"You, who know better than any one the motley world of cosmopolites, understand why I have confined myself to painting here only a fragment of it. That world, indeed, does not exist, it can have neither defined customs nor a general character. It is composed of exceptions and of singularities. We are so naturally creatures of custom, our continual mobility has such a need of gravitating around one fixed axis, that motives of a personal order alone can determine us upon an habitual and voluntary exile from our native land. It is so, now in the case of an artist, a person seeking for instruction and change; now in the case of a business man who desires to escape the consequences of some scandalous error; now in the case of a man of pleasure in search of new adventures; in the case of another, who cherishes prejudices from birth, it is the longing to find the "happy mean;" in the case of another, flight from distasteful memories. The life of the cosmopolite can conceal all beneath the vulgarity of its whims, from snobbery in quest of higher connections to swindling in quest of easier prey, submitting to the brilliant frivolities of the sport, the sombre intrigues of policy, or the sadness of a life which has been a failure. Such a variety of causes renders at once very attractive and almost impracticable the task of the author who takes as a model that ever-changing society so like unto itself in the exterior rites and fashions, so really, so intimately complex and composite in its fundamental elements. The writer is compelled to take from it a series of leading facts, as I have done, essaying to deduce a law which governs them."

“I remember, the reasoning of a man determined to arrive that I tried to lull to sleep the inward voice that cried, "You have no right to put on paper, to give to the public what this noble writer said to you, supposing that he was receiving a poet, not a reporter." But I heard also the voice of my chief saying, "You will never succeed.”

“There is only one thing infamous in love, and that is a falsehood.”

“There is no such thing as an age for love ... because the man capable of loving — in the complex and modern sense of love as a sort of ideal exaltation — never ceases to love. I will go further; he never ceases to love the same person. You know the experiment that a contemporary physiologist tried with a series of portraits to determine in what the indefinable resemblances called family likeness consisted? He took photographs of twenty persons of the same blood, then he photographed these photographs on the same plate, one over the other. In this way he discovered the common features which determined the type. Well, I am convinced that if we could try a similar experiment and photograph one upon another the pictures of the different women whom the same man has loved or thought he had loved in the course of his life we should discover that all these women resembled one another. The most inconsistent have cherished one and the same being through five or six or even twenty different embodiments.”

“The contrast between the world of ideas in which he moved and the atmosphere of the literary shop in which for the last few months I had been stifling was too strong. The dreams of my youth were realized in this man whose gifts remained unimpaired after the production of thirty volumes and whose face, growing old, was a living illustration of the beautiful saying: "Since we must wear out, let us wear out nobly." His slender figure bespoke the austerity of long hours of work; his firm mouth showed his decision of character; his brow, with its deep furrows, had the paleness of the paper over which he so often bent; and yet, the refinement of his hands, so well cared for, the sober elegance of his dress and an aristocratic air that was natural to him showed that the finer professional virtues had been cultivated in the midst of a life of frivolous temptations. These temptations had been no more of a disturbance to his ethical and spiritual nature than the academic honors, the financial successes, the numerous editions that had been his.”

“When a man has been the lover of a woman as that man had been hers, with the vibrating communion of a voluptuousness unbroken for two years, that woman maintains a sort of physiological, quasi-animal instinct. A gesture, the accent of a word, a sigh, a blush, a pallor, are signs for her that her intuition interprets with infallible certainty. How and why is that instinct accompanied by absolute oblivion of former caresses? It is a particular case of that insoluble and melancholy problem of the birth and death of love.”

“Even after making up one's mind to the sacrifices I had decided upon, there is always left a trace of envy for those who have triumphed in the melancholy struggle for literary supremacy.”
