Lord Henry is a man possessed of “wrong, fascinating, poisonous, delightful theories.” He is a charming talker, a famous wit, and a brilliant intellect. Given the seductive way in which he leads conversation, it is little wonder that Dorian falls under his spell so completely. Lord Henry’s theories are radical; they aim to shock and purposefully attempt to topple established, untested, or conventional notions of truth. In the end, however, they prove naïve, and Lord Henry himself fails to realize the implications of most of what he says.
Lord Henry is a relatively static character—he does not undergo a significant change in the course of the narrative. He is as coolly composed, unshakable, and possessed of the same dry wit in the final pages of the novel as he is upon his introduction. Because he does not change while Dorian and Basil clearly do, his philosophy seems amusing and enticing in the first half of the book, but improbable and shallow in the second. Lord Henry muses in Chapter Nineteen, for instance, that there are no immoral books; he claims that “[t]he books that the world calls immoral are books that show the world its own shame.” But since the decadent book that Lord Henry lends Dorian facilitates Dorian’s downfall, it is difficult to accept what Lord Henry says as true.
Although Lord Henry is a self-proclaimed hedonist who advocates the equal pursuit of both moral and immoral experience, he lives a rather staid life. He participates in polite London society and attends parties and the theater, but he does not indulge in sordid behavior. Unlike Dorian, he does not lead innocent youths to suicide or travel incognito to the city’s most despised and desperate quarters. Lord Henry thus has little notion of the practical effects of his philosophy. His claim that Dorian could never commit a murder because “[c]rime belongs exclusively to the lower orders” demonstrates the limitations of his understanding of the human soul. It is not surprising, then, that he fails to appreciate the profound meaning of Dorian’s downfall.
