If we lived in a universe where without exception every single time there was a traffic jam then "obviously" the laws of physics and the orbital mechanics of the solar system would have to be radically different from what they are in this universe. And if we don't have a good theory to explain how it could be that traffic jams could effect the rotation of the Earth that's just too bad but the universe doesn't care if we understand how it works or not and our lack of understanding would not change the fact that the every single time a traffic jam happens the sun goes down. >> we know that whenever there is a change in brain chemistry there is >> ALWAYS a change in consciousness and whenever there is a change in >> consciousness there is ALWAYS a change in brain chemistry, so consciousness >> and chemistry are also inextricably linked together. >> > > No. > NO?

That signal is excitatory pushing in the direction of a sneeze, and for every excitatory signal there is almost always a inhibitory signal saying not to do it, one signal will be stronger than the other so you will either sneeze or not. Should we inform CERN that pollen does not obey the laws of physics, or histamines? > Receiver theories of consciousness are not my invention, and have been > around longer than Newtonian physics. Yes, and that is an excellent reason for thinking they're bullshit, just like many ideas from the pre-scientific era. > A computer can be programmed to detect what it is programmed to detect. > It has no idea if your microphone is providing it with audio input - input > is input.
