This is a lecture video about the inverted experience thought experiment, as well as about the scientific evidence that some percentage of men are, in reality, red-green color inverted. This is part of an introductory level philosophy course.

You have single handedly helped me pass my Philosophy of the Mind module. Thank you so much for your channel!

Regarding the warm / cool part of the talk, because this is a psychological experience, those that see red as green would still say that it was a warm colour, because to them, a fire would look green and feel warm. Also there would be some conditioning involved where people would be saying or teaching that their perceived 'green' was a warm colour. (Imagine an art teacher teaching which colours were warm and cool.)
Also, purple is only a unique colour because of language and there is no way it can be regarded as a pure colour in colour science. There are 4 primary psychological colours, red, green, yellow and blue. All other colours are considered mixtures. And there are only 3 in additive light which are red, green and blue, which roughly correspond to the L, M, S cones in the retina, with all other colours being mixtures.
So I think the purple, yellow/green argument is fallacious.

Everyone could have the same favorite color qualia-wise.

I just discovered your channel. I'm a technician and a bit of a nerd and, while philosophy has always held some fascination for me, it has never really appealed all that much to me. The two presentations by you that I have watched have given the subject new meaning for me. Thank you. Shalom.

This blew my frickin mind wow

Unbelievable! I just stumbled into your channel. I've contemplated this quandary since I was a teenager. I had a color blind friend and we had some really deep conversations over it. I realize that being color blind is not the exact same thing but it was the segway to the inverted qualia idea. I have brought this idea up to so many people and it seemed that I was the only one that ever questioned it. I've absolutely explained my theory almost verbatim using fire engines and tomatoes compared to grass and trees. However, I could never really get anyone to agree with me or to even show much interest so I actually thought that I was the only one that ever explored this possibility, let alone did I know it actually has a name! Inverted qualia. I feel like I just found another human being on what I presumed to be a deserted island. Thank You! By the way, I've just became a subscriber.

You could say the functionalist is describing the function for each individual not every person who ever lived. Had there been 2 identical persons with identical brains in identical situations, there is no reason to think their experiences would be different.

I am an electronics engineer who spent the last seven years of my life as a color scientist. Working with laser based and LCD color proofing systems. The three types of cones are long, medium, and short wavelength photo pigment sensitive areas. Long is what you refer to as red, medium is green, and short is blue. I can get a colormetric match in a normal humans by stimulating both the long (red) and medium (green) cones. The person will perceive yellow. I can do this with a single wavelength of light (yellow) or I can get the same perception by mixing red and green light from an LCD screen.
If I mix blue and red light the person will perceive magenta. There is no single wavelength of light that produce this same perception. Now if the person has the red and green reversed connections it would be able to produce this same perception with a single wave length of light that overlaps blue and green. This is an objective way to detect if these people exist. I am a functionalist. Talk with a color scientist if you want to know more...BTW I am an anomolus trichromat. A person who sees all wave length of light, but sees luminance differences stronger than color differences that "normal" people see. This can be discovered with a series of tests. I found this out when I applied to get a commercial pilots license. I was able to get that license by using the 100 hue Farnsworth test instead of the Ishihara dot test.

It is now the second video of you that I watch and I experience a deja vu. I read William Poundstone's Labyrinths of Reason 30 years ago...

Protanopia and Deuteranopia are types of Anopia.
Greek: An - meaning un, without. Opia - meaning vision
Protanopia. Prot - from proto greek meaning first of a pair. Green looks more red.
Deutranopia. Deuter - from deutero latin meaning second of a pair. Red looks more green.
Protanope - a protanoptic person with protanopia who has the condition of protanomaly.
Deuteranope - a deuteranoptic person with deuteranopia who has the condition of deuteranomaly.
(Optal - visionary, about vision.
Optic - from French short from Greek opticus,
which comes from Greek: opto - visible and ikus - adjective suffix)

The fly in this ointment: color blindness.
My relative is color blind to red hues, I was surprised when I was told this. The first question I had was, how do you know to stop at a red light, their answer was when the top lights bright I Stop.

Great content! Can you do an in depth video on Dworkin's constructive theory next?

Okay I'm looking this up because I found out I'm color blind. But I thought that meant I can't see colors. No, I swear to you my greens are blues, certain yellows and oranges are pink, I thought my parents taught me wrong. One day i changed my shirt to a shirt I thought was pink. I don't like the color. My fiance during game night said he liked it, I said " I'd like it more if it wasn't pink" everyone stopped and stared at me and was like...thats yellow. Then we later went over flash cards and to me I was like no was these cards have to be wrong...

I thought about this very thing when I was growing up because my left eye saw red less saturated or more subdued than my right. I have heterochromia or whatever its called and I wondered if having different eye colors might affect what peoples favorite colors were because of how they perceived colors.

In college, I was diagnosed with red-green color blindness. I did not know. I could identify reds and greens, but one time I was told I got it wrong. I would have kept my functional state had I not been told. Now I have a practical difference. The difference I experience for red and green would not create a different quality experience. I just believe what I was told. I would not even know if it wasn't for the eye diagnosis and the feedback.

Damn these videos are enjoyable

I once had some medication that suppressed my green receptors under strong light conditions. It's not qualia inversion, but it's amazing how quickly you get used to grass being a dull greyish orange!

But the reaction to a fire truck is also learned, so the person with inverted qualia just has an equivalent reaction to what he perceives, as someone with non-inverted qualia to his perception.
It's rather strange to first argue, that the person born with inverted qualia would just build all its associations to match just that, effectively "wire" the input so green associates with gras and red with a fire truck, but then argue, that the functional states are fundamentally different, when they're just equivalent with a rather primitve mapping (exchanging red for green).
Also functionalism doesn't care which lanes of nerves transport a green signal and which ones transport red, or even if it's nerves at all, it's completely sufficient, that someone who learned what gras looks like in his sensory system, inverted or not, remembers that association e.g. when describing something else as "gras green".

I thought of this in 5th grade and explained it to my friends on the playground. Later in college when I studied perception and psychobiology, I learned about cones and rods and the evolution of the eye, which tells us that we process the light spectrum the same way.. yes, there’s color blindness, but that’s different and mostly about how we parse blends or mixes of colors

I remember thinking about the possibility of inverted qualia when I was about 11/12 years old, imagining about people seeing other people thoughts. In the end I assumed it was true and irrelevant and went on with my life, never thinking that I had accidentally bumped into a real philosophical doubt
