The original name of the InSights was "In Seeing the Eye Disappears." These words are written on some of the physical panels.
The purpose of this riddle is to draw attention to the mystery of perception:
in seeing the eye disappears
in hearing the ear disappears
in touch the skin disappears
and so on.
If the senses were not ""transparent,"" we would not perceive the world. We perceive the world precisely because the senses are "invisible."
