Qualia are the subjective or qualitative properties of experiences. What it feels like, experientially, to see a red rose is different from what it feels like to see a yellow rose. Likewise for hearing a musical note played by a piano and hearing the same musical note played by a tuba. The qualia of these experiences are what give each of them its characteristic "feel" and also what distinguish them from one another.
“非亲身经验而不可知”。
意思是说,没有亲身经验过“红色”视觉经验的人是没有办法了解什么叫做“红色”的感觉。例如,一个出生后就住在只有黑色和白色两种颜色的实验室中而没见过630 nm波长光的人,永远无法体会“红色”到底是什么。直到他有一天走出实验室,亲眼见到630 nm波长光后,他才能体会“红色”的感觉。
