Imagine a neuroscientist who has only ever seen black and white things, but she is an expert in color vision and knows everything about its physics and biology. If, one day, she sees color, does she learn anything new? Is there anything about perceiving color that wasnโ€™t captured in her knowledge? Eleanor Nelsen explains what this thought experiment can teach us about experience.

Kinda reminds me of how I studied grief and loss from both a psychological and physical perspective but didnโ€™t truly understand it until I lost my dad nothing could ever prepare you until you actually feel it for yourself, nothing will ever top personal experience

Isnโ€™t it funny how Jackson probably spent a lifetime to come to conclusions and compare them to form the final question, while we are presented into the topic through a 3 min video.. Internet itself itโ€™s such a privilege, big thanks to Ted education

Reminds me of the quote โ€œExperience is knowledge. Everything else is just informationโ€

I love hearing that he reversed his own position on the thought. According to Kierkegaard, arriving at a paradoxical thought, to ones original position, is the highest point one can attain in philosophizing.

I think a lot of this actually comes down to the weaknesses of language, both scientific and traditional. Nothing can be perfectly described. Hearing about an experience is very different from experiencing it

Just because you know what something is, it doesnโ€™t mean you know how it feels.

Mary did not know what color looked like because that cannot be explained in words. Imagine if she had never felt pain. It would definitely be a new learning experience. She did not know, then she did. She learned.

Mary's room is simmalair to traveling. You can read and maybe know all about it. But experience it, is a whole other thing.

On seeing colour, Mary's retinal cones would be stimulated for the first time, producing changes in her physiology.

why does this give me a feeling that I'll experience something completely new when I die

This is something I've thought about with my schizophrenia. When I'm talking to doctors about it that have studied it for a long time theres still a huge barrier. No matter how much I've been talking about my experiences and feelings, there has never been a satisfying outlet for me to communicate them. And even now that I'm a lot better I can still feel that in my chest that I've been alone in my experience.

If Mary was shown a red and a blue Apple at the same time and she had never seen color before, could she say which color was which? If so then she learned nothing new because she knows enough to tell them apart. If she can not determine which color is which then her seeing color for the first time mean she is learning something

Before I went on vacation to Mexico, I read about this cave of water I would be going to on a trip outside the resort. It sounded so amazing so that's why I bought a ticket to go. When I read about it, it talked about how clear and blue and the water was and how it was life changing. Reading about it was absolutely nothing like experiencing it. It was a totally different concept.

Mary's knowledge of color without having experienced it is abstract, like learning a language that nobody else speaks, understands, or writes in.
