"The idea is the only control we have of reality."
Again:
"And on the top of a distant pine, solitary in the midst of a far-off glade, I heard the nightingale—unique voice of that silence....
"'Poetic' landscapes almost invariably leave me quite cold, seeing that for every serious man the most suggestive medium for ideas really poetic is no other than four walls, a table and silence. Those who do not carry within them the soul of everything the world can show them, will do well to watch it: they will not recognize it, each thing being beautiful only according to the thought of him who gazes at it and reflects it in himself. Faith is essential in poetry as in religion, and faith has no need of seeing with corporeal eyes to contemplate that which it recognizes much better in itself...."
Such ideas were many times, under multiple forms, always new, expressed by Villiers de L'Isle-Adam in his works. Without going as far as Berkeley's pure negations, which nevertheless are but the extreme logic of subjective idealism, he admitted in his conception of life, on the same plan, the Interior and the Exterior, Spirit and Matter, with a very visible tendency to give the first term domination over the second. For him the idea of progress was never anything but a subject for jest, together with the nonsense of the humanitarian positivists who teach, reversed mythology, that terrestrial paradise, a superstition if we assign it the past, becomes the sole legitimate hope if we place it in the future.
On the contrary, he makes a protagonist (Edison doubtless) say in a short fragment of an old manuscript of l'Ève future:
"We are in the ripe age of Humanity, that is all I Soon will come the senility and decrepitude of this strange polyp, and the evolution accomplished, his mortal return to the mysterious laboratory where all the Ghosts eternally work their experiments, by grace of some unquestionable necessity."
And in this last word, Villiers mocks his belief in God. Was he Christian? He became one towards the end of his life: thus he knew all the forms of intellectual intoxication.
