After a certain age our memories are so intertwined with one another that what we are thinking of, the book we are reading, scarcely matters any more. We have put something of ourselves everywhere, everything is fertile, everything is dangerous, and we can make discoveries no less precious than in Pascal's Pensées in an advertisement for soap.

Indeed, among the lesser auxiliaries to success in love, an absence, the declining of an invitation to dinner, an unintentional, unconscious harshness are of more service than all the cosmetics and fine clothes in the world.

Man is the creature that cannot emerge from himself, that knows his fellows only in himself; when he asserts the contrary, he is lying.

When you work to please others you can't succeed, but the things you do to satisfy yourself stand a chance of catching someone's interest.

The creation of the world did not occur at the beginning of time, it occurs every day.

Now the same mystery which often veils from our eyes the reason for a catastrophe envelops just as frequently, when love is in question, the suddenness of certain happy solutions, such as had been brought to me by Gilberte's letter. Happy, or at least seemingly happy, for there are few that can really be happy when we are dealing with a sentiment of such a kind that any satisfaction we can give it does no more, as a rule, than dislodge some pain. And yet sometimes a respite is granted us, and we have for a little while the illusion of being healed.

For one cannot change, that is to say become another person, while continuing to acquiesce to the feelings of the person one no longer is.
