This episode is a discussion about the book "A General Theory of Love by Thomas Lewis, Fari Amini, and Richard Lannon.  Here is a summary of the book:

Three eminent psychiatrists tackle the difficult task of reconciling what artists and thinkers have known for thousands of years about the human heart with what has only recently been learned about the primitive functions of the human brain. The result is an original, lucid, at times moving account of the complexities of love and its essential role in human well-being. A General Theory of Love draws on the latest scientific research to demonstrate that our nervous systems are not self-contained: from earliest childhood, our brains actually link with those of the people close to us, in a silent rhythm that alters the very structure of our brains, establishes life-long emotional patterns, and makes us, in large part, who we are.
