Love is a flame, and the good teacher raises in students a burning desire for his or her approval and attention, his or her voice and presence, that is" erotic in its urgency and intensity. The professor ignites these feelings just by standing in front of a classroom talking about Shakespeare or anthropology or physics, but the fruits of the mind are that sweet, and intellect has the power to call forth new forces in the soul. Students will sometimes mistake this earthquake for sexual attraction, and the foolish or inexperienced or cynical instructor will exploit that confusion for his or her own gratification. But the great majority of professors understand that the art of teaching consists not only of arousing desire but of redirecting it toward its proper object, from the teacher to the thing taught."
