We create insights and communication by voices

If you manage to block out all sound, you will have no trouble looking around at the warp and woof of the world, but you will feel an outsider, detached from the goings on. Sound puts us in the picture, or makes the picture more than an image. As the Inuit asks the visitor coming in out of the cold. Speak so that I may see you. Add a voice, even a whisper, so that the other is really there.
