Our goal is to identify science fiction books that are remembered over time. We call them the Classics of Science Fiction, even though the term classics is a loaded word for many, and defined in widely different ways. The term science fiction is also controversial, and has never been adequately defined in a precise manner. Working on this project is leading us towards a deeper understanding of both terms. We limit the scope of this project to science fiction because we believe science fiction is a singular concept, even though it can’t be easily defined. Throughout the centuries writers have speculated about the future, distant worlds, alternate histories, time travel, unexplored territories, artificial life, robots, intelligent machines, nonhuman intelligent beings, and other concepts beyond the mundane that could be a part of our reality if we knew more.
