P, maybe too obvious for words--and too tenuous for connection

[Mark Kohut]

In IV, we have in that fine ending the clear statement
of one theme: the vanishing time when people helped each other
for free, without wanting something for it. That echo of it
in the cars jostling in the fog.

In AtD we have the time and person of Nikola Tesla who wanted
free electic power for everyone. Ridiculed and defeated by 
Scarsdale Vibe.
