Reply #87: I think what he means

is that when you feel something, a response is triggered in your brain (as a function of your senses causing a number of neurons to fire) and coded there and you remember that reponse and can think of that response and recall that response. It's not that this neuron is fear and this one is bliss, it's that when I was scared, I saw this and heard that and smelt something else and so on and thousands of neurons were set off. So a feeling is a recollection of previous experiences, and being an incredible species, we can translate those feelings into unique situations (which is pretty amazing). That allows us to be moved by art or to feel empathy or to be bullied into submission by fear alone. To qualify what I've said above, realistically, we know almost nothing about the specifics of the brain, but we do observe the same areas of the brain being stimulated when we observe something as when we recall it (which leads to the theoretical working of recall I posted above).

As for the gun bullet analogy it really applicable in this situation. It would be like saying that a bullet killed someone versus a chain of nervous system events caused a trigger to be pulled initiating a chemical reaction that led to a physical reaction that propelled a bullet out of a gun and into a person where a series of biological reactions led to the cessation of life.
