There is one short rule that should regulate human relationships. All that you see, both divine and human, is one. We are parts of the same great body. Nature created us from the same source and to the same end. She imbued us with mutual affection and sociability, she taught us to be fair and just, to suffer injury rather than to inflict it. She bid us extend our hands to all in need of help. Let that well-known line be in our heart and on our lips: "Homo sum, humani nihil a me alienum puto"."
