There's the love train. And the love boat. And even a love shack. People have been singing about this "crazy little thing" for as far back as anyone can remember. Well "what's love but a second hand emotion" anyway? This month's From the Archive aims to find out.

The conversation begins with John and Ken asking philosopher and poet Jollimore, author of Love's Vision, just what is this thing called love. Next the Philosophers question how love could (or could not) ever be unconditional with Lynn Underwood from Cleveland State University, editor of The Science of Compassionate Love. This is followed by a discussion with renowned anthropologist Helen Fisher, author of Why We Love: The Nature and Chemistry of Romantic Love, about our culture's preference for monogamous romantic relationships, as well as a more recent program exploring the nature of polyamory with Carrie Jenkins from the University of British Columbia, author of What Love Is: And What It Could Be. The final episode explores the influence of Plato's Symposium -- arguably the most memorable philosophical work ever written on the subject of love -- on Leonard Bernstein’s gorgeous violin concerto, the Serenade.
