Yep! I think you're switching things around on me here, (*) but okay.
"By heat, do you refer to the intuitive idea of heat, which
was envisioned as the source of the feelings of warmth and so on?
Or by heat, do you refer to what we understand as the physicality
of heat, the staccato motion of atoms? Which is it: the idea,
or the actuality?" I interpreted your first one as talking about the
physicality of heat, vs. the motion of atoms, (no difference,) whereas
if you switched it around to "no, the idea," then there's a ton of
difference, producing an explanatory gap, which then demands
justification. Such a justification follows.
OK: So, in **that** case, we have two things:
* "Heat," as intuitively understood by humans:
- it feels more than warm,
- we see it around fires,
- we'll call this "sense-heat,"
* "Heat," as the manifest motion of atoms.
- we'll call this "atomic-heat"
What's special here, is that we know and perceive both
sense-heat and atomic-heat.
And THEN, we have a **story,** that links the two together.
That is, we say, "Okay, whenever there is atomic-heat, we notice
sense-heat, and wherever we notice sense-heat, we notice
atomic-heat. And further, we understand the mechanics whereby,
when you touch or get near atomic-heat, the cells are influenced,
and signals communicate to nerves, and the signals travel from
the nerves to the brain, where it then registers atomic-heat."
See? We have the story, connecting the two different ideas?
And that story, it relies on the electromagnetic force, primarily.
The reason why the molecules jump around and repel from one
another: electromagnetic force. The way that the signal
communicates up the nerve: electromagnetic force.
Hardly any contribution from strong, weak, or gravitation forces.
It's all electromagnetics. So the root of our story, about the why
and the wherefore, connecting the sense-heat with the atomic-heat,
And thus, it lies explained.
The problem here, is that we have two phenomenon, which are
different, "the subjective experience," and: "the neural correlates
Make no doubts that these are two completely different conceptual
things: We can easily conceive of awarenesses floating in ether,
dreaming up stories, without any correlates at all. (Regardless of
whether we believe in it or not.) And we can easily conceive of
neurons, doing their thing, but without any actual inner experience
of consciousness; Merely rote calculation and transmission and
chemical influence and so on.
Between these two things, there lies an explanatory gap.
It is not filled.
