Perceptions

So I was writing a paper tonight about Nietzsche and the way that words are perceived and understood in the world. I use an example from my childhood. It's a little weird to understand but can raise a lot of interesting questions and points so I thought I'd share an excerpt from my paper with you. Let me know what you think and if it made sense. Here goes:

As I was trying to understand this concept it reminded me of some ideas I had when I was probably fourteen years old. I was very interested in the way in which people see things- their sense of vision and how that is interpreted and expressed to each other. I had recently done a career research paper on ophthalmologists and read how they examined the eyes and performed eye surgeries. In my research I learned how one actually is able to see things, the image being translated in the eye and then sent as a visual electric stimulus to the brain. At one point I began to wonder if everyone saw the world exactly as I did. For example, say I am looking at the sky and I see the color “blue” as signified by its hue, saturation, and brightness, and a friend of mine is also looking at the sky and seeing what he calls “blue.” I wondered if I were to switch consciousness with him in some way so that I could see out his eyes yet translate the color with my own brain would I still identify that color as “blue” or would it suddenly appear to have a different hue, saturation, and brightness so that I would call it turquoise or even green. As a fourteen year old I came to terms with the fact that I would probably never know if my theory was true, but I never forgot how intriguing it was to try to understand another’s perceptions of reality. I think this is what Nietzsche is trying to express.
