"normal"

想起很久以前聽過的一場演講，
裡頭提到一個概念：「不知道比知道還恐怖。」

當我們下意識地排除/排斥掉跟我們不一樣的人事物時，
是不是也因此身在色彩中但看不到真實？

Let me give you an example. I came across this story about the Ancient Greek writer, Homer. Now, Homer mentions very few colors in his writing. And even when he does, he seems to get them quite a bit wrong. For example, the sea is described as wine red, people's faces are sometimes green and sheep are purple. But it's not just Homer. If you look at all of the ancient literature -- Ancient Chinese, Icelandic, Greek, Indian and even the original Hebrew Bible -- they all mention very few colors. And the most popular theory for why that might be the case is that cultures begin to recognize a color only once they have the ability to make that color. So basically, if you can make a color, only then can you see it. A color like red, which was fairly easy for many cultures to make -- they began to see that color fairly early on. But a color like blue, which was much harder to make -- many cultures didn't begin to learn how to make that color until much later. They didn't begin to see it until much later as well. So until then, even though a color might be all around them, they simply did not have the ability to see it. It was invisible. It was not a part of their normal.
