“How inferior the human machine is, compared to man-made machines. They can be decoked, unscrewed, oiled and parts replaced. Decidedly, nature is not a very wonderful thing.”

“There is not one single invention of (Nature's), however subtle or impressive it may be thought to be, that the human spirit cannot create; no forest of Fontainebleu or moonlit scene that cannot be produced with a floodlit stage set; no waterfall that hydraulics cannot imitate so perfectly as to be indistinguishable from the original; no rock that papier-mâché cannot copy; no flower that specious taffetas and delicately painted papers cannot rival! There is no doubt whatever that this eternally self-replicating old fool has now exhausted the good-natured admiration of all true artists, and the moment has come to replace her, as far as that can be achieved, with artiface.”

“...indeed it is very true that, just as the finest air in the world is vulgarized beyond all bearing once the public has taken to hum it and the street organs to play it, so the work of art that has appealed to the sham connoisseurs, that is admired by the uncritical, that is not content to rouse the enthusiasm of only a chosen few, becomes for this very reason, in the eyes of the elect, a thing polluted, commonplace, almost repulsive.”

“literature, in fact, had been concerned with virtues and vices of a perfectly healthy sort, the regular functioning of brains of a normal conformation, the practical reality of current ideas, with never a thought for morbid depravities and other-worldly aspirations; in short, the discoveries of these anaylists of human nature stopped short at the speculations good or bad, classified by the church; their efforts amounted to no more than the humdrum researches of a botanist who watches closely the expected development of ordinary flora planted in common or garden soil.”

“His contempt for humanity grew fiercer, and at last he came to realize that the world is made up mostly of fools and scoundrels. It became perfectly clear to him that he could entertain no hope of finding in someone else the same aspirations and antipathies; no hope of linking up with a mind which, like his own, took pleasure in a life of studious decrepitude; no hope of associating an intelligence as sharp and wayward as his own with any author or scholar.”

“I wish to confound all these people, to create a work of art of a supernatural realism and of a spiritualist naturalism. I wish to prove... that nothing is explained in the mysteries which surround us.”

“The belief that man is an irresolute creature pulled this way and that by two forces of equal strength, alternately winning and losing the battle for his soul; the conviction that human life is nothing more than an uncertain struggle between heaven and hell; the faith in two opposed entities, Satan and Christ - all this was bound to engender those internal discords in which the soul, excited by the incessant fighting, stimulated as it were by the constant promises and threats, ends up by giving in and prostitutes itself to whichever of the two combatants has been more obstinate in its pursuit.”
