But what I am saying is that what we experience (the actuality) is the reality (rather their sum is).
I tend to agree with Paladin here ...
I think you can only speak for you. I'm not sure we can say that any two people experience the same thing
precisely. My mum and my dad have very different thresholds to heat/cold/pain etc., which we have inherited (my sisters follow my dad, I follow my mum), so we have different experiences of temperature. I can happily rest my hand in water that would have my dad howling ...
I know what you mean by internal and external, but in the end, everything is internal — it's a construct in the mind fed by the senses.
The Quantum experiment you mentioned, I as a kid did the same thing with two pairs of polaroid glasses, but never got a fraction of the understanding that you have, it was just fun that the glass went dark — so your actual in that instance is a far greater and far better informed actual than mine.
I see and know of no evidence for "real stuff" beyond actualities.
I think that's over-stating the case. I think scientists (etc.,) see evidence for further 'real stuff' in the real stuff they look at, where the man in the street sees no evidence of anything beyond the immediate actuality he's looking at.
I remember listening to a talk by the guy who invested the Fiery RIP for image processing. He got the idea by watching someone making photocopies. He had all the science in his head by the time he got back to the office, and the key was how long it took to scan the image ... Now, I've waited in the queue for a copies, and all I saw was how painfully bloody slow the thing is, when you're in a hurry.
But my point is Efi Arazi saw a 'real possibility' in a given actuality, whereas most other people just saw a photocopier ... ?
Surely Quantum Phenomena was not 'real' two hundred years ago?
Does not science proceed by positing hypothetical 'real stuff' and then working towards proving it?
Science has opened up vistas of that which was 'unreal' a few generations ago, technologies unlocking the microcosmic and the macrocosmic ...
Then take that picture of planet earth, taken from Apollo whatever ... many commentators said it has 'changed our reality' about the way we perceive ourselves and the world.
Good ol' Eriugena, in the 9th century, in his "
The Division of Nature" posited that nature is defined as
universitas rerum, the 'totality of all things', and that the first division is into those things which are (
ea quae sunt) and those which are not (
ea quae non sunt).
The key, and the breakthrough — a full thousand years ahead of its time — was that Eriugena posited the human subject is the perceiving object upon which all our conclusions are based.
So the first division is between those things that are perceptible and intelligible, and those things that transcend normal perception and intelligibility.
Surely to say that there can be nothing that transcends the human senses is, I suggest, something of an over-statement?
Don't know if this helps, just throwing it in there ...
... but enjoying the thread so far, so don't let me side-track you.
Just a closing thought – the problem is, of course, we use science, we use empirical methodology, but as creatures we're way more than that, we seek not only to understand what things are,
but what that means, and that goes way beyond the empirical data...
