The difference between a life form and a mixture of chunks of coal and water won't be found in comparing the chemicals, the difference is in their organization. That is all that separates living matter from non-living matter. Mechanism says the same thing regarding intelligent entities vs. non-intelligent entities. It comes down to their organization, not any material difference. Addition can be performed by collections of cells and by logic gates etched on silicon. Most neurologists consider the retina part of the brain, since processing is performed there. Could we not build an artificial retina which sent the right signals down the optic nerve and allow someone to see? Such cyborgs already exist: http://www.cbsnews.com/8301-504763_162-20038162-10391704.html > My alternative is to see that everything > has a private side, which behaves in a sensorimotor way rather than > electromagnetic, so that our experience is a massive sensorimotor > aggregate of nested organic patterns. > > > A computer flying an airliner is not very smart, but it would know what > > a runway is, what a storm is, the shape of the Earth.

If you are going to use reductionism when talking about computers, then to be fair you must apply the same reasoning when talking about minds and brains. > A computer > autopilot knows less what a plane is than a cat does.

Do you need another person to look at and interpret the firings of neurons in your brain in order for there to be meaning for your thoughts? If not, why must be a user of the computer to impart meaning to its states? Jason -- You received this message because you are subscribed to the Google Groups "Everything List" group.
