"America is the only nation in the world that is founded on a creed."

America is the only nation in the world that is founded on a creed. That creed is set forth with dogmatic and even theological lucidity in the Declaration of Independence; perhaps the only piece of practical politics that is also theoretical politics and also great literature. It enunciates that all men are equal in their claim to justice, that governments exist to give them that justice, and that their authority is for that reason just. It certainly does condemn anarchism, and it does also by inference condemn atheism, since it clearly names the Creator as the ultimate authority from whom these equal rights are derived. Nobody expects a modern political system to proceed logically in the application of such dogmas, and in the matter of God and Government it is naturally God whose claim is taken more lightly. The point is that there is a creed, if not about divine, at least about human things.

The Declaration of Independence dogmatically bases all rights on the fact that God created all men equal; and it is right; for if they were not created equal, they were certainly evolved unequal.

There is no basis for democracy except in a dogma about the divine origin of man. That is a perfectly simple fact which the modern world will find out more and more to be a fact. Every other basis is a sort of sentimental confusion, full of merely verbal echoes of the older creeds. Those verbal associations are always vain for the vital purpose of constraining the tyrant. An idealist may say to a capitalist, 'Don't you sometimes feel in the rich twilight, when the lights twinkle from the distant hamlet in the hills, that all humanity is a holy family?' But it is equally possible for the capitalist to reply with brevity and decision, 'No, I don't,' and there is no more disputing about it further than about the beauty of a fading cloud. And the modern world of moods is a world of clouds, even if some of them are thunderclouds.
