Response to mickey d.
I actually have 3 irrefutable proofs that light/brightness exist outside of your "mind", and that color is 100% real outside of you (subjective reality is not objective reality). And you can't do nothing about it. (I shouldn't be showing evidence if you had a brain to understand the OBVIOUS fact that light exists independently of you, but since you like to make a fool of yourself, and since there are still people who believe that the earth is flat, I have to show proof, because it seems that we are still living in flintstones era..
First light..
1. How do you explain a new recent discovery that a form of octopus can sense britghness with Its own skin? (without brain or eyes or humans needed) ? [search google]
2. Then you believe that when you close your eyes, your "mind" is also creating the "appearance" that there is brightness outside of you to "trick" you. Wow, nice mind trick.
3. You are utterly finished here.
Take your phone or a camera without adjusting the ambient light to the camera, now take a pic without any person around, reveal the photo in matte paper, If your camera wasn't adjusted to the ambient light you'll see a lot of brigthness (glares, halos or starburstings of light) in the revealed photo, because you didn't adjusted the camera to the ambient, yes, you will see it in the matte paper. Now tell me where is the subjective part here? Where were your brain needed to create brightness in the matte paper? This is direct evidence dude, deal with it, light has nothing to do with "created by your mind," This is a Lie. Hands down.
now colors...
1. As we know (basic physics) brightness is actually all colors mixed (and cannot exist without colors), because light IS color, (basic science), and OBVIOUSLY brightness is proved to exist outside of us (octopus, a closed eye and the camera example), so we conclude that color is real outside of the brain.
2. a blind person from birth can't dream in images, only someone who experienced colors first can dream in images, already proving that subjectivity depends on the objective world. your brain depends on the objective world to create Its own dreams. the brain can't create something out of nothing, If this was the case, someone blind from birth would know how a color looks like.
3. thus proving that color is 100% real outside of the 'mind'. And that people differ from perception because of the 'rods and cones', not because of your 'mind' (basic biology)
.
Deal with it.
