This is more along the lines of society/economics, but _I'd_ recommend
Jane Jacobs. Maybe not for a core list, but I'd recommend her in
general. _Death and Life of Great American Cities_ is a deep analysis
of how cities work, as complex systems, and is said to have overturned
the urban planning movement. _Cities and the Wealth of Nations_ has
some interest pragmatic libertarian arguments: large nation-states
stifle their own economies and would do better as trading city-states.
Secession as economic reproduction, in addition to economic growth.

Beneath these hills great heroes lie
Of the Red Branch Knights and their ancient foe.
In still of night the immortals fight
But never the battle is won.
