Decadence, on the other hand, sees no path to higher truth in words and images. Instead, books, poetry, and art itself as the creators of valid new worlds, thus the allegory of decadent Wilde's Dorian Gray being poisoned by a book like a drug. Words and artifice are the vehicles for human creativity, and Huysmans suggests that the illusions of fantasy have their own reality: "The secret lies in knowing how to proceed, how to concentrate deeply enough to produce the hallucination and succeed in substituting the dream reality for the reality itself."
