Completion

Several times on the blog I have summarized major themes from a succession of prominent sf writers and then have felt a sense of completion, whether or not blog readers have also felt it. To demonstrate what I mean, I will do it again:

Mary Shelley wrote the first modern science fiction novel, Frankenstein;

Wells wrote a history of the world, a fictional history of the immediate future, an account of time travel to the remote future and an alternative history novel;

Stapledon wrote a fictional history of the entire human (Terrestrial, Venerian and Neptunian) future, then a Neptunian time traveller's perspective on past Terrestrial history, then a history of the cosmos;

Lewis argued against the possibility of time travel and wrote a fragment set on an alternative Earth and a Christian alternative to Wells' and Stapledon's anthropocentric futures;

Heinlein pioneered a different future history model, not a fictional text book but a series of stories and novels set in successive periods, and also developed one time travel paradox;

Asimov wrote a long future history series projecting past historical processes into a future period but also speculating about Artificial Intelligence and "the Frankenstein Complex";

Blish wrote a Heinleinian future history and a trilogy including two post-Lewis volumes;

Anderson wrote historical fiction, alternative history fiction and eight future histories covering Artificial Intelligence and the Frankenstein issue, historical processes repeated in the future, a synthesis of the Wellsian and Heinleinian models and a longer Heinleinian series including two episodes addressing theological issues and also developed every aspect of time travel;

Turtledove and Stirling have specialized in alternative history fiction, developing it further than either Wells or Anderson.

And that still gives me a sense of completion.
