Reading is a technology for perspective-taking. When someone else’s thoughts are in your head, you are observing the world from that person’s vantage point. Not only are you taking in sights and sounds that you could not experience firsthand, but you have stepped inside that person’s mind and are temporarily sharing his or her attitudes and reactions. As we shall see, “empathy” in the sense of adopting someone’s viewpoint is not the same as “empathy” in the sense of feeling compassion toward the person, but the first can lead to the second by a natural route. Stepping into someone else’s vantage point reminds you that the other fellow has a first-person, present-tense, ongoing stream of consciousness that is very much like your own but not the same as your own.
