It is generally assumed that blindness experiences a complete darkness. But my personal searche is quite remote from this hypothesis. The logical assumption to be made in a situation where the light stays in the midst of a person will be entirely in the dark. If you go under the duvet, you will not see anything. If you close your eyes, everything will turn back. Then the blind people see totally darkness? Sounds logical, does not it? Not. Although my eyes and my brain are disconnected, the world is not as if it has turned into politics. Look at the video to see what the blind people see in real.
