Yes, obviously with the 'in principle' caveat: — Kenosha Kid
Yes, of course.
I guess I'm just not seeing the relevance of masslessness. — Kenosha Kid
It's only massless particles that are lightlike, and so have an existence that (from their frame of reference) consists entirely of the interaction between what emitted them and what absorbed them.
This might be off topic, but one thing occurs to me. When we interact with anything, it is overwhelmingly electromagnetic in nature. When we see a tree, photons emitted by that tree are destroyed in our eyes: this is sight. When we feel the tree bark, virtual photons emitted by the charges in the bark are destroyed by charges in us: this is touch. We never destroy charges, only the emissions of charges or systems. — Kenosha Kid
Yes, that's something I've been assuming as background knowledge in this thread. Glad you explicitly pointed it out though.
:-)
I guess that's why I find the primacy of mind and experience in your language (and I think that you do not distinguish between the experience of a person and of an electron) a bit of a barrier. — Kenosha Kid
I see the experience of a person as a special subset of the experience of an electron. "Experience" here can be taken as equivalent to QM "observation". When a human observes something, they are still doing the thing that an inert object merely interacting with it does, that causes (or is) wavefunction collapse or entanglement or the splitting of worlds, however you want to interpret it. But a human is also doing a lot of other stuff that an electron isn't doing. That other stuff isn't metaphysically important here, it's just brain function, more complex information processing, but it's a thing humans do that electrons don't.
In your literalist interpretation of the creation/annihilation operators of QFT, it is the fields that destroy electrons directly. (The Higgs mechanism is the destruction of an electron with one isospin followed by the creation of another with the opposite isospin. The motion of an electron is the destruction of the electron at one position followed by the creation of an identical electron at another.) — Kenosha Kid
Yes, although not all motion can be reckoned like that -- specifically, the lightlike motion of massless particles can't, because from their frame of reference they travel zero distance in zero time, so motion is irrelevant. It's only massive particles, which already consist of a "blending" of several more-fundamental massless particles through their constant annihilation and recreation by the Higgs field, that can be construed as moving through a series of annihilations and recreations; because it's precisely that series of annihilations and recreations that gives them mass, and makes their motion slower than light.
Somehow this makes me think of the sort of equivalence between experience and objective reality you're getting at without necessarily being the sort of thing you had in mind. — Kenosha Kid
It sounds like you're on basically the same track as me, to me.

If you are not an idealist, then you must hold that there is unexperienced information. If you hold that all information is experienced, as you seem to be saying here, then your position is idealist, not realist. — Banno
I am not saying that all information is experienced, but that all that exists is the
kind of stuff that
can be experienced -- whether or not it actually
does get experienced. That kind of stuff can be characterized as information.
My own worldview is best defined as both Empirical Realism and Transcendental Idealism — Gnomon
In Kantian terms, any empirical realism is also a transcendental idealism, and conversely any transcendental realism is an empirical idealism.
An empirical realism is a view that takes the stuff we can observe, phenomena, to be the stuff that is concretely real, and conversely the transcendental, unobservable stuff, the noumena, to be only abstract ideas. My account of the "objects of reality", the nodes in the "web of reality", being abstract mathematical functions, which we infer from their behaviors that we experience in response to other behaviors they experience, accords with this.
An empirical idealism, on the other hand, would hold that the kind of stuff we can observe, phenomena, are just abstract ideas in our minds, and conversely that actual concrete reality is the transcendental, unobservable stuff, the noumena, that underlie those phenomena, and which those phenomena represent to our minds. That's a view that both Kant and I reject.
Science does not give us any evidence that all real things can be experienced, so how did you arrive at that conclusion? — frank
From the practical reasoning that if we ever take any claims to be beyond questioning, we simply stop searching for the truth, and so are likely to never find out if we are wrong, so we must not ever take any claims to be beyond questioning; and that claims about things that are not subject to experience cannot ever be shown wrong (because we could not tell whether or not they were, because we have no experience of them at all), so we could only take such claims on faith, without the ability to question them; so we must not ever entertain the possibility of things that are in principle beyond all experience, for in doing so we would be giving up our pursuit of truth.
And it definitionally cannot be shown that there does exist something beyond experience, because to show that would be to make it available for experiencing, so we don't have to worry about ever finding our assumption that there is not to be wrong.
