"All things are woven together and the common bond is sacred, and scarcely one thing is foreign to another, for they have been arranged together in their places and together make the same ordered Universe. For there is one Universe out of all, one God through all, one substance and one law, one common Reason of all intelligent creatures and one Truth.
Frequently consider the connection of all things in the universe.
We should not say ‘I am an Athenian’ or ‘I am a Roman’ but ‘I am a citizen of the Universe."

(Marcus Aurelius, Meditations)
