The Importance of Being Earnest by Oscar Wilde

Algernon's throwaway quip to Lane that "anyone can play [piano] accurately but I play with wonderful expression" is a good thumbnail of Wilde's philosophy of art. Wilde was heavily influenced by Walter Pater and the other aesthetes of the Victorian age. They believed art should concern itself only with its aesthetic qualities, that art should exist for art's sake alone. Therefore, art should not be a straightforward representation of reality--it should not be "accurate," as Algernon would say--but rather it should be an extension of its creator's artistic styles. Hence, it should have "wonderful expression."
