<DIV><p>We seem to be abandoning the codes that told previous generations who they should love. But now that many of us are free to choose whoever we want, nothing is less certain. The proliferation of divorces and separations reveal a dynamic we would rather not see: others sometimes reject us as passionately as we are attracted to them.<BR>      Our desire makes us sick. The throes of rivalry are at the heart of our attraction to one another. This is the central thesis of Jean-Michel Oughourlian's <I>The Genesis of Desire</I>, where the war of the sexes is finally given a scientific explanation. The discovery of mirror neurons corroborates his ideas, clarifying the phenomena of empathy and the mechanisms of violent reciprocity.<BR>      How can a couple be saved when they have declared war on one another? By helping them realize that desire originates not in the self but in the other. There are strategies that can help, which Dr. Oughourlian has prescribed successfully to his patients. This work, alternating between case studies and more theoretical statements, convincingly defends the possibility that breakups need not be permanent.<BR>  </p></DIV>
