One morning indeed, I felt a sudden misgiving that she not only had left the house but had gone for good: I had just heard the sound of a door which … - Marcel Proust

O ciúme nada mais é muitas vezes do que uma inquieta necessidade de tirania aplicada às coisas do amor.

The relations one has with a woman one loves (and that can apply also to love for a youth) can remain platonic for other reasons than the chastity of the woman or the unsensual nature of the love she inspires. The reason may be that the lover is too impatient and by the very excess of his love is unable to await the moment when he will obtain his desires by sufficient pretence of indifference. Continually, he returns to the charge, he never ceases writing to her whom he loves, he is always trying to see her, she refuses herself, he becomes desperate. From that time she knows, if she grants him her company, her friendship, that these benefits will seem so considerable to one who believed he was going to be deprived of them, that she need grant nothing more and that she can take advantage of the moment when he can no longer bear being unable to see her and when, at all costs, he must put an end to the struggle by accepting a truce which will impose upon him a platonic relationship as its preliminary condition. Moreover, during all the time that preceded this truce, the lover, in a constant state of anxiety, ceaselessly hoping for a letter, a glance, has long ceased thinking of the physical desire which at first tormented him but which has been exhausted by waiting and has been replaced by another order of longings more painful still if left unsatisfied. The pleasure formerly anticipated from caresses will later be accorded but transmuted into friendly words and promises of intercourse which brings delicious moments after the strain of uncertainty or after a look impregnated with such coldness that it seemed to remove the loved one beyond hope of his ever seeing her again. Women divine all this and know they can afford the luxury of never yielding to those who, from the first, have betrayed their inextinguishable desire. A woman is enchanted if, without giving anything, she can receive more than she generally gets when she does give herself.

Every reader finds himself. The writer's work is merely a kind of optical instrument that makes it possible for the reader to discern what, without this book, he would perhaps never have seen in himself.
