“All the sons of Adam are part of one single body
They are of the same essence.
When time afflicts us with pain
In one part of that body
All the other parts feel it too.
If you fail to feel the pain of others
You do not deserve the name of man”

—Saadi Shirazi—

The great Persian poet who was captured and enslaved at Acre by the Crusaders. These (his) words now stand at the entrance of the headquarters of the United Nations.
