My all-time favorite Sartre-ism has been coming to mind a lot more lately.

In the novella Nausea, Sartre's character goes off on a long tangent about what would happen if the world suddenly changed and all sorts of impossible monstrosities came to life, ending with:

"I'll shout: "What's the matter with your science? What have you done with your humanism? Where is your dignity?" I will not be afraid— or at least no more than now. Will it not still be existence, variations on existence? All these eyes which will slowly devour a face— they will undoubtedly be too much, but no more so than the first two. Existence is what I am afraid of."

I find the thought rather comforting.

"Perinthia's astronomers are faced with a difficult choice. Either they must admit that all their calculations were wrong ... or else they must reveal that the order of the gods is reflected exactly in the city of monsters." - Italo Calvino
