“You are not the center of the world.”
Most of the people of the world are convinced that their religion and their nation were crucial to the establishment of the world as we know it. British, French, German, American, Russian, and others are sure that people would live in barbarous and immoral ignorance if it had not been for their countries special achievements throughout history.
And yet humans, long before any nation had been established or religion founded, had colonized the world, invented farming and agriculture, invented money, and writing. All civilizations were built on the same foundations. Thinking that your nation is special, or your religion is the only true one, shows an ignorance of history with more than a hint of racism.
