Quotation

"...The Martians seem to know instinctively what we learned painfully from modern physics, that observer interacts with observed through the process of observation. 'Grok' means to understand so thoroughly that the observer becomes a part of the observed-- to merge, blend, intermarry, lose identity in group experience. It means almost everything that we mean by religion, philosophy, and science-- and it means as little to us as color means to a blind man."
