We all know how Frodo would have trusted Boromir "but for the warning of his heart." But did you know that the elf-king Elrond was against sending Merry and Pippen along as members of the Fellowship, owing to the warnings of HIS heart? It's true... and Gandalf essentially told him HIS heart, the great elf-king's heart, spoke falsely, arguing for their inclusion with the weak argument that since you can't send a battalion into Mordor for it being sure to be noticed, you shouldn't think of military might at all when forming the Fellowship, and instead count on already established friendship. Yeah, 'cause it is SO apparent that not having another elf who can shoot down dragons or another human warrior who can take down dozens of orcs before going down, is but nothing if you've got a bit more of the accustomed and the familiar within your party -- 'cause who are kidding? friendship is born out of nothing again and again through their journeys.
