[edit] Overarching themes
- See also: Science fiction genre
-
- Science fiction is used to raise awareness of ecological ideas. Lends itself well to dystopian futures. Frank Herbert and Kim Stanley Robinson are known for their serious concern with ecological issues.
- Economics
- "Age of Greater Scarcity", often in connection with ecological or post-apocalyptic themes. In such dystopias, people are poorer and have fewer resources to draw on.
- Post-"Age of Scarcity" (arguments over how to distribute resources are irrelevant since anyone can have anything they reasonably want). Examples include:
- History
- Alternate history
- Historical cycles: history repeating itself (either on long or short scales)
- Scientific prediction of the future (e.g. psychohistory)
- Secret history
- Fantasy fiction
- The future
- Horror fiction
- Language
- Alien languages (e.g. Klingon)
- All humans speaking one language (possibly Esperanto)
- Current human languages evolving/splitting
- The Sapir-Whorf Hypothesis being strongly true (e.g. Babel 17 by Samuel R. Delany or The Languages of Pao by Jack Vance)
- Universal Translators (e.g. Babel fish)
- Military - strategy, weapons, ranks, technologies.
- Parallel worlds or universes.
- There is a space based civilization variant of this theme. This plot device allows writers to write soft science fiction while accounting for the lack of technological advancement and thus similarity to the present day.
- Religious ideas in science fiction
- Sex (including gender roles, polygamy, sexuality and procreation)
- Sociology and sociobiology
- Astrosociology
- return to feudalism
- hive-like eusocial societies
- future caste systems

- Infomorphs - memories, characters and consciences of persons being uploaded to a computer or storage media
- Noosphere - the "sphere of human thought"
- Solipsism - a belief that the universe is entirely the creation of one's own mind
- Mutants

- Clones
- Uplifted animals - using technology to "raise" non-human animals to human evolutionary levels
- Characters
[edit] Body and mind alterations
- Bio-implants
- Body modification, including genetic modification
- Bionics

- Mind interfacing
- Memory removal/editing
- Mind control
- Mind uploading
- Neural implants to directly interface with machinery
- Nanotechnology
- Psi powers and psychic phenomenon
- Resizing (size-changing, miniaturization, magnification, shrinking, and enlargement)
- Shapeshifting
- Telepathy
- Teleportation
[edit] Possible futures
- Alien invasions
