       | if "The whole is other than the sum of its parts."

       | Consciousness cannot be understood or known in the

       | sounds very hand-wavy and esoteric but if you think hard about
       | it, it is absolutely and undeniably the only tenable logical
       | position.
       | 
       | Put in another way: if you somehow claim to be able to observe or
       | measure consciousness as an object, then what is it that is doing
       | the observing?
       | 
       | Similarly, consciousness is unchanging and without beginning or
       | end, for noticing and knowing any change you need consciousness.

       | The article poses this question, but leaves it unanswered.
       | 
       | For me it begs the question: If conscousness is bound to a

         | 
         | From what I can best tell, consciousness is a property or a set
         | of simulated properties, I don't really know what it is and I
         | guess we won't have good answers for it until we will be able
         | to properly simulate something like a brain and have better
         | brain theories to explain it.
         | 
         | But the world you find yourself is a simulation, and your body
         | is simulated. Everything you consciously experience is
         | simulated. This simulation is running inside your brain. Part
         | of your brain is trying to explain its input so it makes models
         | to predict its inputs. I think it learns a model of your body,
         | and your mind, and how these thing relate to each other and how
         | they relate to what you experience "out there".

         | Yes. (I think so)

         | This is only fascinating if you refuse to accept a non-

         | Otherwise, most of these questions become trivial when
         | consciousness is considered as a physical, biological process
         | bound to the brain.
         | 
         | Why is consciousness bound to a person's location? Because
         | their brain is bound inside their skull.
         | 
         | Why are you inside your body and not someone else's? Because
         | your brain is inside your body and not someone else's.
         | 
         | Is it possible to transfer consciousness from one entity to
         | another? _transfer,_ no, because consciousness is inextricably
         | linked to the brain. There 's no separation between the
         | hardware and the "software."
         | 
         | What happens when you die or someone is born? Nothing. No
         | afterlife, to karma, no reincarnation, no bardo, nothing.
         | 
         | And finally, are those questions even answerable?
         | 
         | Yes, I believe they are, but many people are uncomfortable with
         | the ramifications of the answer as best supported by available
         | evidence - we are purely physical beings existing within a
         | purely physical universe. Despite all of the evidence from
         | biology, neurology, chemistry, physics, etc. failing to show
         | any credible evidence of a supernatural or non-biological
         | component of consciousness apart from the brain, many people
         | keep hoping someone will discover the soul someday and be free
         | of the prison of material reality.

           | 
           | What if we can transplant the brain itself? The consciousness
           | is still contained in and created by the same brain, but
           | every other part of the experience (sensory input) are from
           | another body _effectively_ transferring consciousness between
           | bodies.

             | The definition of supernatural is that which exists outside

             | tangible. Natural laws are human-created abstractions which
             | explain the observed behaviors of the natural world, which

               | Natural laws exist without humans, unless one believes

               |

               | Natural laws are observed within nature, which makes them
               | a part of nature. To claim that natural laws are
               | supernatural simply because they're abstractions, and

           | I'm not arguing for a soul or something. But I find it

               | 
               | So my theory is that consciousness is the emergent
               | property of many separate specialized brain areas
               | responding to and interacting with each other: either
               | directly (neuronal links), via the body (flexing a muscle

               | through the world (turning your head changes what your
               | eyes perceive).
               | 
               | So speaking in terms of functionality, there is no
               | "brain" as a single entity. The brain is like an ant
               | colony, using hormones and electrical impulses to keep
               | its disparate parts acting in unity. Under this model,

               | these parts, and self-awareness as the consensus model
               | under which the separate parts reached some equilibrium.
               | You won't have problems defining which parts do the
               | observing and which parts are observed: what we

               | processing areas, not the processor activities
               | themselves. And similarly, what we experience as
               | consciousness is the ability of our "mind" to drown out
               | that cacophony and purposefully cede control ("focus") to
               | different brain areas at different times.
               | 
               | Of course, there's no evidence that any of this is true,
               | and there's still plenty of questions about the mechanism
               | through which this would happen, but for me personally

       | 3) Claims that we cannot understand consciousness. Usually these

         | evolved consciousness as an evolutionary advantage.
         | 
         | Being exposed to your internal and external environment is the
         | source of consciousness. Even a single cell can seek nutrients
         | or avoid bad places, or decide when to replicate, it has a
         | rudiment of consciousness. But panpsychism? It's one step away
