There are many amazing statements in this book, and if I were more organized, I would've marked them. But here's one that I just came across:
A society becomes totalitarian when its structure becomes flagrantly artificial: that is, when its ruling class has lost its function but succeeds in clinging to power by force or fraud. Such a society, no matter how long it persists, can never afford to become either tolerant or intellectually stable. It can never permit either the truthful recording of facts, or the emotional sincerity, that literary creation demands.
He also predicted the Cold War. Incredibly smart guy.
