A perverse nature can be stimulated by anything. Any book can be used as a pornographic instrument, even a great work of literature if the mind that so uses it is off-balance. I once found a small boy masturbating in the presence of the Victorian steel-engraving in a family Bible.
Anthony BurgessAs a chamber hung round about with looking-glasses represents the face upon every turn, thus all the world doth the mercy and the bounty of God; though that be visible, yet it discovers an invisible God and his invisible properties.
Anthony BurgessThere is, in fact, not much point in writing a novel unless you can show the possibility of moral transformation, or an increase in wisdom, operating in your chief character or characters. Even trashy bestsellers show people changing. When a fictional work fails to show change, when it merely indicates that human character is set, stony, unregenerable, then you are out of field of the novel and into that of the fable or the allegory. - from the introduction of the 1986 Norton edition
