Relating Reason and Emotions in Knowing

Hodges and Vowell have a conversation with Dr. E. Calvin Beisner, in which they discuss the way truth is understood.  Do we follow reason or emotion?  Are they two different ways to know?  In debates are we missing each other because one side is reasoning and the other is feeling?  The problem arises in more than debates about global warming, it becomes a key element of discussions about sex and marriage, abortion, economics, tax plans, sexual abuse of women and children, gun control...each side thinks he is reasoning, but more often than not, no amount of reasoning will change minds anymore.  How can very real emotions be related to very real facts?
