If thought is something we share, then so is reason—what makes us reasoning beings. If so, then the reason that tells us what to do and what not to do is also shared. And if so, we share a common law. And thus, are fellow citizens. And fellow citizens of something. And in that case, our state must be the world. What other entity could all of humanity belong to? And from it—from this state that we share—come thought and reason and law.

~ Marcus Aurelius
