“To begin, I am a citizen of the world. The Earth is my country, and humanity is my nation. This is my motto: What everyone has longed for and will be achieved when all of the people shall also celebrate this prize that every Yemeni, and every Arab, and every human being and every woman has also won beside me.”

Robert Green Ingersoll: "...my religion is simply this: <i>First</i>. Give to every other human being every right that you claim for yourself. <i>Second</i>..." in "The Limitations of Toleration" (The Works of Robert G. Ingersoll, vol. 7, pp. 217-260, quotation on p. 258).

We believe that everyone has the right to be unequal but to us every human being is equally important.

As for “Time heals all wounds” and “Whenever God closes a door, He opens a window”—they, too, make me gloat unconscionably.
