I certainly don’t like the idea of missionaries. In fact, the whole business fills me with fear and alarm. I don’t believe in God, or at least not in the one we’ve invented for ourselves in England to fulfill our peculiarly English needs, and certainly not in the ones they’ve invented in America, who supply their servants with toupees, television stations, and, most important, toll-free telephone numbers. I wish that people who did believe in such things would keep them to themselves and not export them to the developing world.
