Quant au bonheur, il n’a presque qu’une seule utilité, rendre le malheur possible.
Notes from Wikiquote
Ch. III: "An Afternoon Party at the House of the Princesse de Guermantes"
Happiness is beneficial for the body but it is grief that develops the powers of the mind.
The features of our face are hardly more than gestures become, by habit, permanent.
We are healed of a suffering only by experiencing it to the full.
