"All art," Oscar Wilde once announced, "is quite useless." Selected here are some of his finest prose works on the subject of art - useless, illuminating, artificial, uplifting, radical, gorgeous, boring, sublime - and his most brilliant aphorisms on the creative life. Whether lamenting the crass urge to hold art to realist or natural standards or arguing against morality as a guiding principle, Wilde defends the artist while delighting the audience.
