French pilot and author Antoine de St. Exupery publishes The Little Prince, the story of a pilot who crashes and meets a little boy from outer space.

Quotes from The Little Prince:
Voici mon secret. Il est très simple: on ne voit bien qu’avec le cœur. L’essentiel est invisible pour les yeux.
“Here is my secret. It is very simple: It is only with the heart that one can see rightly; what is essential is invisible to the eye.”

Les hommes ont oublié cette vérité, dit le renard. Mais tu ne dois pas l’oublier. Tu deviens responsable pour toujours de ce que tu as apprivoisé.
“Men have forgotten this truth,” said the fox. “But you must not forget it. You become responsible, forever, for what you have tamed.”

“You risk tears if you let yourself be tamed.”

Also in 1943, Oxford scholar C. S. Lewis makes a series of radio broadcasts that will be adapted as a book, Mere Christianity.

Quotes from Mere Christianity:
“God made us: invented us as a man invents an engine. A car is made to run on petrol, and it would not run properly on anything else. Now God designed the human machine to run on Himself.”

“If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world.”
