here to here, about Poul Anderson's Genesis, a late single volume future history covering geological epochs. This December, I have become entirely focused on the first three installments of Anderson's first future history series, the Psychotechnic History.
In this early period of the Psychotechnic History, Secret Servicemen work for the UN whereas, in a transitional period of Genesis (see here), a gifted woman works alone liaising between humanity and the planet-controlling Artificial Intelligence. Ideas of the future change as we move into it.
"A Chronology Of The Psychotechnic Series" on pp. 283-284 of Poul Anderson, Starship (New York, 1982) is:
"Prepared by Sandra Miesel, based in part on the chronology published by Poul Anderson in Startling Stories, Winter, 1955." (p. 284)
So we do not know how much of the 1982 Chronology is by Anderson and how much by Miesel - unless someone has a copy of that Startling Stories? The 1982 Chronology begins:
1958 World War III
1965 First Conference of Rio makes U.N. world government
1975 Psychotechnic Institute established Expeditions to Mars and Venus, then colonization
2009 "The Sensitive Man"
It should read:
1958 World War III, followed by Years of Hunger
1965 First Conference of Rio makes U.N. an instrument of multilateral negotiation
Years of Madness
1975 as above plus Pilgrims emigrate to Mars
the Socialist Depression and other economic breakdowns
2004 as above
2009 as above
At the time of "Un-Man":
"'The U.N. is in the process of becoming a federal world government.'" (p. 71)
