    I'm not a scientist, and I'm not familiar with something as complex as science, but I like the fact that he made us remember what curiosity feels like. That whole ''I know that I know nothing'' that Socrates said.

    I'm surprised he didn't mention the fact that visible light is just electromagnetic radiation, which technically is invisible as well. We actually exist in pitch, stark darkness. The only reason we can "see" anything is because our brains are able to take the electric signals generated by the rods and cones in our eyes that are energized by certain electromagnetic wavelengths, and then turn those signals into an "image". But the image itself exists in our mind, nowhere else. Everything we see is just a perception of what is actually there, and everything that is there is there in utter darkness. We just see energy reflected off the objects, that's all.

      Yes, this always bugged me. he knows that he knows nothing which means that he knows at least that, which is not nothing. But years later I think he meant something like "There is so many things to know and I know so little of it that it is almost as if I knew nothing." Or maybe that he knows stuff but he only thinks he knows it and it can be totally opposite of what he knows thus he can know nothing for sure.

    • @ElizaMogha
      @ElizaMogha 9 років тому +3

      There appears to be a paradox there. He did mean, though, what you suggested first: he came to a realisation that there is such a wealth of knowledge out there that we/he know only a fracture of, so it's almost as if we know nothing, it's that little.

      do you think that's the only reason were here? I mean we do only experience what we go through and have some sense of free will. but when were gone, wtf happens? GONE! or are we? so crazy to think of that. forget who said it but.... coincidences are gods way of keeping Himself anonymous. I like what you said about the events that lead you places. I'm a strong believer in that we should be respectful and patient with most people because in the end they didn't chose to be born where they were born and the events they go through as infants. never the less all this affects them for the rest of their life and they I a way become results of those circumstances. It really destroyed my Christian beliefs because I asked myself, why would God judge people if they ultimately didn't have much choice? lately ive been thinking we are all just animals and the only thing that makes us better than an animal is the quality of education we receive. in the animal kingdom there is a hierarchy and there are pests and exotics and meat eaters and herbivores and everything in between. maybe the human species is just another animal and that's why its ok to lock some animals in a cage. idk just a long ramble. but yeah funny how one of the most rewarding things a man can do is help someone out.

      I don't like life. In the matter of fact, I despise it. It's a very bad idea that brings more bad than good. A rock can't suffer and be unsatisfied, it can't be born and then abruptly die, whence life bloody can and it's pretty much everything it does. If we can do anything it's help other life forms to suffer and be unsatisfied less. Buddha said there is a way to end this bullshit, but it's a damn hardcore one, despite being crystal clear and as simple as it gets.

      King Kitteh I think you are taking it out of context. Don't think he meant that as an "edgy" thing. Just as light can show us certain things, it can also hamper our vision and take things away. Stars, certain creatures, etc. People often conclude this with night time, but to a lesser effect daylight can do the same.
      but at its base, as people already have mentioned, blinding lights are the best example.

      That is literally the definition of invisible. "In-"="not", "visible"="able to be perceived".

    • @SpcGiraffe
      @SpcGiraffe 8 років тому

      ABunchOfRandomAnons Just because you are not perceiving something at that very moment does not mean you are unable to perceive it.
      If I am standing behind you not saying a word and you don't know I am there then I am only invisible in your perspective, but I am not truly invisible, simply your perspective is wrong. If applied on a grand scale then every perspective is wrong even the one which perceives that every perception is wrong.
      Since we have reached a paradox this is where most people get stuck. But what the paradox shows is that everything is both and neither wrong and right, visible and invisible. That it depends on the eye of the beholder; that the more that is visible the less that is invisible, and the more than is wrong the less that is right. This is the understanding that the most basic foundation of all (non-pseudo) sciences are based upon. That when we observe something change we are actually observing how our perception changes in response to a perceived change: how our perception changes our perception.
      Anyway, through understanding this we can understand that it is impossible to be truly invisible unless it is impossible to be perceived even by yourself. This is the equivalent of being dead and this is where my understanding hits a brick wall as I cannot perceive whether I can still exist if I cannot perceive. I imagine I would need to perceive myself in such a state to gain an understanding, and so we've reached another yet more complicated paradox: To perceive myself in a perception-less state.

    • @definitelynotafurry2503
      @definitelynotafurry2503 7 років тому +3

      That depends on the definition of stupidity. If stupidity is not knowing things (facts that can be memorized) then an artificially stupid machine is easy to make, just don't program it at all. If stupidity is being able to memorize facts but not knowing how to apply knowledge (like knowing that 1 km = 1,000 m but not knowing how to convert 0.7 km into m) then it would be slightly harder to program a computer to be artificially stupid. If you define stupidity as making bad choices with shaky reasoning (like you threw your rubber duck into the river because ducks live in rivers) then it would be very hard to program. We have plenty of examples of human stupidity (signs warning that there is a sign for example) that suggest the last option.

