Quote by Damon Knight
Science fiction... means what we point to when we say it.
This quote suggests that the term "science fiction" is defined subjectively by individuals. It implies that there is no universal definition for science fiction and that it is merely a label that we assign to various works based on our own interpretations and perceptions. Each person may have their own criteria for identifying what they consider to be science fiction, leading to a diverse range of opinions and understandings of the genre.
Memory is the great deceiver. Perhaps there are some individuals whose memories act like tape recordings, daily records of their lives complete in every detail, but I am not one of them. My memory is a patchwork of occurrences, of discontinuous events roughly sewn together: The parts I remember, I remember precisely, whilst other sections seemed to have vanished completely.
