‘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.
