It does mean that a machine can't behave just like a living thing, because everything that a machine is, and everything that a living thing is, are behaviors and experiences. You can't assume that two completely different things have the same behaviors and experiences just because the behaviors that you think you observer seem like what you expect. > > What I'm saying is completely different.

That's an unfounded assumption. Conjoined twins have the same genetics and environment yet they are different people with different personalities.

Ugh. There is no such thing as conscious like behavior. Again. That is my point. If I am a cockroach, then cockroaches seem to behave like they are conscious to me and human beings are forces of nature. I can only think that this insight is not accessible to everyone because only some people seem to be capable of getting it and just overlook it over and over again. It is critically important to understand this point or everything that follows will be a strawman distortion of my position. So, does cockroach-like behavior mean that a machine is a cockroach?

You can't prove that you have consciousness but you are going to prove that something else has your consciousness because it acts like you do? >You need to be able to follow > the proof in order to point out the error if you don't agree.

Neither brain states nor mental states are finite or bound to each other explicitly. Some are bound explicitly, some are not.

So you would find it no different whether it is a lifelong friend who has been betraying you for 20 years versus a robot who was programmed to extract business intelligence from you from the start? You would hold the robot personally responsible and not GoogleBook? Craig -- You received this message because you are subscribed to the Google Groups "Everything List" group.
