“It's a good idea to carry a small mirror in your pocket, which will give you a reflection of yourself before you judge others.”

Un roman est un miroir qui se promène sur une grande route. Tantôt il reflète à vos yeux l’azur des cieux, tantôt la fange des bourbiers de la route. Et l’homme qui porte le miroir dans sa hotte sera par vous accusé‚ d’être immoral ! Son miroir montre la fange, et vous accusez le miroir! Accusez bien plutôt le grand chemin où est le bourbier, et plus encore l’inspecteur des routes qui laisse l’eau croupir et le bourbier se former.
Vol. II, ch. XIX

Context: Art is the magic mirror you make to reflect your invisible dreams in visible pictures. You use a glass mirror to see your face: you use works of art to see your soul. But we who are older use neither glass mirrors nor works of art. We have a direct sense of life. When you gain that you will put aside your mirrors and statues, your toys and your dolls.
