Stupidity can win for a moment, but it can never really succeed because the nature of humans is to seek freedom. Rulers can delay that freedom, but they cannot stop it.
It recognizes no morality but a sham morality meant for deceit, no honor even among thieves and of a thievish sort, no force but physical force, no intellectual power but cunning, no disgrace but failure, no crime but stupidity.
They're talking about things of which they don't have the slightest understanding, anyway. It's only because of their stupidity that they're able to be so sure of themselves.
