There is no such thing as a good influence, Mr. Gray. All influence is immoral – immoral from the scientific point of view.
– Oscar Wilde
The Picture of Dorian Gray, Chapter 2. When Dorian asks if Lord Henry really has as bad an influence over his friends as Basil claims, Henry makes this reply. He decries influence as immoral, which is rather ironic, because Henry sets out to heavily influence the impressionable Dorian and mold him to his way of thinking.
