Debate encourages you to criticize others. Dialogue promotes open-mindedness, including an openness to being wrong. Debate creates a close-minded attitude, a determination to be right. Dialogue encourages you to see all sides of an issue. Debate encourages you to see only two different sides of an issue.
Dialogue invites keeping the topic open after the discussion formally ends.
Debate, by creating a winner and a lose, discourages further discussion. Reprinted with permission from Dialogue 1997 Educators for Social Responsibility.
