Kings and priests are machinations of man, they exist not as external adversaries, blights unto who would otherwise be naturally enlightened, but a salve to our deep, innate need for surety, protection, charms against the fear of the unknown.

If it's true that mankind won't be truly free until the last king is strangled with the entrails of the last priest, mankind won't truly ever be so, because it'll invariably be the last one to die who is the king, and the one before, the priest. We might as well make peace with it.
