I'm curious what people think of this question: Orwell's 1984, for example, showed readers very clearly what the consequences of living in a surveillance-state are. We all use the term "Big Brother" from the novel when we talk about unwanted surveillance of our daily lives. And yet - despite 1984 being available for decades now - there are many people, particularly in the U.S., who believe that around-the-clock govt surveillance is necessary for personal safety. So as brilliant as Orwell's "1984" is, many people - particularly political conservatives in the U.S. - seem not to have learned any important lessons from it at all. So back to my question: Can a GREAT book really change the world, and for the BETTER? Or is it pure megalomania/unrealistic thinking to expect a book - however great or brilliant - to change the world?
