Perception (Warning: This thread probably won't make a bit of sense)

[pkt-zer0]

Maybe every person sees the(for example) sky color differently, but everyone of them have sky color and other things with similar color defined as blue. That also maybe the reason why every person has its own favourite color... And why is it possible for people to view colors same way, if they have different color of eyes? It should be like watching through coloured pieces of glass...

The color of the iris doesn't really affect how you see colors.
It's pretty interesting though, how reality itself seems to be both highly subjective, due to altered perceptions, and still very constant among large masses of people. Collective subconscious? Or is there something else that defines for people in general what reality is and what isn't?
I'm not going to try and answer that.

thats why science gives colors and things like that numerical values, because who is to say what color is blue? It can be proved that the sky's color value is 9.45769 today, but its almost impossible to prove its blue.

If blue has for value 9.45769, and so does the sky, then the sky is blue.

Blue is the name given to a certain range of lightwave lenghts. It that lightwave strikes our retina from the direction of the object we're looking at, then our brain sees that object as being of that colour.

The sky is blue because it's the name given to the colour we perceive from it.

The color of an apple or the taste of chocolate are rather constant because we are all roughly equipped with the same sensors. Yeah, reality is defined by generaly accepted agreements like that killing is bad, the sky is up and size does matter.

I truly don't see anything mind boggling about the perception of things.

Just being one among the many, who are you to decide what is generally accepted and what isn't?

Errr, ok then. Who are you to question what is generally accepted? It's not because you disagree that the "generally" takes the boot.

Besides, I don't decide anything, Pkt, I just state the obvious. Being built roughly the same way, it's only normal that some "matters" be generally accepted. Unless you believe that the sky isn't up...

Anyways, what are you getting at? :\

[Valholy]

Someone has been watching the matrix recently ,seriously I also think like that from time to time

I just question the absolute power of human mind. Thoughts can be so easily altered that they don't seem to be worth much anymore. Messing around a bit with your inner ear could make you feel that the sky isn't up.
So, where is exactly the limit to which humans can be altered? Limbs can be replaced by machines, hearts can be replaced by machines, it's not long until our brains can be replaced with machines as well. What shall remain then?

The sky is above your head, that is a fact. Whether your perception of that is so or not, it changes not that fact. Why is it up? Everyone around you sees it that way. That's why. Had we all different senses and perceptions, we could not be, just like one of every animal placed on the moon (with air and food) wouldn't last long. Do you think we could live if we didn't all agree that killing is wrong? Of course, we don't ALL agree, but since the majority wins, we live.

Never will the brain be emulated perfectly, no machine could ever describe how it feels to see yourself soaring through the universe and visiting entire worlds based only on your imagination. Never. Sure, at one point, we'll most likely have robots that can do stuff for us or with us, but they will never best us, intellect and imagination wise. A machine cannot calculate a rational deduction from a series of philosophical conundrums without having a program that would interact with their knowledge and emotions and stuff. Never.

I always think about stuff like that. Something you might see blue could be red for someone, but since he was told it was blue your red is his blue.

The sky is above your head, that is a fact. Whether your perception of that is so or not, it changes not that fact. Why is it up? Everyone around you sees it that way. That's why.

If you stand on your head all you life, is the sky still up to you? Or is the Gound up...

What is really up anyway... If your on earth the sky is really all around you at all times...

It's on the other side of the earth below your feet, it's to your left and right...

From what I gather about this thread it's about that "certain point of view" question...

Yes reality as I see it anyway, is subjective.

[Evans]

If you stand on your head all you life, is the sky still up to you? Or is the Gound up...

If you're the only person on Earth thinking that, then it doesn't mean it is. To you, maybe, but not to the others.

It's on the other side of the earth below your feet, it's to your left and right...

Well, if you wish to take things out of context...
Space is all around us, the part of it that is above our heads is what we call the sky.

Yes reality as I see it anyway, is subjective.

How can reality be subjective? It's contradictory to it's nature, if not even to it's "purpose".

It a sorta way, reality is subjective, even though it's contradictory to it's nature.
Now, please test this brick wall by running thru it.

See..

oh no, finally it was also hard for you.

[polokitty]

hah polo makes a point and then pricks you

[Norgus]

People's perception of reality is subjective, reality isn't subjective as reality does not percieve.

In terms of the colours argument I decided to google up an image illustrating this nicely

These values are obviously roughly the average of the human light sensory and perception of colours seperated into what wavelength of light each colour roughly belongs.
The perception of ranges of wavelengths undoubtedly changes from person to person and the perception of them in the mind probably also changes somewhat from person to person. But they are sensed and percieved consistenly enough that we can give a general name to each range.

Finaly.

[polobunny]

Yeah, too much words to write, so Norgus did it for you.
