André Gide, La symphonie pastorale (Paris: Gallimard, 1925; 1919), pp. 64-65:
ah! que la vie serait belle et notre misère supportable, si nous nous contentions des maux réels sans prêter l’oreille aux fantômes et aux monstres de notre esprit...My translation.
oh! life would be beautiful and our misery bearable if we were content with genuine evils without lending an ear to phantoms and monsters of our imagination...
