We had no idea that sounds existed beyond the range of human hearing until we developed instruments to detect, measure, and create them. Until comparatively recently, those who claimed they could hear what others could not were considered insane or persecuted as witches and sorcerers.

We are still unaware of the capacity of the human brain, an electrochemical organism, in terms of transmission and reception of electromagnetic radiation. With this gap unbridged, it is easy to understand why modern science has not begun to consider the ability of the human mind to penetrate an area where no serious theory has been promulgated. (en) |
