“Readers didn’t just become more efficient. They also became more attentive. To read a long book silently required an ability to concentrate intently over a long period of time, to ‘lose oneself’ in the pages of a book, as we now say. Developing such mental discipline was not easy. The natural state of the human brain, like that of the brains of most of our relatives in the animal kingdom, is one of distractedness. Our predisposition is to shift our gaze, and hence our attention, from one object to another, to be aware of as much of what’s going on around us as possible….For most of history, the normal path of human thought was anything but linear.
To read a book was to practice an unnatural process of thought, one that demanded sustained unbroken attention to a single, static object. It required readers to place themselves at what T.S. Elio, in Four Quartets, would call ‘the still point of the turning world.’ They had to train their brains to ignore everything else going on around them, to resist the urge to let their focus skip from one sensory cue to another. They had to forge or strengthen the neural links needed to counter their instinctive distractedness, applying greater ‘top-down control’ over their attention…What was so remarkable about book reading was that the deep concentration was combined with highly active and efficient deciphering of text and interpretation of meaning. The reading of a sequence of printed pages was valuable not just for the knowledge readers acquired from the author’s words but for the way those words set off intellectual vibrations within their own minds. In the quiet spaces opened up by the prolonged, undistracted reading of a book, people made their own associations, drew their own inferences and analogies, fostered their own ideas. They thought deeply as they read deeply.
…Reading a book was a meditative act, but it didn’t involve a clearing of the mind. It involved a filling, or a replenishing, of the mind. Readers disengaged their attention from the outward flow of passing stimuli in order to engage it more deeply with an inward flow of words, ideas, and emotions. That was—and is—the essence of the unique mental process of deep reading.”
