Jgnat. I think we're getting closer to some concensus.
Simple analogy: You see a light bulb, it is lit, by what means does it manifest light? Of course its by sensing(reacting)to a remote source. That source is the switch. The switch is not the sensor, it is the signal upon which the sensor the bulb reacts, if the bulb is not lit and the switch is in the on position then there is no light why? Because the sensor is inoperative.
By the same means (circuitry)although much more intricate the brain reacts to or senses the signals.
Those signals or switches; pain , sight , smell etc are picked up by the main sensor the brain. That is why under anaesthetic the brain(sensor) is tricked into not reacting to the affected switches even if they are being activated.EG tooth extraction, surgery etc..So the conclusion must be brain is the sensor upon which the drug (anaesthetic) is acting upon.
Anyway back to topic: Heart vs mind what makes us human? I admit my contribution was by way of going back to our early formation which essentially and fundementaly is what makes us modern humans. My reasoning was contrary to Ballistic who seemed to say were creatures with feeling first then brain thought after.
Of course I'm not sure what stage of creature he was referring to perhaps he is talking about contemporary man?
In that scenario I would still take the opinion that without the brain there is no emotion , instinct or any other function. Essentially IMO it is the development of our primitive nervous system into the complex circuitry of which the brain is the main cluster that makes us human.
