The MacGuffin in Glory Road is the Egg of the Phoenix, a cybernetic record of the experiences of two hundred and three “emperors” and “empresses,” most of whom “ruled” all the known universes — and serves as an excuse for Heinlein to share his thoughts on politics:
For the one thing that stood out as this empirical way of running an empire grew up was that the answer to most problems was: Don’t do anything. Always King Log, never King Stork — “Live and let live.” “Let well enough alone.” “Time is the best physician.” “Let sleeping dogs lie.” “Leave them alone and they’ll come home, wagging their tails behind them.” Even positive edicts of the Imperium were usually negative in form: Thou Shalt Not Blow Up Thy Neighbors’ Planet. (Blow up your own if you wish.) Hands off the guardians of the Gates. Don’t demand justice, you too will be judged.
Above all, don’t put serious problems to a popular vote.
Our hero meets a comparative culturologist from one of the many other inhabited planets:
But tell me: How were things when you left? Especially, how is the United States getting along with its Noble Experiment?”
“ ‘Noble Experiment’?” I had to think; Prohibition was gone before I was born. “Oh, that was repealed.”
“Really? I must go back for a field trip. What have you now? A king? I could see that your country was headed that way but I did not expect it so soon.”
“Oh, no,” I said. “I was talking about Prohibition.”
“Oh, that. Symptomatic but not basic. I was speaking of the amusing notion of chatter rule. ‘Democracy.’ A curious delusion — as if adding zeros could produce a sum. But it was tried in your tribal land on a mammoth scale. Before you were born, no doubt. I thought you meant that even the corpse had been swept away.” He smiled. “Then they still have elections and all that?”
One of our hero’s companions later adds:
“Except that he sees only the surface. Democracy can’t work. Mathematicians, peasants, and animals, that’s all there is — so democracy, a theory based on the assumption that mathematicians and peasants are equal, can never work. Wisdom is not additive; its maximum is that of the wisest man in a given group.
“But a democratic form of government is okay, as long as it doesn’t work. Any social organization does well enough if it isn’t rigid. The framework doesn’t matter as long as there is enough looseness to permit that one man in a multitude to display his genius. Most so-called social scientists seem to think that organization is everything. It is almost nothing — except when it is a straitjacket. It is the incidence of heroes that counts, not the pattern of zeros.”
He added, “Your country has a system free enough to let its heroes work at their trade. It should last a long time — unless its looseness is destroyed from inside.”

“I could never be a democrat at heart. To claim to ‘respect’ and even to ‘love’ the great mass with their yaps at one end and smelly feet at the other requires the fatuous, uncritical, saccharine, blind, sentimental slobbishness found in some nursery supervisors, most spaniel dogs, and all missionaries. It isn’t a political system, it’s a disease. But be of good cheer; your American politicians are immune to this disease…and your customs allow the non-zero elbow room.
