The importance of being constant (1895), the last of Oscar Wilde's four light comedies, is probably the most played piece in the English repertoire. It is a joyous farce, where the author's spirit is free to act, with its paradoxes and humour, mixing the most unsettled absurd with the most delicate sentimental fantasy. Jack, the main character, pretends to be another, borrowing Constant's foreword, but he is caught in his own trap in an endless comical imbroglio. This comedy is also a satire of Victorian society, of his cult of money, of name, of birth and especially of seriousness, of the moral rectitude that leads to hypocrisy. Wilde wondered about the very short identity, as a precursor to the modern theatre to which he was already close, as he played with the dramatic conventions.
