When a remnant rebuilds the civilization it most certainly is the civilization. Toynbee never understood society as revelation. As a result he could not comprehend America and neither can you.
Toynbee most certainly did understand civilization! To say he didn’t is rather ignorant.
As for America, which one? The status quo now, 20 years ago, or 200 years ago? They are not the same thing. We are fracturing apart in our habits, ethics, and morals.
