… if you saw a Guugu Yimithirr speaker pointing at himself, you would naturally assume he meant to draw attention to himself. In fact, he is pointing at a cardinal direction that happens to be behind his back. While we are always at the center of the world, a Guugu Yimithirr speaker points through himself… - Guy Deutscher, The New York Times, 2010 @RABBIGREENBERG

“When a language dies, a way of understanding the world dies with it, a way of looking at the world.” - George Steiner @RABBIGREENBERG
