“Watching a movie about the Cuban Missile Crisis shows you a drama. Reading about it shows you a dilemma. The book makes you imagine the color, sound, tone and tension, the logic of the events: it makes your brain do the work. A movie is received passively: you sit back, see, hear. Books demand and reward. When you read them your knowledge base deepens and expands. In time that depth comes to inform your work, sometimes in ways of which you’re not fully conscious.” Peggy Noonan, Wall Street Journal, Oct 1-2, pg A11
