The nineteenth century dislike of realism is the rage of Caliban seeing his own face in a glass.The nineteenth century dislike of romanticism is the rage of Caliban not seeing his own face in a glass. The moral life of man forms part of the subject-matter of the artist, but the morality of art consists in the perfect use of an imperfect medium. No artist desires to prove anything. Even things that are true can be proved. No artist has ethical sympathies. An ethical sympathy in an artist is an unpardonable mannerism of style. No artist is ever morbid. The artist can express everything. Thought and language are to the artist instruments of an art. Vice and virtue are to the artist materials for an art. From the point of view of form, the type of all the arts is the art of the musician. From the point of view of feeling, the actor's craft is the type. All art is at once surface and symbol. Those who go beneath the surface do so at their peril. Those who read the symbol do so at their peril. It is the spectator, and not life, that art really mirrors. Diversity of opinion about a work of art shows that the work is new, complex, and vital. When critics disagree, the artist is in accord with himself. We can forgive a man for making a useful thing as long as he does not admire it. The only excuse for making a useless thing is that one admires it intensely.All art is quite useless.

Oscar Fingal O'Flahertie Wills Wilde (16 October 1854 30 November 1900) was an Irish poet and playwright. After writing in different forms throughout the 1880s, the early 1890s saw him become one of the most popular playwrights in London. He is best remembered for his epigrams and plays, his novel The Picture of Dorian Gray, and the circumstances of his criminal conviction for gross indecency for consensual homosexual acts in "one of the first celebrity trials", imprisonment, and early death from meningitis at age 46.
