Notable quotes

“Can you sniff/sense/feel/grok the very thing you covet‥and secretly fear?”
— David Brin, in Heaven's Reach (1998), p. 410
“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 (because of our Earthling assumptions) as color means to a blind man.”
— Robert A. Heinlein, Stranger in a Strange Land (1961)
“There was so much to grok, so little to grok from.”
— Robert A. Heinlein, in Stranger in a Strange Land (1961), Valentine Michael Smith, in "His Preposterous Heritage"
