Do we truly know anything?

this is a pretty straight forward question is there anything (examples wanted) that we truly understand everything about down to its smallest components?

That allows one to be certain that there is nothing of which one is not aware, or, to put it another way, to be sure of what cannot be known. No human can ever be sure there is not some unnknown they have failed to consider. Thus we have phrases like: "as far as we know"; "according to available data"; or "logic dictates that. . . "

    Apr 4 2013: Yes. Because I know I like Fried Chicken.
    • Apr 5 2013: yes but do you really know what fried chicken is?
  • Apr 8 2013: That is evolution. A man that learned to drive so well he can do it perfectly without thinking has acquired his car almost as its a limb. A man that can play the piano without thinking has evolved.
    So, I dont think we need genetic engeniering. It may help. But we are already evolving every day anyway.
    And no, I still dont think that will enable us to understand everything of something.

    I also believe once you understand everything you become god. But I also doubt one day we will be able to achieve that. At least as humans anyway.
  • Apr 8 2013: I think humans are evolving on its own through diferent means. I mean, evolution as a biological concept has its flaws. Its also logical to observe that humans nowadays are very diferent from humans from 100.000 years ago. Not only due to biology but also due to technology and knowledge.You see, we usually see our bodies as a single entity. But it really isnt. Our body is a ever changing organism made of billions of cells, which sometime last a few days. Due to our neurons, we are able to retain memory, and are able to create an ego because we can maintain information. But that doesnt change the fact that our body changes every single day. The man you are today didnt exist 1 year ago. The matter changed. The physiological laws inside your body changed also.
    What made humans diferent is that we understand causality. Causality being the knowledge about how things change from one thing to another. Its the understanding that water turns into ice, that if you drop something it falls. Its understand natural laws. Our body uses these natural laws to make it work. We, as humans, undertand laws of nature to change the enviroment. So, when a man learns about causality he is, in some way, evolving. Just like some animals that gather shells from other animals and use it for their own reasons, we as humans also adapt natural laws to our bindings. That means we have conquered eletricity, chemistry, the power of the atom and nuclear energy, gravity and so own. Just like our bodies use causality in one way that evolution "enabled" it to, we as humans are evolving because we are gathering more and more powers through the use of technology.
  • Apr 5 2013: I can only hope that what we know barely even registers as a fraction of a percent of what we potentially could understand.
  • Apr 5 2013: It depends on how you aproach reality. Human perception is flawed because if you dont believe in god you also dont believe the universe was tailored for us, meaning instead of a universe that was laid down for us to understand it, we are merely lower life forms strugling to understand a bit of the universe that is avaiable to our perceptions.

    So, there are two paradigs: the universa was made for us, which means we can truly understand everything about it, or we are just a part of the universe, and are strugling to understand part of it through our limited ressources.

    I believe in the second idea. Now, people say we have five senses. Those are the ways we can perceive reality. For example, light is the perceive spectrum of certain eletromagnetic waves that can be transformed into neurological impulses through our eyes. Yet we are able to perceive waves that cant be seen through our eyes by using technology. Technology enabled us to experience things that we wouldnt be able to with just our natural senses.

    Now, has technology enabled us to perceive every single detail of something down to its smallest components? I doubt so. Will we be able to in the future? I also doubt it. There are probabily truths in the universe that we humans will never know about, no matter how much science and technology develops.
    • Apr 5 2013: Yes this is very true.. now i truly believe that there is a point when technology is so highly advanced you simply become god but humans as the species we know will not. Also for all we know in 300 years genetic engineering will have changed us into an entirely different species.
  • Apr 4 2013: No. Because there is theory of probability.

    If you look at this way, the Mayans were a very brutal people a few hundred years back but they devised the Mayan calendars amongst other things, with all our warring, destruction & polluting are we going to be seen in the same light in a few hundred years time? I would say so, so how far have we really come & how much have we truly learnt?

    Let's look at the combustion engine for an example which was first devised in the late 1800's, we are still using the same although modified version of the original combustion engine, it still works on the same exact principles today which really shows you how antiquated we still are in our thinking.

    We know diddly squat.....Sorry, we have devised more efficient ways to kill our selves off, that's progress for you!!

    Apr 2 2013: Yes. I truly know I do not know many things. I have a feeling many of us know that too.
  • Apr 2 2013: I never think I can truly know everything.On the contrary all things I think I know just the tip of the iceberg.For an instance:Sometimes you think you do know one of your friends well,but someday you just really have quite different ideas about what your friend is...Now I know it is so common in our lives,it depends on what my perspectives to see things around.

    Apr 1 2013: Trigonometry is a limited field of mathematics. It has been thoroughly explored and we understand it completely down to it's smallest components.
    • Apr 1 2013: Congratulations, you completely understand pi down to it's smallest components.

        Apr 1 2013: Pi is exactly circumference / diameter. Just because it can't be expressed as a fraction doesn't mean it's not understood.
        • Apr 1 2013: No argument. This whole discussion is about "understood."

          If anything is completely understood, it is mathematics. We have a better understanding of mathematics than we have of our language, and we have specific brain structures for language.
        • Apr 1 2013: yes but also you must understand we don't know the exact origins of the most basic math
