The novels of Huysmans, however we may regard them as novels, are, at all events, the sincere and complete expression of a very remarkable personality. From _Marthe_ to _Là-Bas_ every story, every volume, disengages the same atmosphere--the atmosphere of a London November, when mere existence is a sufficient burden, and the little miseries of life loom up through the fog into a vague and formidable grotesqueness. Here, for once, is a pessimist whose philosophy is mere sensation--and sensation, after all, is the one certainty in a world which may be well or ill arranged, for ultimate purposes, but which is certainly, for each of us, what each of us feels it to be. To Huysmans the world appears to be a profoundly uncomfortable, unpleasant, ridiculous place, with a certain solace in various forms of art, and certain possibilities of at least temporary escape. Part of his work presents to us a picture of ordinary life as he conceives it, in its uniform trivial wretchedness; in another part he has made experiment in directions which have seemed to promise escape, relief; in yet other portions he has allowed himself the delight of his sole enthusiasm, the enthusiasm of art. He himself would be the first to acknowledge--indeed, practically, he has acknowledged that the particular way in which he sees life is a matter of personal temperament and constitution, a matter of nerves. The Goncourts have never tired of insisting on the fact of their _névrose,_ of pointing out its importance in connection with the form and structure of their work, their touch on style, even. To them the _maladie fin de siècle_ has come delicately, as to the chlorotic fine ladies of the Faubourg Saint-Germain: it has sharpened their senses to a point of morbid acuteness, it has given their work a certain feverish beauty. To Huysmans it has given the exaggerated horror of whatever is ugly and unpleasant, with the fatal instinct of discovering, the fatal necessity of contemplating, every flaw and every discomfort that a somewhat imperfect world can offer for inspection. It is the transposition of the ideal. Relative values are lost, for it is the sense of the disagreeable only that is heightened; and the world, in this strange disorder of vision, assumes an aspect which can only be compared with that of a drop of impure water under the microscope. "Nature seen through a temperament" is Zola's definition of all art. Nothing, certainly, could be more exact and expressive as a definition of the art of Huysmans.
