A time traveler visits the far future;
men traverse interplanetary space;
Martians invade Earth;
there will be wars and revolutions;
an alternative history unfolds on a parallel Earth.
I have just summarized five major sf works by HG Wells - and also by Poul Anderson.
Moving on from Wells:
Stapledon gave us cosmic sf;
Capek gave us robots;
de Camp gave us a time traveler changing history;
Heinlein gave us a future history series, a generation ship, science fictional treatment of immortality, juvenile sf, elaborate circular causality and magic as technology;
Asimov gave us robotics and a predictive science of society;
Anderson developed all of these themes.
The blog has entered territory where we are comparing future histories, including several by Anderson, and assessing collaborative future histories. Thus:
Niven created a future history series that includes a period of wars between men and kzinti;
Pournalle and Stirling wrote stories set in this period;
Anderson wrote sequels to Pournelle's and Stirling's Man-Kzin Wars stories.
We have come a long way from Wells' Martians invading Earth but are clearly in the same literary tradition. We find Anderson seeing far because he stands on the shoulders of:
Wells
Stapledon
Capek
de Camp
Heinlein
Asimov
Niven
Pournelle
Stirling -
- and we have not yet mentioned Mary Shelley, creator of science fiction and of the Frankenstein theme developed further by Capek, Asimov and Anderson.
