C. S. Lewis, “The Seeing Eye” in Christian Reflections (Eerdmans, 1967), pp. 168-167:
Avoid silence, avoid solitude, avoid any train of thought that leads off the beaten track. Concentrate on money, sex, status, health and (above all) on your own grievances. Keep the radio on. Live in a crowd. Use plenty of sedation. If you must read books, select them very carefully. But you’d be safer to stick to the papers. You’ll find the advertisements helpful; especially those with a sexy or a snobbish appeal.
