"The Time Machine" by H.G. Wells (published 1895)
The first line in the Epilogue of H.G. Wells' The Time Machine (1895) is as follows: "One cannot choose, but wonder." Other than how apt a reflection of the Time Traveller's story as well as the main narrator's and how humble an acceptance, how gracious a plea this is, it is also a main marker of the kind of science fiction I enjoy: whether or not one is presented with proven fact is not the issue. The issue is rather thinking and moreover, wondering what's become and what is to become of the story itself. This particular classic novella of science fiction begins with a request: that the Time Traveller's companions; the Medical Man, the Editor, the Psychologist, the Very Young Man, the Journalist, the Silent Man, and our narrator listen to the Time Traveller's story - with no interruptions - hear him out as if he were a professional storyteller indeed. The Time Traveller cares not whether they believe him but it is clear that he wants to tell it.
