In a sense, the discipline of communication is all about peace. This is so because the discipline seeks to explain the relationship between communication and understanding as well as to promote better understanding through instruction in effective communication practices. Thus, all sub-disciplines of communication-from organizational communication to public address to health communication-address both theoretical and practical questions about how communication assists or frustrates human understanding. To the extent that an understanding serves as an antidote to human conflict, then, communication seeks to promote peace.
