The Problem of Qualia

The hard problem is explaining how on earth that experience could have been generated in me from a purely physical brain. And this is sometimes called the problem of qualia, isn't it? This notion that there is a qualitative aspect to our experience. We can tell quite a detailed story about the light rays hitting your eye being focused by the lens in your eye onto your retina. But how in the course of that does the experience itself arise? The color that you experience is something private and we don't know whether other people see the same colors in the same way.
