“Man is the religious animal. He is the only religious animal. He is the only animal that has the true religion--several of them. He is the only animal that loves his neighbor as himself and cuts his throat if his theology isn't straight. He has made a graveyard of the globe in trying his honest best to smooth his brother's path to happiness and heaven.” (Mark Twain)

"The world is my country; all of humanity are my brethren; and to do good deeds is my religion." (Thomas Paine)
