Progress

Argument, discussion and debate are referring to competition. All of them do their works by conflict, which often the oral style. People are easily influenced by emotion, and this is the reason that an rational argument turns into a brutal conflict. As we pay more attention to the outcome, the more sensitive we are. Victory is not the only thing from a debate. Debate is a stage of presentation that others can hear you. Most of us don't have this opportunity to ask people to listen, but debate can even make others listen to you carefully. It's a great chance to have a debate with others, this is how people get improvement from human civilization.
