Medellín's El Combiano newspaper quotes my definition of romantic love to argue that love arose to solve problems we had before we became who we now are, a beneficial solution that has caused other problems. My wife finds it funny that I am often quoted as an expert on romantic love. Regardless (of the problems love may cause or of my personal failings), the benefits of love surely outweigh the costs.
But, as Deirdre McCloskey enjoins us, we should not reduce love to material cost/benefit analyzes--such an approach does violence to the very concept. Rather, she argues, we should embrace love and incorporate it into economic models, for if we ignore the powerful motivation of love and regard for others we cannot begin to account for real human behavior.
