here. I wanted to show how a succession of writers not only follow their predecessors but also make significant new contributions to earlier themes. Mary Shelley and Isaac Asimov have been added to the list.
The themes that emerge are:
artificial life and intelligence
secularism versus supernaturalism
The vastness of Poul Anderson's contributions is obvious.
Significant indeed and some themes have to be left out to make the summary manageable. From Shelley to Stirling, 1818 to 2017 - and who is next?
