What a great point. Thank you so much.
Frankly the lines, "presently word would come that a tribe had been wiped off its ice field, or the lights had gone out in Rome," has as much power as any in literature. It perfectly captures the inevitability of reality--of a day of reckoning for human folly--whether to the simple or complex varieties of human species.
The writing is clearly on the wall. We will either wake up America now, or stand impotent as the lights go out.
