I actually don't think this is that difficult.
First, think of when you first realized how evolution worked. Before, it seemed unbelievable that the fantastic complexity of life could have developed "on it's own". But then you grasp the concept of natural selection, how a series of small genetic mutations can be selected for and increase the complexity of a species. From there, it's just a matter of imagination to embrace the idea that all life evolved. For consciousness, we have the model of software. I remember seeing a robot at the MIT Museum that was described as the "first to recognize itself" in a mirror. Imagine a robot that formed a continuous model of the real world, that continuously identified objects and its place and interaction with that world. From there, it's just a matter of imagination to embrace the idea that consciousness is just really complicated "software" running in our heads. There is really obvious empirical evidence of this. Bash your head really hard and you lose all or part of your consciousness. Take drugs and your consciousness changes. Stick electrical probes in your brain and you can stimulate thoughts and feelings and memories. What we're missing is a basic understanding of how the brain operates. How are memories stored and retrieved? How do we calculate the trajectory of moving objects? How do we recognize and retrieve language? My guess is that there is a basic type of computational element that is adapted to all these different functions, but I'm not a neurologist. Finally, it's a total cop-out to call anything "supernatural", as has been noted in other responses. I totally don't buy the "we'll never understand consciousness" comments. We will, once we crack a few tough problems. |

We know yes the brain affects consciousness and mind but the mind and consciousness also has an effect on the brain through meditation, neuroplasticity which has been demonstrated by Dr.Sharon Begley, Dr. Jeffery Schwartz, Dr. Mario Beauregard, Physicist Henry Stapp. For the production theory to work brain can only affect mind but mind can NEVER effect brain. |

I don't think your world view is as far from mine as you think it is. I presume from your statement that you believe God created life, and that there is some supernatural component to consciousness. Let's respect the topic of this thread and skip the evolution debate for the moment. So let's assume there is some supernatural component to consciousness. What does this component bring to the table? Is it my mind, fully conscious and aware as I am right now? Somehow separate from the physical world? If so, it is tightly bound to the brain. Here are some questions I have for you: - What is this component doing when we're young? A fetus? Why can't we remember that time? Why does our thinking capacity seem to mirror our brain growth? - Why do we get drunk, in the sense of how can alchohol affect a supernatural component? - Why does deterioration or damage of the brain seem to mirror the function of our consciousness? First, do you agree that all of these things happen? That the function of our consciousness seems to closely mirror the physical condition of our brains? If you're with me so far, then there is only a small difference in our world views. Because a "supernatural component" that is so tightly bound to the real world is hardly "super"-natural. I do think it's interesting that people believe that there is this supernatural piece of us that is separate and complicated, then shrinks to almost nothing when we're conceived, grows in awareness with our growth, then deteriorates with our deterioration, then suddenly pops back to maximum strength when we die. |

The point of having consciousness is that it provides a complex control mechanism for the body, that has tremendous survival value. I think "move my arm" and my arm moves. I close my eyes and imagine the object of my sexual desire, and all sorts of changes happen to my body. The mind can effect all sorts of changes to my body, and these can NEVER effect my brain? Come on. |

Another trivial example. There are "field programmable arrays" used in computers. These arrays can change their hard-wired connections based on voltages applied to their pins. Install one of these in a computer, and the software can change the programming of these arrays to more efficiently compute.

What is the definition of consciousness being used here (on this thread)? Is it strictly self-awareness, or our so-called higher reasoning - considering that we are learning more about other animals and we keep finding things that were once considered a product of consciousness (tool use, limited language, waiting for a larger reward - time keeping, etc), what exactly are we talking about? |
