The first piece, 'The Decay of Lying,' takes the form of a lively dialogue between two friends in a country library, where one defends the provocative thesis that art should never imitate life or nature. Instead, Wilde argues that art shapes its own perfect world and that, conversely, human life and nature slavishly imitate the brilliant inventions of painters and poets. He laments the modern obsession with crude facts and realism, asserting that imagination, style, and beautiful untruths are the true foundations of civilized culture and aesthetic pleasure.
In 'Pen, Pencil, and Poison,' Wilde examines the extraordinary double life of Thomas Griffiths Wainewright, an English dandy, art critic, essayist, and secret poisoner of the nineteenth century. This biographical study explores how a man of refined aesthetic tastes and genuine love for literature could simultaneously harbor a cold talent for forgery and multiple murders. Wilde suggests that there is no essential incongruity between crime and culture, analyzing the killer through a lens of artistic fascination rather than conventional moral judgment.
The dialogue 'The Critic as Artist' elevates criticism from a subsidiary craft into an independent, creative art form of the highest order. Set in a London library overlooking the Green Park, the discussion posits that the true critic does not merely explain a work of art, but uses it as a starting point for a new personal creation. Wilde contends that contemplation is the most intellectual occupation of man, far superior to the blind, practical activity of action, and urges an escape from the sordid urgencies of actual life into the serene realm of beauty.
The final essay, 'The Truth of Masks,' investigates the importance of archaeological accuracy and costume in the production of Shakespearean drama. Wilde demonstrates through extensive textual analysis that Shakespeare was deeply concerned with the visual details of dress, viewing costume not as mere pedantry, but as an essential element of dramatic illusion. He concludes that the union of accurate historical detail with imaginative presentation is vital for bringing the past to vivid life on the modern stage.
