When the novel was republished, Wilde added a preface as a form of rebuttal, which should be required reading for all critics today. In it, he explains that vice and virtue are simply ‘materials’ for artists, reminding us that the depiction of immorality is not necessarily an endorsement of such behaviour. Even if it were, why should it matter? ‘There is no such thing as a moral or an immoral book’, Wilde proclaims. ‘Books are well written, or badly written. That is all.’
