Discussion or Dialogue?

Which of these descriptions best characterizes your Board meetings?
Discussion: from the same root word as percussion and concussion. Literally means, "to break apart." According to Peter Senge, "Discussion involves heaving one's views at another … a cacophony of voices battling it out to see who wins and who loses."
Dialogue: from the Greek "dia-logos," meaning "through the meaning or word." It involves the "flow of meaning." People in dialogue are unconcerned about who says what, about whose view prevails, or who saves face. They enter the domain of truly thinking together.
