Romantic love presents some of life's most challenging questions. Can we choose who to love? Is romantic love rational? Can we love more than one person at a time? And can we make ourselves fall out of love? <br><br>In <em>On Romantic Love</em>, Berit Brogaard attempts to get to the bottom of love's many contradictions. This short book, informed by both historical and cutting edge philosophy, psychology, and neuroscience, combines a new theory of romantic love with entertaining anecdotes from real life and accessible explanations of the neuroscience underlying our wildest passions.<br><br>Against the grain, Brogaard argues that love is an emotion; that it can be, at turns, both rational and irrational; and that it can be manifested in degrees. We can love one person more than another and we can love a person a little or a lot or not at all. And love isn't even always something we consciously feel. However, love -- like other emotions, both conscious and not -- is subject to rational control, and falling in or out of it can be a deliberate choice. This engaging and innovative look at a universal topic, featuring original line drawings by illustrator Gareth Southwell, illuminates the processes behind heartbreak, obsession, jealousy, attachment, and more.
