"Within a single scene, it seems to be unwise to have access to the inner reflections of more than one character. The reader generally needs a single character as the means of perception, as the character to whom the events are happening, as the character with whom he is to empathize in order to have the events of the writing happen to him."

You little know what you have done, when you have first broke the bounds of modesty; you have set open the door of your fancy to the devil, so that he can, almost at his pleasure ever after, represent the same sinful pleasure to you anew; he hath now access to your fancy to stir up lustful thoughts and desires, so that when you should think of your calling, of your God, or of your soul, your thoughts will be worse than swinish, upon the filth that is not fit to be named. If the devil here get in a foot, he will not easily be got out.
