“Intellectual life is international. Only a period of discouragement, an age that has given up on itself, that wants to preserve, that has been driven onto the defensive, can be intellectually nationalist. Such a period is essentially conservative. A person who has progress in his heart is international.”

iron is iron till it is rust.
There never was a war that was
not inward; I must

causes war, but I would not believe it.”
