All of that makes sense, but pain is more than unpleasant. Pain can be blindingly horrible... ask any migraine sufferer. What accounts for the intensity of such experiences? I'm asking this in terms of "how", not "why".

I have the same issue with this description of pleasure.

I chose orgasm because of the simplicity of its conception in terms of evolution and adaptation. In other words, it seems possible that any animal that reproduces might experience pleasure in the act of doing so... in some theory of mechanistic pleasure yet to be articulated. > I wonder if we could one day develop implants or software which would let us > break down our feelings/qualia into simpler parts so we could better > understand what they're made of and what they're caused by.

I mean, for qualia like color I am completely OK with mapping that to the correlative 3p mechanism involved with processing retinal input, broken down by differing wavelengths.

Again, I'm trying to keep this as simple as possible. For instance, do you believe that there's a class of animals that do not have emotions as we are discussing them, but still can perceive pain or pleasure? This seems very likely to me that there is such a category of animal. If so, how would you characterize it's cognitive architecture, as distinct from the animals above it that can experience emotion, and the animals below it, that can't feel pain/pleasure?
