"There are some who say that sitting at home reading is the equivalent of travel, because the experiences described in the book are more or less the same as the experiences one might have on a voyages, and there are those who say that there is no substitute for venturing out into the world. My own opinion is that it is best to travel extensively but to read the entire time, hardly glancing up to look out of the window of the airplane, train, or hired camel."