    • @umnikos
      @umnikos 7 років тому +3

      Rachel the gosh-darn human​​​​ stupidity - behaviour that shows a lack of good sense or judgement.
      Seems like the last one. Yeah, I think it's easier to make artificial intelligence than artificial stupidity. The main reason for this is that people understand logical decisions more easily than illogical ones.

      yes , we are invisible at metaphysical level, the subtler we would see, the matter will disappear , actually matter exist at only that level of frequency which is compatible with our human body frequency ,rest things are waves in this universe which is incompatible with our body frequency .
      where the science of physical world stops working , the journey of spirituality starts from there ,we should switch our mental perspective from physical to metaphysical............this is the only gateway to know.

    The answers to all those questions can be easier to figure out if we consider that there's a GOD that made it All possible. There are many things that we can't see, like gravity and the space between planets galaxies and stars in the universe that exist so we can exist (live). So if we can't see God does that mean that he doesn't exist??? And if we look closer to humans behavior compared to other living things, we are the only ones who have created religion which means the we need someone higher than us to follow. Why??? Easy... Its because God created us spiritually different from the other species. But humans got away from him spiritually because of sin. So actually, depend on Him in every single thing. And yes there are many thing bigger than this earth, like stars that make us look like nothing. If we look at the bible it says about how mighty is God because of all the stars and the matter in the universe that He has created. It's because of his amazing power. And yes He's capable of create something millions of billions bigger things than thins earth and much more. Why something bigger than us. I don't know. But all I can tell you folks I that His way of thinking is higher that us, and impossible to understand by our own little knowledge of how things work. And if He is the Master of everything SEEK Him and you will find Him, when you're alone, hurt and asking yourself if you really exist. Because He Gave His life up so you can be closer to Him again.

    • @__Paprika
      @__Paprika 9 років тому

      we can't see it so we can't prove it doesn't exist. But we can't see it so we can't prove it exists either. So god remains an hypothesis that cannot be verified. We don't reject it but we cannot say it's true either.
      My personal opinion is that it's something we made up to explain stuff we don't understand, and that satisfies our minds : we like to understand how stuff works, and when it's too complicated then an easy solution is to say "well there's a god that does it all and that's it".
      So even though i don't believe at all in a god, i find it pretty natural that some people do, it's a rassuring thing and everyone likes that.
      But saying that god made the earth in x days, made the life, made this and that and whatever, that's just ignorant and disrespectful for scientists because, unlike god, evolution, geology, and others science branchs are funded on solid and irrefutable proofs

    that's fine that your agnostic and whatever, but you didn't have to insult other people's faiths. what's with atheists and agnostics putting down Christians? nobody is *forcing* you to worship and believe in Jesus. if the Bible offends you that much, then you must be harboring something of greater evil in your heart.

    A lot of scientific errors in this, much of it quoting old research. In particular the psychoanalyst comment.

    "Sufi" is not a "great middle-eastern religion" - rather Sufism is a sect of Islam, practiced in Turkey, North Africa, India, Indonesia, and many other countries, not only in the middle east. Another thing: Sufism can not be the "root of all religion", since Islam itself was invented in the 7th century.
    p.s. aren't these Ted lectures supposed to be smart?

      Nusrat5791 Pssst, this is about science, not religion.
      The guy was making a point, not saying that only to grab his popcorn and sit back in glee and see the religious arguments unvail before him.

      +Nusrat5791 yes you are right and Sufism is derived from the Islam. But Islam wasn't invented in the 7th century, it was invented by Abraham peace upon him and completed by Muhammad peace upon him.
      And what Islam means : "Say, “Surely my prayer, and my rites, and my living, and my dying are for Allah, The Lord of the worlds. No associate has He; and this I am commanded, and I am the first of the Muslims.” (Literally: of the ones who have surrendered to Allah).” verses 162-163 surah Al An'am , Holy Qur'an
      and what Allah means: "قل هو الله أحد(1) الله الصمد (2) لم يدل ولم يولد (3) ولم يكن له كفوا أحد (4) " سورة الاخلاص
      "Say, “He is Allah, The Only One (1); Allah, The Everlasting Sovereign (The Arabic word is sometimes taken to mean all that is mentioned in verses 3 and 4) (2); He has not begotten and has not been begotten(3); And to Him none could be co-equal.(4)” Surah Al Ikhlas, the Holy Qur'an.
