Wow. What an asshole. I'm glad I read this classic now rather than high school - I see what Wilde is doing in the grotesque descriptions of food, drink, and conversation. The twist here is part of the anglophone zeitgeist, but how we get there is not, and Wilde takes his sweet time in classic Wildeian plotlessness. You don't read about Gray's Jekyll & Hyde-esque philandering, but you sure sense its effects, and the damaging of "reputation" is as damning as Victorian England could get. Intensely homoerotic as to be expected, and I'm very glad I finally read it during a cold camping weekend over Thanksgiving. 

Beautifully horrible.

From the Preface
"All art is at once surface and symbol. Those who go beneath it do so at their own peril. Those who read the symbol do so at their own peril. It is the spectator, and not life, that art really mirrors."

From Chapter 2
"Youth is the only thing worth having. When I find that I am growing old, I shall kill myself."

From Chapter 20
"As it had killed the painter, so it would kill the painter's work, and all that that meant. It would kill the past, and when that was dead he would be free. It would kill this monstrous soul-life, and without its hideous warnings, he would be at peace. He seized the thing, and stabbed the picture with it."

Final Scene
"Lying on the floor was a dead man, in evening dress, with a knife in his heart. He was withered, wrinkled, and loathsome of visage. It was not till they had examined the rings that they recognized who it was."

Review 
Oscar Wilde shows his artistic mastery through the preface, where he explores how we view art and warns against the danger of searching too deeply for hidden meanings. The Book follows Dorian's tragic journey after encountering someone(shall not be named) who views youth and beauty as life's most powerful attributes. This encounter leads to his obsession with maintaining his youth an obsession so profound that he declares he would rather die than grow old.

Ironically, this declaration becomes a self-fulfilling prophecy. In his final moments, Dorian believes that destroying the painting will solve everything, failing to realize that he himself is the artist's true masterpiece. He is both the art and the subject, the unchanging past incarnate, the monstrous soul he seeks to destroy. In attempting to find peace through the painting's destruction, he ultimately fulfills his earlier vow—he kills himself upon facing his own aging visage.

Dorian's fatal error lies in forgetting the books essential truth "Life itself was the first, the greatest, of the arts, and for it all the other arts seemed to be but a preparation." We must embrace life itself, not merely the temporary beauty of youth.
