Why might Krauss have given her novel the title The History of Love, the same as that of the fictional book around which her narrative centers?

I believe Krauss may have been somewhat overly ambitious in this particular choice. It seems clear that her attempt to subvert her character Leo’s interpretation of love by adding in the narration and perspective of other characters and their views of love. The result is a complex and often contradictory account of the human experience and the differences with which each of us approaches the nature of love. While some, who may have chosen the books hoping to discover a definitive truth about the nature of love and how it functions in society, may have been left disappointed by Krauss’ inability to deliver, but perhaps this is even more honest.
