Context

“She pictured herself living at Paris, and continuing to give her sons an education which would make them admired by everyone. Her children, herself, and Julien! They would be all perfectly happy! Strange result of marriage such as the nineteenth century has made it! The boredom of matrimonial life makes love fade away inevitably, when love has preceded the marriage. But none the less, said a philosopher, married life soon reduces those people who are sufficiently rich not to have to work, to a sense of being utterly bored by all quiet enjoyments. And among women, it is only arid souls whom it does not predispose to love.” source
