A few years ago, I performed an experiment in a philosophy class I was teaching. My students had failed a midterm test rather badly. I had a hunch that their pervasive use of cell phones and laptops in class was partly responsible. So I asked them what they thought had gone wrong. After a few moments of silence, a young woman put up her hand and said: “We don’t understand what the books say, sir. We don’t understand the words.” I looked around the class and saw guileless heads pensively nodding in agreement.
