Isn’t that a great quote? It is from Simone de Beauvoir’s “The Mandarins”–a novel I do not suggest you read. It is a very wordy 600+page book, mostly about Stalinist politics in post-WW2 France.
No one has much fun in this novel. Much as I admire de Beauvoir, I would much rather read Colette. But now you don’t even have to consider reading this novel, as I have pulled the best quotation from it for you!
