The light is in our eyes...

Just to clarify...

the following image although for all intents and purposes quite correct, can be misleading:
View attachment 1460

It shows the reversed image on the retina and the source.

yet the following image describes all we actually experience:
View attachment 1461

According to well understood theory, we do not actually see the source we only see the light that the source emits. ( on our retina)
How are we able to say we are seeing the source?
How do our light effect models allow for us to see the source (at location, "over there") even if historical ( ie. astronomy).

BTW apologies for any confusion as I am trying to find out how to ask the question.
images taken and modified from posted video as we go...

Think I mentioned this before BUT the image depicted in the eye is wrong

Upside down - Correct ✓

Left to right transposition - not present so wrong X

Can you please provide a link to the source of the illustrations?

Many check out the following link

https://books.google.com.au/books?i...n the retina transposed left to right&f=false

I'm not sure if I would like the link to clarify your thoughts

or confuse you

I will work on my dilemma

It is science that is saying that 8 billion unconnected individuals can share an enormous amount of uniformity in their "rendering" of 4 dimensional space not me...
Science is not saying that; 8 billion people individually are saying that.

"I see a red car. What you do you see?"
"I see a red car too."
There's no conspiracy here.
 
ok so we agree that the brain has to somehow interpret the 2 dimensional info and somehow extrapolate it out "there" for us to gain the illusion that we see the source in 3 dimensions allowing for constant change ( time)
Yes.

In fact, the ability to usefully interpret the images we receive as a source of 3-dimensionality of the world is a learned behavior.

Experiments have shown that it can be hacked - subjecting newborn animals to illusory geometries renders them unable to perceive the world as 3-D (simplistically).

YOU have just claimed the existence of a well understood theory

Can you please provide a link to some sort of publication which details this theory and how it was demonstrated?

Thanks

Science has effectively locked us all in a magical, purely subjective virtual reality construct, that somehow magically 8 billion or so people can all individually experience with amazing uniformity.

Nooooo

The correct number of people who are magically locked into individual experiences with amazing uniformity is

8 billion minus 1 individual

Unfortunately the 1 individual

in coming out of this astounding magical uniformity

also lost the magical ability to express what

the alternative to the astounding magical uniformity consists of

What takes the place of

astounding magical uniformity

is now the greatest loss to science

since it was discovered that buttered toast

when it falls to the floor has a greater chance

of landing buttered side down

I don't think you deserve to know. So far no one has demonstrated a capacity to understand the question posed. Some of the responsibility for this is mine due to being unable to articulate in a way that avoids soliciting all these conditioned responses.

Until there is agreement that there is actually a problem that has to be addressed then it is pretty futile suggesting a solution would you agree?
So far no one has agreed that a problem exists....
There is no cognition without ignorance, or the ability to discern what is important to survival and what is not, just as there is no vision without a lack of it, or the ability to discern what is a lack of it. Even a reptilian brain can do this.

The human visual system evolved to process up to five moving images in the visual field at once. That's about the limit for how many predators trying to kill and eat you you might be successful at evading or killing before they get to you, if you are as quick on your feet as you are processing what you see, hear, smell, and touch. It's also how many bilateral / vital extremities you have to protect, but this is Captain Obvious fodder, just like human females in common with other mammals have twice as many nipples as the average number of a litter. Those things can get sore from nursing. Wouldn't want to loose offspring because of that.

It's about the same limit you also have when hunting game. So your vision and cognition are optimized for that level of processing.

But unlike reptiles, we have the mammalian neocortex ability to model the behavior of those we love, as well as those we hunt, or hunt us, even the tools we make and the techniques we develop to make them. This is a quirk in evolution that has given our species and our societies total dominance of this planet. Now when we all have to conform to the way our respective societies think, like a hive of insects, that cognitive advantage will be completely removed by no one but ourselves to blame. The next evolutionary step is not what you think it should be, because there would be no real survival advantage to more cognitively intelligent individuals in this world.

It's very sad, isn't it? Why is that? Don't you all want to be part of a hive mind? All of those terrorists are already there. A hive mind has no problems sacrificing individuals to support their cause. They already had indoctrination to that effect. They were just waiting for something like the Internet to enable them to coordinate their actions. The individuals who sacrifice themselves for the good of the hive need only be armed with a stinger. They have no need of superior individual cognition.

No one can win this. If it is what nature wants, our eventual demise will happen this way. It actually is a battle of social networking, as disgusting as the idea might be.

Warring tribes of humans never fell off the evolutionary tree. The tribes just evolved to cooperate and be more lethal to other tribes. Disinformation gets weaponized as well. If there is an effective countermeasure to that, it won't be from the likes of Donald Trump.

Diversity is important if evolution is going to continue. Hitting a cognitive cull-de-sac like a hive mind does will have survival consequences.

how do you know it is 6 foot.... does the 2 dimensional info on your retina somehow tell you that?

NO

The stereoscopic view and familiarity of the object gives the estimate of distance and size

I recall reading about a tribe who lived in a very dense forest environment

When taken into a wide-open landscape asked the host

why are your cows so small?

Since birth their vision had been limited distance wise

Normal cows at a distance were seen small perspective wise

but in the visual system of the forest dwellers being unfamiliar with distance treated the cows as being small and close

Being lazy I will leave you all to search the net to check its veracity

and the vacant space of approx. 6 foot between you and your mirror is filled in with what color? (visually)

Vacant spaces are not filled with color at all.

We have no direct perception of 3-D space. We see a 2-D image of light being reflected off objects (or emitted from light sources) and entering our eye, to impact at certain angles on our retina. None of this is theory; it is simply optical geometry.

It is our brains that interpret the 3-D rendition of this 2-D image.

It is theoretically possible to fool the brain into thinking it is seeing a 3-D space by placing a carefully edited 2-D image in its way. If we are denied the advantage of our natural stereo vision, and the picture is carefully recreated in sufficient detail, we will mistake it for the real thing.

The question does not make sense

EXCEPT / BUT

It APPEARS you are under the impression that you can see light which does not enter the eye and impact on the retina

You do KNOW light is part of the electromagnetic radiation spectrum and is invisible?

Please tell me you do KNOW light is invisible until it interacts with the retina

Please please please say you KNOW that BASIC bit of knowledge

:)
 
It looks like QQ has made a good case here (because of the length of the interest of the discussion) for starting a forum devoted to discussing philosophy of science.

Anyone second the motion?
 
Holy crap, this is such a stupid thread. Do you see colors in the air space of a room? Are you crazy or on acid?
...just discussing at the level required
of course the space (6ft) between the observer and the mirror ( in this case) has no color yet we observe this vacant space regardless. How?

can't you tell the difference between a 2 dimensional photo imagined as 3 dimensions and what you experience in real time with out a photo being used?
One of the biggest mistakes science makes is to consider the visual brain as some sort of mechanical light interpreting camera. IMO

We do not observe vacant space directly. We only ASSUME it is vacant because light can pass easily through it, and thus if we can see the far side of the room we ASSUME that there is nothing there (or more accurately, the stuff that is there - like air, glass or water - is transparent.)

Only if you move your head, refocus your eyes, employ parallax or otherwise bring additional perception into play. Your visual-capture system alone (i.e. your retina) can't tell.

are you saying that you can't tell the difference to playing a 3 d video game (even on a 4k screen) and turning the game off and taking a walk outside?

I'm in the middle of playing one right now... Horizon Zero Dawn... amazing game... 3 dimensional on a 4 k screen.. stunning graphics...PS4 console.
It takes very little effort to imagine the game from 2 d to 3 d.
