tests. Confirmation bias has a person hearing the same opinion over and over by various sources to the point that it feels true. And honestly, its very easy to muddle the logic because we're flawed emotional monkey people. Lol

    Tyson has implicitly defined knowledge as not needing to be perfectly reliable, basically saying we can know things “well enough” to be going about our day as if it’s perfectly reliable. In reality even in cases where we can count things, there’s no way we can 100% rule out the possibility that we’ve consistently miscounted or that the simulation we live in presents to our sense a different number of things than what actually exists.

      ​@@idontcare7961 You clearly are interested in science and scientific methods. You wouldn't be watching this if you weren't and I applaud you for that. Try to disprove your hypothesis with more than one experiment. Get a friend from another country (or even state, if you're in the US) to put a stick in the ground at the same time as you and calculate the shadow length difference.
      Get a telescope (or go to an observatory) and look at the other planets. If they are flat, then it's a safe assumption that Earth is flat as well. If they are round, how come they are all facing towards me? Wouldn't someone in another part of the world see an elongated disk? Also, if it's a projection on a dome, then shouldn't more powerful telescopes be just as useless as less powerful ones?
      Observe a lunar eclipse. If the moon is obscured by Earth's shadow created by the Sun, then it must mean the Sun is on the other side of the disk. Then how come it's day on some other part of the world if it's on the same side of the disk as you? Otherwise, shouldn't the shadow on the moon look differently?
      Also, walking straight from a fixed point in the same direction on a globe Earth and on a flat one should yield different results.
      I'm actually impressed by you for trying to prove your belief in the video you posted, but just like the broken clock in the video, you might not know the truth until you do a second or a third observation.

      John Lucas The Sun’s not going to explode since it doesn’t have enough mass. It will slowly poison itself with heavier elements, swell up to red giant, cast off the outer shell, which will leave behind a white dwarf. So, what can do here that doesn’t included us moving the Earth to another star?
      1- move the Earth out until the Sun passes the red giant stage. Then move the Earth back in close to the white dwarf that our Sun has become.
      2 - Or just lift the excess matter and impurities from our Sun so that it never poisons itself and makes can make more efficient use of its hydrogen fuel. Use the heavier materials for whatever we want. Move the Earth in as the Sun becomes smaller. Slowly add back in, the the excess hydrogen that we lifted from the Sun. Then worry about what to do in 5 trillion year, when our red dwarf Sun begins to turn blue.

    0:11 _"No one can agree on what knowledge actually is knowledge."_
    That is quite a disingenuous way of putting it. That claim implies that most arguments on the internet are educated, sensible arguments on epistemology, when that is far from the truth. In actuality, arguments on the internet are usually between people trying their best to understand something and reason about it on one side, and mass campaigns of disinformation and censorship, and their victims, on the other side.
    It's also very hard to apply "justified true belief" to most internet arguments, since most internet arguments are on political topics of one kind or another. And concrete, solid, full information is something unheard of in the world of politics. Truth is we're all operating on very, very limited data, offering us a tiny glimpse at reality, muddied and distorted by the bias of the sources we're using. The only way of actually making sense of it is by looking at it from multiple points of view. Luckily, there are plenty of people on the internet, with lots of points of view. Unfortunately, most of them are not opened to reason. It is by design that things are so, because the internet would allow the vast majority of humanity to reach some form consensus were this not the case.
    If there's one thing you take away from this let it be this: Seek not those that agree with you, but seek instead those that disagree with you. Don't be afraid of being wrong. Don't be afraid of talking with those that disagree with you. Don't worry about the people that disagree with you and want to talk with you, be worried about those that agree with you and never want to discuss it.

      What you describe works when both parties are interested in actually bettering their understanding, but as you say there are many bad actors looking to spread misinformation. Many flat earthers will use the "You should listen to those who disagree" point to defend their baseless viewpoints by pointing at an endless stream of "evidence" that simply takes too long to refute. People who aren't very skilled at critical thought may be more susceptible to misinformation following that advice. I agree that generally we should strive for better communication, but that relies on some base level of critical thinking and cooperation that I just don't think the majority of people will take part in. It's far more exhausting to constantly think and question and refine what you think than it is to unquestionably accept something.

    I don't know if anyone else noticed, but when the video pans out when he's talking about us knowing we're on youtube, you can see in the title of the video at 5:52, it says ft. Neil Degrasse Tyson, so it spoils the surprise before we know it to be true

    Sounds like we're all wrong in thinking heads OR tails; that's a quantum coin right there.

      If it’s a quantum coin then you’re all right? Unless I don’t understand quantum mechanics at all, which to be fair is completely true

    I guess my question is: "What is the difference between squashed circle and an elongated one?".

    • @jogeem5480
      @jogeem5480 4 роки тому +8

      Maybe if you think about orbital circles a squashed circle would have the bigger mass (say the sun) in the middle of the circle and in the case of an elongated circle, one side would be closer to the sun and the other one farther away. Then the far end would be narrow and the other wide so it's not really "squashed"

      So:
      Squashed circle is wider than higher, because it was squashed from up/downside and than it expanded sideways
      Elongated circle is wider than higher, because it was pulled on sides, what made it to shrink on the top/bottom
      :D
      In other words: it doesn't matter, what is the shape, but description can change basing on the process that made the circle differ from regular circle.

      Wouldn't squashing or elongating a circle make it both squashed and elongated at the same time? Changing perspectives makes it look like both.

    • @landenbarten994
      @landenbarten994 4 роки тому +1

      Maybe when you are elongating the circle, the height of the circle doesn't change, and so it is only the width changing.

    I agree about not arguing about the definition of a word. If someone sees a word differently than I do and I notice I just ask the to define what they mean the long way and I'll do the same. Then accept whatever definition they give you for that particular conversation,. That way you don't let words stop you from communicating the idea and understanding the other person's idea. It's crazy how many times I've seen people argue the same side of an issue using different words for the same ideas.

    Most of the things discussed in the video can be already found in various Plato's dialogues. With some Kant and Popper you can complete the entire video. Scientists believe to discuss new and innovative things but philosophers are familiar with these topics for centuries and millenia.
