What a profound significance small things assume when the woman we love conceals them from us.

Women who are to some extent resistant, whom one cannot possess at once, whom one does not even know at first whether one will ever possess, are the only interesting ones.

The places we have known do not belong solely to the world of space in which we situate them for our greater convenience. They were only a thin slice among contiguous impressions which formed our life at that time; the memory of a certain image is but regret for a certain moment; and houses, roads, avenues are as fleeting, alas, as the years.

The moments of the past do not remain still; they retain in our memory the motion which drew them towards the future, towards a future which has itself become the past, and draw us on in their train.

Even in the most insignificant details of our daily life, none of us can be said to constitute a material whole, which is identical for everyone, and need only be turned up like a page in an account-book or the record of a will; our social personality is created by the thoughts of other people.

It is in moments of illness that we are compelled to recognize that we live not alone but chained to a creature of a different kingdom, whole worlds apart, who has no knowledge of us and by whom it is impossible to make ourselves understood: our body.

Pleasures are like photographs: in the presence of the person we love, we take only negatives, which we develop later, at home, when we have at our disposal once more our inner dark room, the door of which it is strictly forbidden to open while others are present.
