"A line is a path that can offer an interesting and varied journey; rhythmic and with occasional, pleasurable surprises. Thus one is tempted to take the journey again. This is as true for a line of music by Mozart or Gershwin as for the skyline of Salisbury Cathedral or the Taj Majal. It is absolutely vital to the sales of a popular car, a hi-fi radio, a camera, or an evening dress. From the hand of a Toulouse-Lautrec, a Michelangelo or a Picasso, a line becomes a poem of infinite sensitivity with a bitter-sweet irony inflected by compassion and love."
