In one way, traveling has narrowed my mind. What I have discovered is something very ordinary and unexciting, which is that humans are the same everywhere and that the degree of variation between members of our species is very slight. This is of course an encouraging finding; it helps arm you against news programs back home that show seething or abject masses of either fanatical or torpid people. In another way it is a depressing finding; the sorts of things that make people quarrel and make them stupid are the same everywhere.
