The Picture of Dorian Gray Chapter 20 Summary

Summary

Dorian Gray walks home on a warm night, reflecting on his notoriety, his ruined past, and Lord Henry's influence. He recalls the girl he once spared, Hetty Merton, and feels a sudden desire for purity and a new life; yet he also acknowledges the corruption he has sown and the pleasure he has taken in being an evil influence. Haunted by the portrait that bears the marks of his sins, he is alternately filled with remorse, pride, self-justification, and rationalizations about confession and punishment.

Tormented by conscience and hope, Dorian decides to test whether a genuine change of heart has altered the portrait. He unbars the locked room and, expecting to see improvement, is horrified to find the picture even more loathsome and bloodstained. Concluding that destruction of the portrait is the only way to kill his past and be free, he seizes the knife that had killed Basil Hallward and stabs the canvas. Servants hear a terrible cry; neighbors and a policeman are alerted. The household force entry and discover, hanging on the wall, the perfect youthful portrait of Dorian as he had been, while on the floor lies an old, withered, dead man in evening dress with a knife in his heart—recognized by his rings as Dorian Gray.

Analysis

This chapter serves as the moral and narrative climax of the novel, forcing Dorian to confront the visible record of his soul. Wilde uses tight, tense scenes to compress Dorian's internal oscillation between repentance and self-justification into decisive action—stabbing the portrait. The chapter foregrounds themes of hypocrisy, aestheticism as mask, and the impossibility of escaping consequences. The portrait functions as both externalized conscience and juridical evidence; its persistent corruption despite Dorian's verbal vows dramatizes the failure of mere affectation of virtue. Symbolically, the lamp, mirror, and the knife gather meaning: the lamp and mirror recall moments of self-recognition and vanity, while the murder-knife—instrument of Basil’s death—becomes an attempt at retroactive erasure. Wilde's narrative voice blends irony and moral intensity, letting Dorian rationalize even as the prose cues the reader to his delusions. Foreshadowing appears earlier in Dorian’s reflections on punishment and confession; structurally, the chapter ties together prior crimes (Basil’s murder, Alan Campbell’s suicide) and the portrait’s role as inevitable witness. The ambiguous last moments—youthful portrait versus aged corpse—compactly stage the novel’s critique of a culture that values surface beauty over moral substance, while leaving interpretation and judgment to the reader.

Important quotes

“He knew that he had tarnished himself, filled his mind with corruption and given horror to his fancy; that he had been an evil influence to others, and had experienced a terrible joy in being so;”

NarratorDorian admits his moral decline and the perverse pleasure he has taken in corrupting others—central to his self-reproach.

“It was his beauty that had ruined him, his beauty and the youth that he had prayed for.”

NarratorDorian blames the very gifts he desired—youth and beauty—for his downfall, revealing his paradoxical resentment of his own surface charm.

“As it had killed the painter, so it would kill the painter’s work, and all that that meant.”

NarratorDorian rationalizes destroying the portrait with the same instrument that killed Basil, treating the picture as the source of his guilt rather than the evidence of his action.
