“Quiet Spaces
We had gone far enough together to listen easily in the quiet spaces.”

Is Google Making us Stupid in The Atlantic, July 2008.
Context: The kind of deep reading that a sequence of printed pages promotes is valuable not just for the knowledge we acquire from the author's words but for the intellectual vibrations those words set off within our own minds. In the quiet spaces opened up by the sustained, undistracted reading of a book, or by any other act of contemplation, for that matter, we make our own associations, draw our own inferences and analogies, foster our own ideas…. If we lose those quiet spaces, or fill them up with 'content,' we will sacrifice something important not only in our selves but in our culture.
