Science Fiction For the science fiction portion of this article, I choose to use Isaac Asimov's definition. Modern science fiction is the only form of literature that consistently considers the nature of the changes we face. , possible consequences and possible solutions. That branch of literature concerned with the impact of scientific advantage on human beings. This definition reflects both the experiences I've had reading the genre and the likely themes of most other science fiction works. This definition is very useful because it doesn't disadvantage itself by putting the changes we face into one category. It was deliberately left open. Many people would say that any science fiction must test humanity or face a threat. This is simply not true. As long as a book addresses the nature of the changes we may face, whether they be a threat, a test, an ethical dilemma, or the opening of new possibilities and horizons, it can be considered worthy of the “science fiction” label. Scientific payoff doesn't have to be a negative story about disaster, it can represent the joy of exploration or the thrill of discovery. True science fiction makes this new something have consequences that require a change in modern thinking. If anything, science fiction is a means to get people to think about problems we may face in the future. For better or worse, they will change the way the world works. The Time Machine HG Wells' Time Machine fits Isaac Asimov's definition of science fiction well. As the change we face, Wells chose the long-term effects of social Darwinism and evolution. The time traveler traveled hundreds of thousands of years into the future and discovered the... center of the card... in two categories: top and bottom. Highly contained world with world building, fantasy situations and low level characters in our world. When I thought about it, I couldn't name any work with a secondary world that wasn't considered fantasy in some sense. Nor could I do the same for novels featuring creatures from our world. Fantasy can be so much more than fairies frolicking in the woods (excluding Phantastes of course), and this definition made it easier to accept that fact. The only minor problem I had with the Boyer-Zahorski definition was the term “low” fantasy. It made me feel like stories based in the real world were somehow inferior to ones set in some grand new land. These distinctions are likely only about the level of fantastic elements in the story, where low is much less fantastic than high, rather than a sign of quality or effort in story writing..
