The story happened in the late 1800's. Most of the content of this book is flashback. Normally flashback returns to history. But in Time Machine, this is a flashback that you can go back to last week. This is also a distant future. The complexity of this story is that it is a story in the story. An adventure that has happened but has not yet happened. "Time Machine" is complicated because it takes time. I found three symbols, Sphinx, statue of Eloy, and Morlock. Sphinx stands for obstacles between Eloi and Morlocks. Eloy represents humanity. They love me so much and I like to come back. But Morlocks is the opposite. They are greedy, cold, cruel and frank. The whole book is about men's tournament. The tourist, Weena, saved the Eroy from the water. She was used by HG Wells to show how they look. Because she is very intimate with a time traveler

Timely trip is a great human desire. The Delphi gods, the popular futuristic movie time machine, the mysterious crystal ball, and even the modern prophecy, symbolized the predictive future attitudes and attitudes. Perhaps for this reason, we still think the time is linear: past, present, future - they are all bound by a straight timeline. The problem is that the future is open, it is the product of our idea, equally important is past and present. They are all artificial. What is the value of how to deal with it when the "future" is still not in time? I would like to consider using the future as a place, more accurately speaking of using the future as an alternative. Uncertainty and complexity are a negative factor in our time. But the problem is not based on these basic principles but from how we control the future. You should not treat the future as time, but as an alternative to the future you should map it to another place.
