Is there a constant battle between our immune system and pathogens? Does the fighting ever end? Does the immune system do more than just provide defense against pathogens?

Tune into this podcast to hear Art and Marty talk to Fred Tauber, a professor emeritus of medicine and philosophy at Boston University, about how the immune system does more than just protect our bodies from pathogens.

Fred has published a number of books on immunity and philosophy. Including his most recent book, "Immunity: the Evolution of an Idea," where he explores the ideas he discusses here in greater detail.
