Dirac made me think about and rethink James Blish's Haertel Scholium. An omnibus collection of the Scholium would comprise eleven works, a two part prequel/prologue/prelude, Welcome To Mars and "No Jokes On Mars," followed by three trilogies:
The Galactic Cluster Trilogy
"Nor Iron Bars"
"This Earth Of Hours"
The Heart Stars Trilogy
The Star Dwellers
Mission To The Heart Stars
"A Dusk Of Idols"
The Quincunx Trilogy
The Quincunx Of Time
"A Style In Treason"
In "This Earth Of Hours," the Terrestrial Matriarchy must contend with the Central Empire of the galaxy;
in the Heart Stars trilogy, the UN and the star-dwelling Angels must contend with the Heart Stars federation;
in "A Style In Treason," High Earth must contend with the Green Exarchy;
in The Quincunx Of Time, Earth, armed with the Dirac transmitter, builds its own intergalactic civilization;
in a twelfth Haertel Scholium work, A Case Of Conscience, which is Volume III of the After Such Knowledge Trilogy, the UN must cope with the planet Lithia which, in accordance with this novel's place in the ASK Trilogy, is a third historical example of the question whether the quest for secular knowledge is evil.
